Financial planning questions, worked through

1. How much does a smaller EMI cost over time?

Suppose you borrow ₹8,00,000 at a fixed 9.5% annual rate. Keep the amount and rate unchanged and compare three repayment terms. Interest uses the monthly reducing balance, with the first payment one month after disbursement.

Moving from three to seven years lowers the monthly payment by ₹12,551, but adds ₹1,75,767 in interest. That is the cost of spreading repayment over another four years under these assumptions.

Reproduce and check it

1. Open the EMI calculator. Enter ₹8,00,000 and 9.5%.
2. Set the term to 3, 5 and 7 years in turn. Compare total interest alongside EMI.
3. Inspect the monthly schedule. The first month’s interest is ₹6,333 when rounded, and interest falls as principal is repaid.

Actual offers may include fees, insurance, irregular payment dates and rate resets, all excluded here. Compare these terms with the lender. A manageable EMI depends on your other commitments; the calculation alone cannot establish affordability or approval.

2. How much of an investment result depends on the assumed return?

Consider ₹5,000 invested at the beginning of each month for ten years. Contributions total ₹6,00,000 in every scenario. The annual assumed rate is divided by twelve, with monthly compounding and no missed deposits.

The gap between the 6% and 10% scenarios is ₹2,09,266 despite identical contributions. The gap comes entirely from the assumption. The 0% row separates deposits from assumed growth; it is not a worst-case floor. Investments can lose value.

Reproduce and check it

Open the ₹5,000 monthly, ten-year, 6% scenario, then change the rate to 0% and 10%. If a goal only works at the higher rate, explore changing contributions or the deadline instead of treating the higher return as certain.

The model applies a smooth rate each month. Actual returns vary, and their sequence can affect recurring investments. Taxes, charges and inflation are excluded. These rates demonstrate sensitivity and are not forecasts for a product. See SEBI’s investor education resources for investment risk information.

3. What does a future amount buy in today’s money?

A household spending ₹30,000 monthly on a fixed basket would need approximately ₹53,725 per month after ten years at an assumed 6% annual inflation rate. The calculation is ₹30,000 × 1.06¹⁰. It excludes any increase in the quantity or quality of purchases.

Reverse the calculation: ₹10,00,000 received in ten years has purchasing power of approximately ₹5,58,395 today at the same inflation assumption. Divide by the inflation factor to convert future money to today’s money; multiply to convert a present expense to its future cost.

Reproduce and check it

Use the inflation calculator with ₹30,000, 6% and ten years. Repeat at 4% and 8%. Then explore expenses and assumed returns together in the retirement calculator.

Six percent is an illustration, not a claim about current or future Indian inflation. Your spending basket may change at a different rate. A nominal 8% return with 6% inflation produces a real return of approximately 1.89%, using (1.08 ÷ 1.06) − 1. Subtracting rates gives only an approximation.

United Kingdom: Are you comparing money available now with money set aside for retirement?

A cash savings goal and a SIPP balance answer different questions. The SIPP model includes basic-rate relief under its stated assumptions, while the savings tool excludes tax and account restrictions. Keep accessible savings separate from a retirement balance when comparing the results.

Reproduce this fictional profile: Current balance: £10,000; Your monthly payment (net, relief at source): £300; Monthly employer contribution: £200; Assumed annual return (nominal): 5%; Years: 20.

• Projected balance: £263,470.76
• Basic-rate relief added annually: £900.00
• Opening balance + credited contributions: £148,000.00

Open Private pension / SIPP calculator. Relief-at-source private pension/SIPP illustration: your net payment is divided by 0.8, adding basic-rate relief; employer payments are added separately. Enter an assumed annual return after fees. No further higher-rate relief, salary sacrifice, State Pension or withdrawal tax is modelled. The standard annual allowance is £60,000 in 2026–27; tapering, relevant earnings, money purchase annual allowance and carry-forward can change your position. Eligibility for relief is not assessed. Future contributions and limits are held constant.

United States: Does your comparison include your employer contribution?

An ordinary investment projection does not add a 401(k) employer contribution. Enter the actual contribution in the dedicated 401(k) tool, then compare balances with the same return and horizon. The federal tax tool excludes state and local taxes, so its result cannot establish the cash available for saving.

Reproduce this fictional profile: Current balance: $10,000; Your monthly employee deferral: $300; Monthly employer contribution: $200; Assumed annual return (nominal): 5%; Years: 20.

• Projected balance: $232,643.24
• Opening balance + credited contributions: $130,000.00
• Modelled growth: $102,643.24

Open 401(k) calculator. Traditional 401(k) balance illustration for a participant under 50 throughout the scenario. Enter your monthly elective deferral and the actual monthly employer contribution, not a match percentage. Uses the 2026 employee limit of $24,500 and combined limit of $72,000 as checks, held constant in future years. Compensation, vesting, plan-specific limits, catch-up contributions, Roth rules, Social Security and withdrawal taxes are excluded. Return is your assumption after fees, before withdrawal tax.

France: Are you entering taxable income or the salary on your contract?

The French tax tool expects revenu net imposable after applicable deductions; it does not subtract the salary deduction again. For PER planning, use the personal deduction ceiling from your tax notice. A projected PER balance is not the cash you would receive after exit taxes.

Reproduce this fictional profile: Current balance: 10 000 €; Monthly contribution: 300 €; Assumed annual return (nominal): 5%; Years: 20.

• Projected balance: 150 436,50 €
• Opening balance + credited contributions: 82 000,00 €
• Modelled growth: 68 436,50 €

Open Individual PER calculator. Individual PER accumulation from voluntary payments. Monthly contributions are credited at month end. Return is an assumption after fees and before exit taxes. Contributions are not automatically treated as fully tax-deductible: use the personal deduction ceiling on your tax notice. This projection excludes tax relief, exit taxation, annuity pricing, mandatory pensions and employer-plan transfers. A projected balance is not a guaranteed pension income.

Germany: Are you comparing a pension payment with an investment balance?

The German pension-points tool estimates a monthly statutory payment under its stated assumptions. An investment calculator instead projects a stock of assets. Compare income with income: do not add a monthly pension directly to a capital balance or assume the pension estimate covers every insurance deduction.

Reproduce this fictional profile: Accumulated pension points (Entgeltpunkte): 20; Assumed additional points per year: 1; Further contribution years: 20; Access factor (Zugangsfaktor): 1.

• Gross monthly old-age pension at current point value: 1.700,80 €
• Projected total points: 40.00
• Monthly value per point (July 2026): 42,52 €

Open Statutory pension points calculator. Statutory old-age pension illustration from your accumulated Entgeltpunkte and assumed future annual points. Uses the €42.52 monthly point value effective 1 July 2026 through 30 June 2027, held constant. The pension-type factor is 1 for an old-age pension. Enter the access factor from your pension statement, or 1 for no adjustment. Future revaluations, eligibility, health/care contributions and income tax are excluded. This is a gross monthly illustration at the current point value, not a forecast of future pension rates.

Australia: Is the salary figure inclusive or exclusive of super?

The super tool expects qualifying salary excluding super and treats voluntary payments as concessional salary sacrifice. Avoid entering a total remuneration package as salary and then adding super again. Its balance excludes insurance and is different from an accessible savings goal.

Reproduce this fictional profile: Current balance: $10,000; Annual qualifying earnings, excluding super: $80,000; Monthly salary sacrifice (before contributions tax): $200; Assumed annual return (nominal): 5%; Years: 20.

• Projected balance: $376,505.02
• Annual employer SG contribution: $9,600.00
• Annual contributions tax (15%): $1,800.00

Open Superannuation calculator. Accumulation-phase super illustration in a taxed fund: employer SG is 12% of entered qualifying earnings, limited to the 2026–27 annual maximum contribution base of $270,830. Salary excludes super. Voluntary payments here are concessional salary sacrifice. Contributions are reduced by 15% tax. The $32,500 annual concessional cap is checked, with no carry-forward. Enter a return after investment taxes and fees. Division 293, LISTO, insurance, Age Pension and withdrawal rules are excluded. Earnings, limits and contribution rates are held constant for the projection.

Canada: Are you comparing a mortgage term with its amortization period?

Use the amortization period in the payment calculator. The Canadian fixed-rate Home Loan model converts a semi-annually compounded quoted rate to monthly payments, but holds it unchanged across the illustration. A renewal at a different rate changes the remaining schedule. The RRSP tool separately requires your own available contribution room.

Reproduce this fictional profile: Current balance: $10,000; Monthly contribution: $300; Monthly employer RRSP contribution: $0; Available annual RRSP contribution room (assumed each year): $10,000; Age at start: 35; Assumed annual return (nominal): 5%; Years: 20.

• Projected balance: $150,436.50
• Opening balance + credited contributions: $82,000.00
• Modelled growth: $68,436.50

Open RRSP calculator. RRSP accumulation, not CPP/OAS or a pension-income entitlement. Enter available contribution room from your CRA records and assume that same room is available each projected year. Employee and employer RRSP contributions both consume that room; tax deductions/refunds, unused-room calculations, the $2,000 excess-contribution tolerance and withdrawal taxes are not modelled. The 2026 new-room dollar ceiling is $33,810, but actual room can differ with earned income, pension adjustments and carry-forward, so no universal room is assumed. Contributions are monthly at month end; return is an assumption after fees. Projection must end by age 71; RRIF conversion is excluded.

New Zealand: Have you separated contributions from the return assumption?

The KiwiSaver model separates employee, employer and eligible government contributions, including its stated rate transition. Do not replace those contributions with the assumed investment return. Compare employer amounts after the selected ESCT treatment and check the government eligibility choice before interpreting the balance.

Reproduce this fictional profile: Current balance: $10,000; Annual gross salary (held constant): $60,000; Annual total taxable income for government eligibility: $60,000; Age at start: 35; Employee contribution rate (2026): 3.5%; Employer contribution rate before ESCT (2026): 3.5%; Your applicable ESCT rate (check with payroll): 30%; Eligible for full-year government contribution throughout?: No / unsure — exclude government contribution; Assumed annual return after fund tax and fees: 5%; Years: 20.

• Projected balance: $164,564.32
• Opening balance + credited contributions: $90,707.50
• Modelled growth: $73,856.82

Open KiwiSaver calculator. KiwiSaver accumulation starts 1 July 2026 with constant salary and total taxable income. Employee and gross employer rates are selected from the supported standard rates; temporary 3% reductions are excluded. A selected 3.5% rate increases to 4% in April 2028 (month 22); higher selected rates stay unchanged. Employer contributions are reduced by your selected ESCT rate: check the correct rate with payroll, as salary alone does not establish it. Return is assumed after fund tax and fees. Government contributions are OFF unless you confirm full-year eligibility throughout the projection; then 25% of employee contributions, capped at $260.72, is credited each June if entered total taxable income is no more than $180,000. This is a year-end timing simplification, not an actual payment date. Part-year eligibility, salary growth, savings suspensions, first-home withdrawals and NZ Super are excluded. End the projection by age 65. Future rules other than the scheduled 2028 increase are held constant.

Singapore: Are regular wages the only pay you are modelling?

The CPF tool covers the stated Ordinary Wage profile and ends accumulation by age 55. Bonuses, Additional Wages and account transfers need separate treatment. Its assumed blended return is not a forecast for each CPF account, and the resulting balance is not a CPF LIFE monthly payout.

Reproduce this fictional profile: Current balance: $10,000; Monthly Ordinary Wages (no bonuses): $5,000; Age at start: 30; Assumed blended annual return (not account rates): 3%; Years: 20.

• Projected balance: $625,566.25
• Opening balance + credited contributions: $454,000.00
• Modelled growth: $171,566.25

Open CPF calculator. Combined CPF balance illustration for a Singapore citizen or PR from the third year onwards, using full January 2026 contribution rates. Models Ordinary Wages only, capped at $8,000 per month, with no bonuses/Additional Wages, voluntary top-ups or other employment. For ages 55 and below, total contributions are 37% and employee contributions 20% above $750 wages; statutory low-wage bands are included. Total contributions round to the nearest dollar and the employee share rounds down; employer share is the difference. Salary and rates are held constant, and the projection must end by age 55. The assumed blended return is a user illustration, not an official CPF interest rate. Account allocation, OA housing withdrawals, MediSave spending, retirement-account transfers, CPF LIFE, eligibility for withdrawals and future rule changes are excluded; the combined balance is not freely withdrawable cash.

Ireland: What changes when you contribute to a PRSA?

Compare the PRSA tool’s first-year eligible contribution and income-tax saving with its projected fund. The pay calculator excludes PRSA deductions and MyFutureFund, so the two headline results cannot simply be added together to create a payslip. Age and relevant earnings affect the relief illustration.

Reproduce this fictional profile: Current balance: €10,000; Monthly contribution: €300; Annual relevant employment earnings: €60,000; Age at end of first tax year: 35; Assumed annual return (nominal): 5%; Years: 20.

• Projected balance: €150,436.50
• Opening balance + credited contributions: €82,000.00
• Modelled growth: €68,436.50

Open PRSA calculator. Personal PRSA accumulation from employee contributions only. The first-year income-tax-relievable amount uses the age-related earnings percentage (15%, 20%, 25%, 30%, 35%, 40%) and the EUR 115,000 earnings ceiling. First-year income-tax saving assumes the same single PAYE profile as the tax calculator; there is no USC/PRSI relief or refund reinvestment. All contributions are invested, including any amount above the relief ceiling. Future tax relief is not projected. End the accumulation period by age 75; deemed vesting and imputed distributions are not modelled. Return is an assumed nominal annual rate after fees, compounded monthly; contributions arrive at month end. Employer contributions, other pension arrangements using the same relief limit, State Pension, MyFutureFund, drawdown taxes and benefit limits are excluded.

South Africa: Is the retirement contribution affordable from your actual monthly pay?

The PAYE estimate includes the selected age rebate and capped employee UIF, but excludes other payroll deductions. The retirement tool uses a separate qualifying deduction base and illustrates a ceiling, not an automatic refund. Check the employer contribution and deduction base before comparing retirement scenarios.

Reproduce this fictional profile: Current balance: R 10 000; Monthly contribution: R 300; Monthly employer retirement contribution: R 200; Annual qualifying deduction base (see scope): R 360 000; Assumed annual return (nominal): 5%; Years: 20.

• Projected balance: R 232 643,24
• Opening balance + credited contributions: R 130 000,00
• Modelled growth: R 102 643,24

Open Retirement annuity calculator. Retirement-annuity/fund accumulation with monthly employee and employer contributions and an assumed return after fees. The first-year indicative deduction ceiling is the smallest of contributions, 27.5% of the qualifying income base you enter, and R430,000 under the 2026/27 SARS guide. Confirm the qualifying base using the remuneration/taxable-income rules; the additional taxable-income limitation, carry-forward and lump-sum exclusions are not calculated. No tax refund is added to the fund. Two-pot allocation, savings-component withdrawals, preservation transfers, retirement income, tax on withdrawals and State grants are excluded. Contributions and rules remain constant.

UAE: Have you separated basic salary from allowances?

The gratuity calculation uses basic salary, with total contractual wage entered separately for its cap. Those inputs are not interchangeable. Use qualifying service excluding unpaid absence; the federal traditional full-time foreign-worker model does not cover every employment regime or alternative savings scheme.

Reproduce this fictional profile: Monthly basic salary (no allowances): AED 10,000; Monthly total contractual wage for two-year cap: AED 10,000; Qualifying continuous service (years, excluding unpaid absence): 5.

• Estimated end-of-service gratuity: AED 35,000.00
• Monthly basic salary: AED 10,000.00
• Gratuity days before cap: 105.00

Open End-of-service gratuity calculator. Traditional end-of-service gratuity for a full-time foreign worker covered by UAE federal private-sector labour rules, not a citizen pension. Requires at least one year of qualifying continuous service. Gratuity uses the final basic wage / 30: 21 days per year for the first five years and 30 days per year thereafter, with proportional fractions after qualifying. Enter service excluding unpaid absences. The two-year wage cap uses the total contractual monthly wage entered; it must be at least the basic wage. The same final basic wage is applied to all service. Nationals, domestic workers, DIFC/ADGM rules, part-time employment, alternative end-of-service savings schemes, disputes, deductions, leave pay and other final settlement items are excluded. Confirm applicable terms with the relevant authority; this is not a legal determination.

Malaysia: Are you using chargeable income and regular EPF wages correctly?

The income-tax tool uses chargeable income after reliefs for its supported assessment year. EPF instead uses regular monthly wages within its supported age and wage range. Official contribution bands can produce a step change at a wage boundary, so multiplying salary by a percentage can disagree with the displayed contribution.

Reproduce this fictional profile: Current balance: RM 10,000; Regular monthly EPF wages (no bonus): RM 5,000; Age at start: 35; Assumed annual dividend return (not guaranteed): 5%; Years: 20.

• Projected balance: RM 520,366.81
• Opening balance + credited contributions: RM 298,000.00
• Modelled growth: RM 222,366.81

Open EPF / KWSP calculator. EPF/KWSP accumulation for Malaysian citizens under 60, using regular wages without bonuses. Uses Third Schedule Part A effective October 2025: no contribution for wages up to RM10, RM20 wage bands through RM5,000 with employee 11% and employer 13% rounded up to ringgit, then RM100 bands through RM20,000 with employee 11% and employer 12%. Wages above RM20,000 are deliberately outside the input range; bonus exceptions, foreigners and PR categories are excluded. The projection ends by age 60. Salary and contribution rules remain constant. Returns are an assumed monthly-compounding illustration, not the official annual EPF dividend calculation or a guaranteed dividend. Account allocation, withdrawals, tax relief and post-60 contributions are excluded.

Netherlands: Is the result a full tax bill or only the supported component?

Box 1 includes the stated national-insurance treatment before credits; it does not calculate every part of a Dutch return. Lijfrente accumulation requires verified eligible contribution room, which the tool does not derive from salary. A higher projected balance does not prove a larger deductible contribution is permitted.

Reproduce this fictional profile: Current balance: € 10.000; Monthly contribution: € 300; Verified annual eligible contribution room (assumed each year): € 5.000; Assumed annual return (nominal): 5%; Years: 20.

• Projected balance: € 150.436,50
• Opening balance + credited contributions: € 82.000,00
• Modelled growth: € 68.436,50

Open Lijfrente calculator. Private lijfrente accumulation using monthly contributions within annual eligible room you have verified using the official jaarruimte/reserveringsruimte tool. That same room is assumed available each projected year; it is not calculated from salary alone and may change. Contributions above entered room suppress the projection. Return is an assumption after fees before payout taxes. No deduction refund is reinvested. AOW entitlement, occupational pension accrual, annuity payout pricing, tax at payout and eligibility for special products are excluded.

Spain: Have you accounted for the regional part of IRPF?

The tax page calculates the common-regime state component only. It cannot establish total Spanish income tax or take-home pay because regional tax and personal/family minimum treatment are excluded. The pension page covers the general individual-plan limit, not every employer or self-employed arrangement.

Reproduce this fictional profile: Current balance: 10.000 €; Monthly contribution: 100 €; Annual net employment / business income: 40.000 €; Assumed annual return (nominal): 5%; Years: 20.

• Projected balance: 68.229,77 €
• Opening balance + credited contributions: 34.000,00 €
• Modelled growth: 34.229,77 €

Open Individual pension plan calculator. Individual pension-plan accumulation under the general common-regime limit, without employer or self-employed enhanced allowances. Annual contributions must not exceed the lower of EUR 1,500 and 30% of entered net employment/business income. Excess scenarios suppress the projection. Monthly contributions are credited at month end; return is assumed after fees before withdrawal tax. Future limits and income are held constant. Tax refund reinvestment, regional/foral exceptions, carry-forward, State pension entitlement and payout taxation are excluded.

Brazil: Are you comparing annual assessment with monthly withholding?

The IRPF tool uses the supported annual simplified-deduction model rather than monthly IRRF. PGBL deduction eligibility is a separate choice involving the legal-deductions route and official pension contributions. Do not subtract the PGBL ceiling from the simplified-model result and treat that as a complete tax return.

Reproduce this fictional profile: Current balance: R$ 10.000; Monthly contribution: R$ 300; Annual gross taxable income for PGBL limit: R$ 60.000; Eligible for PGBL deduction using legal deductions and official pension contributions?: No / unsure — no deduction assumed; Assumed annual return (nominal): 5%; Years: 20.

• Projected balance: R$ 150.436,50
• Opening balance + credited contributions: R$ 82.000,00
• Modelled growth: R$ 68.436,50

Open PGBL calculator. Private PGBL accumulation, not an INSS benefit estimate. Monthly contributions compound at an assumed return after fees, before withdrawal tax. First-year potentially deductible contributions are shown only if you confirm eligibility for the legal-deductions declaration and required official-pension contributions; then they are limited to 12% of entered annual gross taxable income. Eligibility is not established by the calculator, and no refund is reinvested. All contributions are invested even when not deductible. VGBL taxation, INSS entitlement, regressive/progressive payout tax, benefit pricing and future tax-rule changes are excluded. The separate Brazil tax calculator uses the simplified deduction and does not combine this PGBL deduction.
