Inflation Calculator for Netherlands

Method and scope

Future cost = current cost × (1 + annual inflation)^years. Purchasing power = current amount / (1 + annual inflation)^years. Inflation is a user assumption held constant; no live national inflation rate is fetched.

Using this calculator in Netherlands

The inflation rate is entered by you and stays constant. No current Netherlands CPI series is loaded. Both results use EUR: future cost describes a future price, while purchasing power describes what today's amount could buy after the entered period.

Try the starting example

Amount today: € 10.000; Assumed annual inflation: 3%; Years: 20.

Future cost of the same purchase: € 18.061,11.

Compare one assumption at a time

Compare future cost and remaining purchasing power together. A higher inflation assumption raises the future cost of the same basket and reduces the purchasing power of a fixed amount. This is a scenario comparison, not a current national CPI reading. These fictional scenarios use the starting inputs printed above, not your current entries in the interactive calculator.

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.

To reproduce the table, reset the calculator, change only the named input and compare the result and any warning. Record the assumptions with your result. See worked planning examples and our calculation and correction process.
