Work out what investing could earn you: with inflation, costs and Dutch tax, and a range for good and bad market years.
Before costs and tax. This is an assumption, not a forecast: past returns say nothing certain about the future.
How much the value moves up and down (standard deviation). We use it to calculate the range. Equity funds usually fluctuate more than bond funds.
The European Central Bank aims for 2% inflation over the medium term.
In 30 years you can expect to have
€203,259
That is €112,214 in today's euros.
After selling and €59,395 tax. If you don't sell, your investments are worth €262,655.

Costs also eat into your return: without costs you would have had €6,974 more at the end.
Final amount in today's euros, compared with your calculation
With this final amount you can then withdraw about €532 per month for 25 years, in today's euros. In 2056 that is €963 per month; after that the amount rises with inflation.
With the same return, costs and tax. With tax on sale, we assume you sell everything at the end of the build-up.
Tax on sale at the end: €59,395 (not in the table).
In 2026 you pay box 3 tax on a deemed return: 6.00% for investments, on wealth above €59,357 per person (€118,714 with a tax partner). The rate is 36%. If your actual return is lower, you may report that lower return.
For 2027 the cabinet proposes an allowance of €30,846 per person and a deemed return of 7.87% for investments.
A new system starts in 2028. In February 2026 the House of Representatives passed a bill that taxes actual value growth every year. On 29 September 2026 the cabinet announced it wants to tax investments only when you sell, with €1,000 per person per year exempt. The Senate still has to approve this.
In the calculator you choose which rules to apply. Amounts after 2026 are proposals and may still change. We assume a fund that reinvests dividends; Dutch residents can usually offset dividend tax, so we leave it out.
This is an example calculation, not investment advice. The outcome depends entirely on the assumptions you choose.
Investing involves risk. The value of your investments can fall and you can lose (part of) your money. Past returns are no guarantee of future results.
Tax rules change and depend on your personal situation. Check the Dutch Tax Administration (Belastingdienst) website for your situation. We don't store your input; you can share a calculation via the link.
