Retirement Savings Calculator
Worked example (the default inputs above): Age 35 to 65 (30 years), €20,000 saved, €300 a month, 5% a year → projected pot about €337,578 (about €186,367 in today's money at 2% inflation), on €128,000 paid in.
Key fact: For expats, the biggest retirement risk is not the market — it is fragmented pensions: years of contributions scattered across countries, each with its own rules and retirement age.
What this calculator does
This calculator projects what your retirement pot could be when you stop working, from your current age, retirement age, savings so far, monthly contributions and an assumed annual return. It also shows the pot in today's money, so inflation does not flatter the number.

How to use it
- Enter your current age and your planned retirement age.
- Enter what you have already saved and what you can add every month.
- Enter an expected annual return, then read your projected pot — and its value in today's money — instantly.
The formula
Each year: balance = (balance + 12 × monthly contribution) × (1 + return). Repeated from now until retirement age, this is compound growth. Today's-money value = projected pot ÷ (1.02)years, using 2% annual inflation as an illustration. Example: €20,000 saved at 35, €300 a month at 5% for 30 years → about €337,578 nominal, about €186,367 in today's money.

Worked example with real numbers
A 35-year-old in the Netherlands has €20,000 saved and adds €300 a month. At an assumed 5% a year, the pot reaches about €337,578 by 65 — on €128,000 paid in, so roughly €209,578 is growth. In today's money at 2% inflation that is about €186,367, which is the number to compare with your spending plans, not €325,618. Starting at 45 instead of 35, with the same €300 a month, the pot reaches only about €178,055 — ten lost years cost nearly half the pot, because the last decade's growth builds on everything saved before it.

Method: annual compounding of savings plus monthly contributions at the return you assume. The return is an assumption, not a guarantee — real returns vary and can be negative. Inflation is illustrated at 2% a year. State pensions, employer pensions, tax relief and tax on withdrawals all vary by country and are NOT included here: EU state pensions generally require minimum contribution years in each country, and cross-border aggregation rules (EU Regulation 883/2004) can combine periods across member states. Check your national pension body and a qualified adviser for your record.
