What does a €100,000 retirement savings pot grow to over 20 years?
Based on these numbers, your €100,000 grows to about €329,066 — €229,066 in compound interest earned along the way.
How this grows over time
What is compound interest?
Compound interest means the interest you earn also starts earning its own interest, instead of just being calculated on your original amount every time. Over long periods this makes a real difference compared to simple interest, where only the original amount ever earns interest.
This does not convert between currencies
Choosing a currency only changes how the result is displayed — the symbol and the digit grouping — it does not apply any exchange rate. Entering 10,000 with dollars selected shows "$10,000"; the same 10,000 with rupees selected shows "₹10,000." The underlying number is identical either way, since compound interest math doesn’t care what currency it’s denominated in — only what you actually invest and what rate you actually earn.
How compounding frequency changes the result
More frequent compounding — daily beats monthly, monthly beats annually — grows your money slightly faster at the exact same stated interest rate, since each bit of interest starts earning its own interest sooner. The difference is usually modest at typical rates, but it grows with a higher rate and a longer time period.
