How much will it be worth in 10 / 20 / 30 years?

Enter a starting amount, an annual return and/or inflation. You’ll get values for 10, 20 and 30 years, plus a detailed table and a simple chart. Everything runs locally.

Choose what you want to estimate: Nominal value (with returns) and/or real value (adjusted for inflation).

Example: 10000 = $10,000 (or €10,000)
Optional. Use 0 if you want inflation-only.
Optional. Used to compute “real” value.
Real value = nominal / (1+inflation)^years
€ / $ / £ … just a display symbol.
Formatting only (not calculations).

How it works: nominal value uses compound growth: value = principal × (1 + return)^years. Real value discounts inflation: real = nominal ÷ (1 + inflation)^years.

This tool is useful for quick intuition: savings goals, long-term budgets, and comparing “today’s money” vs “future money”.
