Compound Interest Calculator
See how principal grows when interest is reinvested over time.
How this estimate works
Compounding earns returns on principal and accumulated interest. Product charges, tax and inflation are not automatically deducted.
Check your inputs & compare scenarios
Replace the examples with your current figures. Keep the currency and time period consistent with each field. Save one scenario, then change an amount or rate to compare the effect. Reopened scenarios calculate with current rules; your original result stays in history.
