Compound Interest Calculator
See how your money grows when interest is added to the principal at regular intervals.
Compound interest grows faster than simple interest because each period's interest is added back to the principal before the next period's interest is calculated. Lilu Baba's Compound Interest Calculator lets you choose the compounding frequency and instantly see how much difference it makes.

Use whatever frequency your bank or investment actually compounds at — this is usually stated in your account or product terms (commonly quarterly for Indian fixed deposits).
With more frequent compounding, interest is added to the principal more often, so subsequent interest is calculated on a slightly larger base each time — small effect per period, but it adds up over time.
