How much will your ₹5 lakh FD grow in 10 years? What does a monthly SIP of ₹10,000 become at 12% returns? Compound interest — earning interest on interest — is the engine behind savings accounts, mutual fund SIPs, and PPF in India. Pitara's free compound interest calculator projects future value with optional recurring contributions, in your browser.

Understanding compounding frequency
More frequent compounding grows faster at the same annual rate — monthly beats yearly. Bank FDs often compound quarterly; savings accounts may compound daily. When comparing products, match compounding frequency before deciding. Small rate differences compound dramatically over 15–20 year horizons.
