## Frequently asked questions

### How does ₹50,00,000 at 10% CI grow to over ₹3.6 crore in 20 years?

At 10% quarterly compounding, the effective annual rate is 10.38%. Over 20 years, ₹50,00,000 grows to about ₹3,60,47,350, over 7x the original investment. The Rule of 72 at 10.38% gives a doubling period of about 6.9 years, so ₹50 lakh approximately triples after 3 doublings (20.7 years).

### What if the interest rate is 8% instead of 10% for ₹50 lakh over 20 years?

At 8% quarterly compounding for 20 years, ₹50,00,000 grows to about ₹2,44,55,000 vs ₹3,60,47,350 at 10%. The 2-percentage-point difference over 20 years costs about ₹1.16 crore, nearly 2.3x the original investment. For large lumpsum investors, even small differences in rate matter enormously over long horizons.

### How should I handle ₹3.6 crore in compound interest proceeds at maturity?

CI/FD proceeds are fully taxable as income at maturity (or when credited). For a ₹3.6 crore corpus, plan the redemption carefully: consider splitting into multiple FDs maturing in different financial years to spread the tax incidence. A tax advisor can also help with capital deployment into tax-efficient instruments like debt mutual funds or hybrid funds for the next investment cycle.
