How fixed deposit returns work
A fixed deposit pays a guaranteed interest rate for a fixed tenure. Most banks compound interest quarterly, so the maturity amount is principal × (1 + r/n)^(n×t), where r is the annual rate, n the number of compounding periods per year and t the tenure in years. More frequent compounding gives a slightly higher maturity value.
FDs are low-risk and predictable, which makes them popular for capital preservation and short-to-medium goals. The trade-off is that returns often barely beat inflation, so they suit safety more than growth.
Frequently Asked Questions
▸How is FD maturity calculated?
Using compound interest: maturity = principal × (1 + rate/n)^(n × years), where n is the compounding frequency. Most banks compound quarterly (n = 4).
▸Is FD interest taxable?
Yes — FD interest is added to your income and taxed at your slab rate. Banks deduct TDS if interest crosses the annual threshold.
