A Fixed Deposit (FD) is a financial instrument offered by banks and NBFCs where you deposit a lump sum for a fixed tenure at a predetermined interest rate. Unlike savings accounts, the rate is locked in and guaranteed regardless of market conditions.
Indian banks compound FD interest quarterly by default, meaning your interest is reinvested every 3 months. This is why the effective annual yield (EAR) is slightly higher than the nominal rate quoted.
Step 1 — Enter your principal deposit amount
Step 2 — Set your bank's interest rate (check their website)
Step 3 — Choose tenure in years (1–10)
Step 4 — Select compounding frequency (quarterly for most Indian banks)
Step 5 — See maturity value, effective yield, and year-wise growth
