What is a Fixed Deposit (FD)?
A Fixed Deposit (FD) is one of the safest investment options offered by banks and NBFCs in India. You deposit a lump sum for a fixed tenure — from 7 days to 10 years — at a guaranteed interest rate. Unlike mutual funds or stocks, FD returns are not linked to the market, making them ideal for risk-averse investors who want capital protection and predictable growth.

FD Maturity Amount Formula
Banks in India use the Compound Interest formula to calculate FD maturity amount for tenures above 6 months. For tenures under 6 months, Simple Interest is applied. Finzony's FD calculator uses the standard quarterly compounding method followed by most Indian banks.
Compound Interest Formula (Standard Bank Method):
- A= P × (1 + r/n)^(n × t)
- A= Maturity Amount (what you receive at end of tenure)
- P= Principal Investment (amount deposited)
- r= Annual Rate of Interest in decimal (e.g., 6.5% = 0.065)
- n= Compounding frequency per year (4 = Quarterly, 12 = Monthly)
- t= Tenure in years
FD Maturity Calculation Example
Principal: ₹1,00,000 | Rate: 6.5% p.a. | Tenure: 5 years | Compounding: Quarterly (n=4)
Step 1: r/n = 0.065 ÷ 4 = 0.01625
Step 2: n×t = 4 × 5 = 20 periods
Step 3: A = 1,00,000 × (1 + 0.01625)^20
Step 4: A = 1,00,000 × 1.38047
FD Maturity Amount = ₹1,38,047 | Total Interest Earned = ₹38,047
