How to Calculate Fixed Deposit Returns

The maturity amount for a Fixed Deposit is calculated using the compound interest formula:

A = P × (1 + r/n)^(n×t)

Where:

  • A = Maturity amount
  • P = Principal amount (initial investment)
  • r = Annual interest rate (in decimal form)
  • n = Compounding frequency per year
  • t = Time period in years

Example Calculation

For an FD of ₹1,00,000 at 7% interest for 5 years with quarterly compounding:

  • P = 1,00,000
  • r = 7/100 = 0.07
  • n = 4 (quarterly compounding)
  • t = 5 years
  • A = 1,00,000 × (1 + 0.07/4)^(4×5) = ₹1,41,059
  • Interest earned = ₹41,059

Compounding Frequency Impact

Different compounding frequencies affect your returns:

  • Annually: Compounded once per year
  • Semi-annually: Compounded twice per year
  • Quarterly: Compounded four times per year
  • Monthly: Compounded twelve times per year
  • Daily: Compounded 365 times per year
  • Higher compounding frequency = higher returns

About Fixed Deposits

A Fixed Deposit (FD) is a financial instrument provided by banks and NBFCs that offers investors a higher rate of interest than a regular savings account. The money deposited in an FD remains locked in for a fixed period, ranging from a few days to several years.

  • Guaranteed returns
  • Higher interest rates than savings accounts

  • Loan facility against FD
  • Tax saving options available (Tax Saver FDs)
