FD maturity amount formula:

You may avail of two types of FD – simple interest FD and compound interest FD. We provided two calculators for both kinds of FD

The formula for the FD calculator for simple interest

M = P + [P x r x t/100]

  • P: the principal amount that you deposit
  • r:rate of interest per annum
  • t: tenure in years


If we deposit a sum of Rs 100000 for five years at an interest rate of 10%

M = Rs 100000 + (100000 x 10 x 5/100)

M = Rs 1,50,000

Compound interest FD:

The formula for the fixed Deposit return calculator uses the

M= P + P [(1 + i/100) t – 1]

  • P: principal amount
  • r:rate of interest per particular period
  • t:tenure


if you take the same variables, the FD compound interest will get,

M= Rs 1,00,000 {(1 + 10/100) 5-1}

M = Rs 1,61,051
