Recurring Deposit – How is interest and maturity amount calculated?

Let us have a look at the compound interest calculation first.

A formula for calculating annual compound interest is

A = P \left(1 + \frac{r}{n}\right)^{nt}


  • A = final amount
  • P = principal amount (initial investment)
  • r = annual nominal interest rate (as a decimal, not in percentage)
  • n = number of times the interest is compounded per year
  • t = number of years

Recurring deposit or RD is paid monthly but it is compounded quarterly. So in order to find the total maturity value in RD, we should calculate the final value for each installment separately and then add them all to get the final result.

Special Formula for Quarterly compounding Recurring Deposit maturity value calculation

Alternatively, you can use a special formula to calculate the RD maturity value in a single step.

M = ( R x [(1+r)n – 1 ] ) / (1-(1+r)-1/3)
Where, M = Maturity value,R = Monthly Installment, r = Rate of Interest (i) / 400 and n = Number of Quarters.

Although this formula seems to be complex you can easily calculate the maturity value of your recurring deposit for any tenure and interest rates using the Online – RD Calculator provided at the top of this page.
