Those holding a National Savings Recurring Deposit Account can use a post office RD calculator 2020 to assess their maturity amount.

The formula used to calculate returns on a recurring deposit is –

M = R x {(1 + n) x n – 1} / 1- (1 + i) (-1/3)

In the above formula –

  • R is the amount deposited per month.
  • n is the number of quarters in the tenure.
  • i is the rate of interest divided by 400 (for 4 quarters in a year).
  • M is the maturity amount.

The following example can explain the above formula better – 

Mrs. Banerjee lives in Kolkata and opens a National Savings Recurring Deposit Account with a monthly deposit of Rs.7,000 for 5 years at the prevailing rate of interest of 5.8%.

Here,

  • R = Rs.7,000.
  • i = 0.0145 (5.8 / 400).
  • n = 20 (5 years x 4).

When the figures are placed in the formula –

M = 7,000 x {(1 + 20) x 16 – 1} / 1- (1 + 0.0145) (-1/3)

Therefore, M = Rs.4,88,237.

Hence, Mrs. Banerjee earns Rs.4,88,237 by depositing Rs.7,000 every month for 5 years at a 5.8% rate of interest.

Individuals can use a postal RD calculator to make such assessments easily. Manually calculating the maturity amount with the above formula can be time-consuming and subsequently lead to inaccuracies.
