How to Calculate Compound Interest on IOB Recurring Deposit?

Interest on a recurring deposit account with IOB is compounded every quarter. Meaning, deposit holders will earn interest every 3rd month from the time of deposit and 4 times in a year.

Individuals holding an RD account can use the IOB RD interest rates calculator to determine their returns. The formula used by this calculator is mentioned below –

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


  • M is the maturity amount.
  • n is the number of quarters within the deposit period.
  • R is the amount deposited in the RD.
  • i is the rate of interest divided by 400 (owing to 4 quarters).

Consider the following example to understand the formula better:

Mr. Amol is aged 54 and resides in Guwahati. He opens an RD account with IOB and deposits Rs.5,000 every month for 4 years. As per the table illustrated above, he will earn a rate of interest of 6.80%.


  • n = 16 (4 years x 4).
  • R = Rs.5,000.
  • i = 0.017 (6.80 / 400).

Now, when placed in the formula –

M = 5,000 x {(1 + 16) x 16 – 1} / 1- (1 + 0.017) (-1/3)

Hence, M = Rs.276,418.

So, Mr. Amol will receive Rs.2,76,418 when he invests Rs.5,000 every month for 4 years at a rate of interest of 6.80%.

If Mr. Amol was a senior citizen, his maturity amount would have been Rs.2,79,431 as per an applicable rate of interest of 7.30%.

As manual calculations can be subject to errors and can be time-consuming, individuals can use an IOB Recurring Deposit calculator to know their RD maturity amount.

Various Factors that Affect IOB RD Interest Earnings

Some of the factors that influence the rate of interest on an IOB RD are –

  • Deposit tenure 

The primary factor that affects RD interest rates is the deposit tenure or maturity period. Longer periods invite higher rates and vice versa. From the table listed above, the rate for depositing for 1 year to 1 year 364 days is 6.60% while that of 3 years to 10 years is 6.80%.

  • Age of the depositor 

The second factor that impacts the rates of interest is the depositor’s age. Senior citizens will earn 0.5% additional interest compared to other customers.

  • Reverse repo rate

The last factor is the reverse repo rate, one of the instruments of monetary policies of the Reserve Bank of India (RBI). The RBI borrows money from the commercial banks (like IOB) and pays them interest as per the reverse repo rate. If this rate is high, banks will earn more interest on the deposits and, in turn, increase the rate of interest on their term deposits (like recurring deposits).
