How to Calculate Fixed Deposit Interest?

If you want to gain more from your investment, you should know how interest on FDs is calculated. There are two methods of calculating interest on a fixed deposit, and they are:

  1. Simple Interest Method

    Under this method, you multiply the principal amount, interest rate and tenure to get the result. The formula is:

    Simple Interest (SI) = P (Principal amount) x R (Rate of interest) x T (Tenure) divided by 100 or P x R x T/100

    For instance, if you invest Rs 10,000 @ 6% p.a. for 5 years, you get:

    10,000 x 6 x 5/100 = Rs 3000

    You will earn Rs 3000 in 5 years.

  2. Compound Interest Method

    The compounding method enables you to earn interest on interest, and most banks offer compound interest to attract FDs. For example, if you invest Rs 10,000 @ 6% p.a. for 5 years compounded quarterly, you will get Rs. 13,469* on maturity.

    To arrive at the calculation, you can use this formula

    Compound Interest (CI) = P {(1 + i/100n) ^nt – 1}, where P= Principal, i= rate of interest, t= time, n= no. of time interest compounded annually.

    Compound Interest (CI) = 10000 {(1 + 6/100*5)^5*4 – 1} = Rs 3,469*

    On maturity, you will get 13,469* rs.

    *These are indicative numbers and may differ basis the actual number of days considered for calculation
