Easiest Way to Calculate Fixed Deposit Interest Rates

When you invest in a fixed deposit or a term deposit, the first thing you want to know is the interest rate. You can get the term deposit interest rates on the official website of the issuer or through an in-person visit at the branch of the issuer. Similarly, you can find the post office FD rates on the official website of the Indian Postal service. In most cases, you will get a chart depicting two variables – tenor and interest rate. But, this chart doesn’t give the complete picture of how exactly the interest rate is calculated on the FD.

You can, of course, use the following mathematical formula of FD calculation:



  • A is maturity amount
  • P is the principal amount
  • r is the rate of interest
  • n is compounded interest frequency
  • t is number of years (tenure)

So, if you want to invest Rs. 1.5 lakhs at 6% for 7 years with annual interest payout, it is manually calculated as:

150000(1+6/1)^1*7=Rs. 227,466

You must have understood how complex and time-consuming this is. Just imagine how more cumbersome it will be to calculate periodic interest payouts!

An online FD calculator can do this for you automatically. It is the most convenient and quickest way to calculate term deposit interest rates. It is also a highly reliable tool to get clear visibility of interest calculation and FD savings growth during the entire tenor.
