How to calculate interest on PPF balance

The Public Provident Fund (PPF) is one of the most popular investment options. Not only does it offer tax-savings under section 80C of the Income Tax Act, but the interest earned on it and maturity amount are also exempt from tax.

The interest rate applicable on PPF investments is reviewed and announced by the government every quarter. For the quarter ending March 31, 2020, the interest rate offered is 7.9 per cent per annum (compounded yearly).

According to PPF rules, the interest is calculated on a monthly basis but it is credited into the account at the end of financial year on March 31. Interest becomes payable for that month if the deposit is made before the fifth of that month.

One can invest a minimum Rs 500 and maximum of Rs 1.5 lakh in a financial year. Here's how interest is calculated in case of lump-sum and monthly contributions.

• Monthly contributions

Suppose you are investing Rs 12,500 per month. Let us assume that the interest rate for PPF is 7.6 per cent and remains constant througout the financial year. Here's how your PPF interest will be calculated:


The total interest credited into your account is Rs 5,858.33 for that financial year. Had you been depositing your money into the PPF account on or before 5th of every month, then you would have earned Rs 316.67 more in the financial year.

• Lump-sum contribution

On the other hand, interest is calculated as follows in case you make a one-time lumpsum deposit during the fiscal:

If the date of deposit in case of lump-sum contribution had been after 5th of April, in that case, you would have not earned the interest for the month of April. The interest earned in that case would have been Rs 10,450.

Watch outs
PPF scheme rules 2019 have removed the restrictions on the maximum number of contributions that can be made in a single fiscal year. However, the maximum contribution in a fiscal year cannot exceed Rs 1.5 lakh.
