Calculate Public Provident Fund maturity value with annual deposits, current interest rates, and 15-year term projections with extensions.
The Public Provident Fund matures at 15 years, and this calculator projects what that pays out: it compounds an annual deposit at the interest rate the Government of India currently notifies, for the full term and into the 5-year extension blocks the scheme allows. Most people misjudge timing, not the rate. Interest accrues on the lowest balance between the 5th and last day of each month, so a deposit after the 5th earns nothing that month; twelve monthly installments of Rs 12,500 earn less than one Rs 1,50,000 deposit before 5 April. The rate is a projection, not a promise - the government resets it quarterly.
A concrete input and expected output from the current implementation.
Input
Annual deposit: Rs 1,50,000, paid on or before 5 April each year; interest rate: 7.1% p.a.; term: 15 years.
Expected output
Maturity value after 15 years: Rs 40,68,209. Total deposited: Rs 22,50,000. Total interest earned: Rs 18,18,209.
Each deposit earns a full year's interest, and interest is credited annually and compounds from the next year. Summing 15 start-of-year deposits at 7.1% gives Rs 4,068,209, of which interest is Rs 1,818,209 - about 45% of the final corpus.
The scheme pays interest on the lowest balance between the 5th and the last day of each month, credits it at the end of the financial year, and compounds it from the next year. The calculator projects 15 yearly rows - deposit, interest, closing balance - assuming each deposit lands before the 5th, the pattern that earns maximum interest.
The term runs 15 financial years from the year the account opens, after which the entire balance is payable. The tool also projects extensions in 5-year blocks, with continued deposits or with none; a balance left in an extended account keeps earning interest. Both projections answer one question: what does going past maturity add?
Yes, under the scheme's long-standing treatment: deposits qualify for deduction under Section 80C within the overall Rs 1.5 lakh cap, and both the interest credited each year and the maturity proceeds are exempt from income tax. The deduction applies only under the old tax regime. Tax law can change, so confirm the treatment for the current assessment year.
You can withdraw the entire balance at any time after maturity, or extend the account in 5-year blocks - with continued deposits, which keeps the 80C deduction, or without them, in which case the balance keeps earning at the notified rate. There is no deadline; leaving the account untouched after maturity is allowed, and partial withdrawals are limited to once a year.
