PPF Calculator
Public Provident Fund maturity projection.
As of FY 2026-27Inputs
This calculator applies to India — the rules behind it are Indian tax/regulatory rules, not just the currency, so it isn't shown in other currencies.
This calculator is for general information only and isn't financial advice. Rates, tax rules, and your actual eligibility depend on your specific situation — check with your bank or a qualified advisor before acting on it.
Formula
Balance_y = (Balance_{y−1} + Deposit) × (1 + r)
Each year, the annual deposit is added to the running balance and the combined amount earns interest at rate r (set by the government, currently around 7.1%). Interest compounds once per year on the balance after the deposit — the standard PPF accrual method.
Worked example
Depositing the maximum ₹1,50,000 every year for 15 years at 7.1% yields a maturity of about ₹40.7 lakh against ₹22.5 lakh deposited — roughly ₹18.2 lakh in interest. The 15-year lock-in and EEE tax status (exempt contribution, growth, and withdrawal) are why PPF is a staple long-term savings vehicle in India.
Where this can give the wrong answer
- Minimum tenure is 15 years in this calculator (matching PPF account rules); extensions beyond 15 are allowed in real accounts but use the same projection logic with a longer years input up to 50.
- The annual deposit cap is ₹1,50,000 — amounts above that aren't permitted in a real PPF account even though the calculator would accept a higher number.
- Government-notified PPF rates change every quarter; the rate you enter is held constant for the full projection, so refresh when the Ministry of Finance announces a revision.
FAQ
- No — it projects the corpus only. The tax saving on contributions is separate and depends on your slab; the withdrawal remains tax-free regardless, which is the main long-term benefit.
