A PPF calculator estimates the maturity value and interest on a Public Provident Fund account from your yearly contribution, the investment period, and the interest rate. It opens with 7.1% a year, the rate notified for July–September 2026, and the result is an estimate based on that configured rate and an annual-compounding methodology.

Smart Insights
Generated from the numbers you entered — no guesswork.
- Investing ₹1,50,000 a year for 15 years builds an estimated ₹40,68,209.
- Interest of ₹18,18,209 is about 44.7% of the maturity value — a calculated growth of 80.8% on what you put in.
- The last year alone adds roughly ₹2,69,695 of interest, because compounding works on the largest balance.
- Contributions are capped at ₹1,50,000 per financial year, so the maturity value cannot be raised by investing more than the limit.
- This is a mathematical estimate at a fixed rate. Actual PPF interest is credited annually on a monthly minimum balance and the rate is reviewed by the government every quarter.
How does the PPF Calculator work?
Each step the calculator runs, in plain language.
- 1
What PPF is
The Public Provident Fund is a government-backed long-term savings scheme with a 15-year term. Contributions qualify for deduction under section 80C in the old tax regime, and the interest and maturity value are exempt from tax under current rules.
- 2
How PPF interest is calculated
Interest accrues monthly on the lowest balance between the 5th and the last day of the month, and is credited to the account once a year at the end of the financial year. Because credited interest itself earns interest in later years, the balance compounds annually.
- 3
Contribution rules
You must deposit at least ₹500 in a financial year to keep the account active, and no more than ₹1,50,000 across all PPF accounts in your name. Deposits above the ceiling do not earn interest.
- 4
Lock-in, withdrawals, and extension
The account matures after 15 full financial years. Partial withdrawal is allowed from the seventh year and a loan from the third, subject to limits. At maturity you can withdraw fully or extend in 5-year blocks, with or without fresh contributions.
PPF Calculator formula
The exact maths behind every number on this page.
M = Σ P × (1 + r)^(N − k + 1) • balanceₖ = (balanceₖ₋₁ + P) × (1 + r)
- M
- Maturity value at the end of the investment period
- P
- Contribution made each year
- r
- Annual interest rate as a decimal (7.1% → 0.071)
- N
- Number of years contributions continue
- k
- Year in which a particular contribution is made
This calculator assumes one contribution at the start of each year and interest compounded once a year. A real PPF account credits interest annually on the lowest balance between the 5th and the last day of each month, so contributions made later in the year, or spread monthly, can earn slightly less than shown.
PPF Calculator calculation example
₹1,50,000 invested at the start of every year for 15 years at 7.1% a year.
- 1Yearly investment (P)₹1,50,000
- 2Rate (r)7.1 ÷ 100 = 0.071
- 3Period (N)15 years
- 4Year 1 balance1,50,000 × 1.071 = ₹1,60,650
- 5Total invested1,50,000 × 15 = ₹22,50,000
- 6Maturity value (M)₹40,68,209 (approx.)
The account is estimated to mature at about ₹40,68,209, of which roughly ₹18,18,209 is interest — around 45% of the final balance, entirely from compounding.
Important assumptions
What this calculation includes, and what it leaves out.
- The rate field defaults to 7.1% a year, the rate notified for July–September 2026 (last verified 2026-08-22). Small-savings rates are reviewed every quarter, so the rate is not permanent — edit the field if a new rate has been notified.
- One contribution is assumed at the start of each financial year, and interest is compounded once a year. A real account credits interest on the lowest balance between the 5th and the last day of each month, so mid-month deposits earn slightly less.
- The base term is 15 full financial years; longer periods model extension in 5-year blocks with fresh contributions.
- Contributions are capped at ₹1,50,000 a financial year across all PPF accounts in your name; amounts above that earn no interest.
- The projection holds one rate for the entire period, so the actual maturity value will differ whenever the notified rate changes.

Benefits
Why people use this calculator before signing a loan.
Sovereign-backed safety
The scheme is backed by the Government of India, so there is no credit risk on the balance.
Tax-efficient compounding
Under current rules contributions, interest, and maturity proceeds all receive favourable tax treatment, which lifts the effective return versus a taxable deposit.
Disciplined long-term saving
The 15-year lock-in makes PPF useful for goals such as retirement or a child's education.
Assumptions to keep in mind
The estimate holds the rate constant for the whole period, but the government reviews it quarterly, so actual maturity value will differ if the rate changes.
Financial tips
Practical guidance to act on your result.
- Invest before the 5th of April to earn a full year of interest on the whole contribution.
- If you invest monthly, deposit before the 5th of each month — interest is calculated on the lowest balance between the 5th and month-end.
- PPF suits the debt part of a long-term portfolio; equity products carry more risk but are not rate-capped.
- Extend the account in 5-year blocks at maturity if you do not need the money — the balance keeps compounding tax-free.
