Tenure (years) *

PPF has a minimum 15-year lock-in, extendable in blocks of 5 years.

How to read your result

The maturity amount is what the account would hold at the end of the tenure if the current rate never changed. Treat it as a planning estimate, not a guaranteed figure: the rate is set by the government every quarter. Total interest earned shows how much of that amount comes from compounding rather than your own deposits.

AI explanation

Formula

FV = A × (((1+r)^n − 1) / r) × (1+r), where r = annual PPF rate, n = years, A = annual investment

Worked examples

₹1,50,000/year for 15 years

Worked example: ₹1,50,000/year for 15 years
Field	Value
Annual investment	₹1,50,000
Tenure (years)	15
Maturity amount	₹40,68,209.22
Total amount invested	₹22,50,000
Total interest earned	₹18,18,209.22

Rate r = 7.1% = 0.071, so the yearly growth multiplier is 1 + r = 1.071.
Over n = 15 years, 1.071^15 = 2.797964.
Annuity-due factor = ((1.071^15 − 1) ÷ 0.071) × 1.071 = 27.121395.
Maturity amount = ₹1,50,000 × 27.121395 = ₹40,68,209.22.
Interest earned = ₹40,68,209.22 − ₹22,50,000 invested = ₹18,18,209.22.

Depositing the maximum every year for the minimum 15-year term, interest makes up about 45% of the maturity amount — at a constant 7.1%, which the government can revise each quarter.

₹60,000/year (₹5,000 a month, paid yearly) for 15 years

Worked example: ₹60,000/year (₹5,000 a month, paid yearly) for 15 years
Field	Value
Annual investment	₹60,000
Tenure (years)	15
Maturity amount	₹16,27,283.69
Total amount invested	₹9,00,000
Total interest earned	₹7,27,283.69

The annuity-due factor for 15 years at 7.1% is the same 27.121395 as above — it depends only on the rate and the term.
Maturity amount = ₹60,000 × 27.121395 = ₹16,27,283.69.
Interest earned = ₹16,27,283.69 − ₹9,00,000 invested = ₹7,27,283.69.

The maturity amount scales in direct proportion to the yearly deposit: 40% of the maximum deposit gives 40% of the maximum-deposit maturity amount.

₹1,50,000/year, extended by one 5-year block to 20 years

Worked example: ₹1,50,000/year, extended by one 5-year block to 20 years
Field	Value
Annual investment	₹1,50,000
Tenure (years)	20
Maturity amount	₹66,58,288.17
Total amount invested	₹30,00,000
Total interest earned	₹36,58,288.17

Over n = 20 years, 1.071^20 = 3.942661.
Annuity-due factor = ((1.071^20 − 1) ÷ 0.071) × 1.071 = 44.388588.
Maturity amount = ₹1,50,000 × 44.388588 = ₹66,58,288.17.
Interest earned = ₹66,58,288.17 − ₹30,00,000 invested = ₹36,58,288.17.

Five more years of deposits add ₹7,50,000 of contributions but ₹18,40,078.95 of extra interest compared with stopping at 15 years, because the accumulated balance keeps compounding.

Assumptions and limitations

This calculator assumes

Assumes the full annual investment is made at the start of each PPF year — real PPF interest is computed monthly on the lowest balance between the 5th and last day of the month, so depositing early in April specifically can earn slightly more than this model assumes.
Uses the PPF interest rate for the Jul-Sep 2026 quarter (7.1% p.a.), which the Ministry of Finance reviews and can revise every quarter.
Assumes that rate stays the same for every year of the projection.
PPF interest earned and maturity proceeds are currently tax-exempt (EEE status) under prevailing rules.

What it does not account for

Does not model rate changes — if the government revises the PPF rate in a later quarter, the real maturity amount will differ from this projection.
Does not model monthly or irregular deposits, partial withdrawals, or loans against the PPF account.
Deposits made after the 5th of a month earn no interest for that month in a real PPF account; this calculator assumes every deposit earns interest for the full year.

When to use this calculator

Estimating what maximum yearly PPF deposits could grow to by a target year, such as a child's college admission or retirement.
Deciding whether to extend a matured PPF account by another 5-year block.
Comparing the tax-free PPF projection with other long-term savings options.

Frequently asked questions

What is the current PPF interest rate?

7.1% per annum for the July-September 2026 quarter, unchanged since April 2020. The Ministry of Finance reviews and can revise this rate every quarter.

Can I extend my PPF account after 15 years?

Yes — PPF can be extended indefinitely in blocks of 5 years, with or without making further contributions, once the initial 15-year term is complete.

Is PPF interest taxable?

No — PPF currently enjoys "EEE" (Exempt-Exempt-Exempt) tax status: contributions, interest earned, and maturity proceeds are all tax-exempt under prevailing rules.
