How to use this calculator: PPF Calculator

Public Provident Fund maturity over 15 years (extendable) with fully tax-free EEE returns. The example below is calculated by this page's real engine from the displayed inputs.

1Enter the amount you expect to invest each financial year, within the limits applicable to your account.
2Enter the expected investment duration. PPF has a long-term structure, so use the calculator for planning rather than short-term cash needs.
3Enter the current or assumed annual rate for an estimate. Official rates and terms can change.
4Compare your total contribution with estimated interest growth to understand the long-term compounding effect.

Input	Example value	Why it matters
Yearly contribution	150000 ₹	Statutory limit ₹1,50,000 per financial year
PPF interest rate	7.1 % p.a.	Measured or known ppf interest rate used by the calculation engine.
Tenure	15 years	15 years, extendable in blocks of 5
Your tax slab (for comparison)	30 %	Measured or known your tax slab (for comparison) used by the calculation engine.

Formula, derivation and worked example

PPF is an Exempt-Exempt-Exempt instrument: the contribution is deductible under Section 80C, the interest is untaxed and the maturity is untaxed. That makes its effective pre-tax equivalent far higher than the headline rate — at a 30% slab, 7.1% tax-free equals roughly 10.1% taxable. The model credits interest annually on contributions made before the 5th of April.

Balanceᵧ = (Balanceᵧ₋₁ + Contribution) × (1 + r)

Interest is credited annually on the lowest balance between the 5th and last day of each month

Maturity = Balance after 15 years (EEE — fully tax-free)

Taxable-equivalent yield = r / (1 − slab%)

Substitution steps

1. Annual contribution
A
= ₹150,000
2. Annual rate
7.1%
= 7.10%
3. Compounding
(Bal + A) × (1 + r) each year
= 15 cycles
4. Maturity
Balance after final year
= ₹4,068,209
5. Tax-free advantage
r / (1 − 30%)
= 10.14%

Computed example results

Maturity amount (tax-free): ₹4,068,209
Total contributed: ₹2,250,000
Interest earned: ₹1,818,209
Taxable-equivalent yield: 10.14%; Equal to 10.14% in a taxable deposit at 30% slab
80C deduction claimed: ₹2,250,000; Old regime only
Growth multiple: 1.81×

Understanding the result

Read the main result together with supporting checks, assumptions, limits and intermediate values.

For a manual check, repeat the first equation, confirm the units and change one input at a time.

Common mistakes when using PPF Calculator

Do not mix units for Yearly contribution (₹), PPF interest rate (% p.a.), Tenure (years). A unit mismatch changes the input magnitude even when the typed number looks reasonable.
Do not replace the displayed Balanceᵧ = (Balanceᵧ₋₁ + Contribution) × (1 + r) relationship with a different convention without also changing the underlying assumptions; compare like-for-like methods when checking the result.
Do not treat Maturity amount (tax-free) = ₹4,068,209 from the worked example as a universal answer. It belongs to the displayed example inputs and must be recalculated for the actual case.

What is PPF?

Public Provident Fund is a long-term savings scheme designed for regular contributions and compounding over an extended period.

It is commonly used as one part of a diversified long-term savings plan, alongside emergency funds, insurance and investments suited to the person's risk profile.

Why start early?

Earlier contributions receive more compounding periods. Consistent yearly deposits can have a significant effect over a long investment horizon.

Before investing, check the official rules for lock-in, extension, loans, withdrawals, annual contribution limits and tax treatment.

Formula

Balanceᵧ = (Balanceᵧ₋₁ + Contribution) × (1 + r)
Interest is credited annually on the lowest balance between the 5th and last day of each month
Maturity = Balance after 15 years (EEE — fully tax-free)
Taxable-equivalent yield = r / (1 − slab%)

Formulas explained

Future value = yearly contribution accumulated with annual compounding

Each annual contribution receives interest for a different number of years, so earlier contributions have more time to compound.

Contribution: Amount deposited each year
Rate: Annual assumed PPF interest rate
Years: Number of annual compounding periods

This calculator is for estimation. Always verify current contribution limits, rate announcements, withdrawal rules and tax treatment through official sources.

Assumptions

Contribution is made at the start of each financial year (best case for interest).
The rate is held constant, though the government resets it quarterly.
No partial withdrawals or loans against the balance.

Tips

Deposit before the 5th of April to earn a full year of interest on the whole amount.
After 15 years, extend in 5-year blocks with or without further contribution.
Partial withdrawal is allowed from year 7 — useful as a low-risk goal bucket.

Warnings

Contributions above ₹1.5 lakh in a year earn no interest and are refunded.
The account cannot be closed before 5 years except on specified medical/education grounds.

No. Applicable rates and product rules can change. Use the calculator for an estimate and confirm the current rate through official channels.

Can I withdraw PPF money early?

PPF has specific lock-in and withdrawal conditions. Check the current official rules before treating it as short-term savings.
