PPF Calculator
Public Provident Fund maturity over 15 years (extendable) with fully tax-free EEE returns.
Inputs
Statutory limit ₹1,50,000 per financial year
15 years, extendable in blocks of 5
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%)
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.

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.
