The Public Provident Fund is a long-horizon, government-backed small savings avenue with annual compounding in official calculations.
This page models equal yearly deposits and a flat rate—actual rules, ceilings, and rate notifications change with finance ministry updates.
PPF Calculator — key points
- Caps yearly deposit at ₹1.5 lakh for illustration
- Splits maturity into deposits vs interest
- Adjustable tenure and rate
Planning perspective
Helpful for back-of-envelope discipline checks alongside passbook entries.
- Extension blocks and partial withdrawals are not simulated.
- Use official forms for exact interest application dates.
Annuity-due style yearly buildup (illustrative)
FV ≈ PMT × [ ((1 + g)^n − 1) / g ] × (1 + g) (equal yearly PMT, rate g, n years—simplified).
Symbols
- PMT — Yearly contribution (subject to statutory cap).
- g — Yearly interest rate as decimal.
- n — Years in the model.
Reality check
Government-published rates and compounding quirks can differ; treat output as educational, not a passbook replacement.
Benefits
- Shows interest share of maturity at a glance.
- Encourages early-year contribution habits conceptually.
Frequently asked questions
- Joint account?
- Rules are per scheme guidelines; this is single-depositor math.
- Tax benefit?
- Discuss with a tax adviser—this tool does not compute Section 80C limits.
