Mathematical Formula
Overview & Explanation
PPF is a government-backed 15-year savings scheme. Interest is calculated on the lowest balance between the 5th and the end of each month and credited annually, so depositing before 5 April earns interest for the full year.
How It Works
- Assume the yearly deposit is made before 5 April.
- Each year: balance = (previous balance + deposit) × (1 + i).
- After n years the closing balance is the maturity value.
Practical Applications
- Tax-free long-term saving (EEE status).
- Section 80C planning under the old regime.
Example 1: ₹1.5 lakh/year for 15 years at 7.1%
Maximum deposit.
Inputs
Yearly deposit (₹): 150000 · Interest rate (% p.a.): 7.1 · Duration (years): 15
Step 1
Each year: balance = (previous balance + 1,50,000) × (1 + 7.1/100)
Step 2
Repeated for 15 years (see table).
Maturity value
Result
Example 2: ₹50,000/year for 20 years at 7.1%
With one 5-year extension.
Inputs
Yearly deposit (₹): 50000 · Interest rate (% p.a.): 7.1 · Duration (years): 20
Step 1
Each year: balance = (previous balance + 50,000) × (1 + 7.1/100)
Step 2
Repeated for 20 years (see table).
Maturity value
Result
How it's calculated & sources
Maturity = D × [((1 + i)^n − 1) / i] × (1 + i), where D = yearly deposit made by 5 April, i = rate / 100, n = years. Interest is compounded annually.
