Examples
150,000 per year at 7.1% for 15 years
Depositing the full 150,000 yearly at 7.1% for 15 years matures to about 4,068,209 on 2,250,000 deposited.
- Yearly rate r = 0.071 and years n = 15, with deposits at the start of each year.
- Maturity = 150,000 x ((1.071^15 - 1) / 0.071) x 1.071 = 150,000 x 25.3589 = 4,068,209 (rounded).
- Interest = 4,068,209 - 2,250,000 = 1,818,209, fully tax-free under EEE status.
50,000 per year at 7.1% for 15 years
Depositing 50,000 yearly at 7.1% for 15 years matures to about 1,356,070 on 750,000 deposited.
- Same factor 25.3589 as above since rate and tenure match: maturity = 50,000 x 25.3589 = 1,356,070 (rounded).
- Total deposited = 50,000 x 15 = 750,000, so interest = 1,356,070 - 750,000 = 606,070.
- Tripling the deposit to 150,000 triples the maturity to 4,068,209, showing PPF scales linearly with deposits.
