The formula
The calculation uses a standard, verifiable formula. Here it is in its simplest form.
What each variable means
| Symbol | Name | Description |
|---|---|---|
| I | Initial savings | The amount you have saved at the start. |

| n | Months | The savings period in months. |
Step-by-step example
Example: ₹50,000 initial + ₹10,000/month at 6% for 10 years
- 1Monthly rate = 6% ÷ 12 = 0.5% = 0.005
- 2Months = 10 × 12 = 120
- 3Initial growth ≈ 50,000 × (1.005)^120 ≈ ₹90,970
- 4Monthly deposits growth ≈ ₹16,40,000
- 5Total savings ≈ ₹17,31,000
- 6Amount saved = 50,000 + 10,000 × 120 = ₹12,50,000
- 7Interest earned = 17,31,000 − 12,50,000 = ₹4,81,000
Result
≈ ₹17.31 lakh total savings
