A lump sum benefits most from compounding when invested early, but timing matters more than with an SIP. Equity mutual funds in India have historically returned around 10–14% a year over long periods, with big swings.

How it works
Enter the amount invested, the expected annual return, the period and inflation.
Inputs explained
| Field | What to enter |
|---|---|
| Total investment | Amount in ₹ |
| Expected return (p.a.) | In % |
| Time period | In years |
| Inflation | In % |
What each result means
- Total value = [Total investment]×(1 + [Expected return (p.a.)]÷100)^[Time period]
- Estimated returns = [Total value] – [Total investment]
- Value in today’s money = [Total value]÷(1 + [Inflation]÷100)^[Time period]
Example values
How the main result changes when Total investment changes and everything else stays at the example values above:
| Total investment | Total value |
|---|---|
| 50,000 | 155,292.41 |
| 75,000 | 232,938.62 |
| 100,000 | 310,584.82 |
| 125,000 | 388,231.03 |
| 150,000 | 465,877.23 |
| 200,000 | 621,169.64 |
Formula
Future value = P × (1 + r)^years
Real value = future value ÷ (1 + inflation)^years
Worked example
Inputs: Total investment: ₹100,000; Expected return (p.a.): 12 %; Time period: 10 years; Inflation: 5 %.
Results: Total value = ₹310,584.82; Estimated returns = ₹210,584.82; Value in today's money = ₹190,672.14.
