Compare Lumpsum scenarios
Change one input, hold everything else identical, and see how much that one input is actually worth. The gap between the scenarios is the whole answer.
What to compare
Everything else below is held identical across the scenarios, so the only thing separating the lines is this one input.
Shared by every scenario
An assumption you choose, not a forecast.
Side by side
| Scenario | Investment amount | Projected value |
|---|---|---|
| Scenario A | ₹2,50,000 | ₹7,76,462 |
| Scenario B | ₹5,00,000 | ₹15,52,924 |
| Scenario C | ₹7,50,000 | ₹23,29,386 |
Moving investment amount from ₹2,50,000 to ₹7,50,000 changes projected value by +₹15,52,924. Every other input was identical in both.

Scenario A — ₹2,50,000
Write the return as a decimal
12% ÷ 100
= 0.12
Grow one rupee for the whole period
(1 + 0.12)^10
= 3.105848
Multiply by the amount invested
₹2,50,000 × 3.105848
= ₹7,76,462
Scenario B — ₹5,00,000
Write the return as a decimal
12% ÷ 100
= 0.12
Grow one rupee for the whole period
(1 + 0.12)^10
= 3.105848
Multiply by the amount invested
₹5,00,000 × 3.105848
= ₹15,52,924
Scenario C — ₹7,50,000
Write the return as a decimal
12% ÷ 100
= 0.12
Grow one rupee for the whole period
(1 + 0.12)^10
= 3.105848
Multiply by the amount invested
₹7,50,000 × 3.105848
= ₹23,29,386
Every scenario is computed by the same engine the projected value calculator uses, so the last line of each is the figure in the table above. Intermediate values are shown rounded for reading; the calculation carries full precision throughout.
Over time
Each line is one scenario. Because every other input is identical, the gap between them is the effect of investment amount alone.
How to read this
- Only one input differs. Every other value is identical across the scenarios, which is what makes the gap between them readable. If each scenario had its own assumed return, the chart would be comparing guesses rather than choices.
- A bigger number is not automatically better. On a loan comparison the larger figure is the worse one, and on any of these the right answer depends on circumstances this page knows nothing about.
- The rate is still an assumption. Comparing scenarios does not make any of them a forecast — it only shows how sensitive the outcome is to the input you changed.
