Lumpsum Calculator — FV Explained
Published July 20, 2026By Samson PG
One deposit, assumed annual return, time. Here is the lumpsum growth model without pretending it is personalized investment advice.
A lumpsum projection answers: if I invest a single amount today at an assumed annual return for n years, what might the future value be? TryCalculatingNow’s calculator is illustrative math only — not investment, tax, or product advice.
Formula (annual compound)
FV = P × (1 + r)^n
| Symbol | Meaning |
|---|---|
| P | Principal (one-time investment) |
| r | Assumed annual rate as a decimal (12% → 0.12) |
| n | Years |
| FV | Future value illustration |
Products that compound monthly or daily, or charge fees, will differ. Treat the output as a scenario, not a promise.
Worked example (illustration)
₹100,000 at 12% for 10 years (annual compound):
100,000 × (1.12)^10 ≈ ₹310,585
Change the rate or years and the path moves quickly — that sensitivity is the point of the tool.
Lumpsum vs SIP vs compound + contributions
| Model | Cash flow | Typical question |
|---|---|---|
| Lumpsum | One deposit | “What if I invest this bonus?” |
| SIP | Regular deposits | “What if I invest monthly?” |
| Compound + monthly | Starting balance + deposits | Mixed scenarios |

Inflation reminder
A large nominal corpus is not spending power. Pair long horizons with an inflation calculator when you care about real goals.

FAQ
Is the rate the same as a fund’s CAGR?
No. Calculators use an assumed rate. Actual returns vary.
Monthly compounding?
This tool compounds yearly for a clear estimate. For finer schedules, use the compound interest calculator.
Does lumpsum beat SIP?
It depends on timing, amount, and returns — not a universal rule. Model both; do not treat either output as advice.
Is my data uploaded?
