Estimate one-time investment growth
A lumpsum calculator is useful when you want to invest a single amount and understand how it may grow over a defined period. It is often used for surplus cash deployment, bonus investments, and long-term goal planning.
Changing the expected return helps you compare cautious and optimistic growth assumptions before making an investment decision.
How to read the lumpsum output
Compare future value and absolute return together to understand the growth generated by your invested capital. The time horizon matters greatly because compounding gets stronger over longer periods.

Frequently asked questions
When should I use a lumpsum calculator instead of a SIP calculator?
Use a lumpsum calculator when you plan to invest one amount upfront. Use a SIP calculator when you want to invest smaller amounts regularly every month.
Does this include market risk?
No. It is an estimate based on the return you enter. Actual outcomes depend on real market performance and may vary from the projection.
