One-time investment growth. The Lumpsum Investment Calculator takes lump sum invested, expected annual return, years and returns estimated value plus estimated gains, growth multiple. Results update as you type, and the formula is shown under the result so you can repeat it in your own spreadsheet.
Government-backed schemes publish their interest rates quarterly and market-linked funds do not guarantee returns. Enter the current rate for the scheme and treat market-return assumptions as scenarios rather than promises. Use the worked example below to check the maths against your own figures.
How the Lumpsum Investment Calculator works
A one-time investment compounds yearly at the assumed return. ₹5 lakh at 12% for ten years becomes about ₹15.5 lakh, three times the original.
Worked example
With the example values (lump sum invested of ₹500,000, expected annual return of 12%, years of 10 years), the estimated value is ₹1,552,924.10; estimated gains ₹1,052,924.10, growth multiple 3.11x. Change any figure above and the result updates immediately; use Copy results to paste the summary into a note or email.

Frequently Asked Questions
How is estimated value calculated?
value = amount × (1 + return)years.
Which figures do I need?
Lump sum invested, expected annual return, years. Take them from the same period and the same set of accounts or reports so the ratio is consistent, and check the example values as a guide to the units expected.
Is the interest rate fixed?
Small-savings rates are reviewed by the government every quarter and bank rates change with policy; market-linked schemes have no fixed rate at all. Enter the current rate for your scheme and revisit the result when rates change.
