Future value of a lumpsum: FV = P × (1+r)^n, where P is the principal, r is the monthly interest rate (annual ÷ 12), and n is the number of months. Interest is compounded monthly.
What is lumpsum investment?
A lumpsum investment is when you invest a single amount at one time, as opposed to investing regularly (e.g. SIP).
Is the return guaranteed?
No. The calculator uses the expected return you enter. Actual returns depend on the product and market.
Monthly vs annual compounding?
We use monthly compounding. For annual compounding the result would differ slightly.
