Frequently asked questions
Complete guide to Lump Sum Calculator
What is a lump sum calculator?
A lump sum calculator shows how a one-time investment grows over time with compound interest. Enter the initial amount, expected annual return, and number of years. It is useful for planning a single deposit (e.g. bonus, inheritance, sale of asset) and comparing different rates or time horizons. For regular contributions, use a SIP or savings calculator instead.
When to use a lump sum vs SIP
Use a lump sum calculator when you have a single amount to invest (e.g. windfall, bonus). Use a SIP calculator when you invest a fixed amount regularly (e.g. monthly). Historically, lump sum investing has often outperformed dollar-cost averaging over long periods, but SIPs help with discipline and reducing timing risk.
