About this calculator
A lump sum calculator is the cleanest way to project how a one-time investment could grow without the extra complexity of recurring contributions.
It is especially useful alongside SIP planning because investors often compare a lump sum deployment with a staggered monthly strategy.
Frequently asked questions
Is a lump sum better than SIP?
Neither is automatically better. A lump sum gives full time-in-market immediately, while SIP spreads entry over time.
Why can small return differences matter so much over time?
Compounding magnifies even modest changes in annual return when the holding period is long.
Can this be used for equity and debt products?
Yes. The calculator is generic; the quality of the output depends on how realistic the chosen return assumption is.
