Comparison
How Lumpsum vs SIP works
The lumpsum path invests the full amount on day one and compounds for the entire SIP spread period. The SIP path divides the same total into equal monthly instalments over that period. Both use the same expected return - the comparison shows timing and rupee-cost averaging effects.

What the Lumpsum vs SIP Calculator tells you
This calculator helps you compare investing cash today with spreading contributions across months. It turns a small set of inputs into a clear side-by-side maturity, then shows the supporting breakdown so you can understand what moved the answer.
Inputs to check
- Lump amount: use a recent statement, quote or realistic assumption.
- Monthly SIP: use a recent statement, quote or realistic assumption.
- Return and period: use a recent statement, quote or realistic assumption.
Try three scenarios
Run a likely case, a conservative case and a better case. Change one input at a time so you can see which assumption matters most.
How to use this estimate in a real decision
Write down the values you entered and the date you checked them. Compare options using the same assumptions, then include any fee, tax, penalty or provider rule that sits outside the calculator. A mathematically precise answer can still be incomplete when the inputs are old or optimistic.
Treat the result as a planning range, not a quote, approval or guaranteed outcome. Recalculate whenever your rate, price, income, goal date or business cost changes.
