Understanding lumpsum calculator
A lump sum puts the entire investment into the modeled portfolio at the start. Compare the same investment over different holding periods, and include a lower-return scenario. Unlike a SIP, this calculation has no later contributions; adding money changes the cash-flow pattern.
Formula and calculation method
Lumpsum future value = investment × (1 + annual effective return)^years.
All rates are illustrative, editable assumptions, not live quotations or guaranteed returns. Fees and taxes are excluded unless entered. Compare scenarios using the same contribution timing and return convention.

Factors affecting your result
All rates are illustrative, editable assumptions, not live quotations or guaranteed returns. Fees and taxes are excluded unless entered. Compare scenarios using the same contribution timing and return convention.
Changing one-time investment changes the scenario being evaluated. Adjust one input at a time when comparing results, keep a copy of the assumptions, and compare values using the same unit and period. A precise arithmetic result does not make an uncertain assumption precise.
