Investment maths — assumptions are yours

SIP vs lumpsum calculator

Future value of a monthly SIP and a one-time lumpsum, side by side, at the same expected return. Both are computed transparently — nothing is recommended.

An assumption, not a promise — equity returns vary widely.

  1. SIP (instalment at the start of each month):
    FV = P × [((1+i)ⁿ − 1) ÷ i] × (1+i), where i = annual return ÷ 12 and n = months.
  2. Lumpsum (expected CAGR compounded annually):
    FV = P × (1+r)ᵗ.

Both assume the rate stays constant — real returns don't. Taxes and exit loads are not modelled; see the capital-gains calculator for tax on redemption.

SIP or lumpsum — what this page computes

A SIP (systematic investment plan) invests a fixed amount every month, so your money enters the market gradually at many price points. A lumpsum invests everything on day one, so the full amount compounds for the whole tenure. This page computes the arithmetic of both at a constant expected return — it does not tell you which to choose, because the answer depends on whether you already have the lumpsum, market conditions, and your own risk tolerance.

For information only — not investment advice. Expected returns are your assumption; mutual-fund returns are market-linked and not guaranteed. This page computes projections; it does not recommend any product or investment style.
