How this calculator works

A lumpsum investment is a single amount put in once and left to compound. The maths is the plainest form of compound growth: multiply by one plus the rate, once for every year.

The comparison panel exists because the SIP-versus-lumpsum question comes up constantly. Investing the same total amount as a SIP almost always produces a smaller final value at the same assumed return — not because SIPs are worse, but because in a SIP the average rupee is invested for roughly half the period.

That arithmetic advantage assumes the return actually materialises. A lumpsum invested immediately before a sharp fall takes years to recover, while a SIP spanning the same period buys through the fall at lower prices. Which approach ends up ahead depends on the path markets take, which nobody knows in advance.

The practical distinction is usually simpler than the theory: if you already have the money, a lumpsum is the question. If you are investing out of monthly income, a SIP is the only option available.

The formula

Compound growth

FV = P × (1 + r)ⁿ

P
Amount invested today
r
Annual return as a decimal
n
Number of years

Worked example: ₹5 lakh at 12% for 10 years

Vikram invests ₹5,00,000 as a lumpsum and assumes 12% annual growth for 10 years.

The lumpsum ends roughly 60% ahead of the equivalent SIP at the same assumed return, because the whole amount compounds for the full ten years rather than an average of five.

Things worth knowing

  • Market-linked returns are not guaranteed. The rate you enter is an assumption, not a prediction, and actual returns will be higher in some years and negative in others.
  • Compounding is assumed annually here. Funds do not literally compound once a year, but for a projection over several years the difference is immaterial next to the uncertainty in the return itself.
  • The projection is before tax and before any exit load. Both reduce what you actually receive.
  • A lumpsum invested just before a market fall can take years to recover. If the amount is large relative to your total savings, staggering it over several months is a common way to reduce that risk.
  • For money you will need within three to five years, a market-linked lumpsum is usually the wrong vehicle regardless of the projection. The variance over short periods is too high.

Frequently asked questions

Is a lumpsum better than a SIP?
At the same assumed return, a lumpsum produces more, because the money compounds for longer. In the real world it also carries more timing risk: everything is exposed to whatever happens next. If you have a large sum and a long horizon, many investors stagger it over several months to reduce that exposure without giving up too much compounding.
What is a realistic return to assume?
That depends entirely on what you invest in. Equity funds have historically been more volatile with higher long-run averages; debt funds are steadier and lower. Whatever you assume, run the numbers again at a lower rate and check whether the plan still works.
How is a lumpsum mutual fund investment taxed?
Tax depends on the fund type and how long you hold it. Equity and debt funds follow different rules, with different holding periods and rates, and equity gains have an annual exemption threshold. Check the current provisions before redeeming.
