Lumpsum calculator
Invest once and leave it to grow. See the final value, and what it would buy in today's prices.
An estimate, not a promise. Market-linked returns change every year.
Year by year
How lumpsum growth is worked out
P is the amount you invest, r is the yearly return as a decimal (12% = 0.12) and t is the number of years. Each year's gains are added to the amount, so the next year grows on a bigger base. That is compounding.
The "in today's money" figure divides the result by (1 + inflation)ᵗ. It shows what the future amount could buy at today's prices.
Lumpsum or SIP: which is better?
A lumpsum has more time in the market, so it usually ends higher if markets rise steadily. A SIP spreads your buying over many months, which softens the effect of a bad time to start. Compare both with the SIP calculator.
How long does it take to double my money?
Divide 72 by the yearly return. At 12% a year, money roughly doubles in 6 years. This is called the rule of 72.
