Mutual fund calculator

This mutual fund calculator combines a lumpsum investment with a monthly SIP and an optional annual step-up. It shows the projected value, the annualised return (XIRR) and what the result is worth after inflation.

Educational tools built on standard formulas. Every figure below is illustrative, computed from the inputs you enter — not a projection, recommendation or guarantee.

SIP Calculator

The future value of a monthly SIP over your chosen horizon, assuming a constant expected rate of return. Instalments are treated as invested at the start of each month.

The method

How the mutual fund calculator works

Both parts grow at the same effective annual rate you enter. The lumpsum compounds annually. SIP instalments compound monthly at the equivalent monthly rate, so the overall annualised return matches your assumption.

Lumpsum: FV = L × (1 + r)^t Monthly rate: i = (1 + r)^(1/12) − 1 Step-up SIP: instalment rises by s% every 12 months

The annualised return is a true XIRR across every cash flow, which accounts for later instalments having less time to grow. Expense ratio, exit load and capital gains tax are not modelled.

Worked example (the calculator's default inputs)

Lumpsum investment
₹1,00,000
Monthly SIP
₹10,000
Expected return
12% a year
Period
10 years
Total invested
₹13,00,000
Projected value
₹25,50,944
Annualised return (XIRR)
12.00%

From the lumpsum: ₹3,10,585. From the SIP: ₹22,40,359.

The essentials

Lumpsum, SIP and step-up SIP in one mutual fund calculator

Using it as a lumpsum calculator

Set the monthly SIP to zero and the tool works as a lumpsum calculator: it compounds a one-time investment at the return you assume, FV = L × (1 + r)^t. A ₹1,00,000 lumpsum at 12% for 10 years grows to about ₹3.11 lakh.

Using it as a step-up SIP calculator

Enter an annual step-up percentage and your SIP rises by that amount every year, for example 10%, so contributions keep pace with a rising income. Because later instalments are larger and have less time to compound, the XIRR stays at your assumed rate while the final value rises.

SIP calculator with inflation

The "value in today's money" figure divides the projected value by inflation over the same period. It answers a practical question: what the future amount would buy at today's prices. If you only need a plain monthly SIP projection, the SIP calculator is simpler, and the overlap calculator checks whether the funds you hold are genuinely different.

Common questions

Mutual Fund Calculator: frequently asked questions

Still have questions? Contact us
Why does the XIRR match the return I entered?
Because both the lumpsum and the SIP grow at the same effective annual rate. The SIP uses the monthly rate that compounds to your annual rate, rather than the annual rate divided by 12.
Can I use this as a lumpsum calculator?
Yes. Set the monthly SIP to zero and enter only the one-time amount. The calculator then shows what a lumpsum investment could grow to at your assumed return.
What does an annual step-up SIP do?
It raises your monthly SIP by a fixed percentage every year, for example 10%, so contributions keep pace with a rising income. Later, larger instalments have less time to compound, which the XIRR reflects.
How is the inflation-adjusted value calculated?
The projected value is divided by (1 + inflation) raised to the number of years. The result is what the future amount would be worth in today's money.
Does the projection include tax and fund charges?
No. Expense ratio, exit load and capital gains tax are not included, and each will reduce what you actually receive.
