Calculate
SIP / RD Calculator
Projected value of a monthly SIP or recurring deposit, or a one-time investment, with optional annual step-up.
A Systematic Investment Plan invests a fixed amount every month. This calculator compounds those instalments at an assumed annual return so you can see the projected corpus, how much of it is your own money and how much is growth.
A recurring deposit works the same way arithmetically — a fixed sum every month, compounded — so the monthly mode covers an RD too. The difference is certainty rather than formula: a bank quotes the RD rate in advance and is contractually bound to it, while a SIP return is only ever an assumption. Treat the RD figure as reliable and the SIP figure as an illustration.
A step-up SIP increases the instalment by a fixed percentage every year — usually in line with your salary increments. Banks do not normally allow a running RD to be stepped up; to model that, open a fresh RD for the higher amount.
How it is calculated
Monthly SIP (no step-up)
- FV = P × ((1 + i)^n − 1) ÷ i × (1 + i)
- P = monthly instalment, i = monthly return = annual ÷ 12 ÷ 100, n = number of instalments
- Instalments are assumed to be invested at the start of each month.
Step-up SIP
- Each year’s instalment is increased by the step-up percentage and compounded for its remaining months.
Lump sum
- FV = P × (1 + annual rate ÷ 100)^years
Things to keep in mind
- The return you enter is an assumption, not a promise. Mutual fund investments are subject to market risk — read all scheme related documents carefully. For a recurring deposit, use the rate your bank has actually quoted for that tenure.
- Recurring deposit interest is taxable at your slab rate as it accrues, and banks deduct TDS once it crosses the section 194A threshold. The maturity figure here is before any tax.
- Exit load, expense ratio, stamp duty and capital gains tax are not deducted. Use the Capital Gains Calculator to estimate tax on redemption.
