SIP Calculator

Calculate returns on a Systematic Investment Plan in mutual funds

SIP Details

Equity funds 12–15% · Balanced 10–12% · Debt 7–9% p.a., historically.
Raise the instalment by this much every year, in line with your salary. Leave at 0 for a level SIP.

Returns are assumed to compound monthly, with each instalment invested at the start of the month — the same convention AMFI and the AMCs use.

Investing ₹5,000 a month for 10 years at 12% could grow to about ₹11.62 lakh, of which ₹5.62 lakh is growth.

How this is calculated

Formula

FV = P × [((1 + i)ⁿ − 1) / i] × (1 + i)

FV
= future value of the SIP
P
= monthly instalment
i
= monthly rate = annual rate ÷ 12 ÷ 100
n
= number of instalments = years × 12

With your numbers

  1. 1Monthly ratei = r ÷ 12 ÷ 10012.0% ÷ 12 ÷ 100 = 0.010000
  2. 2Number of instalmentsn = years × 1210 × 12 = 120
  3. 3Compound the instalmentsFV = P × [((1 + i)ⁿ − 1) / i] × (1 + i)₹5,000 × [((1 + 0.010000)^120 − 1) ÷ 0.010000] × (1 + 0.010000) = ₹11,61,695
  4. 4Split the resultgrowth = FV − (P × n)₹11,61,695 − ₹6,00,000 = ₹5,61,695 of growth on 120 instalments

  • The trailing × (1 + i) is what makes this a SIP rather than an ordinary annuity: each instalment is invested at the start of the month, so it earns a full month of return.
  • Set a step-up above zero and each year gets its own instalment, compounded separately and summed, because the closed form above assumes a constant P.
  • No exit load, expense ratio drag or capital gains tax is deducted. The expected return you enter should already be net of the fund’s expense ratio.

What is a SIP?

A Systematic Investment Plan is a way of investing in mutual funds where you put in a fixed amount at regular intervals — usually monthly — instead of a lump sum.

It gives you rupee cost averaging and the benefit of compounding, which is why it suits long-term wealth building on a salary.

What this tool will not do

It will not name a fund, rank an AMC or send you to a broker. BullTimes earns nothing from where you invest, so there is nothing to steer you towards.

What it does is show the arithmetic on the assumptions you supply — including the assumption most likely to be wrong, which is the expected return.

Each instalment is invested at the start of the month and compounds monthly. A projection at a constant return, not a forecast.

Worked examples

₹5,000 a month for 15 years

At 12%, ₹9,00,000 paid in grows to ₹25,22,880: ₹16,22,880 of it is growth. Five more years than the table above add ₹13,61,185.

₹10,000 a month for 20 years

₹24,00,000 paid in becomes ₹99,91,479 at 12%. Growth is 76% of the final corpus, because the early instalments compound for almost two decades.

Open this in the calculator

₹5,000 a month, stepped up 10% a year, for 15 years

The instalment reaches ₹20,886 in year 15. The corpus is ₹43,41,925, against ₹25,22,880 for the same SIP left level: ₹18,19,045 more, for ₹10,06,349 more paid in.

Common mistakes

  • Treating instalments as paid at the end of the month

    A SIP instalment is invested at the start of the month, so it earns that month's return too. Calculators that use the ordinary annuity formula (no trailing × (1 + i)) drop a month of growth on every instalment: on the table above, ₹11,502 less than the AMC convention gives.

    SIP conventions
  • Entering a return before the expense ratio

    The return you enter is applied as it is. A fund’s published returns are already net of its expense ratio, but an index return or a "market average" is not: subtract the fund’s ongoing costs from those first.

    What is and is not deducted
  • Reading the corpus as today’s money

    ₹11,61,695 in 10 years buys what about ₹6,48,685 buys today, if prices rise 6% a year. Compare a target with the corpus in the same terms.
