Step-Up SIP Calculator

A SIP that rises with your income each year, compared against a flat one. Stepping up by 10% a year roughly doubles the outcome over fifteen years. Most of it from instalments you had not yet started making.

Also called: top up sip calculator, increasing sip calculator.

Maturity value

₹86,83,849

₹86,83,849 after 15 years. A flat SIP at the same starting amount would reach ₹50,45,760. Stepping up by 10% a year adds ₹36,38,089.

How this is calculated

An estimate, not an offer or a guarantee. Projected returns assume the rate you entered holds for the whole term, which no market does.

Method and background

This is what the calculation gives for the numbers you entered. It is an estimate, not advice, and it knows nothing about your situation beyond those numbers. Rules for India change on a published schedule; the effective date is shown on every rule-based tool.

How this is calculated

Each year is its own twelve-month annuity at that year's instalment, and the result compounds for the remaining years. Summing the year-blocks is exact and avoids the approximation of treating the whole thing as one growing annuity. The comparison against a flat SIP is the useful output: the advantage is large and almost entirely back-loaded.

FV = sum over years of: P*(1+g)^(y-1) * annuity_due(12 months) * (1+i)^(12*(Y-y))

P: Starting instalment (currency)
g: Annual step-up (decimal)
i: Monthly return (decimal)
Y: Years (years)

10% step-up over 15 years

Starting monthly investment: ₹10,000
Annual increase: 10%
Expected return (per year): 12%
Investment period (years): 15

Maturity value₹86,83,849

geometric identity: 10000 x 1.1^14 = 37,975

Open this example

zero step-up equals a flat SIP

Starting monthly investment: ₹10,000
Annual increase: 0%
Expected return (per year): 12%
Investment period (years): 10

Maturity value₹23,23,391

degenerate case: with g=0 this must reduce exactly to the DRV-005 SIP result

Open this example

zero return returns the sum of instalments

Starting monthly investment: ₹10,000
Annual increase: 10%
Expected return (per year): 0%
Investment period (years): 3

Maturity value₹3,97,200

degenerate case: 12 x 10000 x (1 + 1.1 + 1.21) = 397,200

Why two SIP calculators give you different answers · 2 min · Put the same numbers into two SIP calculators and they disagree by tens of thousands. Neither is broken. They are answering slightly different questions.

Method and limits

What it assumes

The return you enter is assumed to hold, unchanged, for the whole period. No market does this.
Returns are compounded at the stated frequency with no taxes, fees or exit loads deducted.
The step-up is applied once a year, on the anniversary.
