Step-Up SIP Calculator

A step-up SIP calculator (also searched as a step SIP calculator, or a SIP calculator with increment) that projects the future value of a SIP whose monthly investment grows every year — and compares it side by side against a flat SIP of the same starting amount, so you can see exactly how much a yearly increase is worth.

Your SIP amount increases by the step-up % every 12 months — e.g. a ₹10,000/month SIP with a 10% annual step-up becomes ₹11,000/month in year 2, ₹12,100/month in year 3, and so on.

Flat SIP vs. step-up SIP

Same ₹10,000.00/month starting amount, same tenure, same return — with vs. without the 10% annual step-up.

Stepping up by 10% a year yields ₹36,38,089.44 more (72.1%) than a flat SIP of the same starting amount — for ₹20,12,697.80 more invested over the 15-year tenure.

What a step-up SIP is, and why it matches how your income actually grows

A flat SIP ignores your rising income

Most people's salary rises every year, but a standard SIP keeps the same contribution fixed for the entire tenure — so as your income grows, the SIP quietly becomes a smaller and smaller share of what you earn. A step-up SIP (also called a top-up SIP) fixes this by increasing the monthly investment automatically, typically once a year, so your savings rate keeps pace with your income instead of falling behind it.

Small yearly increases compound into a much larger difference

Because each year's higher contribution keeps compounding for the rest of the tenure, even a modest step-up — 5% or 10% a year — can add up to a meaningfully larger corpus than a flat SIP by the end of a long tenure, without ever feeling like a large jump in any single year. The side-by-side comparison in the calculator above is built specifically to make that difference concrete for your own numbers.

Step-up SIP still depends on your cash flow keeping pace

A step-up SIP only works smoothly if your income actually rises enough to absorb the higher contribution each year — committing to a step-up % well above your realistic income growth can strain your monthly budget instead of quietly fitting into it. Pick a step-up % you're confident you can sustain, not just the highest one that produces the biggest projected number.

Frequently asked questions

What is a step-up SIP?

A step-up SIP (also called a top-up SIP) is a Systematic Investment Plan where your monthly investment amount increases automatically by a fixed percentage every year, instead of staying flat for the entire tenure. For example, a ₹10,000/month SIP with a 10% annual step-up becomes ₹11,000/month in year 2, ₹12,100/month in year 3, and so on — most mutual fund platforms and this step-up SIP calculator let you model that increase before you commit to it.

How much should I increase my SIP each year?

There's no fixed rule, but a common approach is to match your step-up % to your expected annual income growth — many salaried investors use 8-10%, roughly in line with typical annual increments, so the higher SIP amount never demands a lifestyle sacrifice. Use the step-up % field above to test a few values (5%, 10%, 15%) against your own numbers and see how much difference it makes to the future value.

Is step-up SIP better than a flat SIP?

A step-up SIP almost always builds a larger corpus than a flat SIP of the same starting amount, because your contributions grow over time instead of staying fixed while inflation erodes their real value — the side-by-side comparison above shows exactly how much more for your own numbers. That said, "better" depends on your income trajectory: a step-up SIP only works if your cash flow can actually support the rising contribution each year, so it isn't automatically the right choice for every investor.

How is step-up SIP future value calculated?

Unlike a flat SIP, a step-up SIP has no single simple formula — the monthly contribution changes every 12 months, so each year's contributions compound forward for a different number of remaining months. This calculator computes it month by month: each month's investment is added and grows at your expected rate of return, compounding, until the end of the tenure.

Is this step-up SIP calculator free?

Yes — it's free, runs entirely in your browser, and requires no signup. Nothing you enter is sent to a server or stored anywhere.
