Your SIP
Raise the amount by this much every year. A 10% step-up usually beats chasing 2% more return.

Notice where the blue overtakes the navy. Compounding does almost nothing early and almost everything late.
Why this number may differ from other SIP calculators
Most Indian SIP calculators convert your annual rate to a monthly one by dividing by 12. That quietly turns a stated 12% into an effective 12.68%, and over 20 years the difference compounds into a materially larger headline figure. We use the true monthly equivalent of 12% instead, so our answer is slightly lower and internally consistent with every other tool on this site.
On the ÷12 basis you would see ₹2.5 Cr instead of ₹2.3 Cr.
What the chart is really showing
The most useful thing on this page is not the headline number. It is the point on the bar chart where the light blue band — growth — overtakes the dark navy band, which is your own money.
For the first several years, almost everything you see is simply what you deposited. Compounding is doing very little, and this is precisely when most people conclude it is not working and stop. Then the proportions invert, and in the final third of a long SIP the majority of the balance is growth on growth. Nothing about the rate changed. Only the amount of time it had to operate on did.
Step-up beats chasing returns
There are two ways to end up with more: earn a higher return or invest more. The first is largely outside your control and mostly a matter of luck dressed up as skill. The second is a decision you can make in about a minute.
Turn on the step-up input and try 10%. For most combinations of amount and horizon, an annual 10% increase adds more than two extra percentage points of return would — and it does so without taking on any additional market risk. If your income rises each year and your SIP does not, inflation is quietly shrinking your savings rate.
The number that matters is the real one
A projection of ₹2.5 crore in twenty-five years sounds transformative. At 6% inflation it buys roughly what ₹58 lakh buys today. That is still a meaningful sum, but it is a very different mental picture, and it is the picture you should be planning against.
The "in today's money" figure in the results panel does this conversion for you. When you feed a SIP projection into the retirement corpus calculator, this is why the target corpus looks so large — it is expressed in future rupees, as it has to be.
A note on honesty in SIP calculators
We deliberately produce a slightly lower number than most Indian SIP calculators, and we show you both figures rather than quietly picking the flattering one. The reason is set out in full on our methodology page: dividing an annual rate by 12 inflates it, and over multi-decade horizons that inflation is not trivial. A retirement plan built on the optimistic convention is a plan with a hidden margin of error in the wrong direction.
Frequently asked questions
Why is your SIP figure lower than other calculators?
Because of how the annual rate is converted to a monthly one. Most Indian SIP calculators divide by 12, so a stated 12% becomes 1% a month — which compounds to an effective 12.68% a year. We use the true monthly equivalent of 12%, which is about 0.9489%. Over twenty years the two methods differ by roughly 8%. Ours is the more conservative and internally consistent basis; the results panel shows you the ÷12 figure as well so you can reconcile against any other site.
What return should I assume for a SIP?
Nobody knows. Long-run Indian equity index returns have historically been in the low teens, but any twenty-year period contains stretches of years that are flat or negative. Rather than hunting for the "right" number, run 8%, 10% and 12% and look at the range. If your plan only works at the top of that range, it is not really a plan.
What is a step-up SIP and is it worth it?
A step-up SIP raises your monthly contribution by a set percentage each year, usually in line with your salary. It is the most underrated lever available to most investors: a 10% annual step-up will typically add more to your final corpus than finding an extra two percentage points of return, and unlike return, it is entirely within your control.
When are the contributions assumed to be made?
At the start of each month, which is how a SIP mandate actually executes. That is an annuity-due calculation and gives one extra month of compounding on every instalment compared with an end-of-month assumption.
Does this account for expense ratios, exit loads or tax?
No. The return you enter should be interpreted as a net-of-expenses figure if you want the output to be realistic. Exit loads and capital gains tax apply when you redeem and are not modelled here.
