Step-Up SIP Calculator
Calculate the corpus your monthly SIP will build when you increase it by a fixed percentage every year — matching how your salary actually grows. Step-up SIP can 2-3x your final corpus over 20 years versus a flat SIP, without you needing to remember to manually raise your contribution.
Year-wise contribution & corpus growth
How your monthly SIP increases each year, the annual contribution that creates, and the running corpus at the end of each year.
| Year | Monthly SIP | This year's contribution | Total invested | Corpus (end of year) |
|---|
Where to start a step-up SIP
Direct mutual fund apps charge zero commission, saving you 1-1.5% annually. Over 20 years that 1% gap eats 15-25% of your corpus — bigger than the step-up benefit itself.

Frequently asked questions
What is a step-up SIP?
A step-up SIP (also called top-up SIP) increases your monthly investment by a fixed percentage every year — usually 5-15% — to match your annual salary growth. It compounds your wealth much faster than a flat SIP because each year you contribute more capital that itself compounds over remaining years.
How much can a 10% annual step-up grow my corpus?
At 12% annual returns over 20 years, a Rs 10,000 monthly SIP grows to about Rs 99 lakh as a flat SIP, but to about Rs 1.95 crore with a 10% annual step-up — nearly double, for the same starting commitment. Try the slider above to see your own numbers.
Is step-up SIP better than regular SIP?
For salaried Indians, yes — step-up SIP matches your investing capacity to your salary growth. A 10% step-up roughly tracks typical annual increments in tier-1 Indian jobs (IT, finance, consulting). The result is a much larger final corpus without you having to remember to manually increase your SIP each year.
How do I activate step-up SIP in my mutual fund?
Most direct mutual fund apps — Zerodha Coin, Groww, Paytm Money, Kuvera, ET Money — offer a step-up toggle when you create an SIP. You set the base amount, the step-up percentage, and the step-up frequency (usually annual). The app handles the increment automatically on your chosen day each year. No paperwork.
What step-up percentage should I choose?
Match your expected annual salary growth. Conservative (5-7%): matches inflation, safer if your income is variable. Standard (10%): matches typical Indian salary increments. Aggressive (15-20%): only if you have high income visibility and strong promotion track. Going higher than your actual salary growth means a rising savings rate over time — good in theory, harder in practice.
Can I pause or modify step-up SIP?
Yes. You can pause your SIP anytime (1-6 months on most direct platforms), modify the step-up percentage, or convert to a flat SIP. There is no exit load or penalty on changing SIP parameters — only the standard mutual fund exit load applies on actual redemptions.
How is step-up SIP corpus calculated?
For each year y from 1 to n: monthly SIP = base × (1 + step-up)^(y-1). For each month within that year, corpus is updated as corpus = (corpus + monthly SIP) × (1 + monthly rate), where monthly rate = annual rate / 12. The calculator iterates month-by-month for accuracy rather than using the closed-form approximation, so the numbers match what mutual fund apps actually show.
How are step-up SIP returns taxed in India?
Step-up SIP is taxed identically to regular SIP. Equity mutual funds: 12.5% LTCG tax on gains above Rs 1.25 lakh per year (after 1-year holding). Debt funds: taxed at slab rate from FY24 onwards. ELSS step-up SIP: 3-year lock-in applies to each instalment separately, including the stepped-up portions.
