Step-Up SIP Calculator

A regular SIP invests the same amount every month for the entire tenure. A step-up SIP — also called a top-up SIP — increases that monthly amount by a fixed percentage each year. The logic is simple: your income generally rises over your career, so your investing should rise with it. A 10% annual step-up roughly tracks typical salary growth, letting you channel more into the market each year without ever feeling a sudden squeeze on your budget.

The impact on your final corpus is dramatic because the extra contributions arrive while there's still plenty of time for them to compound. Each year's increase doesn't just add a little more principal — it adds principal that then grows for the remaining years of the plan. The year-by-year table below makes this visible: you can watch the monthly SIP climb, the yearly investment rise, and the corpus accelerate. Over a 20- or 25-year horizon, a modest step-up frequently turns into tens of lakhs of additional wealth versus a flat SIP that started at the same amount.

To put a step-up SIP into practice, most fund houses and apps let you set an automatic annual top-up when you start the SIP, so you don't have to remember to raise it each year. Pick a step-up percentage you can sustain — aligning it with your expected appraisal is a good rule of thumb — and link the plan to a concrete goal like retirement or a child's education. As always, the return figure here is an assumption, not a guarantee: equity markets are volatile year to year, so model a realistic long-run rate and stay invested through the dips, which are precisely the periods that lift your eventual returns.
