Step-up SIP calculator
A SIP that rises every year as your income does.
Quick answer
A step-up SIP raises the monthly investment by a fixed percentage every year, so it grows with your income. Formula: Year 1 monthly amount = P; year k amount = P × (1 + step)^(k − 1). ₹10,000 a month, raised 10% every year at 12% for 10 years, grows to about ₹33,74,326.

How is a step-up SIP calculated?
Salaries usually grow, so a SIP that grows with them is realistic. A 10% yearly step-up is a common choice.
The first years carry little money, so most of the gain comes from the later, larger instalments. The table shows the investment rising each year.
Compare with the plain SIP calculator to see what the step-up adds.
What is the formula for a step-up SIP?
- Year 1 monthly amount = P; year k amount = P × (1 + step)^(k − 1)
- Each month: balance = (balance + amount) × (1 + i), with i = yearly return ÷ 12 ÷ 100
Can you show a worked example of a step-up SIP?
₹10,000 a month raised 10% each year for 10 years at 12%: you invest ₹19,12,491 in total and reach ₹33,74,326. A flat ₹10,000 SIP would reach ₹23,23,391.

Common questions
What step-up percentage should I use?
Match it to how fast your income grows. Even 5% a year adds a noticeable amount over a decade.
Does the step-up apply every month?
No. The amount is flat within a year and rises once, at the start of each new year.
Can I step up in rupees instead of percent?
This calculator uses a percentage. A fixed rupee step is not supported.
Do all funds allow a step-up?
Many mutual fund platforms offer a top-up SIP. Check with yours.
