Introducing the Step-up SIP Calculator — Raise Contributions With Income

We shipped a free step-up SIP calculator that models annual SIP increases and compares corpus vs a flat SIP. Here’s how to use it.

Your salary rarely stays fixed for a decade. Your SIP shouldn’t have to either.

Today we’re shipping a Step-up SIP Calculator — enter a starting monthly amount, an annual step-up %, expected return, and tenure. Instantly see corpus, cash invested, final monthly SIP, and how much extra you get versus never stepping up.

What it does

  • Starting monthly SIP — year-one instalment
  • Annual step-up % — raise every 12 months (presets: 0%, 5%, 10%, 15%, 20%)
  • Expected return + years — same assumptions as our flat SIP tool
  • Vs flat SIP — same start amount with 0% step-up, for an honest delta
  • Year table — monthly amount and corpus at each year-end (when tenure ≤ 15)

When to use it

  • You want SIP to grow with raises
  • You’re comparing “₹5k forever” vs “₹5k with 10% yearly top-up”
  • You’re planning education or a house deposit over a long runway

For a fixed monthly amount only, keep using the SIP Calculator.

Educational estimates only — not financial advice. Returns are assumptions; markets and taxes can differ.
