A Step-up SIP raises the monthly contribution on an annual schedule

The ArthaSiddhi Step-up SIP Calculator starts with a monthly contribution, increases it after each completed 12-month block by the entered step-up percentage, and projects the result at one entered annual return.

Use the Step-up SIP Calculator to see how changing the contribution schedule changes the projection.

The projection uses four assumptions

Contributions are modeled at the beginning of each month. The annual step-up changes the contribution only after the prior 12-month block has completed.

  • Starting monthly investment
  • Annual step-up percentage
  • Entered annual return assumption
  • Whole-year investment duration

Engine-derived example: ₹5,000 starting contribution, 10% annual step-up and 12% entered return

For 10 years, the engine produces total invested capital of ₹9,56,245.48, projected growth of ₹7,30,917.66, and a projected future value of ₹16,87,163.13. The final modeled monthly contribution is ₹11,789.74.

More projected value can reflect more contributed capital as well as growth

A Step-up SIP changes the amount invested over time. A higher projected value therefore cannot be attributed only to superior investment performance: part of the difference may come from the additional contributions themselves.

For the exact monthly sequence, read How Step-up SIP Is Calculated. The existing Fixed SIP vs Step-up SIP article remains the comparison guide.

This is a projection, not a promise about future value

The calculator holds the entered return constant, uses its beginning-of-month contribution convention and applies a fixed annual step-up schedule. Actual returns, contribution dates and investor decisions can differ.

Review those assumptions in Step-up SIP Projection Assumptions.

Frequently asked questions

Does a Step-up SIP increase the return rate each year?

No. The calculator increases the contribution by the entered annual step-up percentage. The entered annual return remains the projection assumption throughout.

Does a higher projected value mean better investment performance?

Not necessarily. A Step-up SIP also contributes more capital over time, so the result reflects both contributions and modeled growth.

Are Step-up SIP projections guaranteed?

No. The result is an assumption-based projection and is not a guaranteed future value or return.
