For the first 12 months, the monthly SIP is P. At month 13, the contribution is stepped up by S%. Each increment compounds at the periodic monthly rate for the remaining duration of the horizon.
Yearly Monthly Contribution = P × (1 + S)^(Year - 1)Variables in Formula:

Common Mistakes to Avoid
⚠ Overcommitting to an unsustainable step-up rate
A 20% annual step-up looks great in simulations, but if salary hikes slow down, you may be forced to stop the SIP entirely. Stick to a sustainable 5% to 10%.
⚠ Waiting until year-end to deploy raises
Most Indian mutual fund houses allow automated annual step-up mandates. Automating it prevents you from spending the hike before investing.
⚠ Forgetting to scale emergency reserves
As your monthly investments and standard of living expand, your liquid 3–6 month emergency fund must also be topped up proportionally.
