Step by step

Calculating it yourself

Step 1

Set the monthly amount you can commit to without interruption.

Step 2

Use a return assumption appropriate to the asset class, not the best year you have seen.

Step 3

Choose a horizon of at least seven to ten years for equity-linked plans.

Step 4

Add an annual step-up matching your expected salary growth.

Step 5

Compare the inflation-adjusted figure against the goal you are actually saving for.

Questions

What people ask next

Is SIP better than investing a lump sum?

A lump sum wins on average when markets rise, but a SIP removes timing risk and matches how income actually arrives. Behaviourally, most people stick with a SIP.

What return should I assume?

Use the long-run average for your asset mix and then re-run the model two or three points lower to see how sensitive your goal is.
