Understand the calculation

What is a SIP Cost of Delay Calculator?

See the corpus lost by starting later and the SIP needed to catch up. Keep the goal date fixed. Missed contributions and foregone investment growth are reported separately.

Use the inputs that describe your actual situation. Change one assumption at a time, compare the results, and read the scope note alongside the number. The tool calculates a stated scenario; it does not decide whether an investment, policy or tax treatment is suitable for you.

Method and assumptions

Gap = start-now corpus − delayed corpus at the same goal date

Keep the goal date fixed. Missed contributions and foregone investment growth are reported separately.

Read the result with these boundaries

Keep the goal date fixed. Missed contributions and foregone investment growth are reported separately.

Check the inputs before acting

Confirm actual costs, dates, eligible amounts and product terms from your records. Compare a conservative case and an adverse case rather than relying on the default inputs. A result can change substantially when return, tax, contribution or cost assumptions change.
