Cost of Delay Calculator
Waiting five years to start a SIP doesn’t just mean five fewer years of contributions, it means losing the five years your money would have compounded the longest. This calculator shows exactly what that delay costs in final corpus, and the higher monthly SIP you’d need afterward just to catch back up to where you’d have been.
What is a Cost of Delay Calculator?
A cost of delay calculator quantifies the rupee cost of postponing a SIP by a chosen number of years, comparing the final corpus if you start today against the corpus if you wait. It also calculates a ‘catch-up SIP‘, the higher monthly amount you’d need to invest after the delay to still reach the same target by your original goal date.
Whose Delay Is Actually Costing the Family the Most?
This calculator models one person’s delay decision in isolation. In families saving toward a shared goal, a child’s education, a joint retirement plan, it’s common for each person to assume someone else has already started, or that a few years’ delay won’t matter much. Run individually, this calculator can’t show which family member’s delay is actually the most expensive one to fix first.

It's the higher monthly SIP amount you'd need to invest after your delay to still reach the same final corpus by your original goal date. It rises steeply because you now have fewer years left to compound.
No. It assumes a steady, uninterrupted return for simplicity. The page's own disclaimer notes that real markets are volatile and actual returns vary year to year, and that this isn't investment advice.
