SIP Calculator not working? Here's how to fix it
Most issues with the SIP Calculator are small and fixable in seconds. Work through these in order.
1. The tool won't load
Reload the page or open it in a fresh tab. If an extension blocks scripts, try private (incognito) mode — the calculator needs JavaScript, which is on by default in every modern browser.
2. The growth looks unrealistically high
The result depends heavily on the assumed return. If the number seems too big, you are likely using a return above reality. Drop the annual return to a more conservative level like 10-12% for equity funds.
3. The corpus looks too small
Check the time horizon. Compounding needs years to become powerful — a 5-year SIP looks very different from a 25-year one. Increase the horizon or the monthly amount.
4. The invested amount seems wrong
Verify your monthly contribution and the number of years. The total invested should equal the monthly amount multiplied by the number of months in the period. If it does not match, recheck both inputs.
5. The projection does not match your actual fund
A SIP calculator projects an assumed average return; real mutual fund returns fluctuate year to year. Your actual corpus depends on the market, so treat the result as a planning estimate, not a guarantee.
Verdict
Nine out of ten issues with the SIP Calculator are solved by using a realistic return and checking the monthly amount and horizon.
