Retirement Calculator not working? Here's how to fix it

Most issues with the Retirement 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 required corpus looks impossibly high

Check your inflation rate. A 7% inflation rate over 25-30 years compounds expenses dramatically. Try 5-6% if you expect lower personal inflation, or accept that medical and lifestyle inflation often exceed the headline CPI.

3. The projected corpus looks too low

Verify your monthly investment. You must sum ALL monthly contributions — EPF (employee + employer), PPF, NPS, SIPs, and any other systematic investments. Missing even one account can make the projection look far short.

4. The shortfall seems wrong

Confirm your expected return. If you entered 12% but hold a balanced portfolio, the real return may be closer to 9-10%. Lower the return assumption and re-check. The tool compounds returns annually, so small changes compound over 20-30 years.

5. The result does not match my financial planner's number

Planners may use different corpus multiples (30x vs 25x), factor in pension income, rental income, or stepwise expense changes in retirement. The calculator uses a standard 25-30x multiple on inflated annual expenses. Treat it as a baseline, not a comprehensive financial plan.

Verdict

Nine out of ten issues with the Retirement Calculator are solved by including all monthly investments, using a realistic return, and understanding the 25-30x corpus multiple.

Frequently asked questions

Why is my required corpus so high?

Inflation compounds expenses over 20-30 years. At 7% inflation, expenses quadruple in ~20 years. The 25-30x multiple on inflated annual expenses creates a large target.

Why does my projected corpus look low?

You likely missed some monthly contributions. Sum EPF (both shares), PPF, NPS, SIPs, and any other regular investments as your monthly investment input.

Why does my shortfall differ from my planner's?

Planners may include pension/rental income, use different corpus multiples, or model phased expenses. The calculator gives a standard baseline estimate.
