About the Retirement Calculator

Retirement planning in India is a three-variable problem: how long you'll live after retiring, how inflation erodes your money's value, and what return your corpus generates in retirement.

This calculator uses a two-phase model. Pre-retirement: you invest at a higher-return portfolio (typically equity-heavy). Post-retirement: you shift to lower-risk (debt-heavy) and withdraw gradually, assuming annual inflation in expenses.

The monthly SIP shown is what you'd need to invest from today to hit your retirement corpus. Rising inflation (from 6% to 7%) can increase required SIP by 30–40% — it's the single biggest lever.

Retirement — Frequently asked questions

It projects your future monthly expense using inflation, computes the corpus needed to sustain that expense for your retirement duration using real return (post-retirement return minus inflation), then calculates the monthly SIP needed to build that corpus.
