Retirement Calculator

Work out the corpus your retirement actually needs after inflation, and the monthly saving that builds it.

Your ₹60,000 of monthly expenses today becomes ₹3,06,701 at 60 after 6% inflation. Existing savings grow to ₹1.19 Cr, leaving ₹6.97 Cr to build — which needs ₹25,260 invested every month from now.

About the Retirement Calculator

Retirement planning fails in one specific way: people plan against today's expenses. At 6% inflation, ₹60,000 a month becomes about ₹3.2 lakh a month in twenty-eight years, and a corpus sized for the smaller number runs out early.

This calculator works in real terms. It inflates your expenses to your retirement date, then computes the corpus that can fund a rising withdrawal for your full life expectancy, nets off what you have already saved, and solves for the monthly investment that closes the gap.

The formula

Corpus = annual expense at retirement × [1 − (1 + real rate)^−n] ÷ real rate, where real rate = (1+post-retirement return) ÷ (1+inflation) − 1
Real rateReturn net of inflation, which is what preserves purchasing power
nYears in retirement

Using the real rate means the withdrawal keeps rising with inflation for the whole of retirement.

Things worth knowing

1
Starting at 30 rather than 40 typically halves the monthly amount required.
2
Keep three to five years of expenses in debt at retirement so a market fall never forces you to sell equity.
3
Do not count your home as retirement corpus unless you genuinely intend to sell or reverse-mortgage it.

Frequently asked questions

A common shorthand is 25–30 times your annual expenses at retirement, which supports a 3–4% withdrawal rate. The calculator above is more precise because it uses your actual inflation and return assumptions and your life expectancy.

Around 3.5–4% of the corpus in the first year, rising with inflation thereafter. Higher rates carry a real risk of exhausting the corpus over a thirty-year retirement.

Yes — put their projected value into the existing savings field, or model them separately with the EPF and NPS calculators and add the results.
