Retirement planning is really two calculations stacked together. First, what will your current lifestyle cost by the time you stop working? Second, how large a pot funds that inflated expense for the rest of your life? This tool runs both, then works backwards to the monthly investment that gets you there — and shows the whole path in two tables: the years you spend building the corpus, and the years you spend living off it.
It works anywhere. Whether you are building an EPF and NPS corpus in India, a 401(k) or IRA in the United States, a pension and ISA in the UK, an RRSP or TFSA in Canada, superannuation in Australia or CPF in Singapore, the underlying arithmetic is identical — only the wrapper and the tax treatment differ. Pick your country from the header to see the numbers in your own currency.
Phase 1 — building the corpus. Year by year, with your age alongside, showing what you have contributed and what growth has added. This is the part most calculators stop at.
Phase 2 — living off it. For every year of retirement: the monthly income the corpus pays you, rising with inflation, and what is left at the end of that year. The final row is the number people actually want — what is left when I am done. If the money runs out before your horizon, the tool says so plainly and names the year.
Why does the required monthly amount look so large? Because it is honest about inflation. ₹50,000 of monthly expenses today is roughly ₹1.6 lakh a month after twenty years at 6% — and the same 3.2× multiple applies to $5,000 or £5,000. Any calculator that ignores this understates the target badly.
India. EPF and NPS are the statutory pillars, usually topped up with mutual fund SIPs. Model them precisely in the EPF and NPS calculators, then put the result into the existing savings field here.
United States. A 401(k) with employer match first, then a Roth or traditional IRA. Employer matching is the closest thing to free money in personal finance — count it in your monthly contribution.
United Kingdom. A workplace pension with employer contributions, plus a Stocks & Shares ISA for money you may want before pension age.
Canada. RRSP for the tax deduction now, TFSA for tax-free growth and withdrawals later. Most people use both.
Australia. Superannuation is compulsory, with employer contributions set by law; salary sacrifice adds to it.
Singapore and the Gulf. CPF in Singapore, and in the UAE and Saudi Arabia largely self-directed savings, since there is no compulsory pension for most expatriate workers — which makes planning like this more important, not less.
Should the return be lower after retirement? Yes — most people shift towards bonds and safer assets as they stop earning. That is why pre- and post-retirement returns are separate inputs here.
How long should I plan for? Longer than you expect. Planning to 85 when you live to 92 is the failure mode this calculator is built to expose — set the retirement years generously and watch the final row of the second table.
What if the plan already has enough? The result says so, and the withdrawal table shows the surplus still sitting there at the end rather than pretending it lands at exactly zero.
Is tax included? Only for India, where we model the rules. Everywhere else the figures are pre-tax, because a wrong tax number is worse than none.
