There is no single magic number, but for most urban Indians retiring around age 60 in 2026, the corpus works out to roughly 25 to 35 times your expected annual expenses at retirement — often somewhere between ₹4 crore and ₹12 crore, depending on your lifestyle. The exact figure depends on four things: your monthly expenses today, the age you retire, how long you expect to live, and inflation. This guide shows you the method, the assumptions that matter, and a full worked example you can copy using our retirement calculator.
The four numbers that decide your corpus
A retirement corpus is the single lump sum you aim to have on the day you stop earning. Invested sensibly, it should fund your living expenses — rising every year with inflation — until your life expectancy. To estimate it, you only need four inputs:
- Current monthly expenses — what you actually spend now, not what you earn. Strip out EMIs you'll have cleared and add costs that rise in retirement (healthcare, help at home).
- Years to retirement — the gap between your age today and your planned retirement age.
- Inflation — the silent corpus-killer. Indian retail inflation has historically hovered around 5-7%; lifestyle and medical inflation often run higher.
- Life expectancy — how many years the corpus must last. With longer lifespans, planning to age 85-90 is prudent so you don't outlive your money.
How the corpus is actually calculated
The method has three clean steps, and it's exactly what the calculator runs under the hood.
Step 1 — Inflate today's expenses to your retirement year. Money loses purchasing power, so what costs ₹50,000 a month today will cost far more in 30 years.
Expense at retirement = today's expense × (1 + inflation)^years
Step 2 — Size the corpus. Once retired, your corpus stays partly invested and earns a more conservative post-retirement return (typically debt-heavy, around 7%). But your withdrawals also keep rising with inflation. The corpus is the present value of all those inflation-adjusted yearly withdrawals across your retirement years, discounted at a real return (post-retirement return adjusted for inflation):
Real return = (1 + post-retirement return) ÷ (1 + inflation) − 1
Step 3 — Find the monthly SIP. Finally, work out the monthly investment that — compounded at your pre-retirement return (equity-heavy, often assumed around 11-12%) — grows into that corpus by the day you retire.
This is more accurate than the popular "25x rule" (corpus = 25 × annual expenses, derived from a 4% safe-withdrawal rate), because India's higher inflation makes a flat 4% withdrawal optimistic. Use the 25x figure as a quick sanity check, not the final answer.
Worked example: a 30-year-old in 2026
Let's run a realistic case. Meet Priya, 30, who spends ₹50,000 a month today and wants to retire at 60, planning her corpus to last until 85.
| Input | Value |
|---|---|
| Current age | 30 |
| Retirement age | 60 |
| Current monthly expenses | ₹50,000 |
| Assumed inflation | 6% p.a. |
| Return before retirement | ~12% p.a. (equity-heavy) |
| Return after retirement | ~7% p.a. (debt-heavy) |
| Life expectancy | 85 |
Working through the steps:
- Years to retirement: 60 − 30 = 30 years
- Monthly expense at 60: ₹50,000 × (1.06)^30 ≈ ₹2.87 lakh/month (about ₹34.5 lakh a year). This is what 6% inflation does over three decades — the single most eye-opening number in the whole exercise.
- Retirement duration: 85 − 60 = 25 years
- Real return in retirement: (1.07 ÷ 1.06) − 1 ≈ 0.94% — because inflation eats most of the 7% return.
- Corpus needed at 60: present value of 25 years of inflation-rising withdrawals at a ~0.94% real return works out to roughly ₹7.6 crore.
- Monthly SIP from age 30: the investment that compounds at ~12% to reach ₹7.6 crore in 30 years is approximately ₹21,000-22,000 a month.
The headline lesson: a number that looks impossibly large (₹7.6 crore) is reachable with a disciplined SIP of around ₹21,000 a month, because of 30 years of compounding. Start the same plan at 40 instead of 30 and the required SIP roughly triples — time is your biggest lever, not return.

Which accounts build the corpus?
In India, your retirement corpus is usually a blend across tax-efficient and growth vehicles. None of these returns is guaranteed, and market-linked options will fluctuate.
- EPF / VPF — your default workplace corpus; debt-like, EEE-style tax treatment, steady but inflation-sensitive over decades.
- NPS (National Pension System) — equity + debt mix, very low cost, with an extra ₹50,000 deduction under Section 80CCD(1B) over and above 80C (old tax regime). A portion must be annuitised at exit.
- PPF — backed by the government, currently around 7.1% p.a., fully tax-free (EEE), ₹1.5 lakh/year cap, 15-year lock-in with partial withdrawals allowed from year 7; the rate is reset by the government each quarter. Project maturity with the PPF calculator.
- Equity mutual funds / index funds (via SIP) — the main engine for beating inflation over a 20-30 year horizon. ELSS funds also qualify under 80C with the shortest lock-in (3 years). Estimate growth with the SIP calculator.
- Fixed deposits — useful for stability near and during retirement; interest is fully taxable at your slab, with TDS once interest crosses ₹50,000 a year (₹1,00,000 for senior citizens), under the thresholds applicable from FY2025-26.
A common glide path is to stay equity-heavy while young for growth, then gradually shift toward debt and FDs as retirement nears to protect the corpus from a market crash just before you need it.
A few tax points for 2026
Keep these in mind, because taxes shape how much your corpus actually delivers:
- The ₹1.5 lakh Section 80C deduction (covering PPF, ELSS, EPF and more) is available only under the old tax regime — the new regime trades these deductions for lower slab rates.
- The NPS 80CCD(1B) ₹50,000 deduction sits on top of 80C, again under the old regime.
- On equity mutual funds, long-term capital gains are taxed at 12.5% above a ₹1.25 lakh annual exemption, and short-term gains at 20% (2024 rules) — so withdrawing in a staggered, planned way helps manage the bill in retirement.
Mistakes that wreck retirement maths
- Ignoring inflation — planning around today's ₹50,000 instead of tomorrow's ₹2.87 lakh is the most common and most expensive error.
- Underestimating lifespan — building a corpus to 75 when you live to 90 means running out at the most vulnerable time.
- Counting on EPF alone — for most people it covers only a fraction; the calculator deliberately doesn't subtract existing savings, so treat its number as a gross target and adjust down for what you already hold.
- Starting late — every decade you delay roughly doubles or triples the required SIP. The cheapest day to start was yesterday; the second cheapest is today.
Frequently Asked Questions
How much do I need to retire comfortably in India? As a rule of thumb, aim for 25-35 times your expected annual expenses at retirement. For someone spending ₹50,000 a month today and retiring in 30 years, that often lands between ₹6 crore and ₹9 crore once inflation is included. Your exact number depends on lifestyle, retirement age and life expectancy — run it through the retirement calculator.
Is ₹1 crore enough to retire in India? For most urban earners retiring in 20-30 years, ₹1 crore is unlikely to be enough on its own, because inflation pushes annual expenses far higher by then. ₹1 crore may suffice for a very modest lifestyle, a late-life start, or in lower-cost towns — but stress-test it against your inflated expenses rather than assuming it works.
Does the calculator subtract my EPF and existing savings? No. It estimates the total corpus and the SIP to build it from scratch, so the figure is a clean target. If you already hold EPF, NPS or PPF earmarked for retirement, your additional monthly SIP will be lower than the number shown.
How much should I invest each month for retirement? That depends on your target corpus and years left. The retirement calculator converts your corpus into a required monthly SIP directly; broadly, starting in your 20s-early 30s, 15-25% of income into long-term equity investments puts most people on track. Map every goal together in the financial planner to see the full picture.
