Retirement Calculator

Two numbers matter for retirement: the corpus you need on the day you stop working, and the monthly investment that builds it in the years you have left. This calculator sizes both, with your expenses inflated to what they will actually cost by then.

Building the corpus, year by year

From today to age 60. The dashed line is what you put in; the gap above it is compounding, and it is why starting a decade earlier matters more than saving a little more each month.

What is a retirement calculator?

A retirement calculator works out how large a corpus you need at retirement to fund your living expenses for the rest of your life, and then how much you must invest every month between now and then to build it.

It is the hardest of the standard planning calculations because it compounds two long horizons back to back. Your money grows for the twenty or thirty years before retirement, and then has to survive twenty or thirty more while you draw on it — with inflation raising your monthly withdrawal the whole way through.

That second half is where most retirement estimates go wrong. If you need ₹50,000 a month today and retire in 30 years, 6% inflation makes that ₹2,87,175 a month by then — and it keeps climbing through retirement. A corpus sized against today's expenses, or against a fixed withdrawal, runs dry years early.

How the retirement corpus is calculated

The corpus is the present value, at retirement, of a monthly withdrawal that starts at your inflated expense figure and keeps growing with inflation, drawn from a balance that keeps earning your post-retirement return. In other words, a growing annuity.

This calculator solves that growing annuity directly rather than using the common shortcut of a flat withdrawal discounted at return minus inflation. Checked against a month-by-month drawdown simulation, this form lands exactly on zero at your life expectancy; the shortcut over-provisions a 25-year retirement by around 3%.

Corpus = W × [ 1 − ((1+g)/(1+i))^n ] ÷ (i − g) × (1 + i)

W
First monthly withdrawal — today's expense inflated to your retirement date
i
Monthly post-retirement return (annual rate ÷ 12 ÷ 100)
g
Monthly inflation, as (1 + annual inflation)^(1/12) − 1
n
Months in retirement — (life expectancy − retirement age) × 12

Worked example — retiring at 60, ₹50,000 a month today, aged 30

  • Years to retirement = 30, years in retirement = 25 (to age 85)
  • First withdrawal = 50,000 × 1.06^30 = ₹2,87,175 a month
  • Post-retirement return 7% p.a., inflation 6% p.a., n = 300
  • Corpus = ₹7,48,85,443
  • Existing savings ₹5,00,000 grow at 12% to ₹1,49,79,961
  • Shortfall = ₹5,99,05,482, spread over 360 monthly instalments at 12%

Monthly investment needed ≈ ₹16,971

How to use the Finzace retirement calculator

  1. 1Enter your age today and the age you intend to retire. The gap between them is your accumulation phase.
  2. 2Set a life expectancy. Plan long — running out of money at 88 because you assumed 80 is the one planning error that cannot be corrected after the fact.
  3. 3Enter your monthly expenses in today's rupees. Leave out EMIs that will have finished and children's costs that will have ended; add anything retirement adds, particularly health cover.
  4. 4Set inflation. 6% is the usual planning assumption for India, and it is not the place to be optimistic.
  5. 5Set two return rates: a higher one for the accumulation years when you can hold equity, and a lower one for retirement when the portfolio shifts towards fixed income.
  6. 6Enter what you already have — EPF, NPS, mutual funds, anything earmarked for retirement. It compounds alongside and reduces the monthly figure.

Why size retirement before anything else

It is the only major goal with no loan available as a fallback.
Turns an abstract worry into a corpus figure and a monthly instalment.
Prices your expenses at what they will actually cost, not today's cost.
Models the drawdown phase, not just the saving phase.
Shows what a five-year delay costs, in rupees per month.
Credits EPF, NPS and existing investments instead of ignoring them.

What starting later costs you

Same target lifestyle, same retirement age, same assumptions — the only thing that changes is the age at which you start. Note that the required corpus falls as you start later, because there are fewer years of inflation before retirement, and yet the monthly investment rises steeply anyway. That is compounding being taken away from you.

Why two different return rates?

Before retirement you have income, a long horizon and the ability to ride out a bad decade — which is what makes equity risk worth taking. After retirement you are selling assets to eat, and a deep drawdown in the first few years of withdrawals does permanent damage, because you sell units at the bottom to fund living costs and they are never repurchased.

That is why most retirement portfolios shift towards fixed income at or near retirement, and why the calculator asks for a lower post-retirement return. Setting both rates to 12% will produce a comfortable-looking corpus that assumes you keep taking equity risk at 75.

  • Before retirement, with 15+ years to go: 11–13% is a common equity-tilted assumption.
  • After retirement: 6–8%, reflecting a portfolio weighted towards FDs, bonds, SCSS and debt funds.
  • If your post-retirement return is below inflation, the corpus loses purchasing power every year — the calculator flags this.

What this calculator does not include

A retirement projection is a planning tool, not a financial plan. Several things sit deliberately outside it, and each one can move the answer materially.

  • Taxes on withdrawals, which depend on the instrument and the rules at the time.
  • Any pension, annuity or rental income you expect — that reduces the corpus needed, and this calculator assumes none.
  • Lump-sum costs in retirement: a medical event, a home repair, helping a child.
  • Sequence-of-returns risk — a bad first five years of retirement hurts far more than the same returns arriving later.
  • The possibility that you keep earning something after 60, which many people do.

Retirement calculator — frequently asked questions

How much do I need to retire in India?
There is no single number — it depends on your expenses, not your income. As a rough guide, a 30-year-old spending ₹50,000 a month today and retiring at 60 needs a corpus of roughly ₹7.5 crore on standard assumptions (6% inflation, 7% post-retirement return, funding to age 85). Someone spending ₹25,000 a month needs about half that. Enter your own expenses above rather than relying on a rule of thumb.
Is 25 or 30 times annual expenses a good target?
It is a reasonable sanity check, and it comes from the 4% withdrawal rule derived from US market history. It travels imperfectly to India, where inflation has run higher, and it assumes a retirement of about 30 years. Use it to check whether this calculator's answer is in a sensible range, not to replace the calculation.
Should I include my EPF and NPS balance?
Yes — enter the current balance in 'Retirement savings so far'. Note that the calculator grows it at your pre-retirement return, which for an EPF balance earning around 8% is optimistic if you enter 12%. If a large share of your existing corpus sits in EPF, consider setting a blended pre-retirement return rather than a pure equity one.
What life expectancy should I plan for?
Longer than you expect. Indian life expectancy at birth understates it badly for planning purposes — conditional life expectancy for someone who has already reached 60 in good health is considerably higher. Planning to 85 is a common default; 90 is more conservative and costs relatively little at the margin, because the last few years are discounted heavily.
What happens if inflation is higher than I assumed?
The corpus needed rises sharply, because inflation compounds through both phases — it raises the expense you retire on, and it keeps raising the withdrawal for decades afterwards. Moving the assumption from 6% to 7% on the default scenario adds more than ₹3.5 crore to the corpus. If you are uncertain, plan on the higher figure.
Can I retire earlier than 60?
The calculator will tell you what it costs. Early retirement squeezes from both ends: fewer years to accumulate and more years to fund. Drop the retirement age from 60 to 50 in the default scenario and the required monthly investment goes from about ₹21,000 to about ₹55,000 — two and a half times as much, for a corpus that is smaller. It is achievable, but the arithmetic is unforgiving and it needs to start early.
Does this account for a pension or rental income?
No. It assumes the corpus funds your expenses entirely. If you expect a pension, an annuity or rental income, subtract it from your monthly expense figure before entering it — the corpus then only has to fund the gap.

The figures shown are illustrative projections generated from the inputs you enter, not a guarantee of returns. Market-linked investments are subject to market risk; actual returns will vary with market conditions, fund performance, expense ratios, exit loads and applicable taxes.
