What does this retirement calculator tell you?
This retirement calculator turns your age, expenses, savings and income into five numbers that describe whether your current plan is on track to fund retirement in India.
Corpus required
The total amount needed at your retirement age to cover expenses, healthcare and any legacy target for the rest of your planning age.
Projected savings
What your existing investments and monthly contributions are on track to become by your retirement age, at the returns you enter.
Funding gap
The difference between the required corpus and the projected corpus, shown as a shortfall or a surplus.
Required investment
The extra amount you would need to invest each month, starting now, to close a shortfall by your retirement age.
Corpus survival
The age up to which your projected corpus is estimated to support your withdrawals, given your assumptions.
How this retirement readiness calculator checks if you are on track
The calculator compares the corpus you are likely to build by retirement with the corpus you may need from retirement age to your planning age. It then converts that comparison into a readiness percentage and a funding gap or surplus.
A corpus calculator shows "how much do I need?" This retirement readiness calculator also checks whether your current savings path can reach that number.
How to use the retirement calculator
The calculator follows five stages, in the same order as the steps on screen.
Enter retirement details
Current age, planned retirement age, and the age up to which you want income to last.
Estimate retirement expenses
Monthly household spending today, and how much of it is expected to continue after retirement.
Add savings and investments
Existing EPF, PPF, NPS, mutual funds and other holdings, plus your ongoing monthly investment.
Add pension and other income
Pension, rental income and any consulting or other recurring income expected after retirement.
Review the retirement gap
See the funded percentage, required corpus, projected corpus and the monthly action needed, if any.
Retirement Example: Meet Priya
Priya is 35 years old, spends Rs 1,00,000 a month, and plans to retire at 60. The calculator tells her the retirement corpus she would need at 60.
Step 1: Her required corpus
She enters her monthly expenses, retirement age, planning age and the calculator's default inflation, return and healthcare assumptions. The calculator tells her she needs ₹8.88 Cr to fund her expenses from 60 to her planning age of 80.
Step 2: Her current progress
Priya has ₹25 lakh invested, adds ₹40,000 a month with an annual step-up, and assumes an 11% return before retirement and an 8% return after. The calculator projects her retirement corpus at ₹11.1 Cr, which is 125% of what she needs, a surplus of ₹2.22 Cr.
If there is a shortfall, she can increase her monthly investment, review her return assumptions, delay retirement, or reduce planned expenses. Since Priya has a surplus, her plan is on track, and the projected corpus is estimated to last until about age 87, past her planning age of 80. The exact result depends on the return, inflation, healthcare, pension, EPF, NPS and other income assumptions entered.
How much retirement corpus do you need?
Six factors decide the number, and changing any one of them moves the result.
Lifestyle costs
What you spend today, and the share of it expected to continue, rise or stop after retirement.
Inflation
The rate at which expenses grow before retirement, and again, separately, during retirement.
Retirement duration
The years between your retirement age and your planning age, itself an assumption about life expectancy.
Healthcare
An additional monthly provision at retirement, since medical costs typically inflate faster than general expenses.
Regular income
Pension, rental or other income that reduces how much your investments need to fund each year.
Legacy preference
Whether you want the corpus to end at zero, stay intact, or leave a fixed amount behind.
How the retirement corpus is calculated
The calculation runs in two phases: building the corpus until retirement, then drawing it down after.
Accumulation phase, before retirement
Existing investments grow at their own expected return, and the monthly contribution is added and compounds alongside them. The contribution itself can rise every year by a step-up percentage you set.
See the formula
Opening balance + investment growth + that year's contribution = closing balance
This repeats every year until retirement, with contributions optionally stepping up annually.
Withdrawal phase, during retirement
The corpus is drawn down every year to cover expenses, net of pension, rental or other income, while what remains keeps growing at your assumed post-retirement return.
See the formula
Opening corpus + investment growth - that year's net expense = closing corpus
Required corpus works backwards from this. It is the starting amount for which this year-by-year calculation reaches your target ending balance, zero, your original corpus, or a chosen legacy amount, by your planning age.
Why your retirement corpus must account for inflation
Inflation can be the largest driver of the required corpus, larger in effect than many return assumptions.
The calculator applies inflation separately: general inflation before and during retirement, and a distinct healthcare inflation rate for medical costs. Using today's expense figure without inflation can understate the required corpus over a long working period.
What counts as retirement income?
Retirement income is any regular inflow that reduces how much your invested corpus needs to cover. It is not the corpus itself.
Pension
A regular payment from an employer scheme or the National Pension System, starting at retirement and continuing for life.
EPS
The Employees' Pension Scheme component built into EPF contributions, paid as a separate monthly pension from retirement.
Annuity
Converts a lump sum or accumulated contributions into regular payments, so enter it as an income stream instead of spendable corpus.
Rental income
Regular rent from property, entered with the age it starts and whether it continues for life or a fixed period.
Consulting income
Part-time work, consulting or a spouse's income expected to continue for some years after retirement.
Portfolio withdrawals
Money drawn from the investment corpus itself to cover whatever expenses other income does not meet.
Which assets should you include in your retirement corpus?
Include holdings genuinely earmarked for retirement. Money assigned to another goal belongs in that goal's own plan.
EPF
Employee Provident Fund balance, typically available in full at retirement.
PPF
Public Provident Fund balance, a long-term, government-backed retirement holding.
NPS
National Pension System corpus. A portion is required to be annuitised at exit under PFRDA rules, the rest is available as a lump sum.
Mutual funds
Equity, debt or hybrid mutual fund holdings allocated to retirement.
Fixed-income investments
Fixed deposits, bonds and similar instruments held for retirement.
Retirement policies
Pension plans or endowment-style policies bought specifically for retirement.
Other retirement assets
Any other holding specifically set aside for this goal, and nothing else.
What does retirement readiness mean?
The "Retirement funded" percentage this calculator shows is a ratio, not a rating.
It divides your projected corpus by your required corpus and multiplies by 100. A figure at or above 100% means the current plan is on track under the assumptions entered. A lower figure shows a gap. The ratio depends on the return, inflation, expense and income assumptions you provide, so changing any one of them can move the percentage up or down. Use it as a planning signal to review periodically, not a fixed or certified outcome.
What if your retirement plan shows a shortfall?
If the result shows a shortfall, review these adjustments in order.
- Increase retirement investment. Raising the monthly contribution directly reduces or closes the gap for the same retirement age and lifestyle assumptions.
- Step up contributions annually. An annual percentage increase can close a similar gap from a lower starting amount than a flat contribution.
- Review the planned retirement age. Retiring a little later shortens the payout period and extends the years available to invest, both of which reduce the required corpus.
- Review retirement lifestyle assumptions. A lower continuation percentage on discretionary expenses reduces the future expense the corpus needs to cover.
- Identify retirement income sources. Pension, rental or other income directly reduces how much the investment corpus alone has to fund.
- Review investment allocation. The pre-retirement and post-retirement return assumptions have a large effect on both sides of the gap.
- Recalculate periodically. Incomes, expenses, returns and life plans change, so check the gap again at least once a year.
Retirement calculator versus FIRE calculator
This calculator tests planned retirement readiness: are your current savings, EPF, NPS, pension, income and investments enough for the retirement age you choose? A FIRE calculator estimates early financial independence: what corpus makes work optional sooner?
| Retirement calculator | FIRE calculator |
|---|---|
| Tests whether you are on track for a planned retirement age | Estimates the early retirement or financial independence number |
| Includes EPF, NPS, pension, rental income and other retirement income | Primarily focuses on corpus-funded independence |
| Shows readiness %, funding gap, extra monthly investment and corpus survival | Centres on the FIRE number and withdrawal-rate assumptions |
| Useful for conventional retirement planning and retirement readiness checks | Useful when the main question is when work can become optional |

Important assumptions and limitations
Every number on this page is a projection built on the assumptions entered, not a forecast.
- Returns are not guaranteed. Actual investment performance can be higher or lower than the rate entered, in any given year.
- Inflation may differ from the rate assumed, before and during retirement, and healthcare inflation in particular is hard to predict precisely.
- Tax treatment of withdrawals, pensions and annuities may change over the years this plan covers.
- Expenses may change in ways this year's inputs cannot anticipate, in either direction.
- Life expectancy, and therefore the true planning age, is uncertain for any individual.
- This calculator is illustrative and not personalised investment advice.
- Review results periodically, since assumptions can change across income, expenses, returns and retirement age.
