Retirement Withdrawal Rate Calculator
Model how long your retirement corpus might last: set spending as a first-year rupee amount or as a percentage of starting corpus, inflate withdrawals and pension together, apply a blended portfolio return from your equity and debt mix, and see when the balance could hit zero relative to your assumed life expectancy.
Ages and horizon
Withdrawals stop at this age in the model: 25 years in retirement.
Withdrawal style
First-year gross withdrawal: about ₹8,00,000 before pension offset.
Portfolio returns (annual, nominal)
Debt allocation: 55% · Blended return used in simulation: 7.8%
Grows with the same inflation rate as spending. Only the gap is withdrawn from your corpus.
Through planning horizon
Age 85corpus still positive
Years drawn from corpus (simulated)
25
Effective year-1 rate on corpus
4%
Corpus at end of horizon
₹3,09,23,161
Year 1 cash need from investments: ₹8,00,000 gross need ₹8,00,000 minus pension ₹0.
On these smooth-return assumptions the corpus may still show ₹3,09,23,161 at age 85.

Educational simulation only: constant annual returns, no taxes or fees, no market volatility, and no change in asset mix over time. Use alongside your real cash-flow and tax planning.
Retirement withdrawal planning and safe withdrawal rates
After you stop earning a salary, your retirement corpus decumulation phase begins: money leaves the portfolio for rent, healthcare, travel, and daily costs. A retirement withdrawal rate describes how much you take relative to your nest egg—often as a percentage in the first year—and whether that spending can rise with inflation. Planners also stress-test longevity: outliving a too-small pool is a real risk as life spans stretch. This page helps you translate assumptions about returns, allocation, pension, and spending into a simple timeline: roughly when the illustrated balance might reach zero, or how much might remain at the end of a chosen horizon.
What this simulator is doing
Each simulated year applies a blended return to the balance (equity weight × equity return + debt weight × debt return). Gross spending in rupees grows by your inflation input from the first-year budget you set—or from the initial percentage of the starting corpus. If you add pension or rent-style income, it grows at the same inflation rate, and only the shortfall is withdrawn from investments. The loop stops if the balance hits zero or if you reach your planning life-expectancy age without exhausting the corpus.

Frequently asked questions
What is a retirement withdrawal rate?
It is the relationship between what you plan to spend from investments and the size of your portfolio, most often quoted as the first year's withdrawal divided by starting corpus. You can enter that either directly as a percentage or as a rupee annual budget; the tool shows the implied rate when you choose rupees.
How does this calculator estimate how long money lasts?
It performs a discrete year-by-year projection: grow the balance by the blended return, subtract the net withdrawal after pension, inflate both spending and pension by the same rate, and repeat until the balance is gone or the life-expectancy horizon ends.
Fixed rupee withdrawal versus percent of corpus—what changes?
Fixed rupees matches a budget line item you already think in. Percent of starting corpus matches how many articles discuss a rule like withdrawing four rupees per hundred in year one and then indexing spending to inflation; it does not recompute the percentage against the remaining balance each year in this implementation.
Why separate equity and debt returns?
Retirees often hold both. Weighting two return assumptions by your equity share is a transparent way to approximate a static mix. Real life adds rebalancing rules, fees, and volatile sequences this sheet cannot capture.
How should I use pension, rent, or annuity income?
Enter the annual amount you expect in the first retirement year. If it moves with prices in your mental model, keeping it tied to the same inflation slider is reasonable for a first pass. Only the gap versus spending drains the corpus.
Does a 4% initial rate mean I am safe?
Academic and practitioner debate continues, especially for long retirements, high valuations, and different countries. Use 4%—or any figure—as a starting scenario, then stress-test lower returns, higher inflation, and longer life.
Are taxes and mutual fund expenses included?
No. Net real spending power after capital gains tax, dividend rules, TDS, and expense ratios can differ materially from the gross flows modeled here.
How does this differ from the FIRE calculator?
The FIRE page focuses on multiples of expenses before retirement. This page assumes you already have a corpus at retirement and asks how long a given withdrawal policy might last under return and inflation assumptions.
Is this tool free?
Yes. It is intended for education and scenario planning, not as investment, legal, or tax advice.
