SWP Calculator

The SWP calculator grows the corpus at a monthly rate, deducts each month's withdrawal, raises the withdrawal by your chosen percentage every year and reports the remaining corpus, total withdrawals, months sustained and the remaining corpus in today's money.

SWP Calculator: what it calculates.

A Systematic Withdrawal Plan takes a fixed amount out of a mutual fund corpus every month while the rest stays invested. It is often used to draw a regular income in retirement. This calculator shows whether a corpus can sustain your withdrawals under an assumed return, and what may be left at the end.

The SWP calculator grows the corpus at a monthly rate, deducts each month's withdrawal, raises the withdrawal by your chosen percentage every year and reports the remaining corpus, total withdrawals, months sustained and the remaining corpus in today's money.

How the calculation works.

Corpus next month = Corpus × (1 + r/12) − Withdrawal
  • r is the assumed annual return, divided by 12 for the monthly rate.
  • Each month's growth is added before that month's withdrawal is taken.
  • The withdrawal increases by the annual step-up at the start of each new year.
  • If the corpus runs out, withdrawals stop and the months sustained are shown.

Worked example. A ₹50 lakh corpus with a ₹20,000 monthly withdrawal rising 5% a year, at an assumed 9% return for 20 years, pays out about ₹79.4 lakh in total and still leaves about ₹1.09 crore. At 6% inflation, that remaining corpus is worth roughly ₹33.9 lakh in today's money.

How to use it

  1. 1.Enter the corpus you plan to withdraw from.
  2. 2.Enter the monthly withdrawal and any yearly increase to keep pace with expenses.
  3. 3.Set a cautious return assumption and the number of years.
  4. 4.Check the months sustained and test a lower return before relying on the plan.

What it helps with

  • Shows whether withdrawals outlast the chosen period.
  • Models rising withdrawals instead of a flat amount.
  • Shows the remaining corpus in today's money.
  • Makes the effect of a lower return easy to test.

What it does not include

  • Returns are market-linked; a poor early sequence of returns can deplete a corpus faster than a steady average suggests.
  • Capital gains tax on each withdrawal, exit loads and expense ratios are not modelled.
  • A constant return is an assumption, not a forecast.
  • The result is an estimate and does not recommend a fund or withdrawal rate.

Common questions.

What is a SWP Calculator?

It is an educational tool that applies the disclosed systematic withdrawal method to the assumptions you enter.

Are the results guaranteed?

No. Results are estimates, not forecasts, approvals, quotations or guarantees.

Why should I change the assumptions?

Testing conservative and optimistic inputs exposes uncertainty instead of hiding it behind one number.

Does it include tax and fees?

Only when a tax or fee is shown as an explicit input or result. Otherwise it is excluded.

How accurate is the calculator?

The mathematics follows the stated methodology, while real outcomes depend on rates, timing, rules, fees and circumstances.

Can I use this result as financial advice?

No. Use it for education and scenario comparison, then verify decisions with official documents or a qualified professional.

Why is inflation shown?

Inflation translates a future amount into approximate present-day purchasing power. The default 6% is editable and is not a forecast.

How often should I recalculate?

Recalculate when rates, income, contributions, rules, goals or repayment terms change.

Can the result differ from a bank or platform?

Yes. Institutions may use different compounding dates, rounding, charges and eligibility rules.

Is my data uploaded?

No. Calculations run locally in your browser and the input values are not sent to a calculation server.
