SWP Calculator — how long will the corpus last?

A Systematic Withdrawal Plan takes a fixed amount out of an invested corpus every month. This calculator shows whether the corpus survives the period you choose at an assumed return — and if not, when it runs out.

How the SWP Calculator works

Month by month: Balance = Balance × (1 + i) − W, where i is the assumed monthly return (annual ÷ 12 ÷ 100) and W the monthly withdrawal. If the balance cannot cover a withdrawal, the corpus is exhausted in that month.

The same rule tells you the sustainable withdrawal: any amount below Corpus × i leaves the corpus growing.

Worked example

A corpus of 5,000,000, with 30,000 withdrawn every month, assumed 8% a year, over 20 years:

Monthly return on 5,000,000	33,333
Total withdrawn	7,200,000
Balance after 20 years	6,963,401

Because 30,000 is below the first month's return, about 6,963,401 is still left after 20 years at that assumed rate.

The arithmetic is the same in any currency; the calculator shows results in the currency you pick.

Frequently asked questions

Does the SWP calculator include tax or inflation?

No. It uses a constant assumed return and a fixed withdrawal. Real returns vary year to year, and withdrawals from mutual funds may attract capital-gains tax.
