Withdrawal at the beginning of each month. What remains earns a nominal annual return, compounded monthly. No expenses and no tax.

How this is calculated
- Step 1
Withdraw first
The fixed amount comes out at the start of the month.
- Step 2
The rest earns
Whatever is left compounds for that month.
- Step 3
It can run out
If the balance cannot cover a withdrawal, the page stops.
Lump sum minus a beginning-of-month withdrawal
B = P(1 + i)^n − W × (((1 + i)^n − 1) ÷ i) × (1 + i)
| P | Starting lump sum. |
|---|---|
| W | Amount withdrawn at the start of each month. |
| i | Monthly rate: annual return divided by 12. |
| n | Number of months, or fewer if the balance hits zero. |
The withdrawal is taken before that month’s growth, the same beginning-of-month timing the SIP calculator uses for deposits.
If a withdrawal would be larger than the balance, only the balance is paid and the plan stops. The page does not show a negative corpus.
The rate is constant and before tax or fund expenses. A withdrawal plan that lasts here can still fail if the return is uneven.
Worked examples
Loading an example fills the tool and scrolls you back to the result. Money examples stay in US dollars on the page. The symbol you picked changes; the numbers do not convert.
A corpus that runs out
Start with $100,000.00. Withdraw $5,000.00 at the start of each month, at 4% a year, for 10 years.
The balance reaches zero after 21 monthly withdrawals. Withdrawn $103,307.05. Growth $3,307.05.
1,000 a month from 250,000 at 7%
Start with $250,000.00. Withdraw $1,000.00 at the start of each month, at 7% a year, for 20 years.
Balance left $485,719.31. Withdrawn $240,000.00. Growth $475,719.31.

What does SWP mean here?
A systematic withdrawal plan: the same amount taken out of a lump sum every month. It is the reverse of a SIP. The page does not know which fund you hold.
Why might the balance still grow?
When the monthly return on what is left is larger than the withdrawal, the corpus rises even while you take income. Lower the rate or raise the withdrawal to see the other case.
What happens when the money runs out?
The last payment is whatever is left, including a partial month, and later months pay nothing. The result names how many withdrawals were made.
Is this a retirement forecast?
No. Markets do not pay a flat monthly rate, and this does not model inflation, tax, or a required minimum distribution. Use it to compare a withdrawal with a return you are willing to assume.
