$1,000 a month is a 4% starting draw

With no real growth, $300,000 funds 300 month-end payments of $1,000: 25 years. A $2,500 withdrawal would use the same balance in ten years. The first job is to identify which amount the savings must actually cover.

A $2,500 budget need not mean a $2,500 withdrawal

In this example, other spendable income supplies $1,500 of a $2,500 monthly budget. The portfolio supplies the remaining $1,000. Both income figures are chosen assumptions; neither is an estimate of Social Security, pension benefits or take-home pay.

Green is assumed outside income; brass is the portfolio gap. All amounts are monthly and hypothetical.

Three starting rates on $300,000

A 3%, 4% or 5% first-year draw equals $750, $1,000 or $1,250 per month. The columns hold each amount constant in purchasing power.

Final dates include a partial payment when needed. “No depletion” assumes the stated constant growth continues.

What $500 of part-time income changes

Adding $500 of work income reduces the portfolio gap to $500 while that work continues. At zero return, seven years of $500 withdrawals consume $42,000; $1,000 withdrawals consume $84,000. The difference is $42,000 kept in the account before any tax or investment effects.

Give temporary earnings an end date

If the work lasts seven years, do not use the $500 gap for every later year. The zero-growth balance would be $258,000 when that work ends. Returning to a $1,000 monthly draw then funds another 258 payments. A constant-input calculator represents one phase at a time.

Questions about this calculation

Can I retire on $300,000?

The answer depends strongly on the income gap. This page illustrates $300,000 supplying $1,000 monthly alongside $1,500 of assumed outside income. It does not establish that those resources cover your expenses, taxes or retirement horizon.

How much is 5% of $300,000 per month?

Five percent is $15,000 in the first year, equivalent to $1,250 per month. That percentage is an arithmetic starting rate, not a safety recommendation.

Can I count part-time pay after I stop working?

No. In the seven-year example, the withdrawal rises from $500 to $1,000 when the assumed $500 of work income ends. Keeping the lower withdrawal forever would describe a different budget.
