What this calculator actually models
Withdrawal planning is the reverse of accumulation: a starting balance can keep earning while money is removed. This calculator solves a level monthly withdrawal that mathematically depletes the balance at the end of a target period, or tests your own withdrawal against the same constant-return model.
How to use this calculator
Enter starting savings, annual return assumption and withdrawal period.
Leave monthly withdrawal blank to solve the level drawdown, or enter a withdrawal to stress-test it.
Review modeled monthly draw, months funded and ending balance, then read the limitations before using the result for planning.
Where people use it
- •Simple retirement drawdown illustrations
- •Testing whether a fixed monthly withdrawal depletes savings early
- •Comparing withdrawal periods under the same return assumption
Example: zero-return drawdown
With no investment return, 120,000 spread evenly over 10 years equals 1,000 per month for 120 months.
Assumptions and limits
- •A constant return is not how real markets behave; sequence-of-returns risk can materially change outcomes.
- •This model does not increase withdrawals for inflation.
- •Taxes, fees, pensions and guaranteed-income products are excluded. This is not a safe-withdrawal-rate recommendation.
Frequently asked questions
Is this a retirement safe withdrawal calculator?+
It is a deterministic drawdown calculator, not a claim that any withdrawal rate is safe.
What happens if I leave monthly withdrawal blank?+
The calculator solves the level monthly amount that reaches approximately zero at the end of the selected period under the constant-return assumption.
Does it account for inflation?+
No. Withdrawals remain level in nominal terms.

Keep the result connected to the real job
MAXScanner keeps the formula and assumptions beside the result so you can verify the number before using it in a drawing, estimate, specification, worksheet or document. Where a supplier, manufacturer, drawing or applicable standard owns a requirement, that source remains authoritative.
