How to use this calculator
Adjust the inputs to your own scenario, then review the result alongside the assumptions below. The $ symbol is a currency label; the tool does not convert exchange rates.
Worked example
At 0% return and no withdrawal increase, $12,000 supports $1,000 monthly for exactly 12 months.
The formula
Each month grow the balance, then subtract the withdrawal; increase withdrawals at each year boundary and stop at depletion.
What the result means
Compare the output with the stated assumptions. Changing an input changes the arithmetic; it does not establish how a real trade or investment will perform.
Assumptions and limitations
Deterministic investment scenario, not retirement-account or eligibility advice. No tax, fees, variable returns, or guaranteed longevity. Final withdrawal may be partial.
