How to Use This Calculator
Enter the requested values using the units shown. Keep all values consistent and review every assumption before interpreting the result.
Formula & Methodology
The calculator applies the displayed formulas directly to the entered values. Supporting outputs expose intermediate calculations rather than hiding them.
Worked example
If annual spending is $50,000 and part-time work supplies $20,000, a 4% withdrawal assumption produces a $750,000 portfolio target.
Returns, inflation, taxes, healthcare costs and part-time income are uncertain. A fixed withdrawal rate is a planning assumption, not a promise.
