A note on a considered transition
Career-switch cash runway
Estimate how long available cash covers a monthly shortfall. Separate protected savings from money you can genuinely use for the switch.
Scenario notes
Model boundary
Usable cash = max(0, savings โ protected cash โ upfront costs). Monthly shortfall = max(0, expenses โ retained income). Runway = usable cash รท shortfall. With no shortfall, no drawdown is modeled; this is not unlimited financial security. Excludes uncertain job offers, interest, investment changes and unentered expenses.
