Why emergency funds and deductibles belong together
A normal emergency fund calculation often ignores the cash you need before insurance pays. Deductibles, excesses, temporary repairs, replacement transport, medical out-of-pocket costs, and income gaps can all arrive before reimbursement or claim settlement.
How to interpret the target
This is a planning estimate, not financial advice. A household with unstable income, dependents, high deductibles, or limited family support may need a larger buffer than someone with stable income and low insurance excesses.
