How much emergency fund is actually enough

The standard suggestion — six months of expenses — is a reasonable starting point and a poor finishing point. The real question is how long it would take to replace your income if it stopped tomorrow.

A salaried professional in a deep job market with a working spouse may be well covered at four months. A business owner with lumpy receivables and three dependents may need eighteen. Income volatility, not age, is the driver.

Where you hold it matters as much as how much. Emergency capital should be liquid within 24 hours, stable in value, and boring. Liquid and overnight funds, plus a sweep-in deposit, cover most situations.

Finally, treat health and term cover as part of the same calculation. Adequate insurance shrinks the emergency fund you need to carry in cash.
