Building an emergency fund on an irregular income

Fixed targets fail on variable income

Advice to save a set amount every month assumes a set income every month. If yours moves, that target is unreachable in lean months and too easy in good ones.

Save a percentage instead

Commit to a share of whatever arrives, for example ten or fifteen percent. It scales automatically, and it removes the monthly decision about whether you can afford to save.

Size the target to your fixed costs

Three months of essential spending is a sensible first goal: rent or mortgage, utilities, food, transport, minimum debt payments. Not three months of total spending, which is a much larger and more discouraging number.

Keep it separate and slightly inconvenient

A different account, without a card attached, is enough friction to stop casual spending while keeping the money genuinely accessible in a real emergency.
