The formula

How this number is built

target = essential monthly expenses × months of cover
Step by step

Calculating it yourself

Step 1

Count essentials only: housing, utilities, food, transport, insurance, minimum debt payments.

Step 2

Exclude discretionary spending — in a real emergency those stop.

Step 3

Choose the months of cover based on how quickly you could replace your income.

Step 4

Hold the money in an instantly accessible account, not in investments.

Step 5

Rebuild it as the first priority after any use, before resuming other goals.

Questions

What people ask next

Three months or six?

Three is a reasonable floor for stable dual-income households. Six or more suits single-income households, variable earnings or specialised roles that take longer to replace.

Should I pay off debt first?

A small starter fund of around one month usually comes first, then high-interest debt, then completing the fund. Otherwise every emergency goes back on the card.
