Emergency fund calculator

An emergency fund covers your essential costs if your income stops or a big bill arrives. Add up what you must pay each month, choose how many months to cover, and see your target and how long it will take to save it.

Your numbers

How many months should you cover?

Three to six months of essential costs is the range most often suggested. Lean towards the upper end, or beyond, if:

What counts as "essential"?

Only what you would still have to pay in a lean month: housing, groceries, utilities, insurance, transport to work, and minimum debt payments. Leave out subscriptions, eating out and extra debt payments, which you could pause.

How this calculator works

Target = essential monthly costs × months to cover. The time to reach it is the amount still to save divided by what you can save each month, rounded up to whole months. It does not add interest, so if you keep the fund in a high-yield savings account you may get there a little sooner.
