The 3–6 month rule is wrong for most people

It ignores your notice period, your sector, and whether anyone else in your house is earning. Nine questions, most of them one tap.

What does one month of essentials cost you?

The things you couldn't stop paying for if your income stopped tomorrow. Not your normal spending. Tap the i if you're not sure what counts.

Put in: rent or mortgage, council tax, gas, electricity, water, your food shop, getting to work, insurance, childcare, minimum debt payments, broadband and a phone.

Leave out: eating out, subscriptions, the gym, holidays, hobbies, gifts, and anything you currently save or invest.

Three that catch people out. Broadband stays, because you can't job hunt without it. Your phone stays, but the contract becomes the cheapest SIM that does the job, so use that figure instead. Annual bills like car insurance and the MOT get divided by twelve and included.

Don't set haircuts and replacing worn-out basics to zero either. Around £40 a month is honest for one adult.

Base it on where you live now, not somewhere cheaper you could move to. Moving isn't something you can do inside six months. More in the emergency fund guide

Put in a rough figure to carry on. You can refine it later.

If your income stopped tomorrow, how long to replace it?

Be honest about your own role and sector, not the national average.

Does anyone depend on your income?

Children, a non-earning partner, family you support. It leaves you less room to take a stopgap job or move for work.

What notice period is in your contract?

Paid notice is runway you already have. This is where UK numbers part company with the American rules of thumb.

Would you get redundancy pay?

Roughly how many months of essentials would it cover? Statutory pay rises with length of service, so long-tenured staff often have more here than they expect.

If your income stopped, how much of the bills would someone else's cover?

A partner or second earner in your household. This shrinks the monthly bill your fund has to cover, so it lowers your target.

Do you have debt above about 20% APR?

Credit cards, overdrafts, payday loans, buy-now-pay-later arrears. It changes the order you should do things in.

How much have you set aside already?

Cash you could reach this week. Not your ISA, not your pension.
