Asha, one salary, a rented flat in Bristol
Asha works for the NHS on a predictable rota. Take-home pay is steady. The flat is a one-bed in BS7, close enough to Henleaze that we pass the same terraces. Her essential month comes to £1,540: rent, a single-person council tax bill, energy, a modest food shop, a bus pass, contents insurance and her phone.
She has no children and a permanent contract, but only one income. Three months, £4,620, is the figure she writes on the jar in the banking app. She also keeps £250 in the current account so a weekend fuel top-up does not touch the fund. Her standing order is £180 on payday. At that pace the empty fund fills in about twenty-six months, which felt slow until she noticed she had previously saved nothing. A tax-free bonus of £600 was split £300 to the fund and £300 to a trip she had already priced. The trip was not an emergency. Labelling it stopped it becoming one.
Tom and Priya, a mortgage and a nursery invoice
Their essential month is £2,880, and childcare is the line that shocked them. Without the nursery the household still functions, but Priya cannot work the hours her contract expects. They counted childcare as essential. Six months is £17,280. They will not raise that in a year, and pretending otherwise made them abandon a £100 standing order.
They reset. First target: one essential month, £2,880, in an easy-access account named for the mortgage date. Second target: three months. Six months is written down as the place they are going, not the place they must reach before they are “allowed” to feel finished. Each of them has a £40 personal pot so birthday presents do not come out of the joint fund. When the car needed tyres they had seen coming, they used a separate car line they had been funding at £30 a month. The emergency account did not move. That was the whole point of the second pot.
Lewis, invoices, and a tax pot that is not the fund
Lewis is a freelance designer. Some months pay £4,000. Some pay £600. He used to keep one savings account called “safety” and then send a large slice of it to HMRC in January. After the payment he had £400 left and called it an emergency fund. It was a tax bill that had been early.
He now runs three names. Tax reserve: a percentage of every paid invoice, moved the day the client pays, at a rate he checks against his accountant’s figure each April. Emergency fund: aimed at nine essential months because a quiet quarter is ordinary in his trade, not a surprise. Spending: what remains. The emergency account is easy access. The tax reserve is also easy access, because HMRC does not wait for a 90-day notice, but it is not available for a new laptop. When a client paid late and the boiler failed in the same fortnight, the boiler came from the emergency fund and the late invoice rebuilt it. The tax pot was not “borrowed”. That single refusal is the practice.
Hannah, the year her salary paused
Hannah and her partner planned maternity leave a year ahead. Statutory pay is not a full salary, and they did not want the emergency fund to become the maternity plan. They opened a named pot, “Leave”, and filled it with the gap between essential costs and the income they expected during leave. The emergency fund stayed at four months of essentials, untouched, for the things a birth year actually throws up: a washing machine, a train to a grandparent who fell, a week of extra heating.
The lesson we kept was the split. A planned drop in income is a sinking fund. An unplanned bill during that drop is the emergency fund. Mixing them means the planned drop consumes the unplanned protection by November.
What the four notes share
- The target is a multiple of essentials, rewritten when life changes.
- The first milestone is allowed to be smaller than the final one.
- Money with a date on it — tax, Christmas, a known income gap — does not live in the emergency account.
- The account name is part of the control. So is the standing order.
- Nobody in these notes beat a market. They stopped using tomorrow’s rent as today’s flexibility.
