Most of us could tell you roughly what the rent, phone contract and food shop cost each month. The bills that cause trouble are the ones that turn up once or twice a year: the MOT, the car insurance renewal, a run of family birthdays, the build-up to Christmas. They are not really surprises, because they arrive around the same date every year, but they often feel like it.
When one of those costs lands in a month that is already tight, it is tempting to reach for a credit card or an overdraft. A bit of planning now means the money is sitting there ready when the bill arrives. Here is how to set that up in an afternoon.
Step 1: List every cost that is not monthly
Grab a notebook or open a spreadsheet, then scroll back through twelve months of bank statements. Write down anything that was not a regular monthly payment. Common ones include:
- Car costs: MOT, servicing, insurance if you pay it yearly, vehicle tax, breakdown cover and tyres.
- Home costs: a boiler service, home insurance, the TV licence and any one-off repairs.
- Family costs: school uniform, trips, birthdays, clubs and holiday childcare.
- Seasonal costs: Christmas, summer holidays and the back-to-school rush.
- Yearly renewals: memberships, software, a delivery pass or a magazine subscription.
Put the amount you paid last time next to each one. If you are not sure, guess on the high side.
Step 2: Turn your list into an annual costs calendar
Now slot each cost into the month it falls due. A simple twelve-row table is fine, or you can set phone reminders a few weeks before each date. The aim is to see the whole year at a glance, so the expensive months stop creeping up on you.
You will probably spot a few crowded months. For lots of households, autumn and winter are the toughest stretch, with heating, school costs and Christmas all landing together. Knowing that early gives you time to move what you can. Some insurers let you pick your start date when you switch, and many councils will spread council tax over twelve monthly payments instead of ten if you ask.
In England, Scotland and Wales you can have your MOT done up to a month (minus a day) before it runs out and keep the same renewal date. That gives you a little wiggle room to book it just after payday.
Step 3: Set up sinking funds for the big bills
A sinking fund is a pot you fill gradually for one known expense. Take the yearly cost, divide it by the months left until it is due, and put that amount aside each month. If your car insurance renews in ten months and cost £600 last time, saving £60 a month covers it.
If your bank app lets you create separate savings pots, this is easy, because you can name each one and watch it grow. If not, a separate easy access savings account works just as well. The important thing is keeping this money away from your everyday spending so it does not quietly vanish.
You do not need a pot for every small item. Lump the little ones together into a single "annual extras" pot and give the larger bills their own.
Step 4: Decide whether to pay monthly or yearly
Plenty of annual bills can be paid in monthly chunks, which feels easier. Before you choose, check the total each way. Paying car insurance monthly often costs more over the year, because the insurer may be lending you the premium and charging interest for it. Vehicle tax spread across monthly or six-monthly payments also works out slightly dearer than paying for twelve months upfront.
Once your sinking fund has built up, paying yearly can work out cheaper. Until then, some people prefer monthly payments to avoid a large one-off cost. Either way, it helps to make the choice on purpose rather than by default.
Step 5: Keep a buffer for the costs nobody can predict
Even the best calendar will not tell you when the washing machine is going to give up. Alongside your sinking funds, try to build a general emergency buffer, even if it starts with a few pounds a week. Our guide to the key numbers in your budget explains how to set a sensible target. And if something does go wrong, read using savings or borrowing before you decide how to pay for it.
Check in on your plan every few months
Prices change, policies renew at different amounts and family life moves on. Every three or four months, take ten minutes to update your calendar, check your pots are on track and add anything new. It is far easier than catching up after a bill has already gone out.
