A family holiday is one of those things that feels impossible right up until the moment you book it. Then it feels obvious. The difference is usually not income — it is having a plan, a separate pot of money and a date in the diary. Here is how to get there without a last-minute scramble onto a credit card.

Start With the Real Cost, Not the Headline Price

The price on the holiday website is rarely the price you pay. Before you set a target, sit down and add up everything the trip will genuinely cost. It is better to discover a £400 gap now than in the departure lounge.

• The holiday itself — flights, accommodation, transfers or car hire, and any baggage fees.
• Travel insurance — buy it when you book, not the week before you go.
• Passports and visas — a UK adult passport renewal is not cheap, and children's passports expire faster than you expect.
• Spending money — a realistic daily figure, plus a buffer. Work out what a meal out and a few ice creams actually cost where you are going.
• The boring extras — airport parking or train fares, pet boarding, a new suitcase, currency exchange fees.

Add it all up and you have your number. For a family of four spending a week abroad in the school summer holidays, somewhere between £2,500 and £4,000 all-in is a common range. Your figure will be your own, and that is fine — the point is that it is real.

Open a Separate Savings Pot

Money that sits in your current account gets spent. It is not a character flaw; it is just how current accounts work. Open a separate savings account and give it a name — "Holiday 2026" works well — so you can see at a glance whether you are on track.

Look for an account you can access without penalty, because you will be withdrawing from it on a set date, but one that is not instantly linked to your debit card. A little friction is useful. If you already have an easy-access savings account, a second one for the holiday keeps things clean and stops you raiding the emergency fund for a sun lounger.

If you are saving over a year or more, a regular saver or a fixed-term account might pay more interest, but check the rules on withdrawals first. Earning 4% and then losing access when you need to pay a deposit is no good to anyone.

Set a Monthly Target You Can Actually Hit

Divide your total by the number of months until you need to pay. If the holiday costs £2,400 and you have twelve months, that is £200 a month. Set up a standing order for the day after payday, so the money leaves before you have a chance to notice it.

If £200 a month is not realistic, you have three honest options: save for longer, aim for a cheaper trip, or find the difference elsewhere in the budget. Reviewing a few subscriptions and a couple of takeaway habits often frees up £50 to £80 a month without much pain. That is £600 to £960 a year — a meaningful chunk of most family holidays.

Track it monthly. A quick note on the fridge or a spreadsheet both work. Seeing the balance climb is genuinely motivating, and it tells you early if you are falling behind while there is still time to adjust.

Book Early and Lock In the Price

For UK families, the single biggest saving is booking early. School holiday dates are fixed and everyone is chasing the same weeks, so prices climb steadily from January onwards. Booking six to nine months ahead typically costs noticeably less than booking in May for August.

Booking early also gives you something more valuable than a discount: certainty. You know the total, so your monthly target is accurate rather than a guess. Pay a deposit if it helps, but make sure you know the date the balance is due and diarise it. Set a reminder two weeks before so a missed payment never catches you out.

If the balance falls due before you have finished saving, that is a signal to start your pot earlier next time — not to reach for credit.

Involve the Children

Children are far more invested in a holiday they helped pay for, and far less likely to nag for extras when they understand the budget. You do not need to share your salary, just the goal.

• Make a chart. Colour in a section for every £100 saved. It turns an abstract number into something they can see.
• Give them a job. Older children can compare prices, research free days out or keep an eye on currency rates.
• Let them contribute. Birthday money, pocket money or a small earnings target for teenagers. Even £20 makes a difference to how they behave abroad.
• Agree a daily spend in advance. "£15 each per day" is much easier to stick to than an open-ended yes.

Protect the Pot and Keep Going

Two last things. First, keep a small buffer inside the holiday fund — £150 or so — for the unexpected: a taxi you did not plan for, a bag that goes missing, a rainy day that needs a cinema. Second, if you have to dip into the pot for a genuine emergency, do not abandon the plan. Reduce the target, extend the timeline, or trim the trip. Just keep the standing order running.

Saving for a holiday is not about being brilliant with money. It is about deciding early, separating the cash, and letting a boring monthly transfer do the hard work while you get on with looking forward to it.
