Boxing Day. The wrapping paper's been stuffed in bin bags, the Quality Street tin is already half empty, and somewhere between the turkey sandwiches and the sofa, reality starts creeping back in.

How much did Christmas actually cost you?

The Average UK Christmas Spend

According to recent surveys, the average UK household spends between £1,000 and £1,500 on Christmas. But that headline figure hides a lot:

CategoryAverage Spend
Gifts£400-600
Food & drink£200-300
Decorations£50-100
Travel£100-200
Going out (December)£150-250
Christmas outfit£50-100

The hidden costs: Delivery charges, gift wrap, batteries, emergency top-up shops, the round you bought at the work do.

Time to Face the Numbers

Grab your phone and check:

  1. Bank statements - December 1st to today
  2. Credit card balance - Compare to November
  3. Buy Now Pay Later - Klarna, Clearpay, PayPal Pay in 3
  4. Cash withdrawals - The untraceable spending

Add it all up. Don't flinch.

If You're Carrying Christmas Debt

You're not alone. Around 30% of Brits put Christmas on credit. The question is: what's your payoff plan?

The January trap: Minimum payments on a £1,000 credit card balance at 22% APR:

  • Minimum payment: ~£25/month
  • Time to clear: 5+ years
  • Total interest: £500+

The better approach: Fix your monthly payment at what you can afford and don't reduce it as the balance drops.

The Boxing Day Sales Trap

The irony of Boxing Day: trying to fix overspending with more spending.

Before you hit the sales, ask:

  • Did I actually want this before I saw the discount?
  • Would I buy it at full price?
  • Am I buying it because it's "70% off" or because I need it?

A £100 jacket marked down to £30 isn't a £70 saving. It's a £30 spend.

Your Post-Christmas Financial Reset

This Week

  1. Total up the damage - You can't fix what you can't measure
  2. Set a debt payoff date - Not "eventually"
  3. Return what you don't need - Most stores extend returns until mid-January
  4. Sell unwanted gifts - eBay, Vinted, Facebook Marketplace

January

  1. No-spend first week - Use what you've got
  2. Cancel free trials - The ones you signed up for to get Christmas discounts
  3. Review subscriptions - How many streaming services do you actually watch?

Ongoing

  1. Start a Christmas fund - £100/month from January = £1,200 by December
  2. Set spending limits - Agree with family for next year
  3. Consider a Secret Santa - One gift instead of twelve

The Christmas Sinking Fund

The best time to prepare for Christmas 2026 is now, while the financial pain is fresh.

The maths:

Monthly SavingBy December 2026
£50£600
£100£1,200
£150£1,800

Put it in a separate account. Make it automatic. Forget about it until next November.

Run Your Numbers

The Bottom Line

Christmas is over. The memories are made. Now it's time to deal with the aftermath honestly.

The goal isn't to feel guilty about what you spent. It's to face the numbers, make a plan, and set yourself up so next December doesn't feel like this.

Boxing Day isn't just about sales. It's the perfect day to start taking control.
