How to Clear Christmas Debt: A New Year Payoff Plan

6 min read · UK focused · Updated 6 Aug 2026

To clear Christmas debt, list every festive balance, clear any buy-now-pay-later plans before their 0% deadlines to dodge backdated interest, then pay off the rest smallest-balance-first with a fixed monthly overpayment. Aim to be clear before the next festive season, and start a small monthly savings pot so next year is paid in cash.

Festive debt has a nasty habit of surviving until summer and then colliding with next December's spending. This four-step plan breaks that cycle: clear this year's balances quickly, then turn the same monthly amount into next year's savings.

Step 1: Add up everything the holidays cost

List every balance the festive season created — credit cards, store cards, overdraft use and buy-now-pay-later — with the amount owed, the interest rate, and any 0% deadline.

Festive borrowing is easy to underestimate because it lands across several accounts at once. UK adults who borrowed for Christmas owed several hundred pounds on average going into the new year, and buy-now-pay-later has become one of the fastest-growing forms of festive credit. Writing it all in one place turns a vague worry into a fixed, clearable number.

Step 2: Beat the buy-now-pay-later deadlines first

Clear buy-now-pay-later plans before their interest-free windows close. Many backdate large interest charges or add missed-payment fees the moment you pass the deadline, so these come before ordinary card debt.

This is the one sensible exception to paying smallest-first. A buy-now-pay-later plan looks free until the deadline, then can become one of your most expensive debts overnight. From 2026 the FCA is bringing buy-now-pay-later under formal regulation, but until protections fully land you should treat every deadline as hard. Map each deadline and make sure nothing slips past it.

Step 3: Snowball the rest, smallest balance first

Once the deadlines are safe, pay every minimum and throw a fixed overpayment at your smallest remaining balance until it clears — then roll that payment onto the next-smallest.

This is the standard debt snowball, and it suits post-Christmas debt perfectly because festive balances are often small and clear quickly, giving you fast wins in January when motivation is fragile. Find the overpayment with the budget planner — a leaner new-year budget usually frees up more than you expect — then map the payoff in the calculator.

If two or three cards carry high rates, ordering by interest instead can save a little more — compare the two approaches in snowball vs avalanche. Either way, the size of the overpayment matters more than the order.

Step 4: Make next Christmas a savings pot, not a debt

Once this year's debt is clearing, redirect the same monthly amount into a separate savings account. Divide your typical festive spend by 12 and save that each month so next December is paid in cash.

This is a "sinking fund", and it is the step that stops the cycle. Saving roughly a twelfth of your festive budget each month from January means the whole thing is funded before the shops start decorating. Keep it in a cash ISA or easy-access savings account so it is separate from everyday spending and, ideally, earning a little interest instead of costing it.

1. Total your realistic festive spend (gifts, food, travel, social).
2. Divide by 12 for a monthly figure.
3. Automate that transfer into a dedicated cash ISA or easy-access savings account for the day after payday.
4. Spend from the pot in December — no card, no buy-now-pay-later.
