Christmas is 10 weeks away. Here's how to pay for it before it arrives.

Most New Zealand households find Christmas a strain on their finances. Looking at last Christmas data, nearly two-thirds of Kiwis said they felt some level of financial stress about it, and a quarter planned to lean on credit or buy now, pay later more than the year before⁽¹⁾.

The good thing about Christmas is that it's the one big expense that arrives on the same date every year, so you can plan for it like any other bill. Christmas Day is a Friday this year, which leaves ten Fridays between 16 October and the day itself, and a $2,000 Christmas works out at $200 a week if you start this Friday.

The presents are rarely what does the damage. The most expensive day of a Kiwi Christmas is some time in January, when the December credit card bill falls due, and interest starts on anything that hasn't been paid off.

Work out what last Christmas cost

The quickest way to a real number is your bank and card statements from last November through to the end of January, across every account. Christmas spreads a lot further than the presents, and once the food, the travel and the summer are added in, the presents are often the smaller share.

Two lists do most of the work. The first is people: everyone you'll buy for, with a dollar figure next to each name, including the teacher gifts, the Secret Santa at work and the children's birthday parties that somehow always fall in December.

The second is everything else. That covers the food and drink (households in MYOB's survey budgeted about $415 for it last year, against $140 a head for presents⁽¹⁾), the petrol or flights to see family, the tree, hosting, the summer holiday, and the first few weeks of January, which the last section of this piece comes back to.

Add the two lists together and compare the total with what the statements show. If the two numbers disagree, go with the statements, because the lists will have missed things like the extra groceries and the last-minute presents.

If Christmas at your place is small enough to fit inside a normal month of spending money, you don't need any of this, and it can come out of the spending account as usual. The rest of this piece is for households where December is the most expensive month of the year.

Divide it by the Fridays you have left

From Friday 16 October there are ten weekly pays before Christmas, or five if you're paid fortnightly.

The money should be separated from your everyday account. In SortMe's four-account structure, Christmas belongs in short-term savings, next to the car excess and next winter's flights, because it's a known cost with a known date. Or, if you'd prefer, set up a second savings account called Christmas. This takes a couple of minutes to open in most banking apps, and the name makes the balance hard to mistake for anything else.

Then set an automatic payment for the day after payday, the same way we suggest running the rest of your accounts in the payday-to-payday piece. Don't rely on memory alone to move money around. You don't need more life admin tasks. Set up automatic payments to remove the cognitive load and automate the money movement.

If the Christmas forecast is too tight, October is the time to remove some of the expenses. A family conversation about a Secret Santa for the adults, a $50 limit on presents, goes a lot better on a Sunday afternoon in October than December. And if you're hosting family Christmas, have a conversation now with family members about who's bringing what. This will help ease the grocery bill burden.

Treat Black Friday as part of the plan

Black Friday is 27 November this year, seven Fridays into the ten. Create a list of what you're buying for who, and put a reminder in your calendar to purchase gifts on Black Friday and take full advantage of the discounts.

Last year Black Friday was the busiest shopping day of 2025 for non-food retailers on Worldline's payments network, with $55.6 million spent⁽²⁾.

Consumer NZ has tracked prices in the weeks before Black Friday for several years. In 2023 it found 77% of the products it tracked could have been bought for the same price or less in the weeks before the sale⁽³⁾. In 2025, half of the products it followed had the same or a bigger discount at some point in the previous three months⁽⁴⁾. Some Black Friday deals are the best price of the year, but plenty are prices you could have had in September, so the sale label alone doesn't tell you which is which.

The "now" price on a sale label is written by the people who would like you to pay it, so treat it as the retailer's opening offer and check it against the price you wrote down.

The way to know is to run your own price check. Next to each gift on your list, write down what it costs today and where. When Black Friday arrives, compare the sale price with the one you wrote down, and buy only when it's lower. If you missed noting a price, Consumer NZ suggests checking the item's price history on PriceSpy or PriceMe before you buy⁽³⁾.

If you'd rather not check prices by hand, put the list in a spreadsheet: who it's for, what you're buying, today's price, and a link to the product page. An AI assistant with web access can check those links each week and tell you when something drops below the price you noted, and PriceSpy will send you an alert for anything it tracks.

If the air fryer for your mum is on the list and cheaper than it's been in weeks, Black Friday has done you a favour, and you should take it, with money you've already set aside for Christmas.

Use the card for convenience, and only if you clear it

A credit card is fine for Christmas when the balance is paid in full by the due date, and the points or the purchase protection can be worth having. If that's how you pay, clear the card from the Christmas account as you go, so the statement in January holds nothing you haven't already covered.

The card becomes a problem when it's the plan. Research going back more than forty years finds that people spend more when they pay by card than when they pay with cash. A 2024 review of 71 papers confirmed the effect: it's modest on average and strongest on purchases other people see, like the dinner out or the new jacket⁽⁵⁾. Paying by card separates the purchase from the feeling of money leaving, which researchers call the pain of paying, and it's your spending handbrake.

Plenty of people who mean to clear the card each month don't. A large US study, covering a quarter of all credit card accounts in the country, found that 29% of accounts regularly paid only the minimum or close to it⁽⁶⁾. One reason is that the minimum printed on the statement looks like the amount you're expected to pay, so people pay that figure instead of the full balance.

Card interest is usually the most expensive borrowing a household has. As an illustration, at around 20%, a $2,000 Christmas left on the card for a year costs roughly $400 in interest, on top of the $2,000 you spent. The credit bureau Centrix has noted that consumer arrears tend to peak after Christmas⁽⁷⁾, and we've written about which debts to clear first if you're already carrying a balance into this one.

Leave buy now, pay later out of it

SortMe's view is that buy now, pay later isn't worth using, at Christmas or any other time. The amounts it covers are small enough to save for over a few weeks and buy outright, and if something can't wait that long, the four payments are covering a shortfall in the budget that's worth finding.

Christmas makes the timing worse. On the common plan of four fortnightly payments, a present bought in mid-December leaves half its payments due in January, alongside the card statement and the school stationery list.

These apps are built to keep you spending, and the research supports that. A Harvard Business School study of US bank and card data found that once people start using BNPL, their spending rises and stays higher⁽⁸⁾. A 2020 UK survey by Which? found nearly a quarter of BNPL users had spent more than they meant to, with BNPL set as the default at checkout and discounts for choosing it both pushing people towards it⁽⁹⁾.

If you can't afford a present without splitting it into four payments, that's a sign something else in your budget is already using up the money. Find out what it is now, while there are still ten weeks to adjust the plan, instead of in January when the payments are already coming out of your account.

Where SortMe comes in

Working out last Christmas means scrolling through three months of transactions across every bank you use, which is where most households give up. SortMe connects accounts across banks and categorises the spending, so last November to January shows up as a total you can work from, with the food, the travel and the presents already separated.

Using tags to track Christmas spending

This year you can track Christmas as it happens. Create a tag in SortMe called something like Xmas26 and add it to each Christmas purchase as it comes through, whichever account or card it's on: the presents, the Black Friday air fryer, the ham and the flights to see family. By the end of January you'll have one total for everything Christmas cost, which tells you how close you came to your number and gives you next year's figure without any digging through statements. A massive time saver.

You can also set up the four accounts and the automatic transfers between them, so the Christmas account fills on payday without anyone remembering to move the money. The cashflow forecast shows the bills due in January before January arrives, so the card bill and the back-to-school costs don't land on top of Christmas as a surprise.

You can try SortMe for $1 for 7 days at sortme.com (after that, the plan price applies unless you cancel).

What to do before Friday

The January due date on the December card bill is the day Christmas gets expensive, because anything still on the card after that day starts collecting interest. It also lands in the same few weeks as the back-to-school costs and, if your employer brought the pay forward before the Christmas break, the longest stretch between pays of the whole year.

So before you divide your number by ten, add a January line to the second list. It should cover anything on the card that the Christmas account hasn't already paid for, the school uniforms and stationery, and an extra week of groceries for the long wait to the first pay of the year.

Then, this week, pull last November to January from your statements, write the two lists, open or rename an account called Christmas, and set the automatic payment for the day after your next pay. If you use SortMe, create your Xmas26 tag at the same time, so the first Christmas purchase is tracked from the day you make it. If the first transfer goes in on Friday 16 October, you get all ten Fridays, and every week you wait takes one away and makes the other payments bigger.
