Simple payment hack could see Britons get a £41 boost on their Christmas shopping

British households could earn more than £41 in cashback from festive spending alone, according to new analysis from cashback and investment app Kaldi.

The research suggests that with typical Christmas outgoings of around £853 on food, gifts and seasonal essentials, shoppers using cashback-linked platforms could receive £41.24 back through a combination of standard and boosted rates.

Kaldi tracks purchases made through its app and pays cashback from more than 130 UK retailers, with the option for users to place those rewards into investment accounts such as ISAs, JISAs or GIAs.

The firm says this does not require shoppers to change where or how they spend, but simply alters how payments are routed.

The research shows an average £350 festive food shop could generate around £14 in cashback at a four per cent rate, while spending of roughly £147 on Christmas supplies such as decorations and batteries could return £5.88.

Gift buying accounts for the largest share, with nearly £356 spent on presents producing £21.36 back at an average cashback rate of six per cent.

While the sums involved may appear modest, the analysis suggests that small percentages on routine spending can add up over time, particularly for households already facing higher seasonal costs.

For many families, this represents money they would otherwise fail to capture, earned automatically from expenditure already planned.

The enhanced rates during the festive period make Christmas one of the simplest opportunities to begin building cashback rewards.

Rather than allowing these returns to remain unclaimed, users can direct them straight into investment vehicles through the platform.

Households maintaining this cashback habit throughout the year could accumulate roughly £196 annually, equivalent to £16.34 monthly from regular spending patterns.

This yearly total breaks down to approximately £116.76 from grocery shopping, £54.30 from clothing purchases, and £24.93 from personal items such as toiletries and cosmetics.

The real power emerges when these modest sums are invested rather than left dormant. Based on projected returns between 7.57 per cent and 11.49 per cent annually, the figures demonstrate remarkable growth potential.

After a decade, £1,960 in accumulated cashback contributions could swell to between £2,879 and £3,530. Extending the timeframe to twenty years, £3,921 invested might reach anywhere from £8,854 to £13,999.

Over three decades, total cashback of £5,882 could potentially compound into a sum ranging from £21,255 to £45,054, transforming otherwise overlooked pennies into substantial savings without any additional household expenditure.

Justin White, Chief Operating Officer at Kaldi, said: “Christmas is one of the biggest spending moments of the year, but it’s also one of the easiest times to earn cashback.

“By starting with Christmas shopping, households can see immediate value and if they keep going throughout the year, those small amounts can turn into something meaningful over time.

“And, because we have cashback deals with so many different retailers, as well as restaurants, pubs, takeaways, and even hotels and leisure brands, users don’t even need to shop differently or spend more.

“This helps people build up investments without changing their lifestyle. With the cost of living still front of mind, Kaldi is designed to make everyday spending work harder quietly, automatically and without fuss.”
