Let’s be honest — most of us use our debit cards every single day. Groceries, subscriptions, transport, coffee, bills. But what if that everyday spending could quietly work in your favour?
In 2026, thousands of UK customers are learning how to make money with Monzo or Starling cards without changing their lifestyle. No complicated investments. No risky schemes. Just smarter use of features already built into leading digital banking apps.
If you’ve ever wondered whether you’re leaving money on the table, this guide will show you exactly how to turn routine transactions into small but consistent gains.
The UK fintech landscape has matured significantly. Thanks to open banking, advanced budgeting analytics, and competitive digital banking apps, customers now benefit from:
Unlike traditional high-street institutions, digital banks focus heavily on financial wellbeing and customer engagement — which often means tangible perks.
But how exactly can you turn these into income?
One of the simplest ways to make money with Monzo or Starling cards is through cashback rewards.
Cashback is typically offered via:
Instead of collecting points, you receive actual pounds back into your account.
“Cashback on essential spending can effectively reduce your annual household costs without increasing risk.” — Martin Lewis
| Spending Category | Avg Monthly Spend | 3% Cashback Example | Annual Return |
|---|---|---|---|
| Groceries | £300 | £9 | £108 |
| Transport | £120 | £3.60 | £43.20 |
| Dining | £150 | £4.50 | £54 |
| Subscriptions | £80 | £2.40 | £28.80 |
Even modest percentages can generate over £200 per year.
Would you ignore £200 lying on the pavement?
Referral bonuses remain one of the fastest ways to earn money with UK digital banking apps.
Most authorised institutions run periodic referral campaigns where both parties receive a fixed bonus once eligibility criteria are met.
| Referral Activity | Bonus per Person | 5 Referrals | 10 Referrals |
|---|---|---|---|
| Standard Campaign | £10 | £50 | £100 |
| Limited Promo | £15 | £75 | £150 |
Used ethically, referral bonuses can add a meaningful side income stream.
Round-up features automatically round transactions to the nearest pound and transfer the spare change into savings pots.
At first glance, this feels small. But let’s look closer.
If you average 40 transactions per month with an average 45p round-up:
Now add interest (if available through savings interest rates or savings accounts).
This strategy supports financial wellbeing while quietly building capital.
Some digital banks allow you to allocate funds into separate pots for goals.
If linked to interest-bearing savings or external integrations, you can:
Reducing overdraft fees is itself a form of making money — by preventing losses.
Card-linked offers connect your debit card to retailer promotions.
You activate the offer inside your banking app, shop normally, and receive cashback automatically.
This strategy requires almost zero effort.
Ask yourself: if you’re already spending, why not activate the offer first?
Transaction insights and automated budgeting allow users to track:
Many users discover £50–£100 monthly waste.
That’s £600–£1,200 per year recovered — without earning extra income.
“Financial awareness is often more profitable than high-risk investing for average households.” — Martin Lewis
