How Does Cashback Work on a Current Account?
A cashback account rewards you for payments you make every month. The amount you earn, the purchases that qualify, and when you get the money varies between banks. Some accounts – like Biscuit by Zopa – offer cashback with no monthly fee, so the extra money you earn costs you nothing. Nice, right?

What to look for in a cashback current account
What is cashback on a current account?
Think of cashback as a little thank you from your bank every time you spend. Instead of loyalty points or air miles that can take months to add up to anything useful, cashback comes back to you as actual money.
Here’s how it works. When you pay for something, your bank calculates a percentage of what you spent and rewards you. No vouchers, no claiming required – just a straightforward way of getting a little extra.
It's worth understanding how cashback bank accounts work before you pick one, because the terms can vary from bank to bank. Once you know what to look for, it's all pretty straightforward.
How is cashback calculated?
The way your cashback is worked out depends on the approach your bank uses. The two main ways are:
Percentage-based cashback
With percentage-based cashback, your bank applies a fixed percentage to every eligible payment. This is the most common approach. It’s also how our Biscuit bank account works.
With Biscuit, you earn 2% cashback on up to £125 of Direct Debits each month. That includes things like some bills, subscriptions and broadband. The more eligible Direct Debits you have, the more you earn. Simple.
Fixed monthly cashback
Some accounts offer a fixed cashback reward for specific actions.
For example, you might get £5 back if you spend a certain amount in a month, or £7 for paying your utility bills through the account.
This model can feel more predictable, but it can also be more limiting if you don’t hit the spending target.
Which purchases qualify for cashback?
This is where it pays to read the small print. Not all spending counts, and the rules can vary quite a bit.
Some accounts reward you for spending on supermarket and grocery shopping, petrol stations and fuel, utility bills, online retail purchases and subscription services.
Payments that don't usually qualify for cashback include cash withdrawals from ATMs, gambling transactions, credit card balance transfers or refunds, and purchases made abroad.
Remember, with Biscuit it’s your Direct Debits that earn cashback – not debit card purchases. So regular payments like your energy bill, broadband and subscriptions all count, and every month they go out, you earn.
To see exactly which purchases earn you cashback , it's always best to check directly with your bank.
When is cashback paid into your account?
Most cashback accounts – yep, including Biscuit – pay out once a month. The exact date varies – some providers pay on a fixed calendar date, others pay on your account anniversary.
There's often a short delay between buying something and seeing the cashback appear. This is because banks typically wait for the payment to fully go through before calculating and awarding cashback. In practice, this means cashback earned one month might show up a few days into the next.
Is there a cap on how much cashback you can earn?
There usually is a cap on the payments that qualify for cashback each month, which in turn limits how much you can earn. This is usually tied to the account's fees – free accounts are more likely to have caps, while paid accounts sometimes offer no limit on what you can earn.
For example, an account might offer 2% cashback on all debit card spending, but cap your monthly earnings at £15. If you spend £1,000 in a month, you'd earn £15 rather than the £20 the percentage would suggest.
We've kept it nice and simple with Biscuit: 2% cashback on up to £125 of Direct Debits each month. Together with interest, you could earn up to £192 a year (read about how we calculated that). We reckon it’s an easy, consistent reward on bills you were always going to pay, with no monthly fee eating into it.
Do you need to pay a monthly fee to get cashback?
Not necessarily – and this is an important point. People assume that cashback accounts always come with a monthly charge, but it’s getting more common for free accounts to offer cashback. There’s absolutely no monthly charge with Biscuit, for example.
When an account does charge a monthly fee, you need to factor that cost into your calculations. If you're paying £5 a month but only earning £3 in cashback, you're losing money. The fee needs to be lower than your regular cashback earnings before the account makes financial sense.
A fee-free account like Biscuit removes that maths entirely. Everything you earn goes straight back to you.
That said, paid accounts aren't always bad value. Some offer higher cashback rates, cashback on more of what you buy, or high interest on the money sitting in your account – that can justify the cost if you use the account heavily enough.
What to look for in a cashback current account
With a growing number of cashback accounts on the market, here's what to focus on when comparing your options:
Cashback rate
What percentage are you actually earning on your everyday spending? A high headline rate that only applies to a narrow category of purchases is less useful than a slightly lower rate that applies more broadly.
Qualifying purchases
Does the cashback cover the things you actually buy? If you mostly spend on groceries and fuel, make sure those categories qualify. If you have regular Direct Debits going out each month – rent, bills, subscriptions – an account like Biscuit earns you cashback on spending you were always going to make.
Monthly caps
Check whether there's a limit on how much you can earn. For big spenders, a cap can make a lot of difference to what you actually earn from cashback.
Fees
Weigh any monthly fee against your expected cashback earnings. A fee-free account that offers solid cashback is often the most straightforward option.
Additional perks
Some accounts combine cashback with other benefits, like interest on the money sitting in your account. Earning in two ways at once means your money is working harder in more ways than one.
We’re proud to say that Biscuit ticks all these boxes – 2% cashback on up to £125 of Direct Debits each month, interest on your balance, and no monthly fee. It's well worth a look: find out more about Biscuit by Zopa.

Your questions answered
Is cashback on a current account taxable?
In most cases, no. HMRC generally treats bank account cashback as a discount on your spending rather than income, so it isn't subject to income tax. That said, tax rules can change, and individual circumstances vary – if you're in any doubt, it's worth checking with a tax adviser.
What is the best cashback bank account in the UK?
The best account depends on your spending habits. Compare cashback rates, qualifying payments, and any caps or fees before you decide. Biscuit by Zopa offers 2% cashback on up to £125 of Direct Debits each month, plus interest on your balance – all with no monthly fee.
Do you get cashback on Direct Debits?
It depends on the account. Most cashback accounts reward debit card purchases rather than Direct Debits. Biscuit is a notable exception, so it’s a great fit if you have regular bills going out.
How long does cashback take to appear in your account?
Most cashback is paid within one to two months of an eligible purchase, once the payment has fully cleared. Many accounts pay out on a monthly cycle, so cashback earned throughout the month typically appears as a lump sum shortly after the month ends.
Do you need to switch banks to get cashback?
Not always – and with Biscuit by Zopa, you definitely don't. You can open a Biscuit account alongside your existing bank and set up your Direct Debits to pay out from it, without any disruption to your regular banking setup.
