01What are bank pots?
Most UK digital banks let you split your money into labelled pots inside your account. Monzo calls them Pots. Starling calls them Spaces. Chase has roundup pots. The idea is the same: separate your money by purpose so it doesn't all sit in one pile waiting to be spent.
For debt payoff, that matters. If your snowball payment sits in your main balance alongside your grocery money and your direct debits, it gets spent. Not deliberately. It just blends in, and by the end of the month it's gone.
A pot fixes this. On payday, you move your extra debt payment into a pot. It's still your money, still in your account, but it's not in the balance you see when you tap your card at Tesco. Out of sight, harder to spend.
Every UK digital bank handles pots slightly differently. Here's what you actually get with each one.
02Monzo Pots and Monzo Perks
Monzo gives every account holder pots for free. You can create as many as you like, name them whatever you want, and schedule automatic transfers into them. That's the bit that matters for debt payoff: set a scheduled transfer on payday, and the money moves before you can spend it.
If you're on a paid Monzo plan (Monzo Plus at £5/month or Monzo Premium at £17.50/month), you also get Open Banking account linking. You connect your credit cards and other bank accounts, and all transactions show up in one place. No need for a separate spending tracker app.
That means you can see your Barclaycard transactions, your Amex balance, your HSBC current account, and your Monzo spending all in one feed. If you're snowballing three or four credit cards, that saves you logging into four different apps to check whether minimums have cleared.
The free version doesn't include Open Banking linking, but pots and scheduled transfers work on every Monzo account. If you're only paying off one or two debts, free Monzo with a pot called "TrySnowball" does the job.
One practical note: Monzo pots can earn interest if you choose a savings pot (rates vary, currently around 3.5-4% AER on some options). For a debt payment pot you'll empty each month, a regular pot is fine. Don't overthink it.
03Starling Spaces
Starling Spaces work much like Monzo Pots. You create named spaces, set spending targets, and schedule regular transfers in. Setup is straightforward and the scheduled transfers fire on time.
Starling also offers Open Banking aggregation on its paid plans, so you can see external accounts alongside your Starling balance. Same benefit as Monzo Perks for tracking multiple debts in one place.
One thing Starling does differently: you can set a goal amount for each Space. So you could create a "Snowball Payment" space with a £150 target, and the app shows your progress towards filling it each month. Small thing, but it makes the pot feel purposeful rather than just a holding pen.
Starling's free account includes Spaces and scheduled transfers. You don't need the paid plan unless you want the account aggregation.
04Chase roundups
Chase UK takes a different approach. Instead of manual pots, they offer automatic roundups: every time you spend on your Chase debit card, the transaction gets rounded up to the nearest pound and the difference goes into a savings pot.
Spend £3.40 on a coffee, 60p goes into the pot. Over a month of normal spending, roundups typically collect £20-40 without you noticing.
That's not going to clear a £5,000 credit card on its own. But it's money you wouldn't have saved otherwise. At the end of each month, move the roundup balance to your focus debt as an extra payment.
Chase doesn't have the same manual pot system as Monzo or Starling, so it's less useful for ring-fencing a specific monthly debt payment. Think of it as a supplement: roundups collect the loose change, while a standing order handles the main snowball payment.
05Setting up a debt payment pot
Here's the actual setup. Takes five minutes on payday.
1. Create a pot called "TrySnowball." Open your banking app, create a new pot, and name it. The name reminds you what the money is for, and honestly, we like seeing it in screenshots. You could call it "Debt Payment" or "Extra Payment" if you prefer, but "TrySnowball" has a ring to it.
2. Work out your snowball amount. Open the free calculator, enter your debts, and check the extra payment figure. That's the amount beyond your minimums that goes towards your focus debt. Even £30 matters.
3. Schedule a transfer on payday. In Monzo: go to the pot, tap "Add money", then "Scheduled payment." Set it for your payday date, monthly repeat. The money moves automatically before you can spend it. Starling and other banks have similar options in their Space or pot settings.
4. Set up standing orders for minimums. If you haven't already, set a standing order to each lender for their minimum payment, timed for a day or two after payday. Minimums are non-negotiable. Miss one and you get hit with a late fee plus a mark on your credit file.
5. Pay your focus debt from the pot. Once the pot fills on payday, transfer the money to your focus debt. In TrySnowball, that's the debt at the top of your snowball list. One debt gets all the extra. Don't spread it across everything.
06Making it fully automatic
The five-minute payday routine above works. But you can also automate the whole thing so you never have to think about it.
Standing orders handle minimums. A scheduled pot transfer handles the snowball payment. The only manual step left is moving money from the pot to your focus debt, and some people automate that too with a second standing order directly to the lender.
You're taking yourself out of the loop. Not because you can't be trusted with money, but because remembering to manually transfer £50 to a credit card on the 27th of every month is the kind of thing that stops happening by month four.
If you're using Monzo Perks or Starling with Open Banking, you can check all your balances without opening multiple apps. One glance tells you: minimums cleared, pot is funded, focus debt is going down. Done.
Boring paydays are good paydays. The less you have to think about your debt payments, the more likely they actually happen. Set it up once, check it works for a month, then forget about it.
07Which bank is best for debt payoff?
Short answer: whichever one you already use. The best pot system is the one you'll actually set up.
Monzo is strongest if you have debts across multiple lenders and want to see everything in one app. The paid plans with Open Banking linking save you from needing a separate tracker like Snoop or Emma. The free plan is solid for pots and automation.
Starling is similar in features. The goal-based Spaces add a nice visual element if seeing progress towards a monthly target motivates you. Same Open Banking aggregation on paid plans.
Chase is best as a supplement. Roundups collect spare change passively, but you'll want a separate standing order for your actual snowball payment. Chase doesn't replace the main debt payment setup.
None of these banks plan your debt payoff for you. They move money where you tell them to, and they show you your balances. TrySnowball handles the strategy: which debt to pay first, how much time you're saving, and when you'll be done. The bank handles the plumbing.
