Most people open a Monzo account for the spending features and only discover the savings tools later, almost by accident. That's a shame, because the savings side of Monzo is genuinely well built, and a lot of the value comes from features that just run quietly in the background once you've set them up properly.
This isn't about chasing the highest possible interest rate. It's about using the structure Monzo gives you so that saving stops being a monthly decision and becomes something that happens automatically, whether you remember to think about it or not.
Pots: the foundation of saving in Monzo
Everything in Monzo's savings setup is built around pots — separate spaces within your account that hold money away from your main spending balance. You can create as many as you want for different goals: an emergency fund, a holiday, Christmas, a house deposit, whatever you're working towards.
The reason pots work well as a savings tool isn't complicated. Money in a pot is harder to spend by accident, because it's not sitting in the balance you see when you tap your card. That small bit of friction is often enough to stop casual dipping into savings, without locking your money away completely, since you can move it back out instantly whenever you genuinely need to.
Some pots also pay interest on the balance, which turns them from a passive holding space into an actual savings product. Rates move with the wider market, so I'd always check the current rate in the app rather than assume it matches whatever you last saw advertised.
Round-ups: saving without noticing
Round-ups are one of the simplest automatic savings features I've seen done well. Every time you spend, Monzo rounds the transaction up to the nearest pound and moves the spare change into a pot of your choosing. Buy a coffee for £2.80, and 20p goes straight into savings.
On its own, 20p here and there doesn't sound like much. But across a normal month of card spending, round-ups can add up to a meaningful amount without you ever consciously deciding to save it. It's the kind of feature that works precisely because it doesn't ask anything of you after the initial setup.
Automatic savings rules
Beyond round-ups, you can set up recurring transfers into a pot on whatever schedule suits you, commonly tied to payday. This is the "pay yourself first" principle implemented directly in the app: rather than seeing what's left at the end of the month and trying to save that, a fixed amount moves into savings the moment your salary lands, before you've had the chance to spend it.
I'd recommend setting this up as a percentage of income you can comfortably sustain rather than an arbitrary round number, and revisiting it every few months as your situation changes. The mechanism doesn't care how much you set; it just runs the rule consistently.
What about an ISA?
Monzo offers access to savings products including Cash ISAs, often through partner banks inside its savings marketplace rather than as a fully Monzo-branded product. This matters because it changes who's actually holding your money and what protections apply, so it's worth reading the specific product details in the app before committing, rather than assuming every option works identically.
If you're looking specifically for a Stocks and Shares ISA, that's a different kind of product entirely, and Monzo's ISA focus has historically sat on the cash side. Check what's currently available directly in the app, since providers add and remove products over time, and I'd rather send you to the live, accurate list than print a snapshot here that goes stale.
Practical setup tips
Start by creating one pot for your emergency fund before anything else. Three to six months of essential costs is the usual target, and having it sit separately from your spending balance makes a real psychological difference. Once that's underway, layer in a payday transfer for a specific goal, and switch on round-ups across your main spending — it costs you nothing to leave running and quietly compounds your savings rate over the months.
If you've got multiple goals, resist cramming them all into one pot. Separate pots for separate goals keep your progress visible and stop one goal's money quietly subsidising another when you're not paying close attention.
Reviewing and adjusting over time
The mistake I see most often isn't failing to set anything up — it's setting it up once and never revisiting it. A payday transfer that made sense a year ago might be too small now your income's gone up, or too aggressive if your costs have changed. I'd suggest a quick review every three to six months: check each pot's progress against its goal, check the interest rate currently on offer if you're holding a meaningful balance, and adjust your round-ups or scheduled transfers if your circumstances have shifted.
This is also the point to check whether a better savings rate has appeared elsewhere in the app's marketplace, or whether a Cash ISA makes more sense for part of your savings depending on how much interest you're likely to earn and your tax position. None of this needs to take long, but treating your savings setup as something you check in on periodically, rather than something you configure once and forget, tends to produce noticeably better results over a few years.
Where savings pots fit against bigger financial goals
It's worth being honest about what pots are good for and what they're not. They're excellent for short-to-medium-term goals: emergency funds, a known upcoming cost like a holiday or a car, or general buffer money you want kept separate from spending. They're less suited to long-term growth, because even with interest, cash sitting in a pot won't compound the way a diversified investment can over ten or twenty years.
If you've already got a solid emergency fund built up in pots and you're saving beyond that for something further out, like retirement or a goal that's many years away, it's worth looking at whether some of that money would do more for you in a Stocks and Shares ISA or pension rather than sitting entirely in cash. Monzo's strength is the everyday savings layer — the buffer and short-term goals — and it's one part of a complete picture rather than the whole thing.
My take
Monzo's savings tools aren't flashy, and that's the point. Pots, round-ups, and scheduled transfers do the unglamorous work of making saving automatic, which matters far more for most people's actual outcomes than chasing the best interest rate on the market. Set the structure up once, check it every few months, and let it run.
