The Best Budgeting Apps (At a Glance)

The table below shows a snapshot of some of the best budgeting apps in the UK. The fees listed here are not exhaustive; other fees may apply. Scroll down for a more detailed comparison.

The Best Budgeting Apps in the UK (In Detail)

The best budgeting apps in the UK are Koody, PocketSmith and Plum. Koody is an AI budgeting app that builds a budget around your payday and answers questions about your spending, such as “How much have I spent on groceries since payday?” PocketSmith offers bank connections with detailed reporting and cash flow forecasts. Plum helps you save automatically.

We also compare Emma, Monzo and Monese. The six apps differ in how they record spending, how they help you plan ahead and whether you need a paid plan for the features you want.

With your permission, a connected app can show transactions from supported accounts. A manual tracker lets you decide what to record and when. If you prefer a larger screen for planning, check the availability column before choosing.

Here are the best budgeting apps in the UK:

Koody - AI-powered payday budgeting and spending tracking

Cost
Free to £4.99/month

(Import transactions or log manually)

Bank Connection

Availability
Desktop, iOS, and Android

Koody is our first pick for AI-powered payday budgeting. You can track income, spending and bills across accounts without linking them to the app. Ask Koody AI to build a budget around your payday or show which purchases pushed up your grocery spending. You can track your current account, savings, credit cards and cash in one place, even if they’re spread across different providers. Start with the free spending tracker on your phone or desktop: enter your pay, log your purchases and keep an eye on subscriptions and upcoming bills. It’s particularly useful if you pay for some things in cash and want those purchases to count towards the same budget as your card spending.

Where Koody really comes into its own is payday budgeting. Say you’re paid on the 25th. Your rent is due on the 1st, your train pass renews on the 12th and you need your grocery money to last until the 24th. Set a budget that starts when you get paid, then check how much is left in each category as the month unfolds. For a one-off expense like a holiday, give Koody AI your total and ask it to split the money between travel, accommodation and meals.

If you’ve fallen behind, you can catch up without typing in every purchase. Koody Plus, the app’s £4.99-a-month subscription plan, lets you import bank and credit card statements as CSVs or PDFs. Koody sorts transactions into categories and checks for transactions you’ve already imported. Review the results, then compare months to see whether a jump in spending was a one-off bill or the beginning of a pattern. You control when each account is updated.

Choosing a Koody plan. The free plan covers manual tracking, bills, receipts and up to a year of spending history. Standard (£2.99/month) adds recurring budgets, payday alignment, custom categories and exports. Plus (£4.99/month) adds statement imports, automatic categorisation and unlimited history. For someone who wants a weekly spending check and a plan that lasts until payday, Standard is the natural step up. Choose Plus if importing statements would save you time each month.

PocketSmith - Detailed reporting and future projections

Cost
Free; paid from US$9.99/month billed annually

Bank Connection

Availability
Desktop, iOS, and Android

PocketSmith is a strong choice if your main question is what your balance will look like on a particular date. Its budget calendar puts income and expenses on the days you expect them. Add your monthly pay, regular bills and a car insurance renewal, for example, and you can see whether the renewal lands in a week when money is tight. Move a planned purchase to the following payday and compare the projected balances before deciding when to buy.

The free plan gives you two accounts, 12 budgets and a six-month forecast. That’s enough to model a current account and a credit card manually and see how the calendar fits your routine. Collaborator access is useful for a household: you can invite a partner to review the figures using their own login. Reports and category rules help you look back at what actually happened as well as plan ahead.

Choosing a plan. Foundation adds automatic feeds for up to six banks in one country and extends the forecast to ten years. It costs US$14.95 when billed monthly, or US$9.99 per month billed annually. Flourish is worth comparing if your accounts span more than one country. Check coverage for your own bank before paying, and remember that the sterling cost depends on the exchange rate. A forecast is only as reliable as the pay dates and expenses you enter.

Plum - Smart budgeting and automated savings

Cost
Free to £14.99/month

Bank Connection

Availability
iOS and Android

Plum suits people who intend to save whatever is left at the end of the month, then find there’s rarely anything left. Connect a supported bank and choose a saving rule. One option is Round-Ups: if you spend £6.40, the rule earmarks 60p. Plum adds the previous week’s round-ups together and deposits the total once a week, so you can recognise the single collection on your statement.

Another option, Pound-Ups, can set aside £1 on a whole-pound purchase that would otherwise generate no round-up. That distinction matters if you often spend whole amounts on travel or lunch. Look at a typical week’s purchases before switching on a rule, especially if several bills leave your account just before payday. With Plum, the benefit is that a decision you make once can turn everyday spending into a regular saving habit.

Choosing a plan. New UK customers can start with Basic for free. The monthly alternatives are Plus (£3.99), Boost (£7.99) and Max (£14.99). Check which rules and features come with the plan you’re considering. If one rule is all you’ll use, compare the subscription cost with what you expect to set aside. Existing customers may see a legacy subscription in the app.

Emma - Spending tracker and net worth calculator

Cost
Free to £14.99/month

Bank Connection

Availability
iOS, Android and web (paid plans)

Emma is useful when you need several statements to answer the question ‘Where did my pay go?’. It brings transactions and balances from supported accounts into one view and helps you spot recurring payments. For example, your broadband bill might come from your current account while three streaming subscriptions sit on a credit card. Reviewing those payments together makes it easier to decide which ones you still use.

Choose the subscription around the accounts and tools you actually need. Plus supports four bank logins and includes budgeting tools and web access. Pro adds unlimited supported bank logins, custom categories, CSV imports, exports and net worth tracking. If you want a category just for commuting, or want to take your records back into a spreadsheet, those are concrete reasons to consider Pro.

Choosing a plan. Start with the free version to see how your transactions appear. Plus is £4.99 a month, Pro £9.99 and Ultimate £14.99. Ultimate adds Spaces and business-account support, which may suit someone keeping different parts of their finances separate. Check that Emma supports the accounts you plan to connect before choosing a tier.

Monzo - Full banking service with budgeting features

Cost
Free; Extra £3/month

Bank Connection

Availability
iOS and Android

Monzo makes budgeting part of using your current account. When your salary arrives, you can move the money for rent, groceries or a weekend away into separate Pots. A £900 rent payment can sit apart from your everyday spending balance, so a glance at the app gives you a better idea of what is available for the rest of the week.

The free current account is a useful starting point and lets you connect one external bank account or credit card. Extra goes further with unlimited supported connections, custom spending categories and virtual cards. You could link a virtual card to a grocery Pot and use that card for the weekly shop. You can also export transactions automatically to Google Sheets if you already manage part of your budget in a spreadsheet.

Choosing a plan. Extra is £3 a month and is the upgrade to compare for these budgeting tools. If Pots already do the job, you can keep using the free account. Monzo is particularly convenient if you want the account you spend from and the place you organise your bills to be the same app.

Monese - Spending analysis and savings pots

Cost
Free to £14.95/month

Bank Connection
Monese account

Availability
iOS and Android

Monese is worth a look if you want a mobile spending account with a simple way to earmark money. Use its money pots to put aside the cost of an upcoming expense, then turn on round-ups if you want small card purchases to contribute as well. A pot for an annual travel pass, for instance, gives those savings a purpose and keeps them separate from the money you expect to spend this week.

Monese offers accounts in GBP, EUR or RON, and a joint account with another Monese user. That makes it an option for two people who want a dedicated place for shared spending. If you regularly send money, use cash machines or pay by card in another currency, compare those specific fees. The lowest monthly subscription doesn’t necessarily give you the lowest total cost.

Choosing a plan. Pay As You Go has no monthly subscription. On its UK fee schedule, a bank transfer out costs £1.29 on that plan. Everyday costs £2.95 a month and includes two outbound transfers per month. Cashback is £7.95 a month and Premium £14.95. Use last month’s transfers and withdrawals to work out which plan would have cost you less.

What Is a Budget?

A budget is essentially a financial plan that helps you manage your income and expenses over a period of time, usually monthly. Think of it as a roadmap for your money. Just like you wouldn't go on a long journey without a map (or a GPS!), having a budget keeps you on track with your financial goals and helps ensure you're not spending more than you're bringing in.

Creating a budget means looking at how much money you have coming in (your income) and where it's going (your expenses). This process makes it easy to spot areas where you might be overspending or places where you could save a bit more. With this knowledge, you can make adjustments that bring you closer to achieving important financial milestones such as paying off debt, saving for a house deposit, or building up an emergency fund for life's surprises.

For example, let's say you take home £2,000 a month after taxes, National Insurance, and other statutory payments. You'll want to make sure that your total spending doesn't go above that amount. Spending more than you earn can lead to financial stress and problems that affect not only your wallet but also your mental health. A good budget helps you plan your spending so you don't run out of money before your next payday. And if you stick to it, you might even have some left over for savings or investing in your future.

How to Create a Budget

There are many ways to create a budget, and it is important to find what works best for you. If you already keep track of your earnings and spending, you're already on your way to having a budget. However, if you're new to budgeting, it might help to follow a simple rule or guideline.

At ISACalculator.com, we suggest using the 50/30/20 rule as a starting point. This method divides your monthly income into three categories:

50% goes towards needs such as rent, groceries and utilities.

30% goes towards wants, such as eating out, entertainment and shopping for non-essentials.

20% goes towards savings and debt repayments above the minimum.

To make this clearer, let's continue with the example of earning £2,000 a month. Under the 50/30/20 rule, you'd put £1,000 towards your essential needs, £600 towards your wants, and £400 into savings or paying off debt. If your essential bills already exceed £1,000, use your actual costs and adjust the split to fit. Try our 50/30/20 budget calculator to see the figures for your take-home pay. Our calculator lets you compare your monthly and annual 50/30/20 budget breakdowns.

The Three Main Budget Categories

When building a budget, it is helpful to break your spending into three main categories:

Needs (50%)

Needs are the things you can't live without. These include:

1. Groceries
2. Rent or mortgage payments
3. Utilities (electricity, water, broadband, phone bills)
4. Transport costs
5. Healthcare
6. Insurance
7. Minimum debt repayments (anything extra goes into the "savings and debt" category)

The 50% figure is a starting point. If housing or transport takes up more of your pay, budget for those costs first.

Wants (30%)

Wants are the extras that make life more enjoyable but aren't strictly necessary. These could be:

1. Going out to eat or ordering takeaways
2. Gym memberships
3. Travel and holidays
4. Shopping for non-essential items like party clothes, gadgets, or entertainment

It is important to spend money on things that bring joy, but setting a 30% limit helps keep things in check. Depending on your situation, you may find that 30% is too high, and that's fine. This is a flexible framework.

Savings and Debt (20%)

This is the category that prepares you for the future. It covers:

1. Building an emergency fund
2. Saving for long-term goals like retirement, buying a home, or even big expenses like weddings
3. Paying down debt faster than the minimum payments require

An emergency fund can help cover an unexpected expense or a gap between paydays. MoneyHelper suggests three to six months of essential outgoings as a rule of thumb. Start with what you can afford after bills and required repayments.

Top Budgeting Methods

While the 50/30/20 rule is a great starting point, it's not the only way to manage your money. Different people find success with different methods:

1. Zero-Based Budgeting: This method involves allocating every pound of your income to a specific category, leaving nothing unaccounted for by the end of the month. It is great for people who like a detailed, structured plan, but it can take time and discipline to maintain.
2. Envelope System: Popular in a more cash-based world, this method involves setting aside money for specific categories (e.g., rent, groceries, entertainment) in physical envelopes. Once an envelope is empty, you can't spend more in that category until next month. Today, many digital banking apps allow you to replicate this method virtually.
3. Pay Yourself First: With this approach, you prioritise savings by setting aside a specific amount as soon as you get paid before covering other expenses. It's a great way to ensure your savings grow, but it requires a bit of flexibility to handle unexpected costs.
4. Value-Based Budgeting: This method helps align your spending with what truly matters to you. It is less about rigid categories and more about making sure your money supports your personal values, whether that's travel, education, or investing in hobbies.

The key to successful budgeting is finding the method that best suits your lifestyle and financial goals. There's no "one-size-fits-all" solution.

1. Are budgeting apps safe to use in the UK?

Check who provides the bank connection, which accounts the app can access and how to withdraw permission. Access to read transactions is different from permission to initiate payments. For a manual tracker, check how it stores any statements or transactions you upload.

2. What are the best free budgeting apps in the UK?

Koody Free lets you record income and expenses, track bills and ask Koody AI about your spending. Creating recurring payday budgets is a Standard feature. PocketSmith Free is useful for a six-month forecast across two accounts. If you already bank with Monzo, you can use Pots to organise your spending without a monthly subscription.

3. How does Open Banking work with budgeting apps?

Open Banking allows you to link your bank accounts to budgeting apps, giving them access to your financial data to provide an overview of your spending and financial habits. Apps like Plum and Emma use Open Banking to pull transaction data from your bank and help you manage your finances in one place.

4. How should a beginner start saving money with a budgeting app?

To start saving money, use a budgeting app that tracks your spending and suggests where you can cut back. Set clear financial goals, create savings categories, and automate your savings using a standing order or direct debit. Alternatively, you can use an app like Plum, which can automatically move money into a savings pot based on your spending patterns.

5. What is the best budgeting app for couples or families in the UK?

Koody suits a household that wants to build a budget around payday. On Standard, you can create categories for shared costs such as groceries and bills, then check what remains before the next shop. If each partner needs their own login to review the same figures, PocketSmith offers collaborator access.

6. Why do some budgets fail?

Budgets can fail for several reasons, including setting unrealistic goals, not accounting for unexpected expenses, and choosing a budgeting tool that's too complicated or time-consuming. It's important to set manageable financial goals, track both regular and ad hoc expenses, and use a user-friendly app that works for your lifestyle.

7. How can I avoid going over budget?

Add up the bills due before your next payday, then divide the money left for everyday spending by the number of weeks it needs to last. Check your spending after the first week. If groceries cost more than expected, adjust another category while there is still time to do so.

8. Which budgeting app is best for tracking investments in the UK?

Emma Pro and Ultimate include net worth tracking. Check whether Emma supports your investment provider before subscribing. A budgeting app can help you follow changes in your overall balance. For the performance of individual investments, use your investment provider’s statement.

9. Can budgeting apps help with debt management?

Yes. Enter repayment dates and amounts in your budget so you can see which bills fall due before payday. PocketSmith’s calendar helps you forecast your balance after repayments. In Koody, a dedicated budget category can help you track what you have set aside for them.

10. Which budgeting apps are best for saving on bills in the UK?

Use Emma to spot recurring charges across supported accounts, or a Monzo Pot to reserve money for bills before they fall due. These tools help you see what you pay. To find a cheaper tariff, compare the bill itself with quotes from suppliers.
