Most budgeting apps will show you a monthly payment figure. Very few will show you what a loan actually costs in total. That gap matters more than it might first appear, and it is worth understanding before you use an app to decide whether you can afford to borrow.
What does the guidance say?
MoneyHelper, the UK's free money guidance service, notes on its Borrowing money pages that borrowers should consider the total cost of credit rather than the monthly repayment alone (accessed June 2026). The FCA's consumer credit pages set out that consumers should look at "the total amount payable" when comparing credit products, as this reflects the full cost of borrowing rather than just the periodic payment (accessed June 2026).
Both sources reinforce three points:
- Budgeting apps typically show your monthly payment for a loan or credit card, not the total you will repay over the life of the agreement.
- The total amount repayable can be significantly higher than the sum you borrowed, depending on the interest rate and the repayment term.
- Representative APR figures are a starting point for comparison, but the rate you are actually offered may differ based on your credit history.
Why does this matter?
A simple example helps. Suppose you borrow £5,000 at a representative APR of 9.9% over five years. Your monthly payment might appear manageable in a budgeting app. But the total amount repayable over that period could be around £6,300. This is an illustrative figure only; your actual total will depend on the rate you are offered and the term you choose. You can check figures for your own scenario using the loan repayment calculator. On these illustrative numbers, you would pay roughly £1,300 in interest charges.
A shorter term would reduce the total interest paid but increase the monthly payment. A longer term does the opposite.
The important bit is that a budgeting app showing you a comfortable monthly figure does not mean borrowing is cheap overall.
How do UK budgeting apps handle borrowing costs?
Several widely used apps approach this differently, and it is worth knowing what each one does and does not show you. Features and functionality change over time, so the descriptions below reflect what was available at the time of writing. Always check each app's own help documentation to confirm current features: Emma Help, Snoop Help, Monzo Help, Starling Help, YNAB Help. Features correct as of June 2026.
Emma connects to your accounts via open banking and can pull in live loan and credit card balances automatically. It displays outstanding balances and monthly payments, but does not calculate total interest payable over the remaining term.
Snoop also uses open banking to aggregate accounts. It focuses on spending patterns and bill comparisons. Loan cost breakdowns beyond the monthly figure are not a core feature.
Monzo (used as a current account with a Monzo loan) shows your monthly repayment and remaining balance within the app. It does not prominently surface the total amount repayable across the full term in the main budgeting view.
Starling Bank similarly displays loan repayments as a line in your spending breakdown. The total cost of the loan over its lifetime is not shown in the budgeting summary.
YNAB (You Need A Budget) takes a manual-entry approach rather than open banking. You record loan repayments yourself, which means the app reflects only what you tell it. It does not calculate interest costs independently.
The practical implication is consistent across all of these: the monthly figure is visible; the total cost of credit generally is not. A useful first step is to use a dedicated loan calculator alongside whichever app you prefer, rather than relying on the app's repayment line alone.
Who may be affected?
This is most relevant if you:
- Use a money management app to decide whether you can "afford" a new loan or credit card.
- Compare loan options based on monthly cost rather than total amount repayable.
- Are considering extending a repayment term to reduce monthly outgoings (which lowers the monthly figure but increases total interest).
- Have a variable-rate loan or credit card, where the monthly figure in your app may change if interest rates move. For example, if you have a £10,000 variable-rate personal loan and the rate rises by one percentage point, your monthly payment and total interest bill both increase, but the app's displayed figure may not update until your lender recalculates and the change appears in your transaction data.
The Bank of England base rate influences many variable-rate lending products. When the base rate changes, the monthly figure shown in your app may not update automatically.
If you use an app and discover that your existing borrowing is already stretching your budget, free and impartial debt-help services are available. StepChange and National Debtline both offer confidential advice at no cost.
Frequently asked questions
Does Monzo show the total cost of a loan? Monzo displays your monthly repayment and outstanding balance for a Monzo loan, but the total amount repayable over the full term is not prominently shown in the budgeting summary. It can help to check your original loan agreement or use a repayment calculator to see the full cost.
Which budgeting app is best for tracking loan repayments in the UK? No single app stands out as purpose-built for loan cost tracking. Emma, Snoop, and Monzo all pull in live balances via open banking, which reduces manual entry. However, none of them calculate total interest payable as a headline figure. A useful approach is to pair any of these apps with the loan repayment calculator for a complete picture.
What is the difference between open banking apps and manual budgeting apps for loans? Apps that use open banking (such as Emma, Snoop, Monzo, and Starling) can pull your live loan balance and repayment transactions directly from your lender, so the figures stay current without manual input. Apps like YNAB rely on you entering figures yourself, which gives you more control but requires discipline to keep up to date. Neither type automatically calculates the total interest you will pay over the remaining term.
