How much you can finance: the 30% rule
There is no fixed maximum amount that all banks apply equally. What does exist is a payment capacity criterion that almost all institutions use as a reference: the monthly loan payment should not exceed 30% of your net monthly income.
This does not mean that if you earn £2,000 net you can have a monthly payment of £600 without any problem. It means that this is the guideline limit that institutions use to assess risk. If you have more fixed expenses (rent, mortgage, other loans), the real margin is smaller.
The most prudent rule is this: the sum of all your monthly debts should not exceed 35-40% of your net income. This percentage includes the car payment, the mortgage or rent if you pay it yourself, credit cards, other loans and any other monthly financial commitments.
How the bank calculates your borrowing capacity
When you apply for car finance, the lender analyses four main factors:
Net monthly income. The SMI (minimum wage) in 2026 is €1,221 gross per month. For finance to be viable, income usually has to exceed this threshold in a provable way. Job stability (permanent versus temporary contract, length of service with the company) carries as much weight as the figure itself.
Existing debt. If you already have a mortgage of £600 and a personal loan of £150, your margin for taking on the car payment is much narrower than if you had no debt. Lenders consult credit history (credit reference agencies, bad debtor files) to see what active debts you have.
Deposit paid. The more you put down as a deposit, the less risk the lender takes on and the more likely it is that the transaction will be approved, even with tighter income. A deposit of 20-30% of the car's value significantly improves the terms.
Vehicle value and age. For second-hand cars over 10-12 years old, some lenders limit the maximum amount or the term. Financing a new car with a manufacturer's warranty is not the same as financing a used one with 150,000 km and no warranty.
Guideline table: how much car you can finance according to your salary
This table shows the maximum guideline monthly payment (30% of net salary) and the approximate car value you could finance over 60 months at an APR of 7%, with no deposit and no other existing debts.
Net monthly salary | Guideline maximum monthly payment (30%) | Approx. financeable amount (60 months, APR 7%) |
|---|---|---|
£1,200 | £360 | ~£18,000 |
£1,500 | £450 | ~£22,500 |
£2,000 | £600 | ~£30,000 |
£2,500 | £750 | ~£37,500 |
£3,000 | £900 | ~£45,000 |
These amounts are guidelines for a profile with no previous debt. If you have other financial commitments, the actual amount you will be approved for will be lower. If you put down a deposit, the monthly payment goes down and you can access a higher-value car for the same monthly payment.
If you have issues on default registers, the article on financing a car with ASNEF explains what options exist and what conditions to expect.
What happens if you already have other debts
If you already have active debts, the bank does not just add the car payment on top of the 30%: what it does is calculate how much margin you have left within the overall 35-40% total.
A specific example: if you earn £2,000 net and have a mortgage of £500 (25% of your income), you only have between £200 and £300 margin left for the car payment (10-15%). With that margin, the financeable amount over 60 months at 7% APR would be between £10,000 and £15,000, not the £30,000 that would correspond to that salary with no debts.
If you have other active debts but want to finance a higher-value car, you have three options: put down a larger deposit to reduce the monthly payment, extend the term (which reduces the monthly payment but increases the total cost), or clear smaller debts before applying for car finance.
If the car you want to sell still has active finance, the article on selling a financed car explains how outstanding debt is managed in the transaction.
How much they finance in 2026: maximum percentage of the car's value
In 2026, most lenders allow you to finance up to 100% of the car's value, for both new and used cars. But just because it is possible does not mean it is recommended, nor that all lenders will grant it in practice.
For new cars, 100% financing is common, especially when arranged through the dealership or the manufacturer's finance company. For second-hand cars, some lenders limit the percentage to 80-90% of the valuation, especially for vehicles older than 5-7 years.
The maximum amount granted by each lender also varies. Bankinter allows up to €30,000. ABANCA up to €60,000. The final terms always depend on the applicant's profile.
For a £3,000 deposit on an £18,000 car, the total interest savings over 6 years can exceed £1,100 compared to financing 100%. Putting down a deposit does not just improve the terms: it reduces the overall cost significantly.
To understand what that percentage means in terms of actual cost, the article on what is the flat interest rate and APR in car finance explains it with concrete examples.
How to increase the amount you are approved for
If the bank's initial response does not cover what you need, there are several levers to pull before giving up:
Put down a larger deposit. Reducing the capital to be financed is the most direct way to improve the terms and increase the chances of approval. If you have a current car, selling it before applying for finance gives you that liquidity.
If you have a current car, the article on how to coordinate selling your old car with buying the new one explains the correct order to maximize the available deposit.
Extend the term. Going from 48 to 60 or 72 months reduces the monthly payment and can make it fit within the 30% limit. The total cost goes up, but the approved amount can be higher.
Clear small existing debts. A credit card with a £3,000 limit that you barely use still counts as potential risk in the bank's assessment. Cancelling it before applying for car finance can improve your profile.
Apply with an additional policyholder. If your own income is not sufficient, adding a joint applicant (partner, relative) adds their income to the calculation and can unlock higher amounts.
Compare between lenders. The criteria are not identical at all banks and finance companies. A rejected application at one bank does not mean it will be rejected at another. Comparing at least three options before assuming it is not viable is always recommended.
The role of the deposit: how it reduces the monthly payment and total cost
The deposit is the percentage of the car's price that you pay out of your own pocket before financing the rest. Its impact is twofold: it reduces the monthly payment and reduces the total cost of financing.
An example with real numbers:
Car costing £20,000, 7% APR, 60-month term.
With no deposit (financing £20,000): payment £396/month. Total paid: £23,760. Cost of financing: £3,760.
With a £4,000 deposit (financing £16,000): payment £317/month. Total paid: £19,020 + £4,000 deposit = £23,020. Cost of financing: £3,020.
The difference is £740 in total cost and £79 less in monthly payments. The larger the deposit, the more pronounced this difference is.
To find out how much you can put down as a deposit, the first step is to find out how much your current car is worth. Valuing it with real market data gives you a concrete figure before speaking to any bank.
Dealcar: sell your current car and use the money as a deposit
If you own a car, selling it before applying for finance has a direct impact on how much you can finance and under what conditions. A larger deposit means a lower monthly payment, lower total cost, and a higher chance of approval.

FAQs
How much can I finance for a car with a salary of £1,500?
With £1,500 net monthly and no other debts, the maximum guideline monthly payment is £450 (30% of salary). Over 60 months and with a 7% APR, that is equivalent to financing approximately £22,500. If you have existing debts, the actual amount will be lower.
Can they finance 100% of the car for me?
Yes, in 2026 most lenders allow you to finance up to 100% of the value of the vehicle, especially for new cars. For second-hand cars older than 5-7 years, some lenders limit the percentage to 80-90% of the valuation.
What happens if my finance application is rejected?
A rejection from one bank does not close all doors. Criteria vary between lenders: comparing at least three options is always recommended. Putting down a larger deposit, extending the term, or clearing smaller existing debts can improve your profile for a second application.
Is a deposit compulsory to finance a car?
It is not compulsory in most cases. 100% financing is possible. However, putting down a deposit reduces the monthly payment, the total cost and improves the terms of the loan. If you can put down between 20% and 30% of the car's value, the difference in the final cost is significant.
How long does it take for car finance to be approved?
It depends on the channel. Online finance companies can give an answer within 24 hours. Traditional banks take between 2 and 5 working days. Finance arranged through the dealership is usually the fastest, with a same-day response in many cases.
