Negative equity car finance calculator UK

Negative equity on car finance in the UK means you owe more than your car is worth. This page explains the idea and how to use our car finance calculator to see what happens if you roll that shortfall into a new loan. The calculator below works for any loan amount—you can add the negative equity to the amount you need to borrow for your next car. Estimates only; not financial advice.

Your actual affordability and car finance options in the UK depend on your circumstances and the criteria of individual UK lenders. Always check real quotes from lenders or speak to a regulated financial adviser before committing.

How to use the calculator for negative equity

To model rolling negative equity into a new car loan: work out how much you are short (settlement figure minus current car value). Add that to the amount you need to finance for the new car (new car price minus deposit). Use the calculator with that combined amount as the "car price" and your deposit as zero, or enter the new car price and set deposit to minus your negative equity if the calculator allowed—since ours uses price minus deposit, enter new car price + negative equity as the car price and your actual deposit as the deposit. The result is the finance amount and monthly payment for the combined loan.

Alternatives to rolling negative equity

Before adding negative equity to a new loan, consider whether you can pay off some or all of the shortfall with savings, or wait until you are closer to positive equity. Rolling it in is convenient but increases your new loan and the total interest you pay. Some lenders may not accept negative equity or may limit how much you can add. Check with UK lenders or a broker what options you have and compare the total cost of rolling the debt versus paying it down first.

Tip: to include negative equity, add the shortfall to the car price above (e.g. £18,000 new car + £2,000 negative = £20,000) and use your real deposit. The "finance amount" will then reflect borrowing for the car plus the negative equity.

Frequently asked questions

  • What is negative equity on car finance in the UK?

    Negative equity means you owe more on your car finance than the car is currently worth. It often happens when you want to change car before the loan is paid off, or when the car's value has dropped faster than your repayments. In the UK, some lenders let you roll this shortfall into a new finance agreement, but it increases what you borrow.

  • How can a negative equity car finance calculator UK help?

    A calculator helps you see what happens when you add negative equity to a new loan. You can enter the new car price plus the amount you are in negative equity as an extra amount to finance, then see the resulting monthly payment and total cost. Our main car finance calculator can be used by treating the total amount you need to borrow (new car minus deposit plus negative equity) as the finance amount.

  • Should I roll negative equity into a new car loan?

    Rolling negative equity into a new UK car finance deal increases your debt and monthly payment. It can be convenient if you need to change car, but you will pay more overall. Consider paying off some of the shortfall first, or waiting until you are in positive equity, if possible. This is not financial advice—speak to a lender or adviser.

  • Do all UK lenders accept negative equity?

    No. Not all UK car finance lenders will allow you to add negative equity to a new agreement. Rules and limits vary. Our calculator is for illustration only; you must check with lenders what they offer.
