Frequently asked
How much of my income should I spend on a car?
A common rule of thumb is to keep total car costs — finance, fuel, insurance, tax and servicing — under 15–20% of your net monthly income. Beyond 25% you're in stretch territory: any dip in income or unexpected bill makes payments hard.
Do lenders use this same calculation?
Lenders run their own affordability assessment based on bank statements, credit file and ONS expenditure benchmarks. This tool gives an honest self-check before you apply — it doesn't guarantee approval, but it stops you overreaching.
Why does the maximum borrow change when I move the term?
Longer terms spread the same principal over more months, so the monthly payment drops and you can borrow more within the same budget. You'll pay more interest overall though — that's the trade-off.
Should I include my partner's income?
Only include income you actually control. For a joint application you can combine incomes and shared commitments. For a sole application, use only your figures.
