We're Here to Help With Your Car Budget Questions

A common guideline is the 20 4 10 rule: 20% down payment, finance for no more than 4 years, and keep monthly finance payments plus car insurance costs and car running costs under 10% of gross income. The 10 15 income rule suggests total transport costs shouldn't exceed 10-15% of your take-home pay.

Beyond the purchase price, your realistic car budget should include monthly finance payments, car insurance costs, fuel, maintenance, MOT, road tax, parking, and depreciation. Use a car budget calculator to accurately calculate car budget including all monthly car costs for true practical vehicle budgeting.

The biggest car budgeting mistakes include focusing only on the purchase price, ignoring car running costs, overextending on monthly payments, skipping the new vs used car budget comparison, not understanding different car finance options, and failing to plan for unexpected repairs when creating your car purchase budget.
