Economy & financing glossary

A glossary of car-related finance terms — from car loans and depreciation to taxes and deposits.

APR (Annual Percentage Rate)
The most important and transparent figure when comparing car loans. It includes both interest rates, establishment costs, and all ongoing fees, showing you the total, true cost of the loan.
Depreciation
The amount the car loses in value over time and mileage. For almost all cars, this is the absolute largest and most expensive cost of car ownership.
Down payment / Deposit
The cash amount you pay upfront when buying the car. For a standard car loan, a deposit of at least 20% of the car's price is usually required to get the best interest rate.
HP (Hire Purchase)
A straightforward finance option where you pay a deposit and fixed monthly payments. You own the car once the final payment is made. No mileage restrictions, unlike PCP.
HPI check
A vehicle history check (by HPI or similar providers) that reveals outstanding finance, insurance write-offs, stolen status, and mileage discrepancies. Essential before buying a used car privately.
Loan term / Duration
The period (in months or years) over which your car loan must be fully repaid.
Outstanding finance / Debt
The debt that still needs to be paid off on the car from a previous owner. It is critical to check if there is registered outstanding finance on the car before buying privately, as the debt stays with the car – not the person.
PCP (Personal Contract Purchase)
The most popular form of car finance in the UK. You pay a deposit and monthly payments, then choose to make a final balloon payment to own the car, hand it back, or part-exchange. Mileage limits apply.
VED (Vehicle Excise Duty)
The annual tax for keeping a vehicle on the road, commonly called "road tax." For cars registered after April 2017, the first-year rate depends on CO2 emissions; after that, a flat standard rate applies. Zero-emission vehicles are currently exempt.
Vehicle tax / Road tax
The recurring tax you pay to the government for owning a car. The tax is typically calculated based on the car's CO2 emissions for newer vehicles, or fuel consumption for older vehicles.
