Hidden Costs of Car Finance You Need to Know

Summary

• APR is what matters, not the monthly payment: A longer deal means lower payments but more total interest.
• Excess mileage charges add up fast: PCP deals charge 5–20p per extra mile. That can be hundreds of pounds.
• Early exit fees exist: Ending a deal early often costs more than you think. See our early termination guide.

Car finance makes cars affordable. But the advertised monthly payment rarely tells the whole story.

Here are the hidden costs that catch people out.

The Total Interest You'll Pay

A low monthly payment feels good. But spread over 4–5 years, the total interest can be shocking:

Deal	Monthly Payment	Total Paid Over 4 Years	Total Interest
£15,000 at 5% APR	£345	£16,560	£1,560
£15,000 at 12% APR	£395	£18,960	£3,960
£15,000 at 25% APR	£470	£22,560	£7,560

Always check the total amount payable — not just the monthly figure.

Excess Mileage Charges (PCP)

PCP deals set a maximum annual mileage — usually 8,000–12,000 miles. If you go over, you pay a penalty per extra mile:

• Small cars: 5–8p per mile
• Medium cars: 8–12p per mile
• Premium/luxury cars: 15–30p per mile

If you drive 2,000 miles over your limit at 10p per mile, that's £200 extra per year — £800 over a 4-year deal.

Damage and Condition Charges (PCP and Leasing)

When you return a car on PCP or a lease, it's inspected for damage. The BVRLA (British Vehicle Rental and Leasing Association) fair wear and tear guide sets the standard. Beyond that:

• Scratches longer than 25mm: £75–£250 each
• Dents: £50–£150 each
• Alloy wheel damage: £75–£200 per wheel
• Interior stains or burns: £100–£300
• Missing items (spare tyre, parcel shelf): £50–£200

Early Settlement Fees

Want to end your deal early? You'll usually need to pay:

• The remaining balance: All future payments (minus a rebate for interest you won't be charged).
• Settlement fee: Some lenders charge an admin fee of £50–£200.

You do have the legal right to voluntary termination if you've paid 50% or more. See our voluntary termination guide.

Option to Purchase Fee

If you want to keep the car at the end of a PCP deal, you'll pay a balloon payment PLUS an option to purchase fee. This is usually £100–£200 on top.

Many buyers forget about this fee until the end of the deal.

How to Protect Yourself

1. Read the full agreement: Don't just look at the monthly payment.
2. Compare APRs: Lower APR = less total interest.
3. Be realistic about mileage: Choose a mileage limit that matches your actual driving.
4. Look after the car: Fix minor damage before returning to avoid condition charges.
5. Check for finance on used cars: Use our car history check to see if a used car has outstanding finance before buying.

The cheapest monthly payment isn't always the best deal. Focus on the total cost, not the monthly figure.
