PCP vs HP vs Personal Loan: Which Car Finance Actually Costs Less?

The real maths behind car finance options in the UK. Calculate total costs, hidden fees, and which option makes sense for your situation.

You've found the perfect car. £25,000. The dealer offers you three ways to pay. They all sound reasonable. They're all wildly different in total cost.

Let's do the maths the dealer won't show you.

The Three Main Options

Personal Contract Purchase (PCP): Low monthly payments, balloon payment at the end Hire Purchase (HP): Higher monthly payments, you own the car at the end Personal Loan: Borrow from a bank, pay cash to the dealer

Same car. Same price. Very different outcomes.

PCP: The "Affordable" Illusion

PCP is the UK's most popular car finance. Here's how it works:

Example: £25,000 car on PCP

  • Deposit: £2,500 (10%)
  • Monthly payment: £299 for 48 months
  • Final "balloon" payment: £10,500
  • APR: 8.9%

Total you'll pay:

  • Deposit: £2,500
  • Monthly payments: £299 × 48 = £14,352
  • Balloon payment: £10,500
  • Total: £27,352

Cost of finance: £2,352

But wait. Most people don't pay the balloon. They hand the car back and start a new PCP. Which means:

  • You paid £16,852 over 4 years
  • You own nothing
  • You're back at square one

PCP is essentially a 4-year rental with extra steps.

HP: The Straightforward Option

Same car, Hire Purchase:

Example: £25,000 car on HP

  • Deposit: £2,500 (10%)
  • Monthly payment: £512 for 48 months
  • Final payment: £0 (you own it)
  • APR: 7.9%

Total you'll pay:

  • Deposit: £2,500
  • Monthly payments: £512 × 48 = £24,576
  • Total: £27,076

Cost of finance: £2,076

At the end, you own the car outright. No balloon payment decision. No pressure to get a new deal.

Personal Loan: The Hidden Winner?

What if you got a loan from your bank instead?

Example: £22,500 personal loan (after £2,500 deposit)

  • Interest rate: 6.9% APR
  • Monthly payment: £538 for 48 months
  • Total repayment: £25,824

Add your deposit back:

  • Deposit: £2,500
  • Total: £28,324

Wait, that's more expensive? Sometimes. But here's the thing:

Advantages of personal loan:

  1. You're a cash buyer - negotiate £1,000-£2,000 off the price
  2. No mileage limits
  3. No condition penalties
  4. You can sell anytime without permission
  5. Better rates if you have good credit

If you negotiate £2,000 off as a cash buyer:

  • Car price: £23,000
  • Loan needed: £20,500
  • Total repayment: £23,547
  • Add deposit: £26,047

Suddenly it's the cheapest option.

The Mileage Trap

PCP contracts have mileage limits. Typical allowances:

  • 8,000 miles/year
  • 10,000 miles/year
  • 12,000 miles/year

Exceed them? You'll pay 8p-15p per mile.

If you do 15,000 miles/year on a 10,000 mile contract:

  • Excess: 5,000 miles × 4 years = 20,000 miles
  • Penalty at 10p/mile: £2,000

That "cheap" PCP just got expensive.

Average UK mileage: 7,400 miles/year But: Commuters, salespeople, and parents of teenagers do far more

The Condition Catch

Return a PCP car with damage beyond "fair wear and tear" and you'll be charged.

Common charges:

  • Alloy wheel scuff: £50-£100 per wheel
  • Dent larger than 15mm: £75-£150
  • Interior stain: £100+
  • Windscreen chip not repaired: £75

These add up. Budget £200-£500 for "return condition" costs on most PCP deals.

The Depreciation Reality

Here's what actually makes the decision:

New car depreciation:

  • Year 1: 15-35% (ouch)
  • Year 2: 10-15%
  • Year 3: 10-15%
  • After 3 years: 40-60% of value gone

PCP lets you:

  • Avoid owning a rapidly depreciating asset
  • Always drive a relatively new car
  • Never deal with major repairs (warranty covers it)

HP and loans mean:

  • You eat the depreciation
  • But once paid off, you have a free-to-run asset
  • Years 5-8 of ownership are the cheapest per mile

The Real Question

Choose PCP if:

  • You want a new car every 3-4 years
  • You drive predictable, low miles
  • You can't afford HP payments
  • You accept you'll always have a car payment

Choose HP if:

  • You plan to keep the car 5+ years
  • You want to own something
  • You might do high miles
  • You can handle higher monthly payments

Choose a personal loan if:

  • You have good credit (lower rates)
  • You want negotiating power
  • You might sell before the term ends
  • You hate being tied to a dealer

The "Just Lease It" Alternative

Company car or personal lease? Different calculation entirely.

Personal Contract Hire (PCH):

  • Monthly payment, return the car, done
  • No balloon decision
  • No depreciation gamble
  • You never own anything

For some people, this simplicity is worth paying extra.

Running the Numbers Yourself

Before you sign anything:

  1. Calculate total cost - Not monthly payment. TOTAL.
  2. Add all fees - Arrangement fee, option-to-purchase fee, excess mileage estimates
  3. Compare to buying used - A 2-year-old car is 30-40% cheaper
  4. Factor in your actual miles - Be honest
  5. Consider how long you'll keep it - 3 years? 7 years? Forever?

The dealer wants you focused on "£299/month sounds affordable."

The question is: affordable compared to what?


Use the loan calculator above to compare your options. Then sleep on it. Car finance is a 4-year commitment that shouldn't be made in a showroom.
