Car finance advertising leads with monthly payments, and PCP dominates because its monthly figure is the lowest. But the monthly payment is only one part of the cost. PCP defers a large portion of the vehicle price as a balloon payment at the end, which means the total cost if you want to keep the car is often higher than Hire Purchase or a personal loan for the same amount. The question is not which option has the lowest monthly payment but which one costs least for the outcome you actually want.

This tool compares all three finance structures on the same vehicle price, deposit, and term, showing the monthly payment, total cost, total interest, and what you own at the end under each option. It also models the balloon payment decision on PCP and uses illustrative depreciation to show whether the car is likely to be worth more or less than the balloon at the end of the agreement. All figures are illustrative and depend on the inputs you provide.

About this tool

How to use the car finance comparator

The comparison is most useful when the APR figures reflect what you would actually be offered. Manufacturer PCP and HP rates are often promotional and depend on the specific model and deal. Personal loan APRs depend on your credit profile. Using indicative or representative rates gives a broad comparison; using actual quoted rates gives a precise one.

How PCP works and what you are actually paying for

A PCP agreement finances the difference between the vehicle price (minus deposit) and the balloon payment, not the full amount. The monthly payments cover this depreciation portion plus the interest charged on the total credit amount. At the end of the agreement, you have three options: return the car with nothing further to pay (subject to condition and mileage limits), pay the balloon amount to own it outright, or use any equity above the balloon as a deposit on a new PCP deal. The structure is designed to produce a lower monthly payment than HP or a personal loan, which is why PCP dominates car finance advertising.

The trade-off is that the total cost of ownership under PCP is typically higher than under HP or a personal loan at the same APR, because interest accrues on the full credit amount including the deferred balloon. The balloon sits on the balance throughout the agreement, generating interest each month even though it is not being paid down. This means the total interest on a PCP deal is higher than on an HP deal at the same rate for the same vehicle, because the HP deal reduces the principal month by month while the PCP deal keeps the balloon portion outstanding for the full term. The comparison in this tool makes this difference visible in total cost and total interest terms.

The balloon payment decision at the end of PCP

The balloon payment is the amount you would need to pay to own the car at the end of the PCP agreement. Whether it makes financial sense to pay it depends on two things: what the car is worth at that point, and whether you have access to the funds or would need to borrow again to cover it. If the car is worth more than the balloon, you have positive equity: you can pay the balloon and own a car worth more than you paid, or trade the equity into a new deal. If the car is worth less than the balloon, you have negative equity: paying the balloon means paying more than the car is worth, and returning it is the more rational financial choice.

The depreciation panel in the tool estimates the car value at the end of the term using a simplified 15% annual depreciation rate and compares it to the balloon. This is illustrative: actual depreciation varies significantly by make, model, mileage, condition, and market conditions. Some vehicles hold their value better than others, and the GMFV set by the finance provider is designed to be conservative (below the expected market value) so that positive equity is the more common outcome. The panel shows whether the illustrative figures suggest positive or negative equity, which is a starting point for thinking about the balloon decision rather than a definitive valuation.

When a personal loan is cheaper than manufacturer finance

A personal loan finances the full purchase price (minus deposit) as a standard repayment loan. The car is bought outright with the loan funds and is legally yours from day one. The loan is unsecured, which means the car itself is not at risk if repayments are missed (though credit file damage and legal action for non-payment still apply). Personal loan APRs are typically higher than manufacturer PCP or HP rates, particularly for buyers with good credit who qualify for promotional dealer rates at 0% or low single-digit APRs.

Despite the higher APR, a personal loan can still produce lower total interest than a PCP deal at a lower rate. This happens because the personal loan pays down the full balance month by month, reducing the principal on which interest accrues, while PCP keeps the balloon on the balance for the entire term. The tool makes this comparison directly: adjusting the two APR sliders shows where the crossover is for a specific vehicle price and term. A personal loan also avoids the mileage restrictions and condition requirements that PCP agreements carry, which is relevant if you drive high mileage or want to modify the vehicle. The true daily cost of borrowing calculator can break down the loan interest into a daily figure if you want a more granular view of the cost.

The equity question: what you own at the end

The finance structure determines not just what you pay each month but what you own at the end of the agreement, and that has knock-on effects for the cost of the next car. With HP and a personal loan, you own the car after the payments are complete (or from day one for a loan). The car has a market value that can be realised by selling it or trading it in, and that value can fund part of the next purchase. With PCP, you own nothing at the end unless you pay the balloon. If you return the car and take a new PCP deal, you start the next agreement from scratch with a new deposit, a new set of monthly payments, and no equity carried forward (unless the car was worth more than the balloon).

Over multiple vehicle changes, this difference compounds. A buyer who uses HP or a personal loan for each car builds equity that reduces the cost of each subsequent purchase. A buyer who uses PCP and returns the car each time pays for the use of each vehicle but never builds any ownership value. Neither approach is inherently better: PCP suits people who want a new car every few years and prioritise a low monthly payment over ownership, while HP and personal loans suit people who want to own the car and benefit from its residual value when they sell or trade up. The equity panel in the tool explains this distinction plainly for each option.

Frequently asked questions

What is the balloon payment and why does PCP have one?

The balloon payment (also called the Guaranteed Minimum Future Value or GMFV) is the amount set by the finance provider that represents the projected value of the car at the end of the PCP agreement. It is the portion of the vehicle price that is not covered by your monthly payments. The balloon is deferred to the end of the agreement, which is what makes PCP monthly payments lower than HP or a personal loan: you are financing only the depreciation portion (the difference between the vehicle price, minus your deposit, and the balloon) through your monthly payments, rather than the full amount.

At the end of the agreement, you choose whether to pay the balloon and keep the car, return the car and walk away, or use any equity (the difference between the market value and the balloon) as a deposit on a new agreement. The balloon is “guaranteed” in the sense that the finance provider will accept the car back at that value regardless of its actual market price, provided the car meets the agreed mileage and condition terms. If the car is worth more than the balloon, you benefit from the equity. If it is worth less, the finance provider absorbs the shortfall when you return it. This guarantee is the core risk-transfer mechanism in PCP: the finance provider takes the residual value risk, and the buyer gets certainty about the worst-case end-of-agreement position.

Why is the PCP monthly payment lower but the total cost often higher?

PCP monthly payments are lower because they cover only the depreciation portion of the vehicle, not the full purchase price. However, interest on a PCP deal is calculated on the entire credit amount, which includes the deferred balloon. The balloon sits on the balance for the full term, generating interest each month even though no principal repayment is being made against it. This means the total interest on a PCP deal is higher than on an HP deal at the same APR, because HP pays down the entire balance progressively and the interest reduces as the principal falls.

If the car is returned at the end of PCP, the total cost is the deposit plus all monthly payments, which is typically less than the HP or personal loan total because you are not paying for the full car. If the car is kept by paying the balloon, the total cost is the deposit plus monthly payments plus the balloon, which is almost always higher than HP at the same APR. The tool shows both PCP scenarios (returned and kept) alongside HP and personal loan so the cost of each outcome is visible. The relevant comparison depends on what you plan to do at the end: if you always intend to keep the car, HP or a personal loan is typically cheaper. If you always intend to return it, PCP may represent a lower total cost of use.

Can I use a personal loan to buy any car?

Yes. A personal loan is unsecured borrowing that can be used for any purpose, including buying a car from a dealer, a private seller, or at auction. There are no mileage restrictions, condition requirements, or end-of-agreement obligations. The car is yours outright from the point of purchase because it is bought with cash (from the loan), not financed through a credit agreement secured against the vehicle. This is the key practical advantage of a personal loan over PCP or HP: complete flexibility in how the car is used, modified, and disposed of.

The trade-off is that personal loan APRs are typically higher than manufacturer finance rates, particularly for buyers with excellent credit who qualify for promotional dealer offers. For buyers with less strong credit profiles, the difference in APR may be smaller or may even favour the personal loan, since dealer finance providers apply their own credit assessments that may result in higher rates for applicants with adverse credit history. The tool allows you to set different APRs for the two finance types, so testing the comparison at different rate levels shows where the crossover sits for your circumstances. The car financing with bad credit guide covers the options in more detail for borrowers with a limited or adverse credit history.

What happens if I exceed the mileage limit on a PCP agreement?

PCP agreements include an annual mileage allowance, typically set at the start of the agreement at a level such as 8,000, 10,000, or 12,000 miles per year. If the car is returned at the end of the agreement and the total mileage exceeds the agreed allowance, an excess mileage charge is applied for every mile above the limit. The charge varies by provider and vehicle but is commonly between 3p and 12p per mile. On a 3-year agreement with a 10,000 mile allowance, exceeding by 5,000 miles per year would incur a charge on 15,000 excess miles, which could cost between £450 and £1,800.

The excess mileage charge only applies if the car is returned. If the balloon is paid and the car is kept, the mileage is irrelevant to the finance agreement (though it affects the car’s market value). For drivers who consistently exceed 12,000 miles per year, PCP may not be the most cost-effective structure because the excess charges can erode or eliminate the monthly payment advantage. HP and personal loans carry no mileage restrictions, so the total cost is fixed regardless of how many miles the car covers. This is a practical consideration that the tool does not model directly but is worth factoring into the decision alongside the financial comparison.

Which option is best if I have bad credit?

The rates available for all three finance types depend on credit profile, and the relative comparison can change depending on the rates offered to a specific individual. Manufacturer PCP and HP deals at headline promotional rates are typically only available to applicants with good or excellent credit. For applicants with adverse credit history, the dealer finance rate may be significantly higher than the promotional figure, and in some cases a personal loan from a specialist lender may offer a more competitive rate than the dealer’s subprime finance provider. The tool allows you to set different rates for each type, so entering the actual rates offered to you rather than representative figures gives a meaningful comparison.

For borrowers with a limited or adverse credit history, a bad credit loan used to purchase a car outright may offer a simpler structure than PCP or HP, particularly if the finance provider’s credit assessment results in a high APR on the dealer deal. The car is owned outright from day one, there are no end-of-agreement complications, and the loan can be repaid early if circumstances improve. The true daily cost of borrowing calculator is useful for comparing two specific loan offers at different APRs to see what the total cost difference actually amounts to in daily terms.

This tool is for illustrative purposes only and does not constitute financial advice. All calculations use the APR rates and balloon percentage entered and assume standard amortisation with interest on the full credit balance. Actual PCP, HP, and personal loan quotes will vary by lender, vehicle, credit profile, and specific deal terms. PCP balloon/GMFV figures are set by the finance provider and may differ from the percentage used in this tool. Depreciation uses a simplified 15% annual rate for illustration only: actual vehicle depreciation varies by make, model, mileage, condition, and market conditions. Manufacturer finance rates shown in advertising are typically available only to applicants meeting specific credit criteria. PCP mileage charges are illustrative and vary by provider. This tool does not constitute a recommendation of any specific finance product or provider. Actual outcomes will depend on your individual circumstances.
