A deposit is the upfront payment you make before your car finance begins. It reduces the amount you borrow, which means lower monthly payments and less interest over the life of the deal. Most lenders suggest around 10% of the car's price, but you do not always need one at all.
The real question is not "how much do I need?" but "how much difference does it actually make?" This guide shows you exactly what different deposit amounts cost and save on the same car, so you can decide what makes sense for your budget.

There is no fixed rule. Most lenders use 10% of the car's price as a starting point. On a £15,000 car, that is £1,500. On a £10,000 car, it is £1,000.
But the range is wide. Some lenders accept nothing at all. Others may ask for 15 to 20%, especially if your credit is not strong. Here is a rough guide to what different lenders typically expect.
| Your Credit | Typical Deposit Expected | Why |
|---|---|---|
| Excellent | 0% to 10% | Low risk to the lender. You may qualify for zero-deposit deals. |
| Good | 10% | The standard benchmark. Keeps monthly payments and interest reasonable. |
| Fair | 10% to 15% | A bigger deposit reduces the lender's risk and may improve your chances of approval. |
| Poor | 15% to 20%+ | Specialist lenders may require more upfront. A trade-in can count towards this. |
A deposit is not the only upfront cost. You will also need to budget for car insurance, road tax, and potentially an MOT if you are buying used. Make sure you are not draining every penny just to hit a deposit target.
This is where it gets real. Here is the same £15,000 car financed on HP over 4 years at 9.9% APR, with four different deposit amounts. These are illustrative figures. The actual rate you are offered will depend on your personal circumstances.
| Deposit | Amount Borrowed | Monthly Payment | Total Interest | Total You Pay |
|---|---|---|---|---|
| £0 (0%) | £15,000 | £377 | £2,096 | £18,096 |
| £750 (5%) | £14,250 | £358 | £1,990 | £17,740 |
| £1,500 (10%) | £13,500 | £339 | £1,772 | £17,272 |
| £3,000 (20%) | £12,000 | £302 | £1,496 | £16,496 |
The difference between putting nothing down and putting 20% down is £600 in interest and £75 less each month. Over the full term, £0 deposit costs you £1,600 more than £3,000 deposit. That is real money, and it is the same car.
But notice the jump between 0% and 10% is only £324 in interest. If you can stretch to 10%, you get most of the benefit without tying up a huge amount of cash. That is why 10% is the sweet spot for most people.
A bigger deposit always saves you money on interest. But do not empty your savings to hit a target. You still need a buffer for insurance, road tax, fuel, and the unexpected. The best deposit is the biggest one you can comfortably afford without leaving yourself short.
Many lenders offer no deposit car finance on both HP and PCP deals. You borrow the full price of the car and start making payments straight away. No cash needed upfront.
Zero deposit works well if you need a car now and do not have savings to put down, or if you would rather keep your cash available for other things. But there are trade-offs to be aware of.
Higher monthly payments. You are borrowing more, so each month costs more.
More interest overall. Interest is charged on the full amount, so you pay more over the life of the deal.
Higher risk of negative equity. If the car loses value faster than you pay it down, you could owe more than the car is worth. This matters most in the first year or two, especially with PCP.
Approval may be harder. Some lenders see zero-deposit applications as higher risk. If your credit is not strong, putting even a small amount down can improve your chances.
Zero deposit is not a bad option. It is just a more expensive one. If you can put down even £500, it reduces the amount you borrow and lowers your monthly payments. Every pound of deposit saves you more than a pound in total because you avoid paying interest on it.
Yes. If you already have a car, its value can count as your deposit. This is one of the easiest ways to put a meaningful amount down without needing cash in hand.
Here is how it works. The dealer values your old car. If it is worth £2,000, that £2,000 comes off the amount you need to borrow on the new car. The effect on your monthly payments is exactly the same as putting £2,000 in cash down.
If your old car still has finance on it, the dealer can usually settle that as part of the deal. If the car is worth more than the outstanding finance, the difference (your positive equity) becomes your deposit. If it is worth less, you are in negative equity and would need to cover the shortfall or add it to the new deal. Our guide to selling a car on finance explains how this works in detail.
Before you agree a part-exchange value, it is worth getting an independent valuation. You can get competing offers via Brumble to see what your car is actually worth on the open market. Dealers sometimes offer less on a part-exchange than you could get selling separately.
Your deposit must come from your own funds or a part-exchange. A deposit funded by a credit card or personal loan is not treated as a genuine deposit by most lenders, and borrowing to deposit actually worsens your affordability position because it adds another monthly commitment.
If your credit score is lower, a bigger deposit can make a real difference to your chances of being approved. It reduces the amount the lender needs to risk, which makes them more willing to say yes.
Specialist bad credit car finance lenders may ask for 15 to 20% deposit, though some will accept less. Even if a lender will approve you with no deposit, putting something down could get you a lower APR, which means less interest paid overall.
If you are struggling to save a deposit, a part-exchange is your best route. Even a car worth £500 brings your borrowing down and shows the lender you have something at stake.

It matters on both, but it plays out slightly differently.
With HP, your deposit directly reduces the total amount you borrow and pay back. Every pound you put down is a pound less to repay, plus the interest you save on it. It is straightforward maths.
With PCP, your deposit reduces the amount financed, but the balloon payment at the end stays the same. So your monthly payments drop, but the final lump sum (if you want to keep the car) does not change. A bigger deposit on PCP also reduces the risk of ending up in negative equity during the agreement.
On PCP, there is another angle worth knowing. Some manufacturers offer "deposit contribution" promotions on new cars, where they add their own money to your deposit. This can be a genuinely good deal, but check the overall price of the car, because the contribution is sometimes offset by a higher list price or less room for negotiation elsewhere.
If you are weighing up PCP against HP, our PCP vs HP comparison guide has full worked examples showing how each one works at different price points.
Set a target and a date Work out how much car you want and what 10% of that looks like. Give yourself a realistic deadline. Even 3 months of focused saving can make a difference.
Sell what you do not need Old phones, clothes, electronics, furniture. Small amounts add up faster than you think. If you have a car to trade in, that is your biggest single lever.
Set up a separate savings pot Move a fixed amount on payday into a pot you do not touch. Automating it means you do not have to think about it or be tempted to spend it.
Check your eligibility now anyway You do not have to wait until you have saved. A soft search eligibility check shows you what rate and amount you could be offered today. That helps you work out the right deposit target for the car you actually want.
Yes. Many lenders offer zero-deposit car finance on both HP and PCP deals, subject to status. You will borrow the full price of the car, which means higher monthly payments and more interest paid overall, but it is a genuine option if you need a car and do not have savings to put down.
It is possible but harder. Most specialist bad credit lenders prefer to see some deposit because it reduces their risk. If you have a car to trade in, using it as a part-exchange deposit can help. Even a small amount down improves your chances of being approved and may get you a lower APR.
There is no universal minimum. Some lenders accept £0, while others may require 10% or more depending on your credit profile and the car. If your credit is poor, some specialist lenders set a minimum (for example, £400 to £500). The best way to find out is to run a soft search eligibility check, which shows you what different lenders would require from you personally.
A bigger deposit reduces your monthly payments and the total interest you pay. On PCP specifically, it also reduces the gap between what you owe and what the car is worth, making negative equity less likely. But there is a balance. Putting a very large deposit on a PCP means tying up cash in a car you might hand back at the end. If you plan to keep the car, a bigger deposit makes more sense. If you are likely to hand it back, a moderate deposit may be a better use of your money.
Yes. The value of your current car can be used as a deposit on most HP and PCP agreements. If the car has outstanding finance, the dealer can usually settle it as part of the deal. Any positive equity (the difference between the car's value and what you owe) becomes your deposit. If you want to check what your car is worth before visiting a dealer, you can get competing offers via Brumble.
Not always directly, but it can help. A bigger deposit means borrowing less, which some lenders reward with a slightly better APR because their risk is lower. Even if the APR stays the same, you still save money because interest is calculated on the amount borrowed, which is smaller. So a bigger deposit saves you money either way. Our guide to car finance APR rates explains what rates to expect at different credit levels.
It depends on how urgently you need a car. If you can wait a few months and save even 5 to 10%, you will pay less interest and have lower monthly payments. If you need a car now for work or daily life, zero-deposit finance is a practical option. Just make sure the monthly payments fit comfortably within your budget.
A deposit contribution is money the car manufacturer or dealer adds to your deposit on top of what you put in yourself. It is most common on new car PCP deals as a sales promotion. For example, a manufacturer might add £1,000 to your deposit to bring the monthly payments down. It is worth checking whether the overall deal is still competitive, as the car's list price may already account for the contribution.
Some dealers accept credit card payments for part of the deposit, but most finance lenders expect the deposit to come from your own funds or a part-exchange. Using a credit card to fund a deposit adds another monthly commitment on top of your car finance, which worsens your affordability and could affect your chances of being approved. It is generally better to save the deposit from your own money.
No. Your deposit reduces the amount you borrow at the start of the agreement. It is not refundable if you hand the car back at the end of a PCP deal. However, if the car is worth more than the balloon payment when you return it, that positive equity can be used as a deposit on your next car, which has a similar effect.
