Car Finance — No Deposit
Zero deposit car finance exists. Most lenders offer it. But it costs more than you think — and not just in interest.
No deposit = more borrowed = more interest = more risk.
On a £15,000 car at 6.9% APR over 48 months, a 10% deposit (£1,500) saves you ~£450 in interest and keeps you out of negative equity from month 1. Zero deposit means you owe more than the car is worth for the first 12–18 months.
The real cost of zero deposit
20% deposit (£3,000)
£286/month
£15,000 car, 6.9% APR, 48 months
Total interest: £1,728
10% deposit (£1,500)
£322/month
£15,000 car, 6.9% APR, 48 months
Total interest: £1,944
No deposit (£0)
£358/month
£15,000 car, 6.9% APR, 48 months
Total interest: £2,160
The difference between 20% deposit and zero deposit on this example is £432 in extra interest and £72/month higher payments. That's real money — and it doesn't include the higher APR that some lenders charge for zero-deposit deals.
The negative equity problem
A new car typically loses 15–20% of its value in the first year and 40–50% over three years. If you put down no deposit, you're in negative equity from day one — you owe more than the car is worth.
Negative equity matters because:
- You can't sell the car without covering the shortfall from your own money.
- If the car is written off (accident, theft), your insurance pays market value — which is less than you owe. You need GAP insurance to cover the difference.
- Trading in early means rolling the negative equity into your next deal. This is how people end up owing £18,000 on a car worth £12,000.
When no deposit is acceptable
- Manufacturer 0% PCP offers. If the manufacturer is subsidising the interest to 0% AND offering zero deposit, the cost penalty disappears. You're not paying interest anyway. But check the balloon payment is reasonable.
- You have savings but prefer liquidity. If you could put down a deposit but prefer to keep cash available, and the APR difference is negligible, this is a rational choice. Just understand the negative equity risk.
- Short-term PCP with strong residuals. On a car that holds value well (Toyota, Porsche), a 24-month PCP with no deposit may never dip into serious negative equity.
When no deposit is a warning sign
- You genuinely can't save a deposit. If you can't save £1,500, can you really afford £358/month for 4 years plus insurance, fuel, and maintenance? This isn't judgement — it's maths.
- The dealer is pushing zero deposit. "No deposit needed!" is a sales tactic designed to get you focused on the monthly payment rather than the total cost.
- It's paired with a long term. Zero deposit + 60-month term = maximum interest and maximum time in negative equity. This is the most expensive way to finance a car.
How to reduce your deposit requirement
- Part-exchange. Your current car's value acts as a deposit. Even £2,000 from an older car significantly improves the deal.
- Manufacturer contribution. Many PCP deals include a "manufacturer deposit contribution" of £500–£3,000. This effectively reduces your deposit without you spending cash — but the manufacturer adjusts the car price to cover it.
- Save for 3–6 months. Setting aside £250/month for 6 months gives you £1,500 deposit. That saves £450+ in interest and gives you better APR options.
