Every car lease deal on every website has those funny numbers stamped on it. 9+23. 6+35. 3+47. They look like a riddle. They aren't — they're actually the most important number on the page after the monthly price. Here's the plain-English version.

What "9+23" actually means

It's just an abbreviation for the structure of the lease:

  • First number = the initial payment, expressed as a multiple of the monthly payment
  • Second number = the number of monthly payments that follow

So 9 + 23 means 9 months upfront, then 23 monthly payments after that. Add those together and you get the total term: 9 + 23 = 32 payments, but the term is described as 24 months (because the 9 months upfront cover 9 of the 24 months, and the 23 monthlies cover months 2 through 24 — you can see why the codes are shorter).

📋 The cheat sheet

1+23 = 24-month term, 1 month upfront, 23 monthlies. Lowest cash up front, highest monthly.

9+23 = 24-month term, 9 months upfront, 23 monthlies. Lots of cash up front, lower monthly.

12+23 = 24-month term, 12 months upfront, 23 monthlies. Even more cash up front, even lower monthly.

Why this number matters more than people realise

The headline monthly price changes dramatically based on the profile. Same car, same term — different profile, different monthly.

Take a Peugeot e-408 Allure on a 36-month / 5,000 mile lease. The total cost of leasing it is fixed (call it £9,886). What changes is how that total is split between your initial payment and your 35 monthly payments:

ProfileInitialMonthlyYou pay total
1 + 35£275£275/mo£9,887
3 + 35£780£260/mo£9,887
6 + 35£1,447£241/mo£9,887
9 + 35£2,022£225/mo£9,887
12 + 35£2,524£210/mo£9,887

Notice what happens: putting 12 months down drops the monthly by £65 vs putting just 1 month down. Total cost is the same — but the cashflow shape is completely different.

Which profile is right for you?

Pick a lower initial (1 or 3 months upfront) if:

  • You'd rather keep cash in your pocket and pay a higher monthly
  • You're moving job or are between bonuses
  • You want to use the cash for something else (deposit on a house, etc.)

Pick a higher initial (9 or 12 months upfront) if:

  • You've got cash sitting in a current account and want the lowest possible monthly
  • Cashflow management matters more than total liquidity
  • You want a "show-off" headline figure — most car ads quote the lowest monthly possible, which comes from the highest initial

💡 A common mistake: paying more upfront doesn't save you money overall in a lease (unlike a mortgage or a loan). The total cost is the same. You're just reshuffling when you pay.

Three myths about initial payments

1. "Bigger initial = better deal." Not true. The total cost is fixed. A bigger initial just lowers the monthly headline — it's identical money overall.

2. "It's a deposit I'll get back." No. The initial payment is exactly that — a payment, not a refundable deposit. Once paid, it's gone.

3. "Lower initial means cheaper credit." Also no. Lease finance is structured as fixed monthly rentals; the profile just changes the schedule, not the interest.
