What This Calculator Does

Unlike most tools, this isn’t about estimating monthly costs – you already know those. Instead, we help you add it all up:

• 🚗 Upfront Payment (initial rental or deposit)

• 🧾 Broker Fee (if applicable)

• 📅 Monthly Payment x Lease Term

And boom – we show you the total cost of your lease, so you know exactly what you’re paying over the full term.

We also show you the Effective Monthly Cost. This gives you a more accurate idea of what the lease is really costing you each month when you factor in all costs — including initial payment, monthly rentals, and any fees. We calculate it by adding up the total cost over the lease term and dividing it by the number of months.

For example:
If you're leasing a car for 3 years (36 months) and the total cost across the lease — including the upfront payment — comes to £10,800, the Effective Monthly Cost would be £300 (£10,800 ÷ 36).

Why It Matters

Most lease deals are advertised by monthly cost – but that’s only part of the story. With our calculator, you can:

• ✅ Compare lease deals properly, side by side

• ✅ Avoid nasty surprises or hidden costs

• ✅ Make smarter, more confident financial decisions

Don’t Forget GAP Insurance

If your lease car is written off or stolen, your insurer might only pay what the car is worth at the time – not what you owe or paid. That’s where GAP insurance comes in.

We recommend checking out ALA Insurance, a trusted UK provider of GAP insurance that can cover the difference between your insurance payout and what your lease actually costs. It’s peace of mind for just a few pounds a month.
