Tesla Part-Exchange Value Calculator

Get a ballpark for your Tesla three ways — part-exchanging it with Tesla or a dealer, taking an instant offer from an online car-buying service, or selling it privately. Then see what's left after your finance settlement figure, and what waiting another year might cost.

Most states tax only the price minus your trade. A handful limit or don't give the credit — e.g. California, Hawaii, Maryland, Virginia and DC; Michigan caps it. Check your state's current rule.

Mileage is compared with 10,000 miles a year. Selling costs = online listing, valeting and a vehicle history check.

The cost of waiting

ℹ️

These are estimates, not offers. Real prices swing with local supply, new-car price cuts, colour, wheels, service and accident history and the month you sell. Get two or three real quotes — Tesla's part-exchange valuation, an online car-buying service and a local dealer — before you decide.

How this is calculated

  • Base value = original list price × a typical UK retained-value curve for the model at your car's age (counted from mid-year). It reflects average condition at about 10,000 miles a year. Used EV prices in the UK have fallen faster than in the US, and the curve reflects that.
  • Mileage: each mile above or below 10,000 a year moves the value by the rate you set (≈ 8–12p is typical), capped at ±30%.
  • Condition: excellent +5%, good 0%, fair −10%, rough −22%. Local demand: strong +4%, weak −5%. Battery health (optional) is compared with a typical figure for the car's age, ±1.2% of value per point.
  • Channels: private sale ≈ 95–104% of that market value; online car-buying services ≈ 85–93% (often less after inspection); dealer part-exchange ≈ 80–88%. Buyers who resell need a margin, which is why part-exchange comes in lowest.
  • Equity = part-exchange mid estimate − your finance settlement figure. There's no VAT or tax saving from part-exchanging in the UK, so it's a straight comparison of money in your pocket.
Is a private sale always worth it?
It usually brings the most money, but subtract listing and valeting costs and your time — and you'll handle viewings, test drives, payment safety and settling any finance yourself (a car with outstanding finance can't be sold until it's settled). When the gap is a few hundred pounds, part-exchanging is often the better deal.
What if I owe more than it's worth?
That's negative equity. A dealer can add it to your next PCP or HP agreement, but you'll pay interest on it. On PCP or HP you may be able to hand the car back under voluntary termination once you've paid half of the total amount payable. See the car finance tool to model it.
Does FSD add value on a used Tesla?
A little, sometimes. Purchased FSD normally stays with the car, but UK used buyers rarely pay much for it — partly because fewer features are enabled here — and many part-exchange quotes ignore it.
