Trade-in overtrade calculator
A big trade-in offer can hide a small discount. See your real net cost to change cars, the one number to compare across dealers, and how much of that generous trade-in is really just a discount in disguise.

After trading at true value
A high trade-in offer can be perfectly fine. What matters is the net cost to change cars: compare that number across dealers, not who quotes the biggest trade-in. The same car can have a huge trade-in and a worse total deal.
How the trade-in trick works
A dealer can offer a high trade-in for your old car while giving little or no discount on the new one. The generous trade-in feels great, but the total cost can be worse.
The number that matters is the net cost to change = new car price minus discount minus trade-in, plus any loan you still owe on the old car. Compare that across dealers, not the trade-in.
If you know your car's market value, an "overtrade", a trade-in above that value, is really just an extra discount routed through your old car. A high trade-in is fine when the net cost wins.
Enter the new car's all-in price including COE, plus any mandatory packages and admin fees. Exclude optional add-ons, and do not double-count rebates already shown in the quote. This is the cost to change cars before financing the new one (use our loan calculator for that). Your car's market value is an estimate (use our valuation tool).
