Depreciation is often the largest ownership cost and the easiest to ignore at the dealership. Putting a number on it changes how you negotiate.

Adjust the residual percentage when you have marketplace evidence; otherwise use the defaults as a conservative planning scaffold.

resale = price × residual%; depreciation = price − resale.

What residual should I assume at 5 years?

A rough planning band for mass-market cars is often near half the original price, but bestsellers can do better and niche cars worse.

Does kilometres matter?

Yes. Very high odometer readings usually weaken bids — lower the residual % if the car will be high-km.
