Why depreciation belongs in a real car budget

Depreciation is the difference between what a vehicle was worth and what it is worth later. You do not receive a monthly bill for it, which is why it is easy to ignore, but it can be one of the largest costs of owning a newer vehicle.

If a $35,000 vehicle is worth $19,000 several years later, $16,000 of value has disappeared. Spread over the ownership period, that value loss can be compared with insurance, fuel, maintenance and financing costs.

How DriveMath calculates it

This calculator uses the values you enter rather than pretending every make and model depreciates at the same rate. It measures loss to date from purchase price to current value, then estimates future depreciation from current value to your expected future value.

The result is not a prediction of the used-car market. Mileage, accident history, trim, condition, region, vehicle demand and changes in the broader market can all affect resale value. Use conservative estimates and test more than one future-value scenario.

Example$28,000 current value → $19,000 in three years

That is $9,000 of estimated future depreciation, or about $250 per month before considering financing, insurance, fuel or maintenance.

Questions

Before you use the result

Is depreciation the same as what I still owe?

No. Depreciation is a change in vehicle value. Your loan balance is a separate financing amount. When the loan balance is higher than the vehicle value, you have negative equity.

Why use a future value instead of a fixed percentage?

Different vehicles and market conditions depreciate differently. Using a value you can research makes the estimate more transparent and easier to stress-test.

Should I include sales tax in the purchase price?

For a pure vehicle-value comparison, use the vehicle price itself. Taxes and fees are ownership costs, but they generally are not part of the resale value of the vehicle.
