Formula Used
Total Cost Formula
The total cost is calculated using this formula:
Total Cost = (Vehicle Price - Trade-In Value) + (Vehicle Price × Sales Tax Rate) + (Vehicle Price × Title/Registration Fee) + (Vehicle Price × Destination Charge) - Down Payment
Where:
- Sales Tax Rate varies by state (typically 5-10%)
- Title/Registration Fee is a fixed fee (typically $50-$200)
- Destination Charge is a fixed fee (typically $500-$1,500)
Worked Example
Let's calculate the total cost for a $30,000 vehicle in California with a $5,000 trade-in and $3,000 down payment.
| Item | Amount |
|---|---|
| Vehicle Price | $30,000 |
| Trade-In Value | -$5,000 |
| Sales Tax (7.25%) | $2,175 |
| Title/Registration Fee | $100 |
| Destination Charge | $1,000 |
| Down Payment | -$3,000 |
| Total Cost | $26,275 |
Your total cost would be $26,275 after accounting for all fees and your trade-in.
