Calculation Results
Out-The-Door (OTD) Vehicle Purchase Formula
OTD Price = (Vehicle Price − Rebates) + Itemized Fees + Sales Tax − Net Trade-In Equity- Net Trade Equity = Trade-In Valuation minus Existing Loan Payoff Balance (negative equity adds to the loan).
- Total Amount Financed = Out-The-Door Price minus Cash Down Payment.
- Cash Due at Signing = Down Payment Cash.
Step-by-Step Worked Example
Scenario: Buying a $32,000 vehicle with a $1,000 rebate, $2,000 trade equity, and $4,000 cash down
Calculation Steps:
- Taxable Amount = ($31,000 − $8,000) + $495 = $23,495.00
- Sales Tax = $23,495 × 0.065 = $1,527.18
- Gross Delivered Price = $31,000 + $495 + $350 + $1,527.18 = $33,372.18
- Out-the-Door Price (after $2,000 trade equity) = $31,372.18
- Amount Financed (after $4,000 down cash) = $27,372.18
Result: The Out-The-Door price is $31,372.18. With $4,000 cash down, you finance $27,372.18.
