Formula Used
The calculator uses the standard auto loan payment formula:
Monthly Payment Formula
M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ]
Where:
- M = monthly payment
- P = principal loan amount (vehicle price - down payment)
- i = monthly interest rate (APR/12/100)
- n = number of payments (loan term in months)
The calculator then adds Texas state taxes and fees to the principal amount before calculating the monthly payment.
Worked Example
Let's calculate a loan for a $25,000 vehicle with a 60-month term, 5% APR, and $2,500 down payment in Harris County, Texas.
| Description | Amount |
|---|---|
| Vehicle Price | $25,000 |
| Down Payment | $2,500 |
| Principal Loan Amount | $22,500 |
| Texas Sales Tax (2%) | $500 |
| Harris County Tax (0.5%) | $112.50 |
| Total Taxes and Fees | $612.50 |
| Total Loan Amount | $23,112.50 |
Using the monthly payment formula with these values, the estimated monthly payment would be approximately $422.50.
