Formula Used

The calculator uses the following formulas to determine your auto loan payments:

Loan Amount = Vehicle Price - Down Payment Monthly Interest Rate = (Interest Rate / 100) / 12 Number of Payments = Loan Term × 12 Monthly Payment = (Loan Amount × Monthly Interest Rate × (1 + Monthly Interest Rate)^Number of Payments) / ((1 + Monthly Interest Rate)^Number of Payments - 1) Total Interest = (Monthly Payment × Number of Payments) - Loan Amount Sales Tax Amount = (Vehicle Price × Sales Tax) / 100 Total Cost = (Vehicle Price + Sales Tax Amount + Registration Fee) + (Monthly Payment × Number of Payments)

These formulas help calculate your monthly payment, total interest, and the complete cost of your auto loan including taxes and registration fees.

Worked Example

Let's walk through an example to illustrate how the calculator works.

Example Calculation

Vehicle Price: $25,000

Down Payment: $3,000

Loan Term: 5 years

Interest Rate: 4.5%

Sales Tax: 8%

Registration Fee: $200

Calculations:

Loan Amount = $25,000 - $3,000 = $22,000
Monthly Interest Rate = (4.5 / 100) / 12 ≈ 0.00375
Number of Payments = 5 × 12 = 60
Monthly Payment ≈ $412.38
Total Interest ≈ $1,906.64
Sales Tax Amount = ($25,000 × 8) / 100 = $2,000
Total Cost ≈ $25,000 + $2,000 + $200 + ($412.38 × 60) ≈ $28,306.64

In this example, your estimated monthly payment is $412.38, and the total cost of the vehicle including taxes and fees is approximately $28,306.64.
