Formula Used

The calculator uses the following formulas to determine your loan terms:

Trade-in Value Calculation

Trade-in Value = (Current Market Value × Condition Factor) - (Mileage Factor × 0.01 × Current Market Value)

Where:

Condition Factor: Excellent = 0.9, Good = 0.8, Fair = 0.7, Poor = 0.6
Mileage Factor: (Miles - 30,000) / 10,000 (capped at 0.5)

Loan Payment Calculation

Monthly Payment = P × (r(1+r)^n) / ((1+r)^n - 1)

Where:

P = Principal (Loan Amount - Trade-in Value)
r = Monthly Interest Rate (Annual Rate / 12)
n = Number of Payments (Loan Term × 12)

Note: These calculations provide estimates only. Actual loan terms may vary based on your credit score, lender requirements, and other factors.

Worked Example

Let's calculate a loan for a $25,000 vehicle with these details:

Current Market Value: $20,000
Condition: Good
Miles: 45,000
Year: 2018
Loan Amount: $22,000
Loan Term: 5 years
Interest Rate: 4.5%

Step 1: Calculate Trade-in Value

Condition Factor = 0.8 (Good)

Mileage Factor = (45,000 - 30,000) / 10,000 = 1.5 (capped at 0.5)

Trade-in Value = ($20,000 × 0.8) - (0.5 × 0.01 × $20,000) = $16,000 - $100 = $15,900

Step 2: Calculate Loan Terms

Principal = $22,000 - $15,900 = $6,100

Monthly Interest Rate = 4.5% / 12 = 0.375%

Number of Payments = 5 × 12 = 60

Monthly Payment = $6,100 × (0.00375(1+0.00375)^60) / ((1+0.00375)^60 - 1) ≈ $112.50

Results

Estimated Trade-in Value: $15,900
Monthly Payment: $112.50
Total Interest Paid: $1,100
Total Cost of Loan: $7,200

Interpreting Results

The calculator provides several key metrics to help you evaluate your auto loan:

Trade-in Value

This is your estimated value based on the inputs you provided. Dealers may offer different amounts, so this is just an estimate.

Monthly Payment

This shows how much you'll pay each month. Compare this with your budget to ensure it's affordable.

Total Interest Paid

This represents the cost of borrowing over the life of the loan. Lower interest rates save you money.

Total Cost of Loan

This combines your principal and interest payments. It helps you understand the true cost of financing your vehicle.

Tip: Consider getting pre-approved for a loan before visiting dealerships. This gives you a clear budget and can help you negotiate better terms.
