Example: Estimating a Car Loan with the Calculator

Let’s say you’re considering buying a car with the following details:

• Vehicle Price: $30,000
• Down Payment: $5,000
• Trade-in Value: $3,000
• Sales Tax Rate: 7%
• Interest Rate: 6%
• Loan Term: 60 months (5 years)
• Other Fees: $800

Here’s how the calculator would break it down:

• Vehicle Price: $30,000
• Subtract Down Payment + Trade-in = $22,000
• Sales Tax (7% of $22,000) = $1,540
• Loan Amount (with fees) = $23,540 + $800 = $24,340
• Monthly Payment ≈ $471
• Total Cost (over 60 months) ≈ $28,260

This example shows how quickly the tool simplifies a complex calculation, giving you a realistic expectation before stepping into a dealership.
