Car Loan Calculator Description

Understanding Car Loans

A car loan enables you to finance a vehicle purchase by borrowing money and repaying it over time with interest. This calculator helps you:

  • Estimate your monthly payment
  • View a full amortization schedule
  • Analyze how interest and loan terms affect your total cost
  • Simulate extra payments and their benefits

Calculation Methodology

We use the standard fixed-rate loan formula:

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

Where:

  • P: Loan amount after down payment
  • r: Monthly interest rate = APR ÷ 12 ÷ 100
  • n: Number of monthly payments = Loan Term × 12

Each payment consists of a principal and interest portion. Over time, the interest portion decreases while the principal share grows.

Edge Case Handling

  • 0% Interest: Monthly payment = Principal ÷ Term
  • Down Payment ≥ Price: No loan is needed; output will be $0 payments
  • Short-Term Loans: Higher monthly payments, lower interest
  • Extra Payments: Accelerate payoff and reduce interest
  • Balloon Payments: Simulate by adjusting loan term and making a final manual lump-sum entry

Real-World Case Studies

Case Study 1: Low-Interest Long-Term Loan

  • Car Price: $30,000
  • Down Payment: $5,000
  • APR: 2.5%
  • Term: 72 months
  • Extra Payment: $50/month → saves $600+ interest and shortens loan by 7 months

Case Study 2: High-Interest Short-Term Strategy

  • Car Price: $15,000
  • Down Payment: $3,000
  • APR: 9%
  • Term: 24 months
  • Result: High monthly payments (~$545), but only ~$800 total interest

Any extra payment goes toward reducing the principal, shortening the loan term and reducing total interest paid.

While not built-in, you can simulate it by shortening the loan term and adjusting a manual final payoff at the end.
