How to Use the Car Buy Calculator

Our Car Buy Calculator is user-friendly and requires only four key inputs:

  2. Down Payment – Input the upfront amount you plan to pay. This reduces your loan principal and monthly payments.
  3. Loan Term (Years) – Specify the duration of your car loan, usually between 1 and 10 years.
  4. Interest Rate (%) – Enter your loan’s annual interest rate.

Once these values are entered:

  2. Click Reset to clear inputs and start a new calculation.

Example Calculation

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

  • Car Price: $25,000
  • Down Payment: $5,000
  • Loan Term: 5 years (60 months)
  • Interest Rate: 6%

Step-by-Step Calculation:

  1. Subtract the down payment from the car price:
    $25,000 − $5,000 = $20,000 principal.
  2. Convert the annual interest rate to monthly:
    6% ÷ 12 = 0.5% monthly interest.
  3. Calculate the monthly payment using the formula: Monthly Payment=P×r1−(1+r)−n\text{Monthly Payment} = \frac{P \times r}{1 - (1 + r)^{-n}}Monthly Payment=1−(1+r)−nP×r​ Where:
    • P=20,000P = 20,000P=20,000 (principal)
    • r=0.005r = 0.005r=0.005 (monthly interest rate)
    • n=60n = 60n=60 (loan term in months)
    Monthly Payment ≈ $386.66
  4. Total Payment = 386.66 × 60 = $23,199.60
  5. Total Interest = 23,199.60 − 20,000 = $3,199.60

With this calculator, these results appear instantly, saving time and reducing calculation errors.
