This tool will help you calculate the total cost of a car loan including interest.
How to Use the Car Loan Interest Rate Calculator
To use this calculator, follow these steps:
- Enter the loan amount in dollars in the “Loan Amount ($)” field.
- Enter the interest rate as a percentage in the “Interest Rate (% per year)” field.
- Enter the loan term in years in the “Loan Term (years)” field.
- Select the compound frequency from the options available (Monthly, Quarterly, Semi-annually, or Annually).
- Click the “Calculate” button.
How it Calculates the Results
This calculator uses the compound interest formula to calculate the total amount you will owe over the life of the loan. The formula used is:
A = P(1 + r/n)^(nt)
- A = the future value of the loan, including interest
- P = the principal loan amount
- r = the annual interest rate (decimal)
- n = the number of times that interest is compounded per year
- t = the number of years the money is borrowed for
The total interest is then calculated by subtracting the principal from the future value.
Limitations
This calculator assumes that the interest rate remains constant over the life of the loan and that payments are made consistently on time according to the compounding period. In real-life scenarios, interest rates might fluctuate, and additional fees might apply, which are not accounted for in this calculator.
