Formula Explained
The weekly auto loan calculator uses the standard loan payment formula to determine your weekly payment amount. The formula accounts for the loan amount, interest rate, and loan term to provide an accurate calculation.
Loan Payment Formula
The formula for calculating the monthly payment is:
M = P [ i(1 + i)n ] / [ (1 + i)n - 1 ]
Where:
- M = Monthly payment amount
- P = Principal loan amount
- i = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (loan term in years multiplied by 12)
For weekly payments, we adjust the formula to calculate payments every week instead of monthly.
The calculator then converts the monthly payment to a weekly payment by dividing by 4 (assuming 4 weeks in a month). This provides a more accurate representation of your weekly financial commitment.
Worked Example
Let's walk through an example to see how the weekly auto loan calculator works. Suppose you're borrowing $20,000 at an annual interest rate of 5% over a 5-year term.
- Enter the loan amount: $20,000
- Enter the annual interest rate: 5%
- Enter the loan term: 5 years
- Click Calculate
The calculator will display your weekly payment, total interest paid, and the total amount repaid over the life of the loan. For this example, your weekly payment would be approximately $125.50, total interest paid would be $3,000, and the total amount repaid would be $23,000.
Key Takeaways
- Your weekly payment is based on the loan amount, interest rate, and loan term.
- The total interest paid is the difference between the total amount repaid and the original loan amount.
- The total amount repaid includes both the principal and the interest.
