Formula Used in Car Payment Calculation
The calculator uses the standard auto loan amortization formula, which is widely used by banks and financial institutions.
Monthly Payment Formula:
M=(1+r)n−1Pr(1+r)n
Where:
- M = Monthly payment
- P = Loan amount (car price − down payment + tax)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of monthly payments (years × 12)
Understanding the Calculation Process
To better understand how your monthly payment is calculated, here is a breakdown:
1. Loan Amount
Loan amount is not just the car price. It includes:
- Car price
- Minus down payment
- Plus sales tax
2. Interest Conversion
Annual interest rate is converted into monthly interest because payments are made every month.
3. Loan Duration
Loan term is converted into total months.
4. Amortization
Each monthly payment includes:
- Interest portion
- Principal repayment
At the beginning of the loan, you pay more interest. Over time, principal repayment increases.
Example Calculation (Car Price = $30,000)
Let’s understand how the calculator works with a real example:
Assumptions:
- Car Price: $30,000
- Down Payment: $5,000
- Interest Rate: 6% annually
- Loan Term: 5 years
- Sales Tax: 8%
Step 1: Loan Amount
- $30,000 − $5,000 = $25,000
- Tax (8%) = $2,400
- Total Loan = $27,400
Step 2: Monthly Interest Rate
- 6% ÷ 12 = 0.5% monthly
Step 3: Loan Duration
- 5 years × 12 = 60 months
Step 4: Result
- Monthly Payment ≈ $529
- Total Payment ≈ $31,740
- Total Interest ≈ $4,340
