Whether you are buying a new or used car, this tool gives you a complete picture of your total purchase cost.

A Car Purchase Calculator is a tool used to estimate the total cost of buying a vehicle, including upfront and financing expenses.
It helps users:

How the Calculator Works
The calculator first calculates the total purchase price by adding taxes and fees to the vehicle price. Then it subtracts the down payment to determine the loan amount.
After that, it applies loan amortization to calculate monthly payments and total repayment cost.
This gives you a complete breakdown of both upfront and long-term expenses.

Practical Example
Let’s assume:
- Vehicle Price: $30,000
- Sales Tax: $2,000
- Fees: $500
- Down Payment: $5,000
- Interest Rate: 6%
- Loan Term: 60 months
Step 1: Total Purchase Price
$30,000 + $2,000 + $500 = $32,500
Step 2: Loan Amount
$32,500 – $5,000 = $27,500
Step 3: Monthly Payment
