How to Use This Calculator

- Enter the loan amount you're requesting from Costco.

The calculator uses the standard auto loan formula to provide accurate estimates. Remember that actual loan terms may vary based on your credit score and other factors.
Formula Used
The calculator uses the standard auto loan payment formula:
Monthly Payment Formula
M = P [ i(1 + i)n ] / [ (1 + i)n - 1 ]
Where:
- M = Monthly payment
- P = Principal loan amount
- i = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (loan term in years × 12)
Total interest is calculated by subtracting the principal from the total of all monthly payments.
Worked Example
Let's calculate a $25,000 loan at 6% interest over 5 years:
- Monthly interest rate = 6% ÷ 12 = 0.5% or 0.005
- Number of payments = 5 × 12 = 60
- Monthly payment = $25,000 [ 0.005(1 + 0.005)60 ] / [ (1 + 0.005)60 - 1 ] ≈ $482.65
- Total payments = $482.65 × 60 ≈ $28,959
- Total interest = $28,959 - $25,000 = $3,959
Example Result
For a $25,000 loan at 6% over 5 years, your monthly payment would be approximately $482.65, with a total interest cost of $3,959.
