Total cost of the loan (principal + interest)
Amortization schedule chart

The calculator uses South Carolina's current interest rate assumptions and standard loan terms. You can adjust the loan amount, interest rate, and term length to match your specific situation.

Formula Used

The auto loan calculator uses the standard loan payment formula:

Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

P = Principal loan amount
r = Monthly interest rate (annual rate ÷ 12)
n = Number of payments (loan term in years × 12)

This formula calculates the fixed monthly payment for an auto loan with a fixed interest rate. The calculator then uses this monthly payment to determine the total interest paid and total cost of the loan.

Worked Example

Let's calculate a $25,000 auto loan with a 4.5% annual interest rate over 5 years (60 months):

Convert annual rate to monthly: 4.5% ÷ 12 = 0.375% or 0.00375
Apply the formula:
Monthly Payment = $25,000 × (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1)
Calculate the result: $25,000 × (0.00375 × 1.00375^60) / (1.00375^60 - 1) ≈ $454.23
Total interest paid: $454.23 × 60 - $25,000 ≈ $1,725.80
Total cost of loan: $25,000 + $1,725.80 = $26,725.80

This example shows that a $25,000 loan at 4.5% over 5 years would cost $26,725.80 with $1,725.80 in interest.
