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 / 12)
- n = Number of payments (Loan term in months)
The interest rate is determined based on your estimated credit score using Ally Bank's standard rate table.
Worked Example
Let's calculate a $25,000 loan with a 60-month term and a 720 credit score:
Example Calculation
Loan amount: $25,000
Term: 60 months
Credit score: 720
Estimated interest rate: 4.5% (based on Ally Bank's rate table)
Monthly payment: $448.43
Total interest: $3,490.80
Total cost: $28,490.80
This example shows that a $25,000 loan with a 60-month term and good credit would have a monthly payment of $448.43, with $3,490.80 paid in interest over the life of the loan.
