Frequently asked questions

How is the monthly payment calculated?

With the standard amortization formula: payment = P x r(1+r)^n / ((1+r)^n - 1), where r is the monthly rate and n is the number of payments. Total interest is payment times n minus the loan amount.

Why does the lower rate not always win?

Term length matters as much as rate. A longer term at a lower rate can still cost more total interest than a shorter term at a slightly higher rate. That is exactly what this comparison reveals.

Does this include fees or taxes?

No. This compares the pure loan math only. Origination fees, insurance, taxes and prepayment penalties can change the real winner, so always read the lender's full terms.
