What is the maximum finance charge that can be applied to a consumer loan under Reg Z?

Under Regulation Z, there is no specified maximum finance charge that can be applied to a consumer loan. This regulation does establish requirements for disclosure and the calculation of finance charges to ensure transparency and protect consumers, but it does not impose a ceiling on the finance charges lenders can impose.

This principle recognizes that financial institutions have the discretion to set their own rates based on market conditions, the type of loan, and the creditworthiness of the borrower. Therefore, the appropriate answer is that there is no maximum finance charge applicable under Regulation Z.

The other choices suggest fixed percentages, which do not reflect the flexible nature of finance charges as dictated by Regulation Z, nor do they account for the variety of loans available in the marketplace. Different types of loans can have varying finance charge structures based on legitimate borrower risk assessments.
