Marcus Vance
Editor · consumer finance math (United States)
Marcus Vance edits FeeFriction from the United States: calculators and guides that quantify banking fees, APR total cost, credit card interest drag, and investment expense ratios. Content is educational — not personalized financial, tax, or investment advice.
Credentials / sources frame: Independent editorial research using CFPB, Federal Reserve, IRS, and BLS public data. Not a CFA, CFP, CPA, or broker.
Editorial review focuses on transparent assumptions, labeled ranges, and clear separation between educational estimators and professional advice.
