The "Total Revenues" for banks are calculated as: Net Interest Income + Total Non Interest Income - Provision for Loan Losses. This formula doesn't provide actual total gross revenues for banks, and given that these "Total Revenues" are used for calculating the net income margin, it distorts and shows a banking sector that is much more profitable than it actually is. Tradingview's "Total Revenues" of banks metric includes all gross revenues without deductions for expenses, making its net income margin formula for banks comparable between sectors in contrast with the one Koyfin uses.
