Commerical banks have a large weightage of debt from deposits, which has a very low interest rate. This caused our calculated WACC to be very low. Is this correct? https://docs.google.com/spreadsheets/d/1Cq2qiVEetbNP65fYnxYvJsfViBKLNT8p5GW0GkMkhGc/edit#gid=416987316
Or should we omit customer deposits from our calculation of WACC? Sites like Gurufocus cite a more reasonable value for WACC at around 5% - 12%, which disagrees with our calculations.
