What interest rate will I be charged for a generic loan if I walked into a bank today?

I need the market interest rate for the past three years for an analysis, but have got no idea where to get the data...I keep coming across federal rates and prime rates which have been constant for the past three years and know these are being used as a basis for calculating all other rates...would be great if someone could elaborate and point me in the right direction as to where to find the data...Thanks!|||It depends on the type. If it's a commercial mortgage you could find rates as low as 5.5%.|||The rate varies from bank to bank.It may depend on how much you borrow,the length of the loan and whether the loan is secured or not.
