Suppose your firm is seeking a five-year, amortizing $900,000 loan with annual payments and your bank is offering you the choice between a $950,000 loan with a $50,000 compensating balance and a $900,000 loan without a compensating balance. If the interest rate on the $900,000 loan is 9.5 percent, how low would the interest rate on the loan with the compensating balance have to be in order for you to choose it?
