Is it possible to calculate the IRR on a bank loan facility ?
It would not make much sense to attempt an IRR on a bank loan facility or line of credit. The problem is that you need an investment to balance the positive cash flow against. However, you can perform an investment rate of return analysis on the projects that you finance with the bank's money. If your IRR result is greater than the cost of money(interest rate on the borrowed money) then you can say that it is a great deal. The IRR should be used as the yardstick to compare possible projects.
