Banks are either hated or loved, depending on when you ask customers. If they’ve been approved for that loan or denied a refund of any fee, you will get different answers. As a value investor, banks and financial institutions can be a frustrating experience to try to value. They don’t fall into the same category that other companies do, so therefore they often get ignored. Today we will continue with our series of looking at the different formulas that can help us unravel the mysteries of these institutions. In this post, we will delve into the efficiency ratio and what it means, and how to calculate it.

“In the end, banking is a very good business unless you do dumb things.”

Warren Buffett

The cool thing about learning to value banks is that once you learn how to analyze one, you pretty much can analyze all of them. There are about 500 banks that trade on the major exchanges, so this should give you plenty of options to choose.

Now, don’t get me wrong they can be very complicated with all the financial instruments, heavy regulations, old account rules, macro factors, and the intentionally vague jargon to try to throw you off.

But at their core, all banks are similar in that they borrow money at one interest rate and then hopefully, lend it out at a higher interest rate, pocketing the spread between the two. Which is the main avenue that banks use to make money.

“You don’t make money on tangible common equity. You make money on the funds that people give you and the difference between the cost of those funds and what you lend them out on.”

Warren Buffett
