With the Commonwealth Bank of Australia (ASX: CBA) currently trading around $97, let’s run through two standard share price valuation tools an analyst might use to provide his or her valuation on an ASX bank share like CBA.
As you may know, this is the standard version. Keep in mind, standard doesn’t necessarily equal ‘good’. So, at the bottom of this article, we’ll provide some further resources to complement our potential indicative valuations. Basically, it goes without saying but these valuations are not guaranteed.
Bank shares like Commonwealth Bank of Australia, ANZ Banking Group (ASX: ANZ) and Macquarie Group Ltd (ASX: MQG) are very popular in Australia because they tend to have a stable dividend history, and often pay franking credits.
In this article, we’ll explain the basics of investing in ASX bank shares. But if you’re interested in understanding the value of dividend investing in Australia (i.e. the benefits of franking credits), check out this video from the education team at Rask Australia.

How to use PE ratios
The price-earnings ratio, which is short for price-to-earnings, is a basic but popular valuation ratio. It compares yearly profit (or ‘earnings’) to today’s share price ($97.37). Unfortunately, it’s not the perfect tool for bank shares, so it’s essential to use more than just PE ratios for your analysis.
That said, it can be handy to compare PE ratios across shares from the same sector (banking) and determine what is reasonable — and what isn’t.
If we take the CBA share price today ($97.37), together with the earnings (aka profits) per share data from its 2020 financial year ($4.706), we can calculate the company’s PE ratio to be 20.7x. That compares to the banking sector average PE of 23x.
Next, take the profits per share (EPS) ($4.706) and multiply it by the average PE ratio for CBA’s sector (Banking). This results in a ‘sector-adjusted’ PE valuation of $107.64.
A simple guide to valuing CBA using dividends
A DDM is a more interesting and robust way of valuing companies in the banking sector, given that the dividends are pretty consistent.
DDM valuation modeling is one of the oldest methods used on Wall Street to value companies, and it’s still used here in Australia by bank analysts. A DDM model takes the most recent full year dividends (e.g. from last 12 months or LTM), or forecast dividends, for next year and then assumes the dividends grow at a consistent rate for a forecast period (e.g. 5 years or forever).
To make this DDM easy to understand, we will assume last year’s dividend payment ($3.50) grows at a consistent rate into the future at a fixed yearly rate.
Next, we pick the ‘risk’ rate or expected return rate. This is the rate at which we discount the future dividend payments back to today’s dollars. The higher the ‘risk’ rate, the lower the share price valuation.
We’ve used an average rate for dividend growth and a risk rate between 6% and 11%.
This simple DDM valuation of CBA shares is $66.72. However, using an ‘adjusted’ dividend payment of $3.98 per share, the valuation goes to $71.34. The expected dividend valuation compares to Commonwealth Bank of Australia’s share price of $97.37. Since the company’s dividends are fully franked, you might choose to make one further adjustment and do the valuation based on a ‘gross’ dividend payment. That is, the cash dividends plus the franking credits (available to eligible shareholders). Using the forecast gross dividend payment ($5.69), our valuation of the CBA share price guesstimate to $101.92.
Where to from here
Simple valuation models like these can be handy tools for analysing and valuing a bank share like Commonwealth Bank of Australia. And while these models can even make you feel warm and fuzzy inside because you have ‘put a value on it’.
That said, it’s far from a perfect valuation (as you can see). While no-one can ever guarantee a return, there are things you can (and probably should) do to improve the valuation before you consider it as a worthwhile yardstick.
For instance, studying the growth or increase in total loans on the balance sheet is a very important thing to do: if they’re growing too fast it means the bank could be taking too much risk; too slow and the bank might be too conservative. Then, study the remainder of the financial statements for risks.
Areas to focus on include the provisions for bad loans (income statement), their rules for assessing bad loans (accounting notes) and the sources of capital (wholesale debt markets or customer deposit). On the latter, take note of how much it costs the bank to get capital into its business to lend out to customers, keeping in mind that overseas debt markets are typically more risky than customer deposits due to exchange rates, regulation and the fickle nature of investment markets.
