Let's run a quick P&L on this:
-Annual revenue $5MM
-Blended product/service margin 15% (just an assumption based on knowledge of similar businesses I work with)
-We are left with $750K to cover COGS and all overhead. Let's assume $100K for rent, utilities, insurance, write-offs,...list goes on ($100k is very conservative)
-Add 10 employees at $50K a pop (more like $75K after benefits) and you're left sweet Fvck all
So yes, revenues are completely irrelevant when it comes to the health of a business ,EBITDA is where it is at
Yup, the TSX venture exchange (heck, even on the regular TSX), there are many companies which have revenues in the 50 million or more (sometimes hundreds of millions), but they still have no earnings/profit. In other words, they are still paying out more than they take in. Lots of startups are like this but even some companies that have been around for a few years. You can't look at revenue alone for a clear picture of financials. For those who may not know, EBITDA is Earnings Before Interest, Taxes, Depreciation and Amortization.
I have two family members - one has an MBA, makes 180K a year, has a big house and a nice car, but is significantly in debt to keep up with the Joneses. His net worth is very low, despite what the social optics may seem. The other is a regular Joe, has a 80K job, small bungalow, old Toyota 4 Runner, wears sweatpants that have thinned out to pantyhose quality, and yet he is a millionaire many times over due to shrewd investments, living way below his means and no debt.
Sometimes, things are not quite how they seem.
At our workplace, we have project managers making from 50K all the way to 260K. That is a very wide variance, but as others have said, that is based on experience, qualifications, etc. The average project manager out there may see the 50K starting salary and think it is an insult. But based on the job climate with covid, their own circumstances, and their ability to prove themselves or get their foot in the door, they may decide to take the job. They won't stay at the starting wage for long if they are that good and the company wants to retain them.
Also bear in mind with increased operating costs such as higher wages, this most certainly will be passed on to the consumer. I remember talking with people years ago and they were saying how disgusting it is that most of our clothing manufacturing has been farmed out to third world counties and cheap labour, and they were saying how all this should come back to Canada and the US. I remind them that if this was the case and we are now paying whatever minimum wage in Canada/US to pay people to make clothing, the average cost of a t-shirt will probably be like $50.00 instead of $10 or $15 (or lower). Before covid, I worked in a very very fancy state of the art corporate office tower. It was owned by our client, a global financial services company. Their fees and prices are much higher than similar companies, and this is not surprising, since their sales force is compensated very well and the corporate amenities are quite nice. Having higher operating costs will lead to higher prices to the consumer.
Companies have a right to pay whatever they feel is fair. As always the law of supply and demand would dictate compensation. If no one applies, they may increase the starting compensation offer. It is at each company's discretion. They are the ones who have to mind their bottom line.
