My VTC was cast before the current edit, but I believe my issues remain
Before I begin, it's important to realize that few of us see more than about 20% of the questions that pass through this Stack. That means that there's precious little consistency in the closing-and-reopening process because we all have different views concerning why things should be closed. Consequently, it's unreasonable to point to any other question(s) suggesting that yours should remain open since theirs did. What's most likely to happen is that I'll go vote to close those questions because they violate my interpretation of the rules. You're asking about your question. Nobody else's question establishes precedent for or against your need.
Let's start with the basic problem. You've created a vaguely-defined tool based on nearly 50 year old tech and placed it in the modern world and asked us to explain, of all things, how profitable it can be.
How should we know? If I buy a hammer and put it in a tool box and never use it, then its profitability is zero. If I use it to build my house, technically it's profitability is till zero. If I sell the house and the hammer was the only tool I used, then the difference between the house's sell price and its construction price could be called the profitability of the hammer (but it likely wouldn't because I wouldn't get the best benefit from taxes if I did that...). If I use it to bash in the head of Adolf Hitler before the Nazis stormed Poland, its profitability would be beyond price.
Did you see the problem? Profitability is based on the circumstances surrounding the use of the tool. It has nothing at all to do with the tool itself.
Worldbuilding (on-topic) is the development and consistent use of the rules governing a fictional world of your own creation.
Storybuilding (off-topic) is the development of plot, circumstances, and character choices and actions.
And it doesn't matter what the tool is. Back during the cold war my father had a saying, "a weapon unused is a useless weapon." What's the profitability of an ICBM? I dunno, what's the value of peace? How do you put a price on it? Even a house is only as valuable as what the buyer is willing to pay for it. What are the conditions and limitations of the buyer? Are they wealthy, middle-class, or poor? Do they have a large savings account? a retirement account? a wealthy uncle? Or just enough for a down payment? What is the condition of the economy involving the buyer and the seller at that time? How much does the seller have invested in the house? Is the house in a desirable area? Is it in good repair?
More problems... there are so many variables that define "profitability" and all of them are a function of the circumstances of your story — not a rule of your world.
Specifically in terms of your question, one way of looking at profitability is a computer's profitability can be judged in relation to the value of the data it manipulates. If a simulation will lead to a million-dollar deal, then the computer that completed that simulation has a profitability of a million dollars. If it's being used to process SETI signal analyses, its profitability is zip until an alien culture is actually found (and then it could be said that it was still zero).
Another way of looking at profitability is the computer's profitability can be judged by the rental value it has. In other words, the owner spent \$X to make the computer ready for people to rent. He then chooses (see "storybuilding" above) \$Y such that \$Y-\$X = profitability.
Establishing the profitability of any tool is not a basic economics question. It's a circumstantial question that demands that we begin writing your story for you (the essence of "too story-based"). it requires us to invent circumstances to justify the perception of value. And that's off-topic.
