As long as we all remember that you are the uneducated rube in the equation. You could have said "thank you" but you consider helpful information that doesn't come from your slave-masters to be offensive.
Once again, we take a step back and remember that you are not an MBA or an economist of any type, and being a leftist you tend to lash out like this whenever you are greatly confused. Don't worry, cooler (and more educated) heads will prevail and will help you through your total dumbass stages. Feel free to take notes on everything I teach you, unless your slave-masters prohibit such; I wouldn't want you to get into any trouble as you are being bent over furniture.
Whenever you are projecting future rates of return,
you select a rate that
you believe is reasonable. Oh look, the S&P 500 Index average yearly return over the last ten years (as of the end of June 2023) is 12.39%. Any rational adult considering investment options for, say, $22,000 would be wise to at least consider a projected value of 12.39% annual growth for an S&P 500 Index investment, and include that information amongst other considered options as a comparison figure.
Also, one has to estimate a reasonable value for the rate of inflation. I used 2.5% but you can use any value that you find reasonable for your calculations. Just make sure to use the same inflation rate value for all investments being considered, otherwise you lose your apples-to-apples comparison.
By the way, if you think I'm going to look like a fool discussing economics, accounting and financial markets, you should see how you look. Too funny. Take notes. Really. I can't emphasize that enough. Oh, and don't be afraid to ask
Into the Night for his business investment insights. You could come away with a few pearls of wisdom there.
Exactly, it's all speculation, which is why you need to give it some thought and come up with what you believe are reasonable projection values.
Nope. How much do you have to pay up front? How much do you pay to buy the system? That is the amount you project as your investment value for your different investment options.
You can include subtractions to your Net Present Value for electric bills that you have to pay. Instead of being $93,000 wealthier for simply investing in the S&P Index and paying your electric bills outright, you can factor in the savings provided by the system to get a more accurate value of being only $72,000 wealthier for simply investing in the S&P 500 Index and paying your electric bills outright.
This is fun. Anytime you want to talk economics or accounting, just let me know. My rates are competitive.
