ROI calculations

I’ve been quiet all week because we merged two of our restaurant locations. I was sad bcz we had that particular location for 15 years. 
It was in my hometown and we had 2 locations in my hometown. We had an offer we couldn’t refuse on the real estate so it was time to depart. Side note**the cannabis boom is happening right now in Oklahoma and real estate is going for insane prices.
So that got me thinking about ROI and numbers. I love numbers! I have heard people talk in this group about profit, loss, return on investment, etc. So here’s my take on it since I’m in several industries aimed to help people think more freely, work more passionately and live more purposefully! 
The ROI is amazing on creative work/inventions/books if you come out with a long-lasting Seller! The investment is worth it if you believe in your art. To all of you sitting on the fence and scared, here’s my advice—-Go for it! What have you got to lose? Your pride?! Your money?! 
I once lost $180,000 in a restaurant. The lessons I gained were priceless. How? Here’s proof: My very next restaurant I opened right after that closure was the biggest success I’ve ever had to date and that restaurant recouped it’s initial investment in 6 months. To read more about this and the numbers, go to my next post.

These are real life examples from my own experience. I chose an average investment from each industry in my portfolio. My goal is to show you the potential that you hold in your hands right now. 
Please note this is a simplified version of annual ROI to compare different investment vehicles. These numbers are standard in the industry or better. These numbers are mine and I can’t be held accountable for your ROI. (My specialty is restaurants and real estate with over 20 years+ experience.)
Please note that the book royalties are estimated based on my experience within the past 3 months.

I understand there are plenty of ways to calculate ROI. This is my simplified version so I can quickly calculate in my head when I’m making a potential offer/investment. To find my simplified annual ROI, here’s what I did. 
Subtract all expenses from monthly income to find net profit/monthly cash flow. Then divide monthly cash flow by amount of investment. Finally, multiply by 12. You will then have a number in decimals. Multiply by 100 to receive your ROI percentage.
