The numbers are interesting. As you could guess, it is a bar, a few blocks away from Wrigley Field. In 1946 the average family income was about $2,600 per year or $216.66 per month. The profit for this month was $155.78. Previous month's profits averaged $670.
Why was this month so low? As I looked at the details of the financials, I saw that he bought additional beer this month. Maybe there was a deal, or added a new brand.
Having monthly financial statements are important for a business. They answer questions you might have. Can you take advantage of a suppliers' deal? Will purchasing equipment be a better advantage this month or next?
What is your business worth? I did a quick Valuation of my Grandfather's business, based on the financials we found. At the beginning of 1946, it would be worth about $28,140. In June 1946, it would be worth over $40,000. What do you think a major factor was in the increase in the business value in those first 6 months of 1946? (Hint: When was the last time the Cubs were in the World Series?)
