## Mind on the Money

When I think of business, I think of money. The whole point of a business is to earn money for your product or service. In the simplest terms, the money you bring in is revenue, the money you spend is your costs, and the difference between the two is profit. Profit is key. You want a lot of that. Understanding how to calculate profit margin, or profit markup, can be important to any business owner, or employee.

## An Interest in Math

I have always been told that interest is a good thing. As long as you're the one earning interest. This day in age, it's difficult to imagine a single day that I don't have to consider interest. It's involved with loans, credit cards, bills, calculating a return on investments, and even your every-day bank accounts. If you've ever heard of the time value of money, that is where interest comes from. Interest is a charge for the use of someone else's money. It's usually a percentage of the original amount of money that is being used. So, as I said before, interest is good, if you're earning it.

## Keep it Real... Estate

Real estate is a business market that heavily involves math. You have the revenue, cost and profits of your transactions, as well as percentages for the commissions, cost of a mortgage, the math used in taxes and capital gains, as well as a lot of geometry involved in the areas and rates associated with property size and cost-per-square foot. If you've ever purchased a home, or are looking into purchasing a home, you need to be aware of the calculations involved. Having an understanding of the math associated with the real estate market could end up paying off in actual dollars and cents later on.
