Sometimes a radio program is added to the carrier in such a way that the program signal causes fluctuations in the carrier's frequency. This is called frequency modulation (FM). Another way of sending a radio signal is to make the peaks of the carrier wave bigger or smaller.
Calculating the percentage profit made. It is also possible to work out the percentage profit that is made on a deal. This is done using the profit and the price that something cost originally, before it was sold on (the Cost Price). Percentage Profit = (profit/cost price) x 100%. The next example shows how this is done. Example.
Once you have decided on the retail pricing of your products, compare the sales prices with the wholesale costs to determine your expected profit margin. Profit margin can be listed both in dollar terms and as a percentage. For example, a product will sell for $25 each and your wholesale cost is $10.The profit margin will be $15 per sale. As a percentage, the profit margin is 15 divided by 25, or 60 percent. Profit margin is always calculated from the retail price and is the money coming in to run your business.he math to convert profit margin percentage to markup percentage is to divide the wholesale price by one minus the profit margin percentage. For the $25 item that cost $10, the $10 would be divided by one minus 0.60 -- the profit margin -- or $10 divided by 0.40, which equals $25.
