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.
Calculate the mark up percentage on the product cost, the final revenue or selling price and, the value of the gross profit.Enter the original cost and your required gross margin to calculate revenue (selling price), mark up percentage and gross profit.This calculator is the same as our Price Calculator. The gross profit P is the difference between the cost to make a product C and the selling price or revenue R. 2  P = R-C. 3  To calculate revenue R based on the cost C and the desired gross margin G, where G is in decimal form: 4  R = C / (1 - G).
