What Are Gratuities and Commissions, Fees, and Tax? Kids use gratuities, commissions, fees and tax to solve their everyday problems. What most kids don't realize is that solving them requires the same steps to a certain level. While some of these terms are not used on a daily basis, it generates a perception that it requires complex calculations. First, let us look at the tax and commission part. Some common steps are involved in both: - First, you convert the percentage into decimal - Then multiply that decimal with the cost, which will get you the amount of tax and commission. Using tax and commission, people usually calculate the whole cost or income of a person. The resulting amount will then be added to the whole cost, and that will get you the total amount to be paid. Gratuities are often considered a tip and use synonymously, but if you receive the bill and it has already added Gratuity or service charge, then there is no need to give a tip.
