Some employers pay you an annual salary rather than an hourly wage. Often, employers give you a raise or a pay cut as a percentage of your current salary rather than as a flat dollar amount. For example, an employer might grant an across-the-board raise of 5 percent when the company is doing well. To figure the equivalent dollar amount of a percentage of your salary, you just need to know the percent and your salary.

Divide the percentage by 100 to convert it to a decimal. For example, if you want to figure 12 percent of your salary, divide 12 by 100 to get 0.12.

Multiply the decimal result by your salary to find the percentage of your salary. In this example, if your salary equals $39,000, multiply $39,000 by 0.12 to get $4,680.

Add the result to your salary to figure your new salary after a raise or subtract the result from your salary to figure your new salary after a pay cut. In this example, if you expect a 12 percent raise add $4,680 to $39,000 to find your new salary: $43,680.
