- 1). Divide your gross annual salary before deductions by 365.
- 2). Multiply the figure you arrive at by the number of days in your pay period. If you receive a weekly paycheck, multiply by seven. If you're paid biweekly, multiply by 14. You will be left with your gross paycheck value.
- 3). Subtract income tax and other deductions to calculate your net income per paycheck. The amount of income tax you pay will depend on your personal circumstances. A single worker earning up to $8,500 is liable to pay 10 percent of his income to the government in income tax. A single person or a married couple earning more than $379,150 pay 35 percent in income tax in the 2011 tax year.
