Key terms in Three ways to divide a month

Fixed expenses

Fixed expenses are bills that must be paid each month and generally cost the same amount each time. Rent or a mortgage payment, an insurance premium and a loan installment are typical examples. Because the amount rarely changes, fixed expenses are the easiest part of a budget to predict, in contrast to variable expenses.

Pay period

A pay period is the span of time for which an employer calculates and pays wages. The Bureau of Labor Statistics identifies four common lengths: weekly, biweekly (every two weeks), semimonthly (twice a month), and monthly. Biweekly is the most common among private employers in its survey, and the length varies by industry and by the size of the business.

Net pay

Net pay is the amount of a paycheck that remains after taxes and other deductions are taken from gross pay. It is the figure a worker actually receives, and it is often smaller than the amount earned. The gap reflects tax withholding, which depends partly on the information given on Form W-4, and may also include deductions for benefits.
