Explain the factors that determine income and read an employee earnings statement from gross wages to net pay

Learning goal: Explain how income is determined by many factors, including individual skills and abilities, work ethic and market conditions, and read an employee earnings statement, identifying gross wages, benefits, taxes and other deductions and computing net pay.

What income is. Income is money received over a period. For most people most of it is earned income, pay received in exchange for work, as wages (paid per hour) or salary (a fixed amount per year, paid in installments). People also receive income from interest, dividends, rent, profit from a business, and government transfers. This lesson focuses on earned income, because it is where most students begin.

Factor 1: individual skills and abilities. Employers pay for what a worker can produce. Skills acquired through education, training, apprenticeship and experience make a worker more productive, and economists call that accumulated knowledge and skill human capital. A licensed electrician, a nurse or a welder certified in a specialized technique can do work that fewer people can do, and scarcer skills in demand tend to earn more. Abilities, such as physical strength, communication, or aptitude with numbers, also matter, though many abilities grow with practice. Investing in human capital has costs, such as tuition and time not spent earning, so a student deciding on training is weighing costs and benefits.

Factor 2: work ethic. Work ethic is the set of habits and attitudes a worker brings: showing up on time, completing tasks carefully, taking initiative, learning from feedback and cooperating. Work ethic affects income mainly over time. A reliable worker is more likely to be offered more hours, raises, promotions and strong references, and less likely to be let go. Two people with the same skills can end up with different incomes because of differences in reliability and effort.

Factor 3: market conditions. Wages are prices, the price of labor, and they respond to supply and demand in labor markets. When many employers want workers with a particular skill and few people have it, wages for that skill rise; when many people can do a job and few employers are hiring, wages stay low. Market conditions include the state of the overall economy (in a recession, fewer employers hire), the industry (a growing industry bids for workers), the location (wages and living costs vary across regions and between cities and rural areas), and technology (automation may reduce demand for some tasks and increase demand for others). Laws also shape pay: under the federal Fair Labor Standards Act, most hourly employees must receive at least one and one-half times their regular rate for hours worked over 40 in a workweek, and minimum wage laws set a floor. No single factor determines income; they interact.

The earnings statement. An employee earning statement, often called a pay stub, accompanies each paycheck or direct deposit and reports the pay period, hours, rate, and every amount added and subtracted. It includes four kinds of information.

Gross wages (gross pay) are total earnings before anything is taken out: hours × hourly rate, plus overtime, commissions or bonuses.

Taxes withheld. Federal income tax withholding depends on earnings and the information the employee gives the employer on Form W-4. Social Security and Medicare taxes (together called FICA) are withheld at set rates; for employees the Social Security rate is 6.2% (up to an annual wage limit) and the Medicare rate is 1.45% (plus an additional 0.9% withheld on an employee's wages above 200,000 dollars in a year), and the employer pays a matching amount of the 6.2% and 1.45%. Ohio also levies a state income tax, and many Ohio cities and villages levy a local income tax, so an Ohio pay stub often shows state and city withholding.

Other deductions include the employee's share of a health insurance premium, contributions to a retirement plan, union dues or wage garnishments.

Benefits are compensation beyond wages: health insurance, retirement contributions, paid time off. A stub may show the employer's share of benefit costs and paid time off earned, which are part of total compensation even though they are not in the paycheck.

Net pay (take-home pay) = gross wages − taxes − other deductions.

A fully worked model. An invented stub for a hypothetical worker, Dana, for one two-week pay period: 36 hours at 15.50 dollars an hour, so gross wages = 36 × 15.50 = 558.00 dollars. Withheld: federal income tax 38.00 (an invented amount; real withholding depends on the W-4 and the tax tables); Social Security 6.2% × 558.00 = 34.596, rounded to 34.60; Medicare 1.45% × 558.00 = 8.091, rounded to 8.09; state income tax 12.50 (invented); city income tax at a hypothetical 2%, 0.02 × 558.00 = 11.16. Other deduction: health insurance premium, employee share, 18.00 (treated as after-tax in this invented stub; many real plans take premiums before tax, which changes the tax amounts). Total deductions = 38.00 + 34.60 + 8.09 + 12.50 + 11.16 + 18.00 = 122.35. Net pay = 558.00 − 122.35 = 435.65 dollars. The stub also shows benefits: the employer paid 45.00 dollars toward Dana's health plan, and Dana earned 1.5 hours of paid time off. Dana's take-home pay is about 78% of gross, which is why a budget must start from net pay, not gross.

The misconception. Many new workers budget from their hourly rate times hours, then find the deposit is smaller. Gross is not what you keep. Another misconception is that benefits are "free"; they are part of what an employer pays for your labor.

Worked example 1 — gross to net: Hypothetical: 36 hours × 15.50 = 558.00 gross. Deductions: 38.00 federal (invented), 34.60 Social Security (6.2%), 8.09 Medicare (1.45%), 12.50 state (invented), 11.16 city (hypothetical 2%), 18.00 health premium. Sum 122.35. Net 558.00 − 122.35 = 435.65 dollars. Check: 435.65 + 122.35 = 558.00.

Worked example 2 — overtime: A hypothetical hourly worker covered by the overtime rule earns 15.50 dollars and works 44 hours in one workweek. Regular pay 40 × 15.50 = 620.00. Overtime rate 1.5 × 15.50 = 23.25; overtime pay 4 × 23.25 = 93.00. Gross wages 713.00 dollars. The common error is to pay all 44 hours at 15.50 (682.00), which understates gross by 31.00.

Worked example 3 — explaining an income difference: Two hypothetical workers apply for warehouse jobs. One holds a forklift certification (skill) and has a record of perfect attendance (work ethic); the other has neither. In a region where several new distribution centers are hiring (market conditions), the first is offered 2.00 dollars more per hour and a lead role within a year. In a region where warehouses are closing, both might receive lower offers or none. The same skills and effort earn different amounts under different market conditions.

Earnings statement record: Using the invented stub in the diagram, list each line under one of four headings: gross wages, taxes, other deductions, benefits. Recompute every percentage deduction yourself, add the deductions and confirm net pay. Then compute what share of gross pay Dana takes home.

Independent performance: Research a career you are considering, using a reliable public source such as a government occupational outlook handbook. Write a one-page explanation of the factors that determine income in that career and build an invented earnings statement for one pay period. Success criteria: you explain at least one skill or ability, one work-ethic habit and one market condition that affect income in that career, with the source of any wage figure named; your invented stub shows hours or salary, gross wages, Social Security at 6.2% and Medicare at 1.45%, at least one other tax and one other deduction clearly labeled hypothetical, and at least one benefit; and your net pay is computed correctly.
