A paycheck may look like a simple number on paper, but there’s quite a bit behind it. An employee works 40 hours, earns an hourly rate, and expects to be paid the right amount. Yet, the final paycheck must account for overtime, tax withholding, benefits, and other deductions. That’s why payroll for dummies is a useful starting point for anyone who wants to understand what goes into paying employees.
Payroll doesn’t have to be hard to follow. Once you know how wages, taxes, and deductions fit together, you can see exactly how an employee’s gross pay turns into take-home pay. This blog explains the basics, shows how to calculate employee payroll with simple examples, and covers the key rules every new employer should know.

What Is Payroll? A Beginner-Friendly Explanation
Payroll is the process a business uses to pay its employees for the work they do. It includes tracking hours, working out wages, taking out taxes and other deductions, paying staff, and keeping records of each pay run.
For example, if a worker earns $25 an hour and works 40 hours in a week, their gross pay is $1,000. The amount they take home will be lower after tax and other required deductions.
A payroll cycle often follows these steps:
- Collect work hours, salary data, and any extra pay.
- Work out each employee’s gross pay.
- Apply tax withholdings and approved deductions.
- Work out the employee’s net pay.
- Send payments through direct deposit or check.
- Record the pay run and meet tax filing and deposit duties.
For a new employer, payroll for dummies starts with one key idea: gross pay is not the same as take-home pay. You must account for both employee deductions and the taxes the business owes.

Understanding the Basic Components of Employee Payroll
Before learning how to calculate employee payroll, you need to know the main parts of a paycheck. Each one has a role in the final amount paid to an employee.
Payroll component | What it means | Example |
Gross pay | Total earnings before any deductions | $2,000 |
Federal income tax | Tax withheld from wages based on Form W-4 and IRS rules | $180 |
Social Security tax | Employee share of Social Security tax | $124 |
Medicare tax | Employee share of Medicare tax | $29 |
Health insurance | Employee’s share of plan cost | $75 |
Net pay | Amount paid after deductions | $1,592 |
The figures are for illustration only. Actual tax withholding depends on the employee’s Form W-4, pay period, taxable wages, and other factors.
Gross pay: This is the full amount an employee earns before taxes or deductions. It may include hourly wages, salary, overtime, bonuses, and commissions.
Net pay: Also called take-home pay, this is what remains after the required taxes and other valid deductions are taken out.
Payroll taxes: These include federal income tax withholding, Social Security, Medicare, and, in some cases, state and local taxes.
Employee deductions: These may include health plan costs, retirement plan contributions, and wage garnishments. Some are taken out before tax, while others are taken out after tax.
Employer-paid taxes: Businesses also pay certain payroll taxes. These are separate from the amounts taken from an employee’s check and must be added to the employer’s payroll cost.
Understanding these parts makes payroll for dummies easier because you can see where each dollar goes.
How to Calculate Employee Payroll Step by Step
If you’re learning how to calculate employee payroll, start with the employee’s gross pay and then work through each tax and deduction. Here is a simple example for a worker paid by the hour.
Step 1: Work out gross pay
Suppose an employee earns $20 per hour and works 40 hours in one week.
40 hours × $20 = $800 gross pay
Add any overtime, bonus, or commission that applies to the pay period.
Step 2: Check taxable wages
Not every type of pay or benefit is treated the same way for tax purposes. Review the employee’s earnings and any pre-tax benefits before working out each tax amount.
Step 3: Work out payroll tax withholding
For 2026, the employee share of Social Security tax is 6.2%, up to the annual wage limit of $184,500. The employee share of Medicare tax is 1.45%, with no wage cap.
For the $800 example:
- Social Security: $800 × 6.2% = $49.60
- Medicare: $800 × 1.45% = $11.60
Federal income tax must be worked out using the employee’s Form W-4 and the IRS withholding method. State and local tax rules may also apply.
Step 4: Apply other deductions
Take out any valid employee deductions, such as health insurance or retirement plan contributions. Check whether each deduction is pre-tax or post-tax, since this can affect taxable wages.
Step 5: Calculate net pay
Use this basic formula:
Net Pay = Gross Pay − Employee Taxes − Other Employee Deductions
For example, if gross pay is $800, total employee tax withholding is $120, and other deductions are $50:
$800 − $120 − $50 = $630 net pay
The $120 is an illustrative tax amount, not a tax estimate for a specific employee.
Step 6: Review and record the pay run
Check hours, rates, deductions, and tax amounts before sending payment. Save pay stubs, payroll reports, and tax records. This helps you answer employee questions and fix errors if they arise.
How to Calculate Payroll for Hourly and Salaried Employees
The way you work out employee pay depends on whether the worker earns an hourly rate or a fixed salary. Both methods start with gross pay, but the steps can differ.
1. Payroll Calculation for Hourly Employees
For hourly workers, multiply the hours worked by the agreed hourly rate. Add overtime pay and any other earnings that apply.
Example:
An employee earns $22 per hour and works 45 hours in one week.
Pay details | Calculation | Amount |
Regular pay | 40 × $22 | $880 |
Overtime pay | 5 × $33 | $165 |
Gross pay | $880 + $165 | $1,045 |
This example uses 1.5 times the regular hourly rate for overtime. Under federal law, covered, nonexempt employees must receive at least this rate for hours worked over 40 in a workweek. Some state laws may set higher standards.
2. Payroll Calculation for Salaried Employees
Salaried employees earn a set amount, usually paid weekly, biweekly, or monthly.
For example, if an employee earns $52,000 per year and gets paid every two weeks:
$52,000 ÷ 26 = $2,000 gross pay per paycheck
You then apply the right tax withholdings and other deductions to work out net pay.
Keep in mind that being paid a salary does not automatically make someone exempt from overtime. Their job duties and pay must meet the applicable legal tests.
How Are Payroll Taxes Calculated in the United States?
Payroll taxes are a key part of payroll for dummies because employers must know which taxes to take out of employee pay and which taxes they must pay themselves.
In the United States, common federal payroll taxes include:
Tax | Employee share | Employer share |
Social Security | 6.2% | 6.2% |
Medicare | 1.45% | 1.45% |
Federal income tax | Based on Form W-4 | Not paid as a matching employer tax |
FUTA | None | Generally 6% on the first $7,000 of each employee’s wages, before applicable credits |
For 2026, Social Security tax applies to wages up to $184,500 per employee. Medicare tax has no wage limit. Employers must also withhold an extra 0.9% Medicare tax from an employee’s wages once they exceed $200,000 in a calendar year. This extra tax is paid by the employee, not the employer.
Here are the main taxes to know:
- Federal income tax: Employers withhold this from employee wages based on the worker’s Form W-4 and IRS tax tables.
- Social Security tax: Both the employer and employee pay 6.2% of taxable wages, subject to the annual wage limit.
- Medicare tax: Both parties pay 1.45% of taxable wages.
- Federal Unemployment Tax (FUTA): This is an employer-paid tax that helps fund unemployment programs. The general rate is 6% on the first $7,000 of wages, but eligible employers may claim a credit of up to 5.4%.
State and local taxes may also apply. These can include state income tax, state unemployment insurance, and local payroll taxes. The rules depend on where the employee works.
A common mistake in payroll for dummies is to treat all payroll taxes as employee deductions. FUTA, for example, is an employer cost and should not be taken out of an employee’s paycheck.
Payroll Compliance: Important Records, Forms, and Filing Deadlines
Running payroll means more than working out wages and sending payments. Employers must also file the right forms, deposit taxes on time, and keep records that support each pay run.
Here are some common payroll forms used by US businesses:
Form | Purpose |
Form W-4 | Records an employee’s federal income tax withholding details. |
Form I-9 | Verifies an employee’s identity and authorization to work in the US. |
Form W-2 | Reports an employee’s yearly wages and taxes withheld. |
Form 941 | Reports federal income tax withholding and Social Security and Medicare taxes, generally each quarter. |
Form 940 | Reports the employer’s annual federal unemployment tax. |
Employers should also track:
- Employee names and contact details.
- Hours worked and pay rates.
- Overtime hours and extra pay.
- Tax withholdings and other deductions.
- Gross wages and net pay.
- Pay dates and the periods covered.
The Department of Labor requires covered employers to keep accurate wage and hour records. In general, payroll records must be kept for at least three years, while records used to work out wages, such as time cards, should be kept for two years.
Important payroll deadlines:
- Form 941 is generally due by April 30, July 31, October 31, and January 31.
- Form 940 is generally due by January 31.
- Form W-2 must generally be sent to employees and filed with the Social Security Administration by January 31.
Federal tax deposit dates depend on the employer’s deposit schedule. Some businesses must deposit taxes monthly, while others must do so more often. Always check the latest IRS rules and any state filing requirements before setting your payroll calendar.

Our Expert Insight
One detail new employers often overlook is the difference between an employee’s paycheck and the actual cost of keeping that employee on the payroll. For example, an employee earning $2,000 in gross wages costs the business more than $2,000 once the employer’s share of Social Security, Medicare, unemployment taxes, and other employer-paid benefits is included.
At Meru Accounting, we recommend reviewing payroll through both the payroll register and the general ledger. Employee wages, employer-paid taxes, benefit costs, and outstanding payroll liabilities should be recorded in the right accounts and match the payroll reports. This gives business owners a more accurate view of labor costs, helps catch accounting errors, and makes it easier to plan future payroll expenses.
