How to Calculate Employee Gross Pay

Gross pay is the starting number for every paycheck. It is the total amount an employee earns for a pay period before any withholdings or deductions come out. When gross pay is right, the withholdings, deductions, and net pay that follow all calculate from a correct base. When gross pay is wrong, every line below it is wrong too.

This guide explains how to calculate employee gross pay for hourly and salaried staff, including how hours, overtime, and salary splits work together. If you are newer to payroll altogether, it helps to start with our guide on payroll processing basics before you dig into the math.

What Is Employee Gross Pay?

Employee gross pay is the full amount an employee earns for a pay period before taxes, withholdings, and deductions are taken out. It is the top line on a paycheck, and it is the number every other payroll line builds from. Net pay, by contrast, is what is left over after everything comes out.

The way you calculate gross pay depends on how the employee is paid. Hourly employees earn gross pay based on the hours they work and their hourly rate. Salaried employees earn gross pay based on their annual salary split evenly across pay periods. The method changes, but the idea stays the same: gross pay is the earned amount before anything is withheld. For a closer look at how gross pay becomes net pay, see our guide on gross pay vs net pay.

How to Calculate Hourly Gross Pay

For an hourly employee, gross pay starts with the hours worked in the pay period and the hourly rate. Multiply the regular hours worked by the regular hourly rate to get regular gross pay. Then add any overtime pay to get total gross pay for the period.

The hours come from a time tracking system, a timesheet, or a time clock that records each employee's worked time for the pay period. Review the hours for accuracy before payroll, including overtime, breaks, and time off. Accurate hours are the foundation of accurate gross pay for hourly staff, which is why collecting and reviewing hours before the cutoff matters so much.

How Overtime Fits Into Gross Pay

Overtime pay is part of gross pay. It is calculated using the overtime hours worked and the overtime rate, which is often a multiple of the regular hourly rate. For many employees, the overtime rate is one and a half times the regular rate for hours worked beyond the standard threshold in a workweek. The exact threshold and rate can depend on the employee, the work, and the rules that apply where the employee works.

To calculate total gross pay for an hourly employee with overtime, calculate regular pay first, then calculate overtime pay separately, and add the two together. Keeping the regular and overtime calculations separate is what keeps overtime accurate. For more on how the schedule that holds these hours comes together, see our guide on how to create a reliable payroll schedule.

How to Calculate Salaried Gross Pay

For a salaried employee, gross pay is the annual salary divided by the number of pay periods in a year. The number of pay periods depends on the pay schedule. A weekly schedule has 52 pay periods, a biweekly schedule has 26, a semimonthly schedule has 24, and a monthly schedule has 12. The annual salary split evenly across those periods gives the gross pay for each pay period.

Because the salary splits evenly, a salaried employee's gross pay stays the same each pay period, which makes it more predictable than hourly gross pay. The calculation is simpler, but the accuracy still matters. Confirm the annual salary and the pay schedule before the first pay run so the split is right from the start. For more on how the schedules compare, see our guide on weekly vs biweekly vs semimonthly payroll.

Example: An Hourly Employee's Gross Pay

Consider a small retail shop with an hourly employee paid $18 per hour on a weekly pay schedule. In a week where the employee works 40 regular hours, their regular gross pay is $720, which is 40 hours times $18. No overtime applies, so total gross pay for the week is $720 before withholdings.

In another week, the same employee works 44 hours, with 4 of those hours counted as overtime. Regular gross pay is still $720 for 40 regular hours. If the overtime rate is one and a half times the regular rate, the overtime rate is $27 per hour, and 4 overtime hours add $108 of overtime pay. Total gross pay for that week is $828. The example shows how keeping regular and overtime hours separate keeps gross pay accurate.

Example: A Salaried Employee's Gross Pay

Take a small consulting firm with a salaried employee paid $60,000 per year on a semimonthly pay schedule, which is 24 pay periods. Each pay period, the employee's gross pay is $2,500, which is the annual salary divided by 24. Because the employee is salaried, the owner does not collect hours each period, but still confirms the salary and pay schedule before each run.

If the same employee were paid biweekly, which is 26 pay periods, their gross pay would be about $2,308 per period instead. The annual salary stays the same, but the split across pay periods changes with the schedule. The example shows how the pay schedule shapes the gross pay number even when the annual salary does not change.

Common Gross Pay Calculation Mistakes

• Adding overtime hours to regular hours before multiplying. Overtime hours use the overtime rate, not the regular rate. Adding them to regular hours and multiplying by the regular rate underpays overtime. Keep the two calculations separate and add the results.
• Using the wrong number of pay periods for a salary. A biweekly schedule has 26 pay periods, not 24. Dividing an annual salary by the wrong number makes every paycheck wrong. Confirm the pay schedule and the pay period count before the first run.
• Collecting hours late or not reviewing them. For hourly staff, late or unreviewed hours mean late or wrong gross pay. Collect hours before the cutoff and review them for overtime, breaks, and time off.
• Confusing gross pay with net pay. Gross pay is before withholdings and deductions. Net pay is after. Using net pay where gross pay belongs understates the paycheck and throws off every line below it.
• Not confirming the pay rate or salary before the first run. A pay rate or salary entered incorrectly compounds over every paycheck until someone catches it. Double check each rate against the offer or agreement before you save it.

Getting Started

Calculating employee gross pay comes down to knowing the pay type, the pay rate, and the hours or salary that drive it. For hourly staff, multiply regular hours by the regular rate and add overtime pay. For salaried staff, divide the annual salary by the number of pay periods. When gross pay starts from the right number, the withholdings, deductions, and net pay that follow all calculate from a correct base.
