How Hourly Payroll Calculation Works
Calculating your hourly paycheck involves more than just multiplying your rate by your hours. To get an accurate estimate of your take-home pay, you must account for overtime premiums, statutory tax withholdings, and voluntary deductions.
The Gross Pay Formula
Gross pay is the total amount earned before any taxes or deductions are removed. The standard formula is:
(Regular Hours × Hourly Rate) + (Overtime Hours × Hourly Rate × Overtime Multiplier) = Gross Pay
In most jurisdictions, overtime begins after 40 hours worked in a single workweek, typically paid at 1.5 times the base hourly rate.
Understanding Withholdings and Deductions
Your net pay (or "take-home pay") is what remains after two main categories are subtracted:
Taxes: This includes Federal Income Tax, Social Security (6.2%), Medicare (1.45%), and potentially State and Local taxes.Deductions: These are often voluntary amounts for health insurance premiums, 401(k) contributions, or union dues.
Example Calculation
If you earn $20 per hour and work 45 hours in a week with a 20% total tax rate and $50 in health insurance deductions:
Regular Pay: 40 hours × $20 = $800
Overtime Pay: 5 hours × ($20 × 1.5) = $150
Gross Pay: $950
Tax Amount: $950 × 0.20 = $190
Net Pay: $950 – $190 – $50 = $710
