Overtime guide
Separate overtime math from overtime eligibility
A calculator can apply a multiplier. It cannot decide which law, exemption, workweek, or rate applies to a particular worker.
The arithmetic
Regular gross = base hourly rate × regular hours
Overtime gross = base hourly rate × overtime multiplier × overtime hours
Total gross = regular gross + overtime gross
At $24/hour, 40 regular hours are $960. Five hours at a 1.5× multiplier add $180, producing $1,140 gross for that example week. Multiplying $24 by all 45 hours would produce $1,080 and miss the $60 premium.
Inputs people commonly get wrong
- The workweek. Overtime may be evaluated by a defined workweek, not by averaging two weeks together.
- The regular rate. Certain non-discretionary payments may affect a legally defined regular rate; a headline base rate is not always the complete answer.
- Eligibility. Salary status alone does not establish whether overtime rules apply.
- State rules. State or local requirements may differ from a federal baseline.
- Gross versus net. The result is before withholding, benefits, garnishments, and other deductions.
Federal US context
The Fair Labor Standards Act provides a federal baseline for many covered, nonexempt employees, commonly described as overtime after 40 hours in a workweek at not less than one and one-half times the regular rate. Exemptions and definitions matter. Read theUS Department of Labor overtime fact sheetand applicable state guidance for an actual employment question. This page is educational, not legal advice.
Build a defensible estimate
- Record regular and overtime hours separately from a real schedule.
- Use the multiplier supplied by the applicable policy or authoritative guidance.
- Keep bonuses, differentials, commissions, and reimbursements separate unless you know how payroll treats them.
- Compare the estimate with the gross lines on a pay stub—not the final deposit.
- Ask payroll or a qualified professional about classification or legal eligibility.
Try those inputs in the paycheck scenario planner, then download the comparison with its assumptions.
