How Overtime Pay Works in the US
The Fair Labor Standards Act (FLSA) requires that non-exempt employees receive overtime pay at a rate of at least 1.5 times their regular hourly rate for all hours worked beyond 40 in a single work week. This is commonly called "time and a half."
Formula: Overtime Pay = Overtime Hours x (Hourly Rate x 1.5)
Example Calculation
If you earn $20 per hour and work 45 hours in a week: Your regular pay is 40 hours x $20 = $800. Your overtime pay is 5 hours x $30 (1.5 x $20) = $150. Your total gross pay is $800 + $150 = $950.
FLSA Rules and Exemptions
- Non-exempt hourly employees are entitled to overtime after 40 hours per week.
- Some salaried employees classified as "exempt" (executive, administrative, professional) may not qualify for overtime.
- The FLSA does not require overtime pay for weekends, holidays, or nights unless those hours push the total past 40.
- State laws may provide additional protections beyond the federal FLSA minimum.
- Certain industries (healthcare, transportation, agriculture) have special overtime rules.
Important Notes
- This calculator provides estimates based on standard FLSA rules. Always verify with your employer or a labor law professional.
- Some states require daily overtime (over 8 hours in a day) or double time for certain conditions.
- This calculator uses a standard 40-hour work week threshold for overtime.
Frequently Asked Questions
Before you start, here's how to get the most out of this FLSA overtime calculator. It follows the federal rule: time and a half (1.5x) for every hour worked beyond 40 in a single work week. Enter your gross hourly rate — the rate before taxes or deductions — and the total hours you actually worked, including partial hours (the calculator accepts quarter-hour steps). It then splits your week into 40 regular hours and any overtime hours, showing regular pay, overtime pay, and combined gross pay. Three tips for accurate results: use one full work week, not a month or a pay period; include every hour worked, even if your employer rounds time; and remember the result is gross pay — federal and state taxes, Social Security, and Medicare are withheld later. If you earn tips, commissions, or a salary, or if your state uses daily overtime (like California's eight-hour threshold), treat the result as an estimate rather than a final payroll figure. When in doubt, confirm with your employer or state labor department.
How do I use the overtime calculator to find my time and a half pay?
Enter your hourly rate and the total hours you worked in one week, then hit calculate. The tool applies the FLSA 40-hour threshold: the first 40 hours are paid at your regular rate, and every hour beyond that is paid at 1.5 times your rate. For example, at $20 an hour with 45 hours worked, you get 40 hours at $20 ($800) plus 5 hours at $30 ($150), for $950 in gross pay. Use the same week your employer uses for payroll, and include partial hours — the calculator accepts quarter-hour steps.
How accurate is this overtime calculator compared to payroll software?
For a standard hourly, non-exempt employee, the math is exact: it applies the same 1.5x multiplier and 40-hour work week that payroll systems use, down to the cent. It will match a payroll run when your inputs are right — the correct gross hourly rate and the precise hours worked. The difference is scope, not accuracy: payroll software also handles state-specific rules, shift differentials, tips, bonuses, and deductions. If you work in a state with daily overtime or your pay includes non-hourly income, treat the result as a close estimate and verify against your pay stub or payroll department.
What are the limits of this FLSA overtime calculator?
The calculator is designed for one scenario: hourly, non-exempt employees on a standard 40-hour federal work week. It does not cover salaried exempt workers, piece-rate or tipped employees, or state rules like daily overtime beyond eight hours or double-time pay. It also does not subtract taxes — the result is gross pay before federal and state withholding. Hours are capped at 168 per week and hourly rates at $9,999.99, matching realistic payroll ranges. Use it to double-check a paycheck or plan a budget, but for disputes, audits, or multi-state payroll, consult your employer or a labor-law professional.
Does this calculator update when FLSA overtime rules change?
The tool is built around the core federal overtime rule — time and a half after 40 hours in a work week — which has been the standard under the FLSA for decades and rarely changes. What does change are the salary thresholds for exempt employees and state-level rules; when those shift, the site is updated to reflect them. Since the calculator focuses on the basic 1.5x rule, day-to-day changes rarely affect its output. Still, if you rely on it for budgeting or pay disputes, periodically confirm current thresholds with the U.S. Department of Labor.
How is this free calculator different from overtime pay apps and other calculators?
Most overtime calculators and payroll apps either sit behind sign-ups, push premium plans, or bury the 1.5x rule under dozens of options. This one is free, with no account, no ads, no download, and one focused purpose: applying the federal time-and-a-half rule to your hours in seconds. Unlike general payroll tools, it shows the math step by step (regular pay, overtime pay, total) so you can see how the number is built and check it against your pay stub. It won't replace full payroll software, but for a fast, trustworthy estimate it's all you need.
