Formula
Weekly Pay = (Regular Hours × Rate) + (Overtime Hours × Rate × OT Multiplier)How to Calculate Work Hours and Overtime Pay
Understanding your exact earnings — including overtime — is essential for budgeting and negotiating compensation. This calculator breaks down your pay into regular hours, overtime hours, and total earnings on a weekly, monthly, and annual basis. Simply enter your daily hours, workdays per week, hourly rate, and overtime multiplier to see the full picture.
The standard overtime threshold in the United States is 40 hours per week. Any hours worked beyond 40 must be compensated at a minimum of 1.5 times your regular hourly rate (commonly called "time and a half"). Some employers offer double-time (2×) for holidays or excessive hours.
Regular vs. Overtime Hours Explained
If you work 8 hours a day, 5 days a week, you log exactly 40 regular hours with zero overtime. But bump that to 9 hours a day and you're at 45 hours — meaning 40 regular hours plus 5 overtime hours. Those 5 extra hours at 1.5× your rate can add up significantly over the course of a year.
For example, at $25/hour, those 5 weekly overtime hours earn you an extra $187.50 per week — that's $9,750 more per year compared to working a standard 40-hour week. Overtime can be a powerful income booster when managed properly.
Monthly and Annual Estimates
This calculator uses 4.333 weeks per month (52 weeks ÷ 12 months) for monthly estimates and 52 weeks for annual projections. These are useful for budgeting, but keep in mind that actual pay varies with holidays, vacation days, and sick time. Most full-time workers average about 50 actual working weeks per year after time off.
If you receive paid time off, your annual estimate from this calculator should be accurate. If your time off is unpaid, subtract those weeks from the annual figure for a more realistic number.
Maximizing Your Earnings
If you're an hourly worker looking to increase income, overtime is one of the most straightforward paths. Ten hours of weekly overtime at $25/hour with 1.5× pay adds $19,500 to your annual income. However, balance is important — sustained excessive overtime leads to burnout and decreased productivity. Many workers find that 5-10 hours of weekly overtime is the sweet spot between extra income and quality of life.
Frequently Asked Questions
When does overtime kick in?
Under the federal Fair Labor Standards Act (FLSA), overtime begins after 40 hours in a workweek. Some states like California also require overtime after 8 hours in a single day. Overtime must be paid at a minimum of 1.5× your regular rate.
How do I calculate my effective hourly rate with overtime?
Divide your total weekly pay by total hours worked. For example, if you work 50 hours at $25/hr with 1.5× overtime: (40 × $25) + (10 × $37.50) = $1,375 ÷ 50 hours = $27.50 effective rate.
Are salaried employees eligible for overtime?
It depends on your salary level and job duties. As of 2024, salaried employees earning less than $43,888/year are generally eligible for overtime. Certain executive, administrative, and professional roles are exempt regardless of salary.
How many work hours are in a year?
A standard full-time work year is 2,080 hours (40 hours × 52 weeks). After subtracting typical paid holidays (10 days) and vacation (10-15 days), actual working hours are roughly 1,920-1,960 hours per year.
What's double-time overtime?
Double-time (2× rate) is required in some states (like California) for hours worked beyond 12 in a single day or beyond 8 hours on the 7th consecutive work day. Federal law only requires 1.5× overtime and does not mandate double-time pay.
