How to Calculate Overtime Pay

Overtime pay is straightforward: identify hours over the threshold, then multiply by your overtime rate. Here is the step-by-step process.

1

Total your hours

Add up all hours worked during the pay period. Include every shift, partial hour, and any work performed outside normal hours.

2

Identify overtime hours

Subtract the overtime threshold (typically 40 hours/week under FLSA) from your total. The remainder is your overtime hours. If total is under the threshold, you have zero overtime.

3

Apply the overtime rate

Multiply overtime hours by your hourly rate times the OT multiplier. For time-and-a-half (1.5x), a $25/hr worker earns $37.50/hr for each overtime hour.

4

Calculate total gross pay

Add regular pay (regular hours times hourly rate) plus overtime pay. For 45 hours at $25/hr with 1.5x OT: $1,000 regular + $187.50 overtime = $1,187.50 total.

Frequently Asked Questions

Subtract the overtime threshold (usually 40 hours/week) from your total hours worked. Multiply the overtime hours by your hourly rate times the overtime multiplier (1.5x for time-and-a-half). Add that to your regular pay (regular hours times hourly rate) to get total gross pay.

Time and a half means paying 1.5 times the regular hourly rate for overtime hours. If your regular rate is $20/hour, time-and-a-half pays $30/hour for each overtime hour. This is the federal minimum overtime rate under the Fair Labor Standards Act (FLSA).

Double time pays 2x the regular hourly rate. Federal law does not require double time, but some states (like California) mandate it for hours worked beyond 12 in a single day, or for the first 8 hours on the seventh consecutive workday.

Under federal FLSA rules, overtime begins after 40 hours in a workweek for non-exempt employees. Some states have lower thresholds: California requires overtime after 8 hours in a single day, and Colorado requires it after 12 hours in a day or 40 in a week.

It depends on exempt vs non-exempt status. Non-exempt salaried employees earning below the FLSA salary threshold ($58,656/year as of 2025) are entitled to overtime. Exempt employees (executive, administrative, professional) generally are not.

California has daily overtime rules in addition to weekly. Employees earn 1.5x after 8 hours in a day (not just after 40/week), and 2x after 12 hours in a day. California also requires 1.5x for the first 8 hours on the 7th consecutive workday.

Federal FLSA calculates overtime weekly (over 40 hours per workweek). However, Alaska, California, Colorado, and Nevada have daily overtime thresholds. Check your state laws -- this calculator uses the weekly method by default.

Yes. Automatic time tracking software like Rize records your hours in the background and shows exactly when you cross the overtime threshold. You get accurate overtime calculations without manual timecards, reducing payroll errors and compliance risk.

FLSA overtime rules explained

The Fair Labor Standards Act requires employers to pay non-exempt employees at least 1.5 times their regular rate for hours worked over 40 in a workweek. A workweek is any fixed, recurring 168-hour period. Employers cannot average hours across multiple weeks unless they qualify for a specific exemption (like the 8/80 rule for healthcare workers).

Penalties for FLSA overtime violations include back pay for up to three years, liquidated damages equal to the back pay amount, and civil penalties up to $2,074 per violation. Accurate time records are the employer's responsibility under federal law.

State-by-state overtime differences

While federal law uses a 40-hour weekly threshold, several states have stricter rules. California requires 1.5x after 8 hours in a day and 2x after 12 hours. Colorado mandates overtime after 12 hours in a day or 40 in a week. Alaska requires overtime after 8 hours per day for employers with 4+ employees.

When state and federal overtime rules conflict, the rule more favorable to the employee applies. This calculator defaults to the 40-hour federal threshold -- adjust the threshold field for your state's daily rules.

Overtime calculator vs automatic time tracking

This calculator works for quick estimates, but manual hour entry introduces error. The American Payroll Association estimates that manual time tracking has an error rate of 1-8%, costing employers 2.2% of gross payroll annually in overpayments and disputes.

Automatic time tracking software eliminates this by recording work sessions as they happen. Rize tracks your hours in the background and alerts you when you approach the overtime threshold, so you can make informed decisions about overtime before it becomes a payroll surprise.
