How overtime pay is calculated

Regular hours are paid at your normal rate; overtime hours are paid at your rate times the multiplier:

Gross = (regular hours × rate) + (overtime hours × rate × multiplier)

Example. You work 45 hours at $20/hour. The first 40 hours are regular ($800). The 5 overtime hours are paid at 1.5× = $30/hour, so $150. Your gross pay is $950 for the week.

Frequently asked questions

How do I calculate overtime pay?

Overtime is usually paid at 1.5 times your regular hourly rate for hours worked over 40 in a week. Multiply your rate by 1.5 to get the overtime rate, then multiply by your overtime hours. Example: $20/hour becomes $30/hour overtime; 5 overtime hours = $150.

What is time and a half?

Time and a half means 1.5 times your regular hourly rate. If you earn $20 an hour, time and a half is $30 an hour. It is the standard federal overtime rate in the US under the Fair Labor Standards Act (FLSA).

How much is $20 an hour time and a half?

$20 an hour at time and a half is $30 an hour. For 45 hours in a week (40 regular + 5 overtime), you would earn $800 regular + $150 overtime = $950 gross.

When does overtime start — 40 hours or 8 hours a day?

Under federal FLSA rules, overtime applies after 40 hours in a week. Some states (like California) also require daily overtime after 8 hours a day. Set the threshold in the calculator to match your rule.

Is double time the same as overtime?

No. Overtime is typically 1.5×, while double time is 2× your regular rate, often for holidays or hours beyond a daily limit in certain states. Change the multiplier to 2 to calculate double time.

Is overtime pay before or after tax?

This calculator shows gross overtime pay before tax. Overtime earnings are taxed as regular income; your take-home amount will be lower after withholding.
