Overtime pay calculator

Enter your hourly rate, regular hours, overtime hours and multiplier to see weekly gross pay broken into regular and overtime earnings.

How this calculator works

In the US, the Fair Labor Standards Act requires covered employers to pay non-exempt employees 1.5 times their regular rate for hours worked beyond 40 in a workweek. So a $20 hourly rate becomes an overtime rate of $30, and 10 overtime hours add $300 to the week's pay. Overtime is generally based on the regular rate, which can include non-discretionary bonuses and shift differentials — not just the base hourly wage.

The multiplier is editable because rules differ: some union agreements, public-sector contracts and holiday policies pay double time, and a few pay 1.25×. The calculation here is weekly gross pay before tax; it assumes the overtime hours are all paid at the chosen multiplier. State rules can differ from federal ones — California, for example, requires overtime after 8 hours in a day as well as over 40 in a week.

The formula

Regular pay = hourly rate × regular hours. Overtime pay = hourly rate × multiplier × overtime hours. Total gross pay is their sum:

At the federal US default of 1.5×, the overtime hourly rate is one and a half times the regular rate.

Worked example

At 20 an hour with 40 regular hours and 10 overtime hours at 1.50×, regular pay is $800.00, overtime pay is $300.00, and total gross pay is $1,100.00 for the week.

Common mistakes

• Only counting hours over 40 in a week. Some states and contracts require daily overtime. Check local rules before relying on the federal rule.
• Using the wrong base rate. Bonuses and shift differentials may increase the regular rate used for overtime, which raises the overtime pay.
• Forgetting tax on overtime. Overtime is taxed like ordinary income. A higher-gross week can push part of the pay into a higher marginal bracket.
