About this calculator
Enter the overtime multiplier used for this estimate. Pay rules depend on jurisdiction, worker classification and the applicable agreement; this is not a legal determination and does not estimate payroll taxes or deductions.
Worked example
calculated with the default values below
Regular hourly rate 25 $ · Regular hours 40 h · Overtime hours 5 h · Overtime multiplier 1.5 x Total pay 1,187.50 $ · Regular pay 1,000.00 $ · Overtime pay 187.50 $ · Overtime hourly rate 37.50 $
Method and assumptions
T = r×H + r×m×h Regular pay = hourly rate × regular hours. Overtime = hourly rate × user-entered multiplier × overtime hours. Combined hours above 168 per week are rejected; applicable legal eligibility and tax treatment vary by jurisdiction. Enter the overtime multiplier used for this estimate.

Regular pay = hourly rate × regular hours. Overtime = hourly rate × user-entered multiplier × overtime hours. Combined hours above 168 per week are rejected; applicable legal eligibility and tax treatment vary by jurisdiction.
Frequently asked questions
Can the calculator use more than 168 total hours in a week?
No. Regular and overtime hours combined cannot exceed 168 hours in a week. The entered overtime multiplier is only a scenario input; local law, exemptions, and employment agreements determine actual eligibility and pay.
Why can I set the overtime multiplier above the usual one and a half?
The default multiplier is 1.5, the common legal rate, but the field accepts 1 to 3 so you can model double time or a union rate. At $25 an hour, 5 overtime hours at 1.5 pays $187.50 on top of $1,000 regular pay, a $37.50 hourly overtime rate. Raising the multiplier to 2 lifts that overtime portion to $250 without touching regular earnings.
