Pay components (includable in regular rate)
If salary covers all hours worked, OT premium is additional 0.5 × regular rate × OT hours. If it covers only 40 hours, check below.
Regular rate uses includable pay ÷ total hours. Nondiscretionary bonuses and commissions must be included. Service charges count as wages; tips do not.
Tipped settings
OT floor for tipped = 1.5 × minimum wage − tip credit. Calculator shows both regular‑rate method and tipped‑floor method.

Regular rate = (includable pay ÷ total hours worked).
OT premium (regular‑rate method) = 0.5 × regular rate × OT hours (assuming straight‑time already paid for all hours).
Tipped OT floor = 1.5 × minimum wage − tip credit. Employer must ensure wages + tips meet ≥ 1.5 × min wage on OT hours.
