The formula
Overtime pay = Base hourly rate x Overtime multiplier x Overtime hours
Overtime premium = Base hourly rate x (Multiplier – 1) x Overtime hours
The first formula gives you the payroll number. The second gives you the management number. Those hours would have been worked anyway at straight time; the premium is the only part that buys nothing extra: no extra covers, no extra prep, no extra sales. That is why this calculator annualises it. A small weekly premium looks very different multiplied by 52.
Premium with burden = Premium x (1 + Payroll burden %), because employer taxes and insurance are charged on the full overtime rate.
Overtime share = Overtime pay / Total gross pay x 100, the quickest way to tell routine cover from a short-built schedule.
How to use it, with an example
- Take one full workweek. Overtime is a weekly rule, so a two week pay period hides it.
- Enter the base rate. If your team works at several rates, use the average of the people who work the overtime.
- Add the regular and overtime hours for that same week, from your time clock or payroll report.
- Set the multiplier your state or contract requires, and your payroll burden from your payroll provider.
- Read the premium per year first. That is the number to compare against one more part-time hire.
Worked example: Eight kitchen staff work 320 regular hours in a week at a blended $18 an hour, plus 12 overtime hours at time and a half, with a 12% payroll burden. The overtime rate is $27, overtime pay is $324, and total gross pay is $5,760 + $324 = $6,084. The premium inside that pay is 12 x $18 x 0.5 = $108 a week, $120.96 with burden added. Over a year the premium is $6,289.92, for hours straight-time cover would have handled. Overtime is 5.3% of gross pay, just inside the warning zone. The calculator above is prefilled with these numbers.
Overtime creeps up because scheduling, time clocks and payroll usually live in three different places, so nobody sees the premium until the period closes. Odoo for Restaurants puts roster, hours and payroll cost in one flow, and the Odoo HR module holds attendance and leave, so a manager sees who is nearing 40 hours before the shift is worked, not after it is paid.
Common mistakes
- Reading overtime pay as the cost. At time and a half, only a third of the overtime cheque is premium. Judge the schedule on the premium per year, not the payroll line.
- Leaving out the payroll burden. Employer taxes and workers comp are calculated on the overtime rate. At a 12% burden, every $100 of premium is really $112.
- Averaging hours across a two week pay period. Overtime is calculated workweek by workweek. A 50 hour week followed by a 30 hour week is still 10 overtime hours. Some states are stricter: California counts daily overtime too.
- Using the tipped cash wage as the base rate. For tipped staff, overtime is calculated on the full regular rate before the tip credit, not on the reduced cash wage. Using the cash wage understates the rate and the premium.
- Letting the same two people absorb every extra hour. Concentrated overtime turns a manageable premium into a resignation, and replacing a burned-out cook costs more than a season of premiums. Our guide to restaurant POS system cost covers the same budget from the technology side.
- Treating chronic overtime as a staffing fact. If overtime shows up in quiet weeks too, the base roster is short. Compare the annual premium with the cost of a part-time hire before accepting it as normal.
FAQs
When does overtime legally start for restaurant staff?
Under the US Fair Labor Standards Act, covered hourly staff earn overtime past 40 hours in a single workweek, at no less than 1.5 times their regular rate. Some states add daily overtime rules, and salaried staff are exempt only if they pass both a salary and a duties test.
Is the overtime premium the same as overtime pay?
No. Overtime pay is the full amount for those hours at the multiplied rate. The premium is just the extra slice above straight time: at time and a half, the 0.5 part. It is the true added cost of running past 40 hours, because the straight-time part would be paid to whoever worked the shift.
How much overtime is normal for a restaurant?
As a share of gross pay, under 5% is routine cover for holidays, sickness and events. Between 5 and 10% is a warning zone. Above 10% week after week points to an understaffed base schedule.
Does overtime cost more than hiring another person?
Often, yes, past a certain point. Compare the annual premium here with the straight-time cost of the same hours from a part-time hire. Once the premium approaches that cost plus recruiting and training, the extra hire is usually cheaper, and far easier on the team.
Do payroll taxes apply to overtime pay?
Yes. Employer payroll taxes, unemployment insurance and workers compensation are all calculated on gross wages including the overtime rate. That is the burden percentage in this calculator.
Can salaried managers be owed overtime?
Yes, if they are not genuinely exempt. Titles do not decide it; pay level and actual duties do. A salaried shift lead who spends most of the week cooking or serving may be non-exempt and owed overtime, one of the most expensive surprises in payroll audits.
