Calculate restaurant labor cost
Formula used
Target labor dollars = Net sales × Target labor %.
The optional labor-hours field calculates sales per labor hour. That productivity measure is useful only when the restaurant defines labor hours consistently and compares similar periods, dayparts, or operating conditions.
What the result can and cannot tell you
The calculator quantifies the gap. It cannot tell you whether the cause was weak sales, poor forecasting, overtime, training hours, call-outs, slow deployment, an unusually demanding event, or a manager decision that protected service. Review those causes before changing the schedule.
Use the same definitions each period
Keep labor cost and net sales definitions consistent. If one report includes payroll burden and another includes wages only, or one period uses gross sales while another uses net sales, the comparison will mislead the manager.
Turn the number into a controlled action
- Verify sales and labor inputs.
- Compare scheduled and actual hours by daypart.
- Find the largest dollar cause.
- Check guest service, quality, training, and workload effects.
- Assign and verify the smallest correction that addresses the cause.
