Shift Staffing Calculator
How do I staff Friday without over-scheduling or getting buried?
Staff to the covers you expect and the section size you can actually serve, then check the labour cost that schedule implies before you post it.

The answer
Servers needed
8
240 covers at 32 per server
- Support staff4
- Total labour hours84 hrs
- Scheduled labour cost$1,148.00
- Covers per server at this schedule30
- Exact requirement before roundingRounded up to whole people. A fraction just below a whole number is where a shorter shift or a mid-shift start helps.7.5
- Forecast sales$9,120
- Implied labour costFront of house only, before payroll burden and before kitchen labour.12.6%
- Sales per labour hour$108.57
This staffs the shift as a whole. It does not solve a 7pm rush inside a slow night. That needs staggered starts, not more bodies for the full shift.
Labour cost, % of sales
Operator survey- Full-service restaurant (median, all respondents)36.5%
- Full-service, profitable operators (median)34.2%
- Full-service, operators reporting a loss (median)42.9%
- Limited-service restaurant (median, all respondents)31.7%
- Limited-service, profitable operators (median)30%
Reported by operators to an industry association and published as a median.
This figure includes salaries, wages, and benefits. The gap between profitable and unprofitable operators — 34.2% against 42.9% — is the most useful line here.

03 Show the arithmetic
Servers = forecast covers ÷ covers per server, rounded up
Support staff = servers × support ratio, rounded up
Labour cost = (servers × shift hours × server rate) + (support × shift hours × support rate)
Implied labour % = labour cost ÷ (forecast covers × average check) × 100
04 What the answer leaves out
- Front of house only. Kitchen labour, payroll burden, and salaried management are not included, so the real labour percentage is higher.
- Servers in tip-credit states are often paid a lower cash wage. Use the cash wage you actually pay, and remember the tip credit does not reduce your payroll tax base.
