Labor is your biggest controllable expense, and most operators are flying blind when it comes to measuring whether their staffing decisions are actually paying off. Sales per labor hour (SPLH) fixes that—it’s a simple formula that tells you how much revenue your restaurant generates for every hour of labor you pay for.
SPLH won’t solve all your problems, but it gives you a clear number to track and improve. This guide covers the formula, realistic benchmarks by restaurant type, and how to use SPLH to build smarter schedules and tighter labor budgets.

What is sales per labor hour (SPLH)?
Sales per labor hour (SPLH) tells you how much revenue your restaurant generates for every hour of labor you pay for. You calculate it by dividing total sales by total labor hours worked during a specific period. If your Saturday dinner brought in $5,000 and your team worked a combined 50 hours, your SPLH for that shift is $100.
SPLH is a productivity metric, not a cost metric. It measures how efficiently your team converts labor into revenue, but it doesn’t tell you what you’re paying per hour. A $100 SPLH looks different when your average wage is $12 versus $18.
Think of SPLH like a speedometer. It tells you how fast you’re going, but not how much gas you’re burning.
Why SPLH matters for restaurant profitability
Labor is typically your largest controllable expense. Most restaurants spend somewhere between 25% and 35% of revenue on labor, and small shifts in productivity can mean thousands of dollars over a month.
SPLH gives you a way to measure whether your staffing decisions are paying off:
- Overstaffing: If your SPLH drops during certain shifts, you might have too many people on the floor for the volume you’re doing.
- Understaffing: A spike in SPLH sounds good on paper, but it often means your team is stretched thin and service quality suffers.
- Shift comparisons: You can compare your Tuesday lunch to your Saturday dinner and see which dayparts are most productive.
- Location benchmarking: For multi-unit operators, SPLH lets you compare performance across locations with different sales volumes.
The real power of SPLH is in the patterns. One slow Tuesday doesn’t mean much. But if your Tuesday lunch SPLH has been declining for six weeks, that’s a signal worth investigating.
The sales per labor hour formula
The formula is straightforward:
Total Sales ÷ Total Labor Hours = SPLH
A few notes on the inputs. “Total sales” refers to net sales (after discounts and comps), not gross sales. “Labor hours” include all paid hours during the period you’re measuring, including servers, cooks, hosts, bussers, and managers if they’re on the clock.
You can calculate SPLH for a single shift, a full day, a week, or any period that makes sense for your operation. The key is consistency. Compare apples to apples.
SPLH calculation example for a full-service restaurant
Your Saturday dinner shift runs from 4 PM to 11 PM. You have three servers (each working 7 hours), two line cooks (7 hours each), one prep cook (4 hours), one dishwasher (7 hours), one host (6 hours), and one manager (7 hours).
Total labor hours: 21 + 14 + 4 + 7 + 6 + 7 = 59 hours
Your POS shows $5,900 in net sales for that shift.
SPLH = $5,900 ÷ 59 = $100 per labor hour
SPLH calculation example for a quick-service restaurant
Your lunch rush runs from 11 AM to 2 PM. You have four team members working the full three hours, plus one manager.
Total labor hours: 15 hours
Net sales: $2,250
SPLH = $2,250 ÷ 15 = $150 per labor hour
The formula is identical. The difference is in what you’re measuring and what targets make sense for your concept.
What is a good sales per labor hour for restaurants?
There’s no universal “good” SPLH. A $75 SPLH might be excellent for a fine dining restaurant with high labor intensity, while the same number could signal trouble for a fast-casual concept.
Your target depends on your restaurant type, service model, location, and wage rates. The most useful approach is to establish your own baseline and improve from there.
| Restaurant Type | Reasonable SPLH Range | Why It Differs |
|---|---|---|
| Full-service | $50–$80 | More servers per guest, longer table times, complex service |
| Fast-casual | $80–$120 | Counter service with some table touches, moderate labor needs |
| Quick-service | $100–$150+ | Fast transactions, simpler execution, fewer labor hours per customer |
Keep in mind that ranges vary based on your market, menu prices, and operating model.
Full-service restaurant SPLH benchmarks
Full-service restaurants typically run lower SPLH numbers because the service model demands more labor per guest. You’ve got servers, bussers, food runners, hosts, bartenders, and a full kitchen crew, all working longer guest visits.
Fine dining runs even lower because of the attention each table requires. A casual dining spot with faster turns will see higher SPLH than a white-tablecloth restaurant with two-hour seatings.
Quick-service restaurant SPLH benchmarks
Quick-service restaurants see higher SPLH because transactions are faster and labor requirements per customer are lower. A drive-thru can process dozens of orders per hour with a small crew.
That said, QSR margins are often tighter, so hitting your SPLH targets matters even more. The difference between $140 and $150 SPLH across a week adds up fast.
Fast-casual restaurant SPLH benchmarks
Fast-casual sits in the middle. You’ve got counter service (faster than full-service) but often more food prep and sometimes table touches. Expect SPLH somewhere between full-service and quick-service, depending on how much labor your concept requires.
How to track SPLH in your restaurant
Tracking SPLH requires two data points: sales and labor hours. The question is how you pull them together.
Manual SPLH tracking
The spreadsheet approach works, but it takes time. You pull sales data from your POS at the end of each shift or day, then pull hours from your time tracking system or schedule. Plug both into a spreadsheet, run the calculation, and you’ve got your SPLH.
The downside? It’s manual, it’s after the fact, and it’s easy to make mistakes. By the time you realize your Tuesday lunch SPLH was off, Tuesday is long gone.
Automated SPLH tracking with scheduling software
Restaurant scheduling software that connects to your POS can calculate SPLH automatically. You see labor costs and productivity metrics in real-time as you build your schedule, not days later when you’re reconciling spreadsheets.
Tools like 7shifts pull sales data directly from your POS and match it against scheduled (or clocked) hours. You can see projected SPLH before the shift even starts, then compare it to actual results afterward.

How to use SPLH for scheduling and labor budgets
Knowing your SPLH is only useful if you act on it. Here’s how to put the number to work.
Set target SPLH goals by daypart
Your lunch SPLH target will differ from your dinner target. A slow Monday will look different from a busy Saturday.
Look at your historical data, ideally several weeks’ worth, and set realistic targets for each daypart. Once you have targets, you can build schedules that hit them. If your Saturday dinner target is $95 SPLH and you’re projecting $6,000 in sales, you know you can afford roughly 63 labor hours for that shift.
Create labor budgets based on sales forecasts
Work backward from your projected sales. If you’re forecasting $8,000 for a Friday and your target SPLH is $90, you’ve got a budget of about 89 labor hours for the day. Divide that across your shifts and positions.
This approach keeps your labor spending tied to expected revenue, not just “what we did last week.”
Make real-time staffing adjustments
SPLH isn’t just for planning. Use it during shifts to make decisions.
If sales are running 20% below forecast by 6 PM, you might send someone home early. If you’re getting slammed and SPLH is spiking, it might be worth calling in backup. The goal is to stay flexible. Schedules are a starting point, not a contract.
How to improve your SPLH
There are two levers: increase sales or reduce labor hours. Both have tradeoffs, and the right approach depends on your situation.
Increase sales per shift
More revenue with the same labor hours means higher SPLH. A few ways to get there:
- Train servers on upselling appetizers, desserts, and premium drinks. Small additions per table add up across a shift.
- Adjust your menu layout to highlight higher-margin items where eyes naturally land.
- Run promotions during slow dayparts. A Tuesday happy hour that brings in 20 extra covers improves your SPLH without adding labor.
Reduce labor hours without cutting service quality
This isn’t about cutting hours across the board. It’s about scheduling smarter.
- Cross-train employees: A server who can run food or a cook who can prep means you need fewer specialists on each shift.
- Stagger start times: Not everyone needs to arrive at 4 PM. Bring people in as volume builds.
- Review historical patterns: If your Wednesday dinner never hits projections, adjust the schedule before you’re overstaffed again.
Tip: Pull your last four weeks of sales by daypart before building next week’s schedule. Patterns emerge fast, and you’ll spot where you’ve been consistently over- or under-staffed.
SPLH limitations and when to use other metrics
SPLH is useful, but it doesn’t tell the whole story.
- It ignores wage rates: A $100 SPLH means different things if your average wage is $14 versus $20.
- It doesn’t measure service quality: A sky-high SPLH might mean your team is drowning and guests are waiting too long.
- It can mask problems: A combined SPLH for your whole restaurant might hide that your kitchen is overstaffed while your floor is stretched thin.
Use SPLH alongside other restaurant metrics:
- Labor cost percentage: Shows actual dollars spent on labor as a share of sales.
- Covers per labor hour: Tracks throughput regardless of check size, useful when menu prices vary.
- Sales per server: Helps identify your top performers and where training might help.
Take control of your restaurant labor costs
SPLH gives you a clear, simple way to measure labor productivity. Calculate your current SPLH this week, by shift, by day, by location, and use it as a baseline. Then start making small adjustments to your schedule and see what moves the needle.

FAQs about sales per labor hour
What is the difference between SPLH and labor cost percentage?
SPLH measures productivity, or how much revenue you generate per hour worked. Labor cost percentage measures expense, or what portion of your sales goes to paying staff. An SPLH of $100 tells you about efficiency. A labor cost of 30% tells you about spending. Both are useful, but they answer different questions.
How often should restaurants calculate SPLH?
Weekly is the minimum for spotting trends. Daily or by-shift gives you more actionable data for adjusting schedules in real-time. The more frequently you track, the faster you can respond to problems.
Should restaurants calculate SPLH separately for front of house and back of house?
Yes. Separating FOH and BOH SPLH helps you pinpoint where productivity issues actually exist. A combined number might look fine while your kitchen is overstaffed and your floor is understaffed, or vice versa.
What is the 30 30 30 rule for restaurants?
The 30 30 30 rule is a general guideline suggesting restaurants aim for roughly 30% on food costs, 30% on labor costs, and 30% on other operating expenses, with the remaining 10% as profit. It’s a starting point, not a hard rule. Your actual targets will depend on your concept and market.
Does the SPLH calculation include tips?
No. SPLH uses net sales revenue only. Tips don’t flow through your sales figures and aren’t part of your labor cost equation, so they’re excluded from the calculation.
