What Is Effective Hourly Revenue — And Why It Predicts Your Margins Better Than Labor %

If you run a restaurant, you already watch labor percentage. It's on every P&L, every weekly flash report, every conversation with your accountant. It's the number you defend when the month is tight.
It's also the number most likely to lie to you.
Labor % isn't wrong. It's just slow, and it hides the thing you actually need to see: whether the hours you're paying for are producing revenue. There's a better number for that. It's called Effective Hourly Revenue, and once you start watching it, labor % feels like reading yesterday's weather.
Why labor % lies to you
Labor percentage is labor cost divided by sales. Two moving parts. When the number gets worse, you can't tell which part moved.
Say your labor runs 30% on a busy Friday and 41% on a slow Tuesday — same crew size, same wages. Nothing about your scheduling was "worse" on Tuesday. Sales just dropped. The ratio punished you for a demand problem and called it a labor problem.
It works the other way too. Run a deep discount, pack the room, and your labor % drops. Looks like a win. But you may have sold more food at a worse margin and just buried it under a healthier-looking ratio.
That's the trap. Labor % blends labor productivity and sales volume into one number, then asks you to manage both with one lever.
Takeaway: If labor % moved this week, you still don't know why. That's the problem.
What Effective Hourly Revenue actually measures
Effective Hourly Revenue (EHR) is simple: total revenue divided by total labor hours worked.
If you did $6,400 in sales on a shift and your team worked 80 labor hours, your EHR is $80. Every hour on the clock generated $80 of revenue. Some operators call this sales per labor hour. Same idea.
The reason it's more useful: it isolates productivity. It doesn't care how your ratio looks. It tells you what each scheduled hour produced. A dead hour with three people standing around shows up immediately — it drags EHR down whether or not your labor % looks fine for the day.
You're no longer managing a blended ratio. You're looking straight at the thing you control: how many people you put on the floor, and when.
Takeaway: EHR answers one question labor % can't — is this hour worth staffing?
Why it predicts your margins
Prime cost — food plus labor — is where restaurants live or die. Labor % tells you where prime cost landed. EHR tells you where it's heading.
Here's why. When EHR is healthy, you're scheduling to demand: people on the floor when revenue is there, fewer people when it isn't. That discipline flows straight into prime cost. When EHR sags in specific dayparts, you've found margin leaking before it ever shows up on the monthly P&L.
Labor % is a rearview mirror. EHR is the windshield. By the time a bad labor % hits your statement, the money's already gone. EHR shows you the soft daypart this week, while you can still fix the schedule.
Takeaway: Watch EHR by daypart and you catch margin problems weeks before your P&L does.
How to start tracking it this week
You don't need new software. You need two numbers you already have.
- Pull sales by daypart from your POS — open-to-2pm, 2pm-5pm, 5pm-close. Most systems do this in two clicks.
- Pull actual labor hours for those same windows from your scheduling tool or timeclock.
- Divide. Sales divided by hours equals EHR for each daypart.
Do it for one week. You'll almost certainly find one window — for a lot of DFW operators it's that 2pm-to-5pm dead zone — where EHR falls off a cliff. That's not a mystery anymore. That's a scheduling decision, or a revenue decision, and now you can see it.
Takeaway: One week of daypart EHR will show you exactly where you're overstaffed.
The dead-hour problem catering quietly solves
Here's what makes EHR click for restaurant operators.
That soft afternoon window kills your average. Your kitchen is staffed, your prep crew is in, and revenue is thin. EHR for those hours might be half your dinner number.
Catering revenue lands in exactly those hours. A $900 catering order gets produced during prep time you're already paying for. It doesn't add labor hours — it adds revenue to hours that were already on the clock. That's the fastest way to lift EHR in your worst daypart without touching the schedule.
Which is the real reason catering matters more than most operators treat it. It's not a side hustle. It's margin repair for the part of your day that's bleeding. The catch is you have to actually catch the catering leads coming at you — and most kitchens are quietly dropping them. That's a separate post, and it's the one I'd read next.
Takeaway: Catering revenue lifts EHR most where you need it most — the dead hours you're already paying for.
Start watching the right number
Keep your labor % report. Your accountant wants it and the bank wants it. Just stop using it to make scheduling decisions.
Run EHR by daypart for two weeks. Find your worst window. Fix it — with a smarter schedule, a revenue play, or catering filling the gap. Then watch your prime cost follow.
Labor % tells you what already happened. Effective Hourly Revenue tells you what to do about it.
