# Prime Cost: The One Number That Decides If Your Venue Survives (2026)

> Five widely cited restaurant guides put a healthy prime cost anywhere from 55% to 70% of sales, and none cites a study behind its number. Here is the segment-adjusted range, a five-line weekly tally you can run without an accountant, and which cost to fix first when it slips.

## Key takeaways

- Five widely cited restaurant-operations guides put a "healthy" prime cost anywhere between 55% and 70% of sales, and not one of them cites a study, survey, or dataset behind its number.
- A venue sitting comfortably at 60% prime cost can still lose money if rent, insurance, and loan payments add up to more than about 10% of sales: the two ratios have to be read together, not one at a time.
- Checking prime cost monthly means finding a cost overrun three to four weeks after it started; a five-line weekly tally from your POS, invoices, and rota catches it while you can still change next week's order or schedule.
- Chipotle's own 2024 portion audit found bowl weights on the same order type varying by up to 87% between locations, and the company chose to raise average portions again that October, deliberately pushing its food cost back up to fix it.
- useforcs.com's operator diagnostic treats food cost above roughly a third of sales as a goods problem and labour cost above a similar threshold as a scheduling problem, and recommends fixing labour first when both are elevated, because a schedule correction lands next week while a supplier or menu fix takes longer.

Prime cost is a simple idea with a fancy name: what you spend on food and drink, plus what you spend on your team, added together and shown as a share of what you take in. Most guides say a healthy number sits around **55-65% of sales**, a bit tighter if you run a quick counter, a bit looser if you run a sit-down restaurant. What they don't tell you: nobody has actually studied where that range comes from, the "right" number depends on your rent as much as your menu, and chasing it down the wrong way can cost you guests or staff faster than ignoring it ever would.

This picks up where two of our other guides leave off. [Pricing your menu](/blog/menu-pricing-calculator) covers the food side in detail, and [labour cost](/blog/restaurant-labour-cost-percentage) covers the wage side. Prime cost is just the two of them added together, asking one plain question: does the whole thing actually work?

## Five guides, five different numbers

**Search "prime cost percentage" and you will find five different target ranges, and none of the five sources shows its work.** Laid side by side, the spread looks less like measurement error and more like five different rules of thumb that happened to converge on the same rough neighbourhood.

| Source | Stated target | Cites a study? |
| --- | --- | --- |
| White-Hutchinson Leisure & Learning Group (2005) | 60% or less | No |
| TouchBistro | Under 60%, "55% is better" | No |
| 7shifts / Restaurant365 (consensus) | 55-65%, banded by segment | No |
| MarketMan | 55-65%, up to 68% for fine dining | No |
| useforcs.com | Unprofitable above roughly 70% | No |

Every one of these is a software company or a consultant sharing what they've seen, not a government body publishing hard numbers the way statistics offices do for other costs. That doesn't make the range worthless: five people landing in roughly the same place from real experience is worth something. But treat it as a rough guide, not a grade you pass or fail, and remember that what counts as "healthy" depends more on what kind of place you run than on the headline number.

## The band moves with what you serve

**A quick-service counter and a fine-dining room can both run a perfectly healthy prime cost while sitting more than ten points apart, because how many people they serve, and how much each person spends, are completely different games.** 7shifts and Restaurant365 land on close to the same numbers by segment, which is the more useful agreement to take from the mess above.

**Prime cost target by venue segment**

| Segment | Typical range | Source |
| --- | --- | --- |
| Quick service / counter | 55-60% | 7shifts, Restaurant365 |
| Fast casual | 58-63% | 7shifts, MarketMan |
| Full service | 60-65% | 7shifts, Restaurant365 |
| Fine dining | 60-68% | MarketMan (weakly corroborated) |

*Fine dining's upper bound appears in fewer independent sources than the other three rows and should be read as a softer ceiling. A bar or pub program is not listed because no source publishes a combined prime-cost figure for one; see the bar section below for why the split behaves differently even where the total lands in the same range.*

A fine-dining room can run a higher number because it serves fewer meals a night at a much higher price each: the same hour of a cook's time and the same plate of food earn more, even though they cost the same to produce. A bar tells a different story again. Spirits carry a huge markup, often four to six times what the bottle cost, while beer and wine make far less, so a bar usually reaches a healthy number through cheap drinks and a heavier staffing bill, not the food-driven mix a kitchen runs on. Two venues sitting at the exact same overall number can be solving completely different problems.

## Weekly, not monthly, and by hand if that's what you have

**Checking prime cost once a month means finding a problem three to four weeks after it started, by which point you have already over-ordered or over-scheduled for most of that time.** This isn't a new idea. Back in 2005, restaurant consultant White-Hutchinson was already telling owners to check labour cost daily and food cost at least every couple of weeks, for exactly this reason. What's changed since is that most advice written today assumes you're already running software to do it for you. One inventory company, MarketMan, admits the real problem outright: pulling the numbers by hand from your till, your payroll, and a stack of invoices "eats an afternoon nobody has." That's true, which is exactly why the version below doesn't need you to buy anything.

**Prime cost by hand, once a week**

1. **Pull net sales:** One number from your POS for the trading week, excluding tax. Keep the same seven-day window every time.
2. **Add up purchases:** Food and drink invoices received that week stand in for cost of goods sold. A monthly physical stock count corrects the drift this shortcut builds up.
3. **Add fully loaded labour:** Wages plus taxes, benefits, and any statutory on-costs for the same week, plus your own hours at what you would pay someone else to cover them.
4. **Add the two together:** Purchases plus fully loaded labour is your prime cost in currency. Divide by net sales and multiply by 100 for the percentage.
5. **Compare to your segment band:** Quick service around 55-60%, full service 60-65%. A single week above target is a data point, not a verdict.
6. **Diagnose before you cut:** Work out which half is actually elevated before changing a schedule or a menu. The next section walks through exactly that.

*Ten minutes once the habit is set. Purchases are an approximation of what was actually sold rather than sitting in the walk-in, which is the trade-off that makes a weekly number possible without a stock system; reconcile it against a real count monthly.*

## Which half to fix, and why it matters which one you pick

**A prime cost that is over target tells you nothing about which of its two halves is the actual problem, and cutting the wrong one wastes effort while risking the part that was fine.** One restaurant-costing site, useforcs.com, offers a simple way to split it up. If food cost alone is climbing past roughly a third of sales, that's a goods problem. If labour alone is climbing past a similar mark, that's a scheduling problem. If both are running hot at once, fix labour first: a schedule change shows up in next week's numbers, while a new supplier deal or a menu rework takes longer to land.

**Which half of prime cost is actually the problem?** *(interactive matrix in the web version)*

| Labour cost share | Goods cost share | Route | What to do |
| --- | --- | --- | --- |
| In range | In range | Protect it, don’t squeeze it | Both halves sit inside their usual band. Check pay rates and portion sizes before assuming this is clean margin rather than a quiet underpayment or quality problem; an unusually low ratio can mean either. |
| In range | Elevated | Fix the plate | Goods cost is the driver; labour is already lean. Check portioning, waste, and supplier pricing before touching a single shift. |
| Elevated | In range | Fix the schedule | Labour is the driver; goods cost already sits in range. Pull covers per labour hour by daypart before cutting food quality or portions. |
| Elevated | Elevated | Fix labour first | Both halves are elevated at the same time. Start with the schedule: it corrects faster than a supplier or menu change, and buys time to fix goods cost properly. |

*Thresholds follow useforcs.com's operator-level rule of thumb for a full-service structure; adjust the split for your own segment band from the table above.*

Here's what that looks like on real data instead of a hunch. One cocktail bar in Germany, an anonymised Super44 example, compared its till data against its rota, found that its last opening hour Tuesday through Thursday simply wasn't paying for itself, and closed earlier Tuesday through Thursday after a four-week trial with a roll-back plan built in. That's the "fix the schedule" box, in practice.

**Your prime cost, in your own currency** *(interactive calculator in the web version)*

Example (Weekly net sales: 6,000, Weekly cost of goods (purchases): 1,800, Weekly fully loaded labour cost: 2,100):

- Prime cost: 65.0 %
- Goods cost share: 30.0 %
- Labour cost share: 35.0 %

*Works in any currency because the result is a ratio. Enter your own weekly figures; the two share outputs tell you which half to check first against the diagnosis above.*

## The ratio is incomplete without your rent

**A venue can sit comfortably inside a healthy prime cost and still lose money every month if the cost of running its building eats too much of what's left over.** Armitage Accounting, a firm that works with restaurants, has a simple rule of thumb: keep everything to do with your space, rent, insurance, your share of the building's upkeep, at or under 10% of what you take in. Go much above that and cash flow gets tight no matter how good your food and labour numbers look. How much of that is "just rent" depends on your type of place: a quick counter can often get away with less, a sit-down restaurant a bit more, and fine dining can stretch furthest because it charges so much more per table.

Put the two together and it gets uncomfortable fast. A restaurant running a "fine" 65% prime cost, with its space costs at the high end too, has already spent three-quarters of every euro, pound, or dollar it takes in, before marketing, loan payments, or a single unit of profit even get a look-in. The same restaurant on a cheap, long-standing lease has real breathing room to run a slightly higher prime cost and still come out ahead. Neither number tells you the whole story on its own; you have to read them side by side.

## What over-optimising actually costs

**Chasing prime cost down by cutting portions, ingredient quality, or staffing without checking what it does to guests and the team is how a healthy-looking ratio turns into a shrinking business.** Two dated, sourced 2024 cases show both directions of that risk.

**What the Chipotle and Red Lobster cases actually show**

*Source: CBS News, Fox Business, and Reuters/inkl reporting, 2024*

- **Supported:** A Wells Fargo analysis weighed 75 Chipotle bowl orders (half digital, half in-person) across 8 New York locations in mid-2024 and found the heaviest bowl weighing up to 87% more than the smallest; Chipotle's CFO confirmed that October that the company deliberately raised average portions again, accepting higher food cost to fix the guest-facing problem. Separately, cost-cutting including sole-sourcing shrimp and understaffing that could not handle its own Endless Shrimp promotion contributed to Red Lobster's 2024 bankruptcy, with the promotion alone costing about $11m of a $73m net loss.
- **Not established:** Both are large multi-unit chains carrying private-equity ownership and promotional pressures a single independent venue does not have. The cases show that guests and analysts notice cuts and that a chain can choose to reverse one, not that any specific percentage point of prime cost is where damage begins for a smaller, owner-run business.

There's an upside to this too. A fine-dining room deliberately sits near the top of that range, because it serves fewer people a night but charges each of them a lot more, so the same plate and the same hour of a chef's time earn more money than they would in a busy counter-service shop running a much lower number. A higher prime cost is only a problem when it creeps up without a matching decision behind it: about price, about cooking from scratch, about the kind of service you're offering.

**Before you cut anything**

- [ ] **Check the guest, not just the number**: Would this change what a guest is served, how long they wait, or the plate they expected? If yes, price it against reviews and repeat visits, not just the ratio.
- [ ] **Check the team**: Does the cut push a shift below safe coverage, or move hours onto the people already there as unpaid overtime?
- [ ] **Check demand before rate**: A quiet daypart is usually a demand problem, not a wage problem; our guide to sales per labour hour and our overtime guide both cover how to tell the difference.
- [ ] **Check rent before ratio**: If occupancy cost already runs near or above 10% of sales, a small prime-cost win will not fix the underlying model on its own.

*Prime cost is a guardrail for a decision an owner still has to make, not a target that overrides safe staffing, food quality, or the kind of venue you set out to run.*

## Making versus buying moves the split, not the total

**A venue that bakes its own bread or butchers its own meat is trading labour cost for goods cost against one that buys the prepared version, and prime cost alone can't tell you which choice is right.** A steakhouse buying steaks already cut and portioned is choosing a simpler, pricier ingredient line over a smaller kitchen and fewer paid hours. One that butchers whole cuts itself is making the opposite trade. The only fair comparison is what it actually costs to buy the finished product, against everything it costs, ingredients and labour together, to make it yourself. As an example: a cafe baking its own pastries from scratch might end up with cheaper ingredients but a bigger wage bill, say 22% goods cost and 40% labour. A cafe buying in frozen dough and baking it off might flip that around: 34% goods cost and 28% labour. Add either pair up and you land on the same 62% prime cost. Neither is more "correct." It depends on the skills already on your team, how much kitchen space you can spare, and whether "baked here" is worth something to your customers that the frozen version isn't.

That's exactly why the weekly habit matters more than hitting a magic number. Check only the total, and you won't notice which side is actually moving from month to month. Check both halves every week, and you can tell a deliberate choice apart from a slow drift nobody meant to happen. Keeping the [labour](/blog/restaurant-labour-cost-percentage) and food halves split out, by time of day, alongside the combined number, is the version worth keeping, and it's exactly the kind of bookkeeping Super44 is built to take off your hands: connect your till and your rota, and it keeps your prime cost current, split into its two halves by time of day, with a specific action waiting wherever something has moved.

If the schedule side of that split is where your number lives, our guide to [sales per labour hour](/blog/splh-benchmarks) walks through the same weekly habit one daypart at a time, and our [overtime guide](/blog/overtime-root-cause) covers the five repeatable causes that inflate the labour half before you ever look at goods cost.

## FAQ

### What is a good prime cost percentage for a restaurant?

There is no single audited answer, and no source cites a study behind the number it quotes. The working consensus across restaurant-operations platforms runs 55-65% of net sales, tightening to about 55-60% for quick service, 58-63% for fast casual, and loosening to 60-65% for full service and sometimes higher for fine dining. Treat the range as a starting band for your segment, not a pass/fail line, and read it alongside your occupancy cost before deciding anything is "good."

### How do I calculate prime cost by hand every week without an accountant?

Pull net sales for the week from your POS, add up that week's food and drink purchases as a stand-in for cost of goods sold, add fully loaded labour cost (wages plus taxes and benefits, plus your own hours at a replacement wage if you work shifts), then divide the sum by net sales. It takes five lines on a notepad and about ten minutes once you have the habit, and a monthly stock count corrects any drift the purchases-only shortcut introduces.

### Should I cut labour or food cost first when prime cost is too high?

Check which half is actually elevated before cutting either. If goods cost alone is high, look at portioning, waste, and supplier pricing before touching a schedule. If labour alone is high, pull covers per labour hour by daypart before cutting food quality. If both are high at once, fix labour first, because a schedule change shows up in next week's numbers, while a supplier or menu fix takes longer to land.

### Does a good prime cost percentage guarantee my restaurant is profitable?

No. Prime cost only covers two cost lines. A venue at a comfortable 60% can still fail if rent, insurance, utilities, and loan payments push total occupancy cost above roughly 10% of sales, and a venue with unusually cheap rent has more room to run prime cost a few points hotter and still clear a profit. Check the two together before concluding either one is fine on its own.

### Can a restaurant deliberately run a higher prime cost?

Yes, as a strategic choice tied to format rather than a warning sign. Fine dining sits at the top of the published segment bands (60-68%) by design, because a lower cover count and a higher average check mean the same labour hour and the same plate cost more relative to revenue while still producing more profit per table. The number only becomes a problem when it rises without a matching decision about price, quality, or service behind it.

### Is buying prepared food always cheaper than making it in-house?

Not on the prime cost line. It usually just moves the cost from labour to goods rather than removing it. A venue that bakes its own bread carries higher labour and lower food cost than one buying par-baked loaves, which carries the opposite split. Compare the landed cost of the bought-in version against the fully loaded cost of making it yourself, including the labour, before assuming either direction saves money.
