Prime Cost Recovery Playbook: 80% to 65% in 90 Days

Bottom line: Prime cost above 75 percent of sales means the store cannot pay rent, overhead, and owner draw. The 90 day fix is three moves in order: cut waste and theft, tighten scheduling to sales, and reprice the top-selling items by 3 to 5 percent. Done right, an 80 percent prime cost drops to 65 percent inside a quarter.

Bottom line: A prime cost above 75% is a going-out-of-business number. Getting it back into the mid-60s in a quarter takes weekly discipline on menu prices, portion sizes, schedule tightening, and inventory variance. Here is the 90-day sequence.

Moving a restaurant from an 80% prime cost (the two biggest lines you buy every month: food and labor) (the sum of your food, beverage, and labor costs, expressed as a percent of sales) to a healthy 65% takes 90 days, three levers, and weekly measurement. The three levers are pricing, portion control, and labor scheduled to forecast. Ten to twelve points come from pricing and portion inside 30 days, four to six from labor by day 60, and the last two to three from vendor renegotiation by day 90.

Prime cost is food and beverage cost plus total labor cost, divided by sales. 65% is the ceiling for full-service and the working target for fast casual. Below that, occupancy and other operating expenses have room to breathe. Above 70%, there is no profit left to run the business. Every point of prime cost is roughly a point of net margin.

Most independent restaurants sit between 74% and 82% before they get intentional about it. If you have not measured yours in the last 30 days, that is where the work starts. For the underlying formula, see our primer on prime cost as the survival metric.

Week 1 and 2: diagnose the leak

You cannot cut what you have not measured. In the first two weeks, build the daily and weekly view.

Daily numbers to track: sales, food cost dollars, labor cost dollars, comp dollars.

Weekly numbers to track: prime cost percentage by daypart, sales per labor hour by shift, the top ten items sold with their theoretical vs actual food cost, and inventory turns.

Restaurants stuck at 80% prime cost almost always have one of three specific leaks. First, overbuying against soft sales, which shows up as a high walk-in and freezer value relative to weekly cost of goods. Second, overscheduling because the manager guesses instead of forecasts, which shows up as sales per labor hour well below the concept target. Third, a menu with three or four items that carry 45%+ food cost and sell in high volume. Find the leak before spending energy on levers that will not move the number.

Week 3 and 4: recipe recosting

Every item on the menu needs a current recipe cost card. Not last quarter’s. This week’s. Beef, dairy, seafood, and produce prices move fast enough that a card from 90 days ago is wrong on at least a third of the menu.

Sort the menu by food cost percentage, then by contribution margin (sales price minus the variable cost to make it) (sales minus variable costs, before fixed costs like rent). You will find three groups.

Group A: high volume, high cost percentage. These are the ones killing you. Reprice, resize, or reformulate. A center-of-the-plate protein moved by an ounce is 6% to 8% of that item’s food cost. Repricing a burger from $16 to $17 on a menu that sells 400 burgers a week is $52,000 a year in incremental gross margin (sales minus cost of goods, as a percent of sales) (sales minus cost of goods sold, before labor and everything else) at a 30% food cost.

Group B: high volume, healthy margin. Leave alone. Feature them, upsell them, promote them.

Group C: low volume, high cost percentage. Cut them. They tie up prep labor and inventory for no revenue benefit. Read our menu engineering guide for the full framework.

The typical result of an honest recosting exercise is a 1.5 to 2.5 percentage point drop in food cost over the following month.

Week 5 and 6: portion control and prep discipline

Recipes are numbers on paper. Portion control is what happens on the line.

Buy scales. Weigh proteins, weigh cheese, weigh sauce. Every station gets a portion chart taped up. A cook who scoops 5.2 ounces instead of the specified 4 ounces has just given away 30% of that item’s contribution margin. Multiply by 200 covers a night, and you understand why the P&L keeps disappointing.

Prep discipline matters as much as portion. Overprep is waste. Underprep sends cooks scrambling and buying emergency inventory at retail prices from the market next door. Build par sheets from the last four weeks of sales, not from what feels right. Reset pars every 30 days.

The gain from portion and prep discipline alone is another 1 to 2 points of food cost. See how to lower food cost in a restaurant for the tactical detail.

Week 7 and 8: labor scheduled to sales per labor hour

Labor is the biggest lever most operators refuse to touch. They schedule from habit, not from data.

Sales per labor hour, or SPLH, is total sales divided by total labor hours worked in a shift. Every concept has a target. Fast casual $80 to $110. Casual full service $70 to $95. Fine dining $100 to $150. Anything below target means the shift was overstaffed. Anything above target and consistent means understaffed and guest experience is at risk.

The exercise is straightforward. Pull a month of shifts, calculate SPLH for each. Then rebuild the schedule with the target in mind. Cut the two weakest shifts by an hour each. Move the strongest cook to the busiest four hours of the busiest day instead of the whole shift. Push the opener 30 minutes later on the days that historically start slow.

The average operator finds 4 to 6 percentage points of labor without cutting a single position. See our sales per labor hour deep-dive for the calculation and benchmarks by concept.

Week 9 and 10: third-party delivery renegotiation

DoorDash, Uber Eats, and Grubhub take 15% to 30% off the top. If delivery is 20% of your sales and you are paying 25%, that is 5% of total sales evaporating before food cost even shows up. Adjusted prime cost including delivery fees is often 3 to 4 points worse than the P&L suggests.

Three moves.

One. Raise delivery menu prices 15% to 20%. Guests do not comparison shop across platforms and your food cost as a percentage of the higher menu price drops meaningfully.

Two. Renegotiate the commission. Any restaurant doing $10,000 or more per month through a platform has use. Ask for 18% or walk. Half the time they blink. The account executive would rather cut their take than lose the volume.

Three. Build first-party ordering. A branded online order channel through Toast, Square, or Olo captures the same order at 3% instead of 25%. Every order you move off DoorDash is worth 20 to 25 cents on the dollar.

Week 11 and 12: waste, comps, and staff meals

The last 90 basis points of prime cost hide in the small stuff.

Waste: log it. Every walk-in check, every dumpster load. What gets logged, gets fixed. A dedicated waste sheet at the pass and one in prep, filled out end of shift, will surface 1% of sales in avoidable loss within two weeks.

Comps: managers hand them out because it is easier than saying no. Cap comp authority at 2% of shift sales. Anything above that requires the general manager. Track comp dollars weekly on the same scorecard as sales.

Staff meals: track them. A restaurant with 25 employees eating one meal per shift at cost is giving away roughly $60,000 a year if not accounted for. See staff meals and food cost impact.

The scorecard that keeps it stuck

The gain is easy to lose if the weekly scorecard goes away. Every Monday morning, the GM and the operator look at one page. Prior week prime cost. Sales per labor hour by shift. Top three variance items on food cost. Comp dollars. Waste log dollars. Twenty minutes. Non-negotiable.

Restaurants that keep the scorecard hold the 65%. Restaurants that stop looking drift back to 72% within a quarter. For the full scorecard, see the 12 restaurant KPIs to track weekly.

Cash and inventory tie-up: the hidden win

Cutting prime cost from 80% to 65% is a P&L win. It is also a cash flow win most operators miss. Lower food cost usually means tighter pars, which means less cash sitting in the walk-in. A restaurant doing $150,000 a month in sales with a 30% food cost carries roughly $45,000 in monthly food purchases. Trimming inventory turns from 2.0 to 3.0 frees up $15,000 in working capital. That is real money that stops being locked in produce and protein you have not sold yet.

Combine tighter inventory with the labor discipline in weeks 7 and 8, and payroll cash outflow drops in step with the P&L number. Two payroll cycles in, you have real cash sitting in the operating account instead of a paper margin that never showed up. If cash is tight, run the labor rebuild first and the delivery renegotiation second.

FAQ

Is 65% prime cost realistic for a full-service restaurant?
Yes for casual and upscale casual. Fine dining with heavy protein and low labor use may land at 66% to 68%. Fast casual should be under 60%.

What if my labor is already at the SPLH target?
Then the levers are food cost, delivery mix, and waste. Skip weeks 7 and 8 and double the time on the other levers.

Can software do this instead of a manager?
No. Software surfaces variance. A human decides which shift to cut, which item to reprice, and which supplier to switch. Buy the software after the discipline is in place, not before.

How often should I recost recipes?
Every 60 days minimum, every 30 days if beef, seafood, or dairy are more than 25% of your cost of goods sold.

What is a fast-food or QSR target?
Prime cost 55% to 60%. The labor use of counter service and lower per-hour rates makes it achievable.

Frequently Asked Questions

How do you get prime cost from 80% down to 65%?

Three levers in sequence: reprice against real food cost by day 15, retrain kitchen on portion control by day 30, then rebuild the labor schedule against a rolling four-week forecast. Track weekly.

How long does prime cost recovery take?

A disciplined 90 days for the full move from 80% to 65%. Pricing lifts show in 15 days, portion in 30, labor in 60, vendor negotiation in 90.

What is the biggest lever?

Menu pricing. Most 80% prime cost operators are underpriced on their top five sellers by 8% to 15% and have not moved prices in 18 months.

Should I cut staff first?

No. Cutting hours before fixing pricing and portion means the same margin problem with worse service. Fix pricing and portion first, then rebuild the schedule.
