Most all-you-can-eat restaurants charge $20–$30 per guest, serve 120–300 guests daily (up to 900 on peaks), and land around 45–55% gross margin and 5–15% net margin when costs are controlled. Profit swings are driven by food cost discipline, waste reduction, labor scheduling, and seat turns.
Use the table below to benchmark a “mid-range” operation using a $25 average check and 180 guests per day, then adjust for your city, concept, and scale.
| Metric | Typical Range | Notes for all-you-can-eat restaurants |
|---|---|---|
| Daily customer volume | 120–300 (up to 900 peak) | Higher on weekends/holidays; tourist and prime urban sites run hotter. |
| Average check (USD) | $20–$30 | Lunch skews lower; dinner and premium protein bars push upper range. |
| Food cost | 30–45% of revenue | $6–$13.50 per guest at $20–$30 pricing; tight menu engineering reduces variance. |
| Labor cost | 20–30% of revenue | Self-service lowers FOH labor; prep and dish are still significant. |
| Fixed overhead | $15k–$40k / month | Rent, utilities, insurance, licenses, equipment service; location-sensitive. |
| Gross margin | 45–55% | Revenue minus cost of food and disposables; excludes labor and overhead. |
| Net margin | 5–15% | After all overhead and marketing; chains trend higher via scale purchasing. |
What is the average daily customer volume and the typical price per guest (USD)?
Most all-you-can-eat restaurants serve 120–300 guests per day at $20–$30 per guest in the U.S.
Units in prime malls or tourism corridors can exceed 500 covers on heavy weekends and spike to 900+ on holidays. Lunch tends to land toward $20–$24, while dinner and premium protein concepts trend $26–$30.
A practical planning midpoint is 180 guests/day at a $25 average check, which suits mid-traffic suburban locations. Adjust your baseline by daypart mix, local income levels, and competitive density.
These inputs set your revenue ceiling and drive staffing, prep, and waste exposure.
Anchor your first-year model on realistic weekday counts; let weekends be the upside.
How much revenue does that generate per day, per week, per month, and per year—and how does season or location change it?
Revenue scales directly with covers and the average check; season and location can move results ±30–50%.
Using a $25 check and cover ranges commonly seen in all-you-can-eat restaurants, the table shows base-case and scenario revenue. Tourist hubs, downtown sites, and holiday periods push the top end; shoulder seasons pull down the bottom.
| Timeframe | Base case (180 covers @ $25) | Scenario notes (location & seasonality effects) |
|---|---|---|
| Per day | $4,500 | 120 covers = $3,000; 300 covers = $7,500; peaks up to 900 covers = $22,500 on rare holidays. |
| Per week | $31,500 | Weekend lifts of +20–50%; rainy off-season dips of −15–25% in tourist markets. |
| Per 4-week month | $126,000 | Typical range $90,000–$225,000 across low/high cover bands. |
| Per 12-month year | $1.512M | Broad range $1.08M–$2.7M; high-traffic chains can exceed $3M. |
| Urban premium | +10–25% | Higher rents offset some gains; beverage mix and party size often improve. |
| Tourist seasonality | ±30–50% | School holidays, festivals, and tour contracts drive sharp peaks. |
| Event days | +20–50% day-of | Sports, concerts, and conventions expand early/late shoulder demand. |
What are average food costs per guest (percent and dollars), and how are they tracked?
Food cost usually sits between 30% and 45% of revenue in an all-you-can-eat restaurant.
At a $25 check, that equals about $7.50–$11.25 per guest, with tighter menus and guided portioning keeping you near the 30–35% band. Operators track “theoretical food cost” from recipes and item yields, then compare to “actual” by counting inventory weekly and logging waste.
Daily line checks, prep lists, and batch sheets tie purchases to plates and reveal variance fast. A basic dashboard should show food cost %, cost/guest, variance to theoretical, and top five items driving slippage.
Do this from day one to catch creeping costs before they compress margin.
You’ll find detailed market benchmarks and tracking templates in our all-you-can-eat restaurant business plan.
How does food waste impact food cost, and how is it typically measured in this model?
Food waste is a margin killer in all-you-can-eat restaurants because plate waste and over-production compound losses.
Industry studies show buffets experience the highest plate-waste share, so a mid-size unit can see $400–$600 per day in waste if unmanaged. Most teams weigh waste by category (prep trim, over-production, plate returns), log it by station and daypart, and escalate items above a set threshold for recipe or signage changes.
Smaller plates, controlled tongs/ladles, and strategic item placement reduce over-portioning without hurting guest satisfaction. Rotating production in smaller batches stabilizes freshness and limits throw-outs late in service.
Track waste daily and review weekly—treat it like a controllable “bill” you pay unless you intervene.
We cover this exact topic in the all-you-can-eat restaurant business plan.
What are typical labor costs for chefs, servers, and cleaning staff (USD/day, week, month, year)?
All-you-can-eat restaurants usually run labor at 20–30% of revenue due to self-service FOH and steady BOH prep/dish needs.
The table shows common pay bands and rolled-up totals for a mid-size operation. Adjust for your local wage laws, hours, and staffing model.
| Role | Typical U.S. compensation | Daily / Monthly / Yearly cost illustration |
|---|---|---|
| Head Chef / Kitchen Manager | $45k–$75k per year | ~$180–$300/day; ~$5.4k–$9k/month; $45k–$75k/year (salary plus taxes/benefits). |
| Sous Chef | $38k–$55k per year | ~$150–$220/day; ~$4.5k–$6.6k/month; $38k–$55k/year. |
| Line Cook | $25k–$35k per year | ~$100–$140/day; ~$3k–$4.2k/month; $25k–$35k/year. |
| Prep Cook | $24k–$32k per year | ~$95–$125/day; ~$2.9k–$3.8k/month; $24k–$32k/year. |
| Server / Runner | $20k–$30k per year (mix of wage/tips) | ~$80–$120/day; ~$2.4k–$3.6k/month; $20k–$30k/year. |
| Busser / Dishwasher | $15k–$22k per year | ~$60–$90/day; ~$1.8k–$2.7k/month; $15k–$22k/year. |
| Cleaner (closing shift) | $14–$20 per hour | ~$70–$120/day (5–6 hrs); ~$2.1k–$3.6k/month; $25k–$35k/year if FT equivalent. |
How much do fixed costs (rent, utilities, equipment, licenses, insurance) contribute to the cost structure?
Fixed overhead typically ranges from $15,000 to $40,000 per month for an all-you-can-eat restaurant, depending on size and location.
Rent is the largest driver and can run $10,000–$25,000 per month in busier corridors; utilities ($3,000–$8,000), equipment service and licenses ($2,000–$5,000), and insurance ($400–$1,700) fill in the rest.
| Fixed cost category | Typical monthly USD | Operational notes |
|---|---|---|
| Rent / Common Area | $10,000–$25,000 | Prime trade areas cost more but can support higher covers and checks. |
| Utilities (power, gas, water) | $3,000–$8,000 | Buffets have sustained hot holding; off-peak scheduling reduces demand. |
| Insurance | $400–$1,700 | Liability and property; adjust for hood, fryers, alcohol service. |
| Licenses & Permits | $300–$800 | Health, food handler, fire safety; renewals often annual or biannual. |
| Equipment maintenance | $1,500–$4,000 | Steam tables, refrigeration, dish machine—preventive service is crucial. |
| Smallwares & replacements | $400–$1,200 | Utensils, pans, chafers, bulbs, signage wear-and-tear. |
| Waste & linen services | $300–$1,000 | Frequency rises with covers; negotiation lowers unit costs. |
What are marketing and promotion costs as a % of revenue and in dollars?
All-you-can-eat restaurants usually allocate 2–5% of revenue to marketing.
At $4,500/day revenue, that is $90–$225/day, $2,700–$6,750/month, and $32,400–$81,000/year. Spend tilts toward paid social, local maps/SEO, group sales, and partnerships with hotels and tour operators.
Track CAC (cost per acquired customer), retention, and group contract yields so you can reweight channels to the best ROI. Use bounce-back offers tied to quieter weekdays to smooth demand.
This is one of the strategies explained in our all-you-can-eat restaurant business plan.
Consistent local visibility and group deals are dependable volume levers.
How does scale (single unit vs. a chain) change unit costs, volume, and margin?
Scale improves purchasing power, marketing efficiency, and overhead absorption in all-you-can-eat restaurants.
Chains negotiate lower landed costs on proteins and disposables, centralize menu engineering, and spread corporate costs over more sales; this often nudges net margin from 5–10% toward 10–15%. Multi-unit marketing lowers CAC and stabilizes volume with loyalty and cross-promotions.
Central kitchens and standardized batch production reduce variance and waste, but require logistics discipline. Shared management benches also cut turnover costs and training time per unit.
If you plan to scale, lock spec sheets and recipes early so every unit runs the same “theoretical cost” model.

What is a typical gross margin %, and what does that mean in dollars?
Gross margin for all-you-can-eat restaurants typically lands between 45% and 55%.
At a $25 check and a 30–35% food cost, gross margin dollars equal $11.25–$13.75 per guest before labor and overhead. With 180 guests/day, that is ~$2,025–$2,475/day in gross profit contribution.
A higher beverage mix and tight waste control will keep you near the top of the range. Protein-heavy menus without portion cues compress gross margin fast.
Track gross margin weekly with a rolling 4-week view to catch drift promptly.
It’s a key part of what we outline in the all-you-can-eat restaurant business plan.
What do net profit margins look like after all overhead, and how much profit remains per guest and per timeframe?
After labor, overhead, and marketing, net margin for all-you-can-eat restaurants commonly falls between 5% and 15%.
Using the same $25 check and 180 covers/day, the table shows net profit in steady-state plus lean and peak scenarios. The spread depends on location rent, waste discipline, and beverage attachment.
| Timeframe / Scenario | Net margin | Net profit dollars (illustrative) |
|---|---|---|
| Per guest (steady) | 10% | ~$2.50 per guest at a $25 check. |
| Per day (steady) | 10% | $4,500 × 10% = ~$450 per day. |
| Per week (steady) | 10% | $31,500 × 10% = ~$3,150 per week. |
| Per month (steady) | 10% | $126,000 × 10% = ~$12,600 per month. |
| Per year (steady) | 10% | $1.512M × 10% = ~$151,200 per year. |
| Lean scenario | 5% | Gross profit squeezed by high rent or waste; ~$75k/year at base volumes. |
| Peak scenario | 15% | Well-run chains or prime sites; ~$225k+/year at base volumes. |
Which tactics and best practices reliably improve margins in this industry?
- Lead with filling, low-cost items (starches, salads) and place high-cost proteins later in the line to guide portions.
- Use smaller plates and measured utensils to curb over-serving without harming perceived value.
- Batch cook in smaller rounds and tighten par levels by daypart to reduce over-production and end-of-service waste.
- Engineer menu pricing around contribution margin, not just cost %, and highlight high-margin add-ons and beverages.
- Track waste by station daily and review the top five loss items weekly; change recipes, signage, or position.
- Schedule labor to the forecast by 30-minute increments; cross-train to flex up/down without overtime.
- Negotiate bulk purchasing and consolidate SKUs to unlock lower landed costs and fewer stockouts.
How do margins break down across buffet products and services, and how do changes here affect profits?
In all-you-can-eat restaurants, carbs, salads, and many desserts deliver high margin, while meats and seafood are lower margin and require portion guidance.
Shifting mix even a few points toward high-margin beverages and desserts can add $0.50–$1.00 per guest in net, which compounds across high volumes. Conversely, expanding premium protein choices without a price move or portion strategy will erode both gross and net margin.
Group packages, private rooms, and alcohol service materially lift contribution dollars if priced for staffing and cleaning time. Protect peak times for higher-spend parties and move discounts to shoulder periods.
Re-engineer the line to spotlight profitable items and nudge guests naturally toward them.
This is one of the many elements we break down in the all-you-can-eat restaurant business plan.
