You can be slammed on Friday night and still end the week with no cash. That is the most common owner complaint right now, and it is usually a math problem, not a demand problem.

Quick Summary

  • U.S. food-away-from-home CPI was +4.0% year over year in the January 2026 release.
  • The Census/FRED food services sales series still showed large topline numbers, but month-to-month movement stayed choppy.
  • In the Fed Small Business Credit Survey, owners reported rising operating costs and uneven cash flow at the same time.
  • Fixes start with one weekly audit: sales, COGS, labor, channel fees, and fixed-cost run rate.

What the 2026 Data Says

Here is the pressure stack U.S. operators are dealing with:

  • BLS CPI (released February 13, 2026): food away from home +4.0% YoY, +0.1% month over month.
  • FRED / Census RSFSDP series: December 2025 was 100,229 (millions, seasonally adjusted), near November 2025 (100,374).
  • Fed Small Business Credit Survey (2025 report):
    • 56% cited rising costs of goods/services as a financial challenge.
    • 37% cited operating expenses.
    • 35% cited uneven cash flow.
    • 34% cited weaker sales.
    • 77% said operating expenses increased year over year.

Translation: many stores are carrying higher cost pressure even when tickets keep coming in.


Why “Busy” Still Feels Broke

Most leaks show up in one of these places:

  1. Low-margin items driving high volume
  2. Labor hours added to chase peaks that do not cover loaded labor cost
  3. Delivery/promo/payment fees treated as overhead, not item cost
  4. Waste, remakes, and discounting not tied back to menu pricing

If you only watch total sales, you miss all four.


15-Minute Sunday Margin Audit

Pull these five numbers every week:

LineWhat to pullWhy it matters
1Net sales (before sales tax)Your real denominator
2COGS (food + beverage + packaging)Variable cost pressure
3Labor (wages + employer on-costs)The other fast-moving cost block
4Channel fees (marketplace + payment + promo)Hidden margin leak
5Fixed-cost run rate (weekly)Cash survival threshold

Then run:

primeCostPercent = (COGS + Labor) / NetSales
afterChannelPercent = (NetSales - COGS - Labor - ChannelFees) / NetSales
cashResultBeforeFixed = NetSales - COGS - Labor - ChannelFees
cashResultAfterFixed = cashResultBeforeFixed - FixedCosts

Do this weekly, same day, same format.


One-Week Example

Assume this week:

  • Net sales: $24,500
  • COGS: $8,580
  • Labor: $8,960
  • Channel fees: $2,210
  • Fixed costs (weekly run rate): $5,100

Math:

  • Prime cost = ($8,580 + $8,960) / $24,500 = 71.6%
  • After-channel dollars = $24,500 - $8,580 - $8,960 - $2,210 = $4,750
  • After fixed costs = $4,750 - $5,100 = -$350

This store can feel busy every night and still lose cash every week.


7-Day Fixes When You See a Leak

  1. Reprice or redesign top-10 high-volume, low-contribution items first.
  2. Stop blanket discounts and keep only offers that lift ticket size.
  3. Separate dine-in, pickup, and marketplace margin tracking.
  4. Cap low-margin third-party promos until contribution improves.
  5. Tighten prep and pars on items with frequent waste/remakes.
  6. Rebuild staffing around half-hour demand windows, not averages.
  7. Recheck the same five lines next week and compare deltas.

What Owners Keep Saying in Community Threads

Across owner forums, the same pattern repeats:

  • “Sales are not dead, but bills keep catching up.”
  • “Overhead and payroll pressure make volume feel pointless.”
  • “Guests think owners are rich while operators report very thin margins.”

Use that as a signal to manage by contribution and cash, not by gross sales alone.

Frequently Asked Questions

Why can a restaurant be busy and still lose money?

Because sales volume alone does not guarantee margin. If food, labor, and channel fees rise faster than price, busy service can still produce weak cash flow.

What should I check first when profit disappears?

Check weekly net sales, COGS, labor, and channel fees on one sheet. Most operators find the problem in those four lines.

How often should I run a margin audit?

Weekly is best. Monthly is too slow when food, labor, and promo costs are moving.

Do I include sales tax in my denominator?

No. Use net sales before sales tax when calculating food cost, labor cost, and prime cost.

What is a quick warning sign?

If weekly cash is flat or falling while sales are stable, you likely have margin leakage by item, shift, or channel.

Can I fix this without a full menu reprint?

Usually yes. Start with item-level contribution checks, labor scheduling fixes, and channel-specific price rules.
