2.4 Cost Control & Budgeting
Key Takeaways
- Monthly food cost = beginning inventory + purchases - ending inventory; this is the cost of food actually consumed during the period, not just what was purchased.
- Food cost percentage = monthly food cost divided by sales, times 100; a rising percentage signals waste, over-portioning, theft, or pricing problems (CBDM example: $12,356 / $36,421 = 33.9%).
- Raw food cost per patient day (PPD) = monthly food cost divided by total patient days, where total patient days = number of patients times days in the month.
- An operating budget covers recurring day-to-day costs (food, labor, supplies); a capital budget covers major long-term purchases such as a new oven or walk-in cooler and is approved separately.
- Most healthcare dietary departments are noncommercial cost centers measured on cost per patient day and budget variance rather than profit, while commercial operations are judged on profit and loss.
The CDM as Financial Manager
The CBDM describes the CDM, CFPP as the financial and budgeting expert of the dietary department. After labor, food is the largest cost, so cost control directly protects the facility's bottom line. Expect calculation questions on the exam.
Monthly Food Cost (Cost of Food Consumed)
Do not confuse purchases with what was actually used. The cost of food consumed in a period is:
Monthly food cost = Beginning inventory + Purchases - Ending inventory
CBDM example: $21,745 (beginning) + $7,976 (purchases) - $17,365 (ending) = $12,356. The beginning and ending figures come from your physical inventory counts.
Food Cost Percentage
Food cost percentage is the share of revenue spent on food and is the central cost-control metric:
Food cost % = (Monthly food cost / Sales) x 100
CBDM example: $12,356 / $36,421 = 33.9%. A rising percentage warns of waste, over-portioning, theft, spoilage, or pricing problems - investigate before it erodes the budget.
Cost Per Day Metrics
In healthcare, costs are normalized to patients served:
| Metric | Formula |
|---|---|
| Raw food cost per patient day (PPD) | Monthly food cost / total patient days |
| Total cost per patient day | (Monthly food cost + labor costs) / total patient days |
| Raw food cost per meal | Monthly food cost / total meals served |
Note: total patient days = number of patients x days in the month (e.g., 95 patients x 30 days = 2,850 patient days). With $12,356 food cost, PPD = $12,356 / 2,850 = $4.33.
Labor Cost
Labor is the largest expense in most operations. Labor cost percentage = (labor cost / sales) x 100. Staffing is often measured in full-time equivalents (FTEs), where one FTE is about 2,080 paid hours per year. Control labor with accurate scheduling, productivity standards, and forecasting.
Budgets and Cost Types
- Operating budget - recurring day-to-day costs: food, labor, disposables, small supplies
- Capital budget - major long-term purchases (new oven, walk-in cooler), approved separately
- Fixed costs stay the same regardless of volume (rent, salaried staff); variable costs rise and fall with meals served (food, hourly labor, disposables)
Cost-Control Techniques
Standardized recipes, portion control, FIFO rotation, accurate forecasting to limit overproduction, competitive bids and specifications, and waste tracking all hold costs down.
Profit/Loss vs Noncommercial Cost Centers
- Commercial operations (restaurants, catering) are judged on profit and loss - revenue must exceed cost
- Noncommercial healthcare dietary departments are usually cost centers: success is measured by cost per patient day and budget variance, not profit, while still meeting nutrition and quality standards
A dietary department starts the month with $18,000 in inventory, purchases $9,000 of food, and ends with $15,000 in inventory. What is the monthly food cost (cost of food consumed)?
Monthly food cost is $13,000 and total food sales for the month are $40,000. What is the food cost percentage?
A skilled nursing facility had a monthly food cost of $12,000 with an average of 100 residents over a 30-day month. What is the raw food cost per patient day (PPD)?
Which purchase should be planned through the capital budget rather than the operating budget?
