Estimate the direct cost of discarded food by multiplying the number of discarded portions by the cost per portion. This simple estimate excludes other costs and does not determine whether food is safe to serve.
Estimate total training hours by multiplying the number of food handlers by the hours assigned to each person. This planning estimate assumes every trainee receives the same amount of training.
Multiply the number of packages in a production batch by the units in each package to estimate the total number of individual units to label. This quantity estimate does not determine what information a food label must legally contain.
Calculate the percentage of weight lost between a food sample’s starting and ending weights. The result is a weight-loss measure and does not identify how much of that change was moisture.
Convert a cooking temperature between Celsius and Fahrenheit. Enter the temperature and choose its source scale to see the equivalent temperature on the other scale.
Estimate the amount of food on hand after a planned period of storage, using your starting quantity, daily use, and storage days. This is a simple inventory worksheet and does not determine whether food remains safe to eat.
Estimate the food cost assigned to a batch for thawing by multiplying its weight by the cost per kilogram. This is a simple ingredient-value estimate and does not include labor, energy, packaging, or spoilage.
Estimate the combined volume of items in a freezer inventory by multiplying the number of containers by the volume of each container. Enter container volume in liters.
Convert a freezer temperature between Celsius and Fahrenheit. Enter the measured temperature and choose its unit to see the equivalent reading.
Convert a refrigerator temperature between Celsius and Fahrenheit using the standard temperature conversion formulas.
Estimate the total heating time for a batch of leftover portions by multiplying the number of portions by the average minutes needed per portion. This simple estimate assumes each portion takes the same amount of time and does not assess whether food has reached a safe internal temperature.
Estimate the liquor cost per serving and pour cost percentage from a bottle's purchase cost, usable volume, serving size, and menu price. Assumes the bottle is fully usable and each serving is poured at the entered size.
Estimate the value of meat by multiplying its weight by its price per kilogram. This calculator does not estimate thawing time, energy use, or spoilage.
Estimate a menu item's price from its ingredient cost, target food-cost percentage, and service overhead. This worksheet assumes the target percentage applies to ingredient cost only, then adds the entered overhead per serving.
Estimate the total value of pantry items by multiplying the number of items by their average value per item. This simple estimate assumes one average value applies to every counted item.
Calculate the water and salt needed for a simple pickling brine using the water volume and target salt percentage. This worksheet treats the percentage as salt weight relative to water weight and assumes water weighs about 1,000 grams per liter.
Estimate the ingredient cost per serving for a hospitality recipe and compare it with the menu selling price. The result is an ingredient-only plate cost and menu cost percentage based on the quantities and prices you enter.
Estimate a beverage's pour cost percentage from its ingredient cost per serving and selling price. This simple worksheet compares those two amounts and does not include labor, waste, taxes, or overhead.
Scale an ingredient amount to a new serving count using the recipe’s original servings and the amount you currently use.
Estimate the ingredient cost of a recipe batch and the cost per serving from ingredient quantities, unit costs, and servings. This model covers ingredient cost only.
Estimate the combined mass of items placed in a refrigerator by multiplying the item count by the average mass per item. This estimate does not measure refrigerator capacity or determine safe loading limits.
Calculate a restaurant's profit margin for one period from revenue and total costs entered in the same currency. This user-input arithmetic result is a simple measure, not financial advice.
Calculate the combined volume of sanitizer solution needed for a batch of containers by multiplying the number of containers by the volume in each container. Enter both values in the stated units. This estimates total volume only and does not determine sanitizer concentration or safe use instructions.
Calculate the salt amount for a batch of sauerkraut from the cabbage weight and a chosen salt percentage by weight.
