Food Cost Percentage Calculator
Calculate food cost percentage, prime cost, contribution after entered costs, and cost per portion. The plate-to-margin bridge shows how batch sales are allocated across ingredients, labor, overhead, and the remaining contribution.

How to use Food Cost Percentage Calculator
- Cost the exact edible ingredient quantities used in the batch, including trim and expected waste.
- Enter direct labor and an intentional overhead allocation instead of treating the food-cost percentage as the complete margin.
- Compare contribution and portion cost with menu price, discounts, delivery commissions, taxes, and required profit.
Calculator guide
Understanding Food Cost Percentage Calculator
Food cost percentage answers how much ingredient cost consumes from sales, while contribution answers what remains after entered ingredient, labor, and overhead costs. Keeping those measures separate prevents a low food-cost percentage from being mistaken for strong profit.
Calculation method
How the calculation works
Compare ingredient cost with sales and reconcile labor and allocated overhead to estimate batch contribution and portion cost. Divide ingredient cost by batch sales for food cost percentage. Add ingredient and direct labor for prime cost. Subtract ingredients, labor, and allocated overhead from sales for contribution, then divide entered total cost by portions for cost per portion.
Menu economics
A healthy percentage can still hide a weak item
Percentage, dollars, and operational effort answer different questions.
Worked situations
Practical examples
- $420 ingredient cost against $1,200 batch sales produces a 35% food cost percentage.
- Adding $180 direct labor produces $600 of prime cost before the entered overhead allocation.
- After $95 overhead, the example leaves $505 contribution, or $6.95 entered cost per portion across 100 portions.
Better inputs
Useful tips
- Update ingredient unit costs from recent invoices rather than an old menu-development sheet.
- Convert purchase quantities to edible yield when peel, bone, trim, spoilage, or cooking loss is material.
- Evaluate high-volume low-margin items and low-volume high-margin items as part of the full menu mix.
Before relying on the result
Limitations and common mistakes
- The page does not automatically include payment fees, delivery commissions, discounts, waste variance, tax, or unallocated fixed costs.
- One overhead allocation may not represent actual capacity use, prep complexity, or service time.
- Contribution is not accounting net profit and should be reconciled with the complete operating statement.
Reference
Key terms

Important note
Calculated from the entered quantities using the displayed scaling or conversion method. Ingredient properties, preparation losses, serving needs, and food-safety requirements remain application-specific.
Frequently asked questions
What food cost percentage should I target?
There is no universal target. Concept, labor, rent, service model, waste, pricing power, and required contribution all matter.
Should sales include tax?
Use net sales excluding amounts collected for authorities when that matches the accounting view being compared.
Where do delivery-app fees go?
Add them to the cost model before relying on contribution; the current fields do not include a separate commission input.
Why is contribution not profit?
It excludes any costs not entered, including many fixed, financing, tax, and owner-level costs.
