Recipe Cost Calculator — illustrative example

INPUT
A 1 kg bag of rice costs USD 3; recipe uses 200 g. Other used ingredients total USD 1.40; recipe makes 2 servings.

RESULT
Rice cost: 200 ÷ 1,000 × USD 3 = USD 0.60.
Ingredient total: USD 2.00, or USD 1.00 per serving.
Labor, energy and unlisted waste are excluded.

REVIEW
Recipe costing should use the amount consumed from each purchase and account for yield where relevant. Show packaging, waste and overhead separately from ingredient cost.
