What Recipe Cost Calculator does, with a checked example
Enter what each ingredient costs, how much of it you bought, how much the recipe uses, and how many servings it makes. The tool converts each price to a cost per unit - per ounce, pound, cup, or piece - multiplies by the amount used, sums the lines into a total recipe cost, and divides by servings for a per-serving food cost. The usual mistake is pricing the whole package rather than the amount used, and treating the result as the full cost of the dish when it is ingredient cost only.
Worked example
A concrete input and expected output from the current implementation.
Input
Recipe: garlic butter pasta, 4 servings
Pasta: 16 oz used, $2.00 per 16 oz box
Butter: 4 oz used, $4.00 per 1 lb
Garlic: 2 oz used, $2.40 per lb
->
Expected output
Line costs: pasta $2.00 (16 oz x $0.125/oz); butter $1.00 (4 oz x $0.25/oz); garlic $0.30 (2 oz x $0.15/oz). Total recipe cost: $3.30. Per-serving cost for 4 servings: $0.83.
Each line is unit cost times amount used, and the total is divided by the serving count. $3.30 / 4 = $0.825, which rounds to $0.83 - which is why 4 x $0.83 does not exactly match the $3.30 total.
