Calculate ingredient usage cost, total recipe cost, cost per serving, scaled recipe cost, and optional whole-package purchase estimates from prices you enter.
Normalize recipe and package quantities to compatible units, divide effective package price by package quantity, then multiply by the amount used.
Usage cost values the ingredients consumed. Optional whole-package cost estimates checkout spending separately.

Three eggs from a 12-pack costing $4.80 cost $1.20.
1 1/2 cups from a 6-cup package costing $4 costs $1.
Flour $2, sugar $0.60, and eggs $1.20 total $3.80; four servings cost $0.95 each.
A recipe needing 500 g from a 1 kg, $4 bag uses $2 but requires a $4 purchase, leaving 500 g.
Scaling four servings to six uses a 1.5× factor; an $8 linear ingredient cost becomes $12.

Mass and volume cannot be compared without ingredient-specific density.
Leftover package quantities may be useful later and are not labeled waste.
Shared converters handle compatible mass and volume units. Count and matching custom units use direct ratios. Fractions and mixed numbers use the Recipe Scaling parser.
A single fixed or percentage package discount can be applied before unit pricing. Direct-price mode supports prices such as $2.50 per kilogram.
Usage cost is the primary recipe-cost result. Whole-package checkout cost, remaining quantity, and approximate remaining value are separate estimates.
Scaled mode applies the shared serving scale factor to each raw ingredient quantity, then recalculates its cost without multiplying rounded displays.
Add the usage cost of every included ingredient.
Divide effective package price by normalized package quantity and multiply by recipe quantity.
Divide total recipe cost by entered servings.
Enter the flour amount used, the bag quantity, and the price paid. Compatible weight units are normalized before finding usage cost.
Enter the package amount and price for each ingredient. The normalized unit price is applied to the recipe quantity.
Yes.
Yes, with count or matching custom units.
Yes, through shared mass conversion.
Yes, through shared volume conversion.
No. Ingredient-specific density would be required and is not inferred.
Usage cost values what the recipe consumes; purchase cost totals required whole packages.
Leftovers do not increase ingredient usage cost. Whole-package mode shows their approximate remaining value separately.
Yes. Scaled mode recalculates every ingredient from the serving factor.
No. Enter all prices yourself.
No. It estimates ingredient cost, not business pricing or profit.
