Home › Food Business Calculators › Recipe Unit Price Calculator
Normalize a package price to a comparable unit so you can evaluate ingredient value across different package sizes. Enter the package price, package quantity and its unit. The calculator reports a standard rate per 100 g or 100 mL, plus larger or familiar comparison units.

Mathematical model
The engine first converts the package quantity into its base unit. For mass, the base is grams; for volume, the base is milliliters; for item counts, the base is each. Unit price = package price ÷ normalized package quantity. It then multiplies or divides that rate to display cost per 100 g, per kilogram and per pound for mass; per 100 mL, per liter and per US fluid ounce for volume; or per item for countable goods.
The calculator keeps the entered currency unchanged. It does not convert currencies, include shipping, account for discounts or decide whether two products are equivalent in quality or composition.
Verified numerical example
A 500 g package costs 3.99. The rate is 3.99 ÷ 500 = 0.00798 per gram. The calculator reports 0.798 per 100 g (about 0.80), 7.98 per kilogram and about 3.62 per pound. A 1,000 g package at 7.50 would cost 0.75 per 100 g, so it is cheaper by this normalized price measure.
For a volume example, a 2 L bottle costs 3.50. Since 2 L = 2,000 mL, the rate is 3.50 ÷ 2,000 = 0.00175 per mL, or 0.175 per 100 mL and 1.75 per liter.
How to use the calculator
- Enter the full package price in your currency.
- Enter the net package quantity, not the outer carton count unless the unit is each.
- Select the unit that matches the quantity: mass, volume or item count.
- Calculate and compare the same normalized basis across products.
Fair comparison and limitations
Compare mass with mass, volume with volume, and count with count. A kilogram price cannot be compared directly with a liter price unless a valid ingredient density is available and the products are truly comparable. The tool does not convert weight into volume or account for drained weight, edible yield, quality, concentration or waste.
A lower unit price is not automatically better value if the product has a different grade, concentration, ingredient composition, shelf life or usable yield. Check package labels and compare like-for-like quantities. Use the same currency and include relevant delivery or membership fees separately if they affect the purchase decision.
Frequently asked questions
Why compare price per 100 g?
It puts different package sizes on a common mass basis, making the price easier to compare.
Can I compare liters with kilograms?
Not directly. Volume and mass are different dimensions. A reliable density is needed to convert between them.
Does the result include discounts?
Only if you enter the final price you actually pay. The calculator does not apply coupons or shipping automatically.
