Unit price is the cost per standard unit of measurement (e.g., per ounce, per liter, per count). It allows you to compare products of different sizes and brands on an equal basis. Instead of being misled by a lower sticker price on a smaller package, you can see which option truly offers the best value. This is especially useful when comparing bulk packs versus regular sizes, or name brands versus store brands. Many grocery stores now display unit prices on shelf labels, but our tool lets you compare anywhere—online or in-store.

The formula is simple: Unit Price = Total Price ÷ Quantity. For example, if a 16 oz jar of peanut butter costs $4.48, the unit price is $4.48 ÷ 16 = $0.28 per ounce. If a larger 40 oz jar costs $9.80, its unit price is $9.80 ÷ 40 = $0.245 per ounce—making the larger jar the better deal. Our tool automates this calculation and also standardizes units so you can compare products measured in different units (like ounces vs. pounds).

Not always! While bulk packages often offer a lower unit price, this isn't guaranteed. Manufacturers sometimes price smaller "convenience" packs competitively during promotions. Additionally, store brands in smaller packages can beat name-brand bulk prices. It's also worth considering waste and storage—buying a gallon of milk when you only need a quart isn't a good deal if half of it spoils. Always compare unit prices using our tool to make informed decisions.

Choose the unit that matches the product type:

Weight oz, lb, g, kg — for solids like flour, meat, cheese, cereal
Volume fl oz, ml, L, gal — for liquids like juice, milk, detergent
Count count, dozen, pack — for discrete items like eggs, rolls, cans

Our tool automatically detects the category and standardizes units for fair comparison. For example, if one product is in lb and another in oz, both are converted to $/oz for an apples-to-apples comparison.

In the US and many other countries, shelf price tags often include a small unit price label (e.g., "¢28.0 per oz" or "$3.49 per lb"). These are usually printed in the corner of the price tag. However, be cautious: different stores may use different base units for the same type of product (one store might show $/oz while another shows ¢/lb for similar items). Our tool helps you standardize everything so you can compare across stores and online retailers with confidence.

Price/Unit is calculated directly from your input: total price divided by the quantity you entered, expressed in your chosen unit. Std. Price (Standardized Price) converts all products in the same category to a common base unit—$/oz for weight-based products, $/fl oz for volume-based products, and $/count for count-based products. This standardization enables fair cross-comparison even when products use different units (e.g., comparing a product sold in pounds to one sold in ounces).

• Compare across brands: Store brands often match or beat name-brand unit prices.
• Check sale prices: A "50% off" sticker might still be more expensive per unit than a bulk option.
• Watch for shrinkflation: When package sizes decrease but prices stay the same, the unit price rises.
• Consider usage: The best unit price only saves money if you actually use the product before it expires.
• Use our tool before major shopping trips: Compare prices across different retailers online before heading out.
• Don't ignore quality: Unit price shows value, but product quality, ingredients, and preferences matter too.
