Frequently Asked Questions
What is unit price and why is it important?
Unit price is the cost per standardized unit of measurement (per ounce, liter, pound, etc.). It's important because it allows you to fairly compare products of different sizes. A larger package might have a higher total price but could actually be cheaper per unit, saving you money in the long run.
How do I compare products with different units?
Our calculator includes built-in conversions for common units. For example, if one product is priced per ounce and another per pound, you can convert both to the same unit for accurate comparison. Simply select your preferred unit and the calculator will handle the conversion.
Does a lower total price always mean better value?
No! This is a common shopping misconception. A smaller package might have a lower sticker price but could cost more per unit. For example, a $3 bottle of 16oz juice costs $0.19/oz, while a $5 bottle of 32oz juice costs only $0.16/oz - the $5 bottle is actually the better value despite the higher total price.
Should I always buy the lowest unit price option?
Not necessarily. Consider storage space, expiration dates, and actual usage. Buying a giant bulk package with the lowest unit price isn't cost-effective if half of it expires before you use it. Factor in whether you'll actually consume the product before it goes bad.
How do I factor in sales and coupons?
Use the sale price calculator feature to enter the discounted price or apply your coupon savings. This gives you the true unit price after discounts, which might change which product is the best value. A product with a higher regular unit price could become the better deal when on sale.
Can I use this for comparing different types of products?
While the calculator works for any products with quantifiable units, it's most useful for comparing the same or similar products in different sizes. Comparing completely different products (apples to oranges) requires considering quality, features, and personal preferences beyond just unit price.
What about quality differences between brands?
Unit price shows economic value, but quality matters too. A generic brand might have a lower unit price but if you need to use twice as much to get the same results, it may not be the better value. Consider effectiveness and quality alongside unit price for the complete picture.
Is my shopping data stored anywhere?
No. All calculations happen entirely in your browser. No product data, prices, or comparisons are stored, logged, or transmitted to any server. Your shopping analysis remains completely private.
