Unit Price Calculator

What is the Unit Price Calculator?

Compare two products by unit price to find the better deal. Quick, everyday math — splitting the bill, checking a sale, comparing prices at the store or scaling a recipe — shouldn’t need a spreadsheet. These calculators answer it in a second.

How to use the Unit Price Calculator

1. Enter your item a price, your item a quantity, your item b price, your item b quantity.
2. Results update automatically as you type; you can also press Calculate.
3. Read the output: better deal, item a unit price, item b unit price, savings with the better deal.
4. Use the 📊 chart to see the result visually, then copy or share it.

Formula and method

Worked example

With item a price = $4.99, item a quantity = 16, item b price = $7.49, item b quantity = 28, the Unit Price Calculator returns better deal: Item B is cheaper per unit; item a unit price: $0.3119; item b unit price: $0.2675.

Tips for better results

• Stacked discounts multiply rather than add: 30% + 20% off is 44% off, not 50%.
• Compare unit prices, not package prices, to find the real deal.
• Bookmark the tools you use often — every page works offline once loaded.
