A LITTLE LOOK INSIDE
Compare a price.
See the difference.
Calculate a unit price with your own numbers, then explore a few illustrative examples.
Keep ongoing records on paper or in your own spreadsheet. This site does not save or import records.
FIXED FICTIONAL RECORDS
Same item. Different value.
Try it: Choose an example → compare the price per unit → check the package total.
Worked example: $2.88 ÷ 32 oz = $0.090/oz. The $3.84 bag is $0.080/oz, but costs more at checkout.
A lower unit price can still mean spending more today. These are illustrative prices, not current store quotes.
ILLUSTRATIVE WEEKLY PLAN
Keep a little room.
In this fixed example, a $200 total budget includes a $20 stock-up allowance. The allowance is part of the budget, not extra money.
- Regular groceries
- $162.00
- Stock-up items
- $16.00
- Tax and other costs
- $8.00
- Planned total
- $186.00
- Left in total budget
- $14.00
- Unused stock-up allowance
- $4.00
Sample only. No shopping list or budget is saved.

Enter the package price and total size, then choose a comparison unit. Use matching products and units when comparing results.
Unit price = package price ÷ size in the comparison unit. For multipacks, enter the total size (for example, 6 × 12 fl oz = 72 fl oz). Prices are in USD; include discounts or tax consistently. US liquid measures are used. Weight, liquid, count and labeled loads cannot be mixed. A zero price is allowed; package size must be greater than zero.
