How to use the unit price comparison
The calculator converts each package quantity into a common base unit, multiplies by pack count, and divides price by the total quantity. Weight comparisons are displayed per kilogram, volume comparisons per litre, and count comparisons per item. The relative saving is the unit-price difference divided by the higher unit price. This compares the cost of an equal quantity rather than simply choosing the cheaper package.
Can I compare ounces and millilitres?
No. The ounce option means a unit of weight, not a fluid ounce. Compare weight with weight, volume with volume, or items with items. Converting between weight and volume would require the product’s density.
What else affects value?
Quality, usable yield, shelf life and the amount you will actually consume matter. Enter prices with the same tax treatment, and account for required memberships or shipping consistently.
How should I compare scenarios?
Start with the example, then replace every relevant value with your own figures. Keep the currency and time periods consistent. Change one assumption at a time and calculate again to see its effect. The initial values are examples, not recommended rates, prices or budgets. When comparing alternatives, include the same categories in each scenario so that a missing expense does not make one choice appear cheaper.
Can I save or share the result?
Use Copy summary for a concise text result, or Export CSV for the available figures. Calculations run in your browser; entered amounts are not uploaded by this tool. An exported file contains your information, so choose where to store or share it. Displayed amounts are rounded to two decimal places, while most intermediate calculations retain additional precision. Small differences from a bill or statement can therefore occur.
What should I check before using the numbers?
Read the calculation assumptions beside the result and confirm the inputs against the relevant quote, agreement or records. This tool provides an estimate based on those inputs, not an approval, market forecast or personalized financial recommendation. Refresh the calculation when your circumstances or the underlying terms change.
