About price per volume
Divides each price by its quantity to produce a comparable per-fl oz figure. Larger packages are not always cheaper, so this shows the real unit cost.

Assumptions and limits
- The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
- Simple arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions
Do bigger sizes always win?
No — unit pricing reveals when the 'bulk' size actually costs more per unit.
How accurate is this estimate?
Rates are approximate reference values. Local rates, exemptions and rules can differ, so treat the output as a planning figure only.
