How this is worked out
The total price is divided by the quantity or size to give the price per unit.
Worked example
- Total price £4.50
- Quantity 6 units
4.50 ÷ 6
£0.75 per unit
Assumptions and limits
- Only comparable when both products are measured the same way, so convert grams and kilograms, or millilitres and litres, before comparing.
- Rounded to the nearest penny, so very small units may show as £0.00.
