How unit price comparison works
Compare two package prices by cost per matching unit.
Formula and convention
Unit price = package price / quantity. Savings compare the cheaper price to the more expensive one.A worked example
A at 6 per 500 units costs 0.012 per unit. B at 10 per 1,000 costs 0.010 per unit.
Scope and precision
Use the same unit for both quantities. Quality, waste, taxes, discounts, and storage costs are not assessed.
