The Hidden Math of Unit Pricing
How retailers use different package sizes to hide a 20% markup, and how to spot it instantly.
1. The Complexity Gap
Retailers rely on the "Complexity Gap"—the mental friction created when comparing 450g to 1.2kg, especially when one is on sale. They intentionally avoid round numbers to make mental math harder.
2. How to Normalize
To beat the gap, you must normalize to a single base unit (usually 100g or 1kg). CalcFact does this by stripping away the marketing fluff and showing you the raw cost-per-unit, regardless of the package size.
3. The Bulk Trap
Always check if the "Family Pack" is actually cheaper. Often, mid-sized packages on promotion have a lower unit price than the oversized bulk version. Don't assume big equals cheap.
