Cost per wash formula
price after deal / number of washes = cost per wash
For pods, washes usually match pod count. For powder or gel, use the realistic wash count based on the amount you would actually use.
Evergreen example
Product A costs $9 for 45 washes. Product B costs $14 for 70 washes. Product A is $0.20 per wash, while Product B is also $0.20 per wash, so the price math is tied before convenience or preference.
What can mislead you
- Pods vs powder vs gel: format can change convenience, but the price math still starts with cost per wash.
- Pack count: pod count is useful, but only after dividing by price.
- Realistic wash count: powder and gel depend on the dose you actually use.
- Sale labels: percent-off and multi-buy tags can hide the effective cost per wash.
