Cost per serving formula
price after deal / number of servings = cost per serving
Use the serving count from the package when products are used in the same way. If serving sizes are different, compare carefully before treating the result as equal.
Evergreen example
Product A costs $6 for 12 servings. Product B costs $8 for 20 servings. Product A is $0.50 per serving, while Product B is $0.40 per serving, so Product B is cheaper by serving count.
What can mislead you
- Family-size labels: a larger package is not always cheaper per serving.
- Servings per container: the count matters more than the front-label size claim.
- Serving size changes: two products are easiest to compare when the serving size is similar.
- Multipacks: count the total servings across the full pack.
- Bulk packs: bigger packs can still lose after deal math or waste.
