How to Compare Store Brand vs Name Brand by Cost Per Serving
Store brand and name brand products can have different package sizes, serving counts, and sale tags. Compare same-use products by the serving count before deciding which one is cheaper.
The cost per serving calculator lets you enter your own price and serving count, then compare both products with the same math.
The Simple Formula
Cost per serving = price after deal / total servings
This works best when the products are used in the same way and the serving size is reasonably comparable.
Generic Example
This example uses hypothetical products only, so it does not depend on current prices or brand claims.
| Product | Price | Servings | Cost per serving | Verdict |
|---|---|---|---|---|
| Product A store brand | $5.00 | 10 | $0.50 | Higher per serving |
| Product B name brand | $7.00 | 20 | $0.35 | Better value |
Product B has the higher shelf price, but the lower cost per serving in this example. The result is about price math only, not taste or quality.
Why Same-Use Products Matter
Cost per serving is most useful when the products solve the same shopping need. If one product uses a much smaller serving size or works differently, the serving comparison may not be enough by itself.
Common Traps
- Different serving counts: a cheaper shelf price can hide fewer total servings.
- Sale labels: percent-off and multi-buy deals change the effective price.
- Package size: weight or volume can differ even when products sit beside each other.
- Multipacks: count all servings across the full bundle.
- Unit mismatch: serving math works best when the serving sizes are comparable.
