Cost Per Serving Calculator
Divides a recipe or pack's total cost by how many servings it makes, and pits two options against each other so you can see which is cheaper per plate.
How it works
The core math is simple division: a $12 tray of lasagna that feeds four costs $3 a serving. Where it earns its keep is comparing two things that aren't the same size — a bigger pack usually wins per serving, but not always, and eyeballing the shelf price won't tell you.
Put option A and option B in side by side and the calculator flags the cheaper one and roughly how much less it costs per serving. That's the number that matters when you're deciding between the family pack and the single, or a homemade batch versus a ready meal.
It works for anything you portion out — coffee pods, protein bars, meal-kit dinners, a batch of soup. As long as you know the total cost and how many servings you get, you'll see the real per-plate price instead of guessing from the sticker.
Frequently asked questions
What counts as a serving?
Whatever portion you actually eat — it's up to you to be consistent. If you compare two options, use the same idea of a serving for both, or the comparison won't mean much. A recipe that says 'serves 6' is a fine starting point.
Is the bigger pack always cheaper per serving?
Usually, but not guaranteed — promotions, bulk markups, and odd pack sizes can flip it. That's exactly why the side-by-side compare is here: enter both and let the per-serving numbers settle it instead of assuming.
Can I include prep or cooking costs?
If you want the fuller picture, add estimated energy or extra-ingredient costs into the total before dividing. For a quick grocery comparison, the pack or recipe price alone is usually enough to spot the better value.
