Meal Prep Cost Estimator

Where the money actually goes

Two inputs drive nearly everything on this page: what a recipe costs you and how many servings it makes. Divide one by the other and you get cost per serving, which is the number that follows you all month. Inside that number, protein is usually the largest single line, and right behind it sits the convenience premium: the extra you pay for someone else to portion, trim, marinate, or package the same food. Pre-cut vegetables, single-serve yogurt cups, seasoned chicken, and shakes already in a bottle are the same ingredients in a smaller, more expensive format. Rice, oats, beans, lentils, potatoes, frozen vegetables, and eggs stay inexpensive almost everywhere. I am deliberately not quoting grocery prices here, because they swing hard by region and go stale fast. The comparisons hold even when the price tags do not.

A worked example

Say you eat 21 meals a week, a meal out runs you 12 in whatever currency you picked, and one recipe costs 15 and makes 4 servings. Cost per serving is 15 divided by 4, so 3.75. The tool then rounds up to whole recipes, because you cannot cook three quarters of a batch: 21 divided by 4 is 5.25, which becomes 6 recipes, so 90 for the week. Eating out for those same 21 meals is 252. That is 162 saved weekly, and 701.46 monthly, since the month here is 4.33 weeks rather than a flat 4. Notice the rounding leaves you 24 servings for 21 meals, so three future lunches are already paid for. Stretch that same recipe to 5 servings and you need only 5 recipes, which drops the week to 75.

Cheap protein is still protein

Your body does not price-check your food. Eggs, canned tuna, whole chicken, frozen chicken thighs, cottage cheese, milk, plain yogurt in a large tub, dried lentils, and store-brand whey all deliver the same amino acids as the premium version of themselves. Buying the larger format and portioning it yourself is where most of the real saving lives, and frozen produce is picked ripe and frozen fast, so it is not a downgrade either. If you want to see how much protein you are actually aiming for before you shop, the protein calculator gives you the target, and the macro calculator fills in the rest.

What batch cooking really saves

The dollars are only half of it. Cooking once for six servings spends roughly the same time as cooking once for two, so the hourly return on a Sunday afternoon is genuinely good. The quieter win is decision fatigue. Every meal you have not planned is a decision made while hungry and tired, and those decisions cost the most. A fridge with food already in it removes that choice entirely. Two or three recipes a week, cooked in one session and mixed and matched, covers most of a week without anyone eating the same plate seven times.

The plan you can afford

A plan you can pay for every single week beats an optimal one you abandon in three, every time. If the weekly number this tool gives you feels tight, do not scrap the whole approach: drop one expensive recipe, raise the servings per batch, or move a few meals to the cheaper staples and rerun it. If the savings line comes back negative, that is useful information too, not a failure. It usually means the recipe cost is high relative to what it yields, so the fix is servings per recipe rather than willpower. When you want to sanity check how many meals you actually need in a day, meal frequency is a reasonable next stop. Eat food you like, at a price you can repeat, and let the consistency do the work.
