Meal prep vs meal delivery: cost and protein per dollar

Every conversation about meal delivery ends the same way. Someone says it’s too expensive, someone else says cooking takes too long, and nobody puts a number on either. If you lift, there’s a better way to settle it: compare everything on what 25 g of protein costs you. It’s about one scoop of most of the protein powders in our label data, or half to three-quarters of a typical high-protein delivery entrée, so it’s a unit you can picture.

This guide shows the method, runs it on the one delivery price we have hard data for, and gives you a worksheet for your own kitchen. It deliberately doesn’t invent grocery prices. Yours are different from mine, and a made-up number would make the comparison look more precise than it is.

The formula

It works for anything with a nutrition label and a price:

cost per 25 g protein = price you paid ÷ total grams of protein you get × 25

For a single meal, “total grams of protein” is just the protein on the label. For a pack of food or a tub of powder, it’s protein per serving multiplied by the number of servings in the pack. If you want protein per dollar instead, flip it: grams of protein ÷ price.

Running it on real delivery data

We collected the published nutrition label for every meal in our data set from Factor, Fuel Meals and FlexPro on September 27, 2026. Only one of the three had a price in that data: FlexPro’s standing entrées were listed at $14.99 each. Across its 25 standing entrées, the average label lists 34.1 g of protein. So:

Put another way, the average FlexPro entrée gives you about 2.27 g of protein per dollar. That’s the number to hold your kitchen up against.

Why no Factor or Fuel Meals figure? Because their prices weren’t in our data. Meal-plan prices often vary with plan size and promotions, so any number we printed without data would be a guess dressed up as a fact. If you have a quote in front of you, the method above takes thirty seconds: divide the per-meal price by the protein on that meal’s label, times 25. For protein, the labels are in the Factor vs Fuel Meals vs FlexPro comparison: Fuel Meals averaged 45.2 g per entrée and Factor 37.1 g.

Running it on your own cooking

Home cooking is often the cheaper option per gram of protein, but by how much depends entirely on what you buy and where, so check it rather than assume it. Here’s how to get your own number from one grocery receipt:

1. Pick your protein anchors. Whatever you actually cook with most: chicken thighs, lean ground beef, eggs, Greek yogurt, tofu, canned tuna.
2. Read the label for total protein. Protein per serving × servings per pack. For raw meat, use the label on the pack (it’s usually per raw weight), not a cooked-weight figure from an app.
3. Divide the price by that total, times 25. That’s the cost of 25 g of protein from that item.
4. Add what goes with it. Rice, vegetables, oil and sauce carry cost but little protein. Add their share of the price to the meal, not to the protein item, then divide the whole meal’s cost by the whole meal’s protein.

The protein cost tool does steps 2 and 3 for you. It’s built for protein powder, but its “enter your own label” row works for any food with a label: enter protein per serving, serving size, pack size and price.

The costs that aren’t on the receipt

Time

This is the real argument for delivery. Shopping, cooking and cleaning up a week of lunches takes a few hours of your week. Whether that’s worth paying to avoid depends on what your hours are worth and what else you’d do with them. If you work on your feet and get home wrecked, it can be worth a lot.

Waste

Food you buy and don’t eat still costs money. A cheap pack of chicken that goes off in the fridge has an infinite cost per gram of protein. Delivery meals have a use-by date too, so only order what your week can actually absorb.

Consistency

A delivery meal has a label, so it’s the same every time and it’s easy to log. Home cooking drifts: a heavier pour of oil, a bigger portion of rice. That doesn’t make it worse, but it makes precise tracking more work.

Protein per calorie

Cost isn’t the only efficiency that matters. On a cut, what you get per calorie counts too. In our data, Fuel Meals averaged 8.5 g of protein per 100 kcal, FlexPro 7.4 g and Factor 6.4 g. Home cooking can beat all three if you build it lean, or lose to all three if you don’t.

The hybrid most people end up with

In practice, it’s rarely all or nothing. A setup that works for a lot of busy people:

• Cook the cheap, easy meals. Breakfast is usually the easiest to do at home: eggs, yogurt, oats.
• Use delivery for the meal you’d otherwise skip or buy on the run. For many people that’s lunch on a work day. A labeled meal beats a drive-through you can’t log.
• Fill the gap with the cheapest protein per gram you’ll actually eat. Often that’s powder, but check with the tool rather than assuming.

Work out your own cost per 25 g for each option and the right mix usually becomes obvious.

Worksheet

That last row is the honest one. The real alternative to a delivery meal often isn’t a perfect home-cooked lunch; it’s whatever you grab when you didn’t plan. Put that on the sheet too.
