Three calculators that answer the questions the guides keep raising. Free, no sign-up, and private: they run entirely in your browser, with no tracking and nothing sent anywhere.

Macro calculator
Maintenance calories from the Mifflin-St Jeor equation, adjusted for a cut, maintenance or a bulk, with protein set in g/kg. The formula is shown with your numbers in it.

Protein cost per 25 g
Label data for 17 protein powders built in. Enter the price and tub size you’re looking at, or any label of your own, and compare on cost per 25 g of protein.

Meal match
Set a per-meal calorie and protein target and rank 114 published meals from Factor, Fuel Meals and FlexPro by how well they fit. Works offline.
Why these are free
They’re the same kind of math Built and Shaped do for you every day, with the working shown. If they’re useful, the apps do this automatically, from your own measured burn and logs. If they’re all you need, that’s fine too.
