Protein per dollar, per ounce, per calorie
Type in what the label says and get one sentence back: how much protein a dollar buys here, and what 20 g of it costs.
Before the numbers
Has a clinician set limits on your protein, fluid, sodium or potassium?
We never ask for a condition and never store one — this is one of three words kept in this browser, and you can clear it on your device page. Nothing below is hidden either way.
The protein and cost figures below are general reference figures from published sources and from product labels. They are not a target, they are not personalised, and nothing here adjusts them for age, kidney function, heart or blood-pressure conditions, pregnancy or anything else. A clinician is the only person who can set a number for you.
The label
Start with a typical label, then edit the numbers to match the one in your hand. Generic examples, not products we sell.
Or type the label yourself
Use fl oz for a drink as you actually drink it (including the water you mix in), g for a powder scoop, bar or cup.
The answer
Type in what the label says and the answer appears here.
Protein per serving and serving size are the two it needs; price and servings unlock the cost line.
Runs in your browser. Nothing you type here is sent anywhere, and copying, printing or saving happens on your own device.
Compare a few
Nothing added yet. Fill in a label above and add it, then change the numbers and add the next one — they stack up here for comparison.
Why volume is the number that matters on a small appetite
When appetite drops, the useful question stops being “how much protein is in this?” and becomes “how much protein is in the amount I can actually finish?” A 30 g shake you drink half of is a 15 g shake. That is why the calculator asks for the serving as you actually make it, water and all, and reports protein per fluid ounce alongside the price.
Read this before you trust the numbers
- This is arithmetic on the numbers you type. It is not a recommendation, and it cannot tell you whether a product suits you.
- There is no universal protein target. Most clinicians set one with the person in front of them, based on body size, kidney function, medication and goals. Ask yours what your number is — we will not invent one for you.
- Cheapest per gram is not the same as best. A tub that costs less per 20 g and sits unopened because it tastes wrong is the more expensive product. So is one that upsets your stomach.
- Serving sizes on labels are often smaller than what you would pour. Enter the serving as you actually make it, including any water or milk you mix in, or the per-ounce figure will flatter the product.
- We researched and compared these categories from labels, specs and owner reviews. We do not run taste panels or lab assays.
