PPD — protein per dollar — is the amount of protein you get for every dollar you spend on a food. Grams per serving tells you what’s in the package; PPD tells you whether the package is worth buying. A Greek yogurt with 12g of protein sounds solid until you compare it to eggs, canned tuna, or chicken thighs at the same price point. ProteinLedger calculates it for any food — scan a label, describe what you’re looking at, and get the number in seconds.

Here’s what PPD actually looks like across foods you probably already buy.

Prices based on US retail, 2026. Your PPD will vary — that’s why you scan your own labels.

Frequently Asked Questions

What's a good PPD score?
As a rough guide: above 15g/$ is solid, above 25g/$ is excellent. Eggs regularly score above 45g/$. Whole milk sits around 35g/$. Most protein bars land between 14–17g/$. Premium ready-to-drink shakes often score below 10g/$ despite the high-protein label. Once you've scanned your usual foods, your own ranking tells you more than any benchmark.
How is this different from just looking up nutrition info online?
A nutrition lookup gives you grams. That's like knowing how big a car's fuel tank is without knowing the MPG. ProteinLedger gives you the ratio — how much protein you actually get per dollar spent, at the price you're seeing in front of you right now. A Google search doesn't know what the salmon costs at your local supermarket today.
Does this work for fresh food without a label?
Yes. Describe the food in text — "200g chicken breast, $4.50" — and ProteinLedger calculates the PPD. For common fresh foods, it uses standard protein density values.
Is there a free version?
Yes. The free tier lets you scan and save up to 15 items. Unlimited saves are available for a one-time purchase of $25.
Does it work outside the US?
Yes. ProteinLedger supports 26 currencies and works in any store, anywhere. Prices are entered in whatever currency you're using.

Most people optimize their training. Fewer optimize what they spend to fuel it.
