Best Free Keto Macro Calculator Online in 2026 — Net Carbs, No Sign-up
What the Calculator Provides
Keto Macros Calculator outputs: daily net carb limit, protein target (lean mass × 1.5g), fat target (remaining calories after protein and carbs), total calories, and the macro split as percentages. Supports SKD, high-protein keto, and TKD variations.
Why Lean Mass Matters for Keto Protein
Standard macro calculators use total body weight for protein calculation. Keto protein should be calculated from lean body mass (total weight × (1 − body fat %)). Using total weight overstates protein needs for people carrying significant fat mass, which can elevate gluconeogenesis and impair ketosis.
Using the Output for Meal Planning
With 25g net carbs, 100g protein, and 165g fat targets: each meal (3 meals/day) should contain roughly 8g net carbs, 33g protein, and 55g fat. These gram targets make meal assembly much more practical than working from percentage targets alone.
