Keto Macro Ratio Calculator for Standard 75/20/5 Keto Split

Typical ketogenic macro ratio with 75% calories from fat, 20% from protein, and 5% from carbs based on a ~2,000 calorie diet.

Calculates the ketogenic ratio by dividing fat grams by the combined grams of protein and carbohydrates. Enter your Fat Intake, Protein Intake, Carbohydrate Intake to get an instant ketogenic ratio. Formula: fat_grams / (protein_grams + carbohydrate_grams).

How It Works

How It Works

The Keto Macro Ratio Calculator measures how much fat you eat compared to the total amount of protein and carbohydrates you consume. It uses a simple formula: fat grams divided by the combined grams of protein and carbohydrates.

By entering your daily grams of fat, protein, and carbs, the calculator computes a single number called the ketogenic ratio. This number shows the balance between fat and the other two macronutrients.

  • Add your total fat intake in grams.
  • Add your total protein intake in grams.
  • Add your total carbohydrate intake in grams.
  • The calculator divides fat by (protein + carbohydrates).
  • The result is shown as a single number called the ketogenic ratio.

Understanding the Results

The ketogenic ratio tells you how much fat you are eating compared to protein and carbs combined. A higher number means a higher proportion of fat in your diet.

For example, a ratio of 1.75 means you are eating 1.75 grams of fat for every 1 gram of protein plus carbohydrates combined. This helps you see whether your diet fits your keto goals.

  • A higher ratio means more fat relative to protein and carbs.
  • A lower ratio means more protein and carbs compared to fat.
  • A ratio above 1.0 means fat grams exceed protein and carb grams combined.
  • Use the number to adjust your macro balance if needed.

Frequently Asked Questions

What does the Keto Macro Ratio Calculator measure?

This calculator measures the ketogenic ratio of your diet by dividing fat grams by the combined grams of protein and carbohydrates. The result shows how fat-dominant your diet is compared to protein and carbs. A higher ratio indicates a more fat-focused ketogenic approach.

When should I use the Keto Macro Ratio Calculator?

You should use this calculator when planning or evaluating a ketogenic diet. It is especially helpful if you are following a therapeutic keto diet that requires a specific ratio, such as 2:1, 3:1, or 4:1. It can also help you adjust your macros to stay within your target range.

What is considered a typical ketogenic ratio?

For general ketogenic diets focused on weight loss, ratios often range from 1:1 to 2:1. Therapeutic ketogenic diets, such as those used for epilepsy management, may require higher ratios like 3:1 or 4:1. The appropriate ratio depends on your health goals and medical guidance.

How do I calculate my ketogenic ratio using this tool?

Enter your daily fat intake in grams, along with your protein and carbohydrate intake in grams. The calculator divides fat grams by the sum of protein and carbohydrate grams. For example, if you consume 150g fat, 60g protein, and 30g carbs, your ratio would be 150 ÷ (60 + 30) = 1.67.

Why is my ketogenic ratio lower than expected?

Your ratio may be lower if your protein or carbohydrate intake is relatively high compared to fat. Even moderate increases in protein or carbs can significantly lower the ratio. Reducing carbs or slightly increasing healthy fat sources can raise your ketogenic ratio.

Does this calculator account for calories or percentages?

No, this calculator strictly uses gram amounts to compute the ketogenic ratio. It does not convert values into calories or percentages of total intake. The result is a simple numeric ratio of fat to the combined grams of protein and carbohydrates.
