Your typical weekly activity. Used to estimate your Total Daily Energy Expenditure (TDEE) from your BMR.

What is a Macro Calculator?

"Macros" is short for macronutrients — protein, carbohydrates, and fat, the three nutrients that provide calories. A macro calculator takes a daily calorie target and splits it into gram targets for each of the three, based on a chosen ratio (diet style). Counting macros instead of just calories lets you hit a calorie goal while also controlling nutrient balance — useful for muscle building, fat loss, or managing conditions where carb or fat intake matters.

Macros by Diet Style at 1500 Calories

Every row uses your exact calorie target — only the protein/carb/fat ratio changes.

Diet Style Protein Carbs Fat
Balanced (30/40/30) 150 g 50 g
Low Carb (40/20/40) 75 g 67 g
High Protein (40/30/30) 112 g 50 g
Keto (25/5/70) 19 g 117 g

How Are Macros Calculated?

This calculator first estimates your BMR (Basal Metabolic Rate) with the Mifflin-St Jeor equation, multiplies it by an activity factor to get TDEE (Total Daily Energy Expenditure), then adjusts for your goal before splitting the result into grams using your chosen diet ratio. Protein and carbs each provide about 4 calories per gram; fat provides about 9.

Grams = (Target Calories × Macro %) ÷ (4 for protein/carbs, 9 for fat)

Why Protein Usually Comes First

Most macro plans set protein as a percentage of calories or, more precisely, a target per pound (or kilogram) of body weight — since protein needs scale with lean body mass and activity, not total calories alone. Athletes and anyone in a calorie deficit typically need proportionally more protein to preserve muscle mass, which is part of why "high protein" and low-carb-style plans raise the protein percentage rather than lowering it.

Choosing a Diet Style

A balanced 30/40/30 split works well for general health and is easy to sustain long term. Low-carb and high-protein splits are common for fat-loss phases since higher protein tends to improve satiety. Ketogenic diets push fat intake very high and carbs very low (often under 50g/day) to shift metabolism toward burning fat and ketones for fuel — a much stricter approach that typically requires more careful food tracking to sustain.

Macros Still Depend on Total Calories

Hitting your macro gram targets while ignoring total calories can still stall a weight goal — the diet "style" only controls how calories are divided, not how many calories are consumed overall. Weighing food or using a tracking app for the first few weeks is the most reliable way to confirm your actual intake matches these targets.

Example — Your Current Inputs

At 1500 calories/day on a Balanced (30/40/30) plan, that's 112g protein, 150g carbs, and 50g fat.

Additional Example — A 2,000 Calorie Balanced Plan

At 2,000 calories on a balanced 30/40/30 split, that's 150g protein, 200g carbs, and 67g fat per day. For reference, a 6oz grilled chicken breast has roughly 45g of protein — so reaching 150g protein/day typically means spreading protein sources across 3–4 meals rather than trying to hit the whole target in one sitting.

About These Parameters

Age, Gender, Height & Weight
Used to estimate your BMR via the Mifflin-St Jeor equation, the most widely used and generally most accurate BMR formula for the general population.
Activity Level
Multiplies your BMR to estimate total daily calories burned including exercise and daily movement — overestimating activity is a common reason weight-loss plans stall.
Goal & Diet Style
Goal sets your total calorie target relative to TDEE; diet style only changes how those calories are split between protein, carbs, and fat.

Frequently Asked Questions

Is it better to count macros or just calories?

For pure weight loss or gain, total calories matter most. Macros matter more for body composition goals (preserving muscle while losing fat, or building muscle efficiently while gaining) and for managing how full and energized you feel on a given calorie budget.

How much protein do I actually need?

Common guidance for active adults is roughly 0.7–1g of protein per pound of body weight (about 1.6–2.2g/kg), higher during a calorie deficit to help preserve muscle. The diet-style percentages here are a simpler starting point; adjust protein grams directly if you know your personal target.

Why does a keto plan have so little carbohydrate?

Ketogenic diets intentionally restrict carbs (often to under 5% of calories) to deplete glycogen stores and shift the body toward burning fat and producing ketones for fuel. This is a significant metabolic shift and isn't necessary or appropriate for everyone — check with a healthcare provider before starting, especially with any existing health conditions.
