Maintenance Macro Calculator

Use this maintenance macro calculator to determine your daily calories, protein, carbs, and fats required to maintain your current weight and support overall health and performance.

Maintenance calories refer to the number of calories your body needs to maintain its current weight. These calories are equal to your total daily energy expenditure (TDEE Calculator), which includes energy used for basic bodily functions and physical activity.

In simple terms, if you consume the same number of calories that your body burns daily, your weight will remain stable.

According to research from institutions like the World Health Organization, maintaining energy balance is essential for long-term health, metabolic stability, and proper body function.

Unlike bulking or cutting phases, maintenance focuses on balance rather than surplus or deficit.

Maintenance macros are calculated by distributing your daily calorie needs into three primary macronutrients:

• Protein supports muscle repair and preservation.
• Carbohydrates provide energy for daily activity and workouts.
• Fats support hormones and overall health.

A maintenance macro calculator works by:

This ensures your body gets the right balance of nutrients without gaining or losing weight.

Your macro ratio at maintenance should be balanced to support both performance and recovery.

Common Maintenance Macro Split

General guidelines

• Protein: around 1.6 to 2.0g per kg body weight
• Fats: around 20 to 30% of total calories
• Carbs: remaining calories for energy

This balanced approach helps maintain muscle mass, support metabolism, and keep energy levels stable throughout the day.

Maintenance is often overlooked, but it plays a critical role in long-term fitness success.

You should consider staying at maintenance if:

• You are satisfied with your current body composition
• You want to stabilize weight after a bulk or cut
• You are focusing on strength or performance rather than size
• You want to improve metabolic health and consistency

From experience working with fitness-focused users, maintenance phases help prevent burnout, improve recovery, and create a sustainable approach to nutrition.

If you also track body composition changes during maintenance, use the Body Fat Calculator.
