Enter the bulking calories consumed and the normal calories consumed into the Calculator. The calculator will evaluate the Bulk Percentage. 

Bulk Percentage Formula

BP = BCC / NCC * 100


  • BP is the Bulk Percentage (%)
  • BCC is the bulking calories consumed
  • NCC is the normal calories consumed

To calculate Bulk Percentage, divide the bulking calories consumed by the normal calories consumed, then multiply by 100.

How to Calculate Bulk Percentage?

The following steps outline how to calculate the Bulk Percentage.

  1. First, determine the bulking calories consumed. 
  2. Next, determine the normal calories consumed. 
  3. Next, gather the formula from above = BP = BCC / NCC * 100.
  4. Finally, calculate the Bulk Percentage.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

bulking calories consumed = 2500

normal calories consumed = 2000

Frequently Asked Questions

What is bulking in fitness?

Bulking in fitness refers to the process of eating more calories than your body needs for a set period, with the aim of gaining muscle mass. This often involves consuming a higher amount of proteins, carbohydrates, and fats to support muscle growth and recovery.

How do I know if I’m consuming enough calories for bulking?

To ensure you’re consuming enough calories for bulking, you should first calculate your Total Daily Energy Expenditure (TDEE) and then increase that number by a certain percentage—usually between 10% and 20%. Using tools like the Bulking Calculator can help you determine the exact number of calories you should consume.

What is the difference between clean and dirty bulking?

Clean bulking focuses on gaining muscle mass with minimal fat gain by consuming healthier food choices, whereas dirty bulking pays less attention to the quality of calories consumed and often results in higher fat gain due to the consumption of calorie-dense but nutrient-poor foods.

How long should a bulking phase last?

The duration of a bulking phase can vary depending on individual goals, but it typically lasts between 4 to 6 months. It’s essential to monitor your progress and adjust your calorie intake as needed to ensure you’re gaining muscle mass at a healthy rate without accumulating excessive fat.
