Enter two percentages along with their respective weights into the calculator to determine the combined percentage. This calculator helps in finding the weighted average of two percentages.

Combined Percentage Formula

The following formula is used to calculate the combined percentage.

CP = frac{(P1 times W1) + (P2 times W2)}{W1 + W2}

Variables:

  • CP is the combined percentage
  • P1 is the first percentage
  • P2 is the second percentage
  • W1 is the weight for the first percentage
  • W2 is the weight for the second percentage

To calculate the combined percentage, multiply each percentage by its respective weight, add the results together, and then divide by the sum of the weights.

What is a Combined Percentage?

A combined percentage is a weighted average of two or more percentages. It is used to find a single percentage that represents the relative importance of different percentages with different weights. This is commonly used in academic grading, financial analysis, and other areas where different percentages contribute to a final outcome based on their significance.

How to Calculate a Combined Percentage?

The following steps outline how to calculate the combined percentage.


  1. First, determine the first percentage (P1).
  2. Next, determine the weight for the first percentage (W1).
  3. Then, determine the second percentage (P2).
  4. Next, determine the weight for the second percentage (W2).
  5. Use the formula CP = (P1 * W1 + P2 * W2) / (W1 + W2) to calculate the combined percentage (CP).
  6. Finally, calculate the combined percentage (CP).
  7. 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.

First percentage (P1) = 70%

Weight for the first percentage (W1) = 3

Second percentage (P2) = 85%

Weight for the second percentage (W2) = 2
