Calculate women-to-men ratio and inclusive workforce shares, or estimate additional women hires needed for a target representation percentage with parity and gap metrics.

Use mutually exclusive headcounts from the same population and date. Shares include all three categories; the ratio compares women with men.

Enter 0 if none; do not count a person in more than one category.

Gender Diversity Ratio Formula

The following formula is used to calculate the gender diversity ratio as a female-to-male ratio. The ratio compares women and men; category shares use T = F + M + O, including the another-identity or undisclosed category O. Counts must be mutually exclusive.

R = F / M

Variables:

  • R is the gender diversity ratio (female-to-male ratio, F ÷ M)
  • F is the number of females
  • M is the number of males
  • T is total headcount (T = F + M + O, where O is another identity or undisclosed)

To calculate the gender diversity ratio, divide the number of females by the number of males. A value of 1.00 indicates equal numbers of females and males; values above 1.00 indicate more females than males, and values below 1.00 indicate more males than females.

In the additional-women scenario, the other headcounts remain fixed and the total grows. For a target fraction p below 1, the minimum addition is the nonnegative whole-number ceiling of (pT − F)/(1 − p). A 100% target cannot be reached by finite additions when other categories are present. This arithmetic scenario does not measure inclusion or prescribe individual hiring decisions.

What is a Gender Diversity Ratio?

The gender diversity ratio is a simple representation metric that compares the number of female employees to the number of male employees (F ÷ M). It can help organizations describe gender representation and track changes over time. Note that gender diversity can include more than two categories; the ratio compares the women and men counts provided, while category shares retain the additional or undisclosed count in the total.

How to Calculate Gender Diversity Ratio?

The following steps outline how to calculate the Gender Diversity Ratio.

  1. First, determine the number of females (F).
  2. Next, determine the number of males (M).
  3. For category shares, calculate total headcount T = F + M + O; include another-identity or undisclosed headcount O.
  4. Finally, calculate the gender diversity ratio using the formula R = F / M.
  5. After inserting the values 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.

Number of females (F) = 30

Number of males (M) = 20

Total number of employees (T) = 50 when another-identity or undisclosed headcount is 0.

Gender diversity ratio (R) = 1.50
