Enter the total number of types and the total number of tokens into the Type-Token Ratio Calculator. The calculator will evaluate the Type-Token Ratio. 

Type-Token Ratio Formula

The following two example problems outline the steps and information needed to calculate the Type-Token Ratio.

TTR = TYP / TOK * 100

Variables:

  • TTR is the Type-Token Ratio (%)
  • TYP is the total number of types 
  • TOK is the total number of tokens 

How to Calculate Type-Token Ratio?

The following steps outline how to calculate the Type-Token Ratio.


  1. First, determine the total number of types. 
  2. Next, determine the total number of tokens. 
  3. Next, gather the formula from above = TTR = TYP / TOK * 100.
  4. Finally, calculate the Type-Token Ratio.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :
