Results of the Flesch Grade Level Readability Formula




The Flesch Grade Level readability formula is also commonly referred to as the Flesch-Kincaid Grade Level.

The Flesch Grade Level readability formula takes into consideration (1) the total number of words, and (2) the number syllables, as well as (3) the total number of sentences.

Flesch-Kincaid Grade Level is used in business, industry and government as well as education, to score materials from the upper elementary level through the secondary grades and beyond.

We've processed the following texts through our free Flesch-Kincaid Grade Level Calculator to demonstrate how it works and how to interpret the results.

The specific mathematical formula is:

FKRA = (0.39 x ASL) + (11.8 x ASW) - 15.59

Where, FKRA = Flesch-Kincaid Reading Age
ASL = Average Sentence Length (i.e., the number of words divided by the number of sentences)
ASW = Average number of Syllable per Word (i.e., the number of syllables divided by the number of words)
