IELTS Band Score Calculator Formula
The IELTS Band Score Calculator formula calculates calculate an IELTS overall band score or a TOEFL iBT total from the four skill section results.
This formula is used because it connects the main inputs directly to the result people need.
It keeps the work clear, so you can change one value and see how the answer moves.
IELTS reports Listening, Reading, Writing and Speaking from 0 to 9 in half-band steps, and the overall band is their mean rounded to the nearest half band. TOEFL iBT reports the same four skills from 0 to 30 and simply adds them for a total out of 120. This tool covers both.
