What this calculator does
The IELTS Band Score Calculator computes your overall band from the four section scores using the exact rule the British Council and IDP apply. IELTS rounding is unusual — it snaps to the nearest half or whole band — so a manual average often gives the wrong answer. Enter your four scores and the tool handles the rounding correctly.
How it works
First the four section bands are averaged with equal weight:
average = (Listening + Reading + Writing + Speaking) / 4
Then IELTS rounding is applied to the average. A fractional part of .25 rounds up to the next half band, and .75 rounds up to the next whole band. Anything below those thresholds rounds down to the nearest half:
6.25 -> 6.5
6.75 -> 7.0
6.125 -> 6.0
Each section is reported only in 0.5 steps, and so is the overall band. Because it is an average, the overall band always falls between your weakest and strongest sections.
Tips and example
Suppose you scored Listening 6.5, Reading 6.5, Writing 5.0, and Speaking 7.0. The sum is 25.0, divided by four is 6.25, which rounds up to an overall band of 6.5. Notice how the weak Writing section is partially offset by the rounding. If you are just below a required band, lifting your weakest section by half a point is often enough to clear the next rounding threshold — use the raw average shown below the result to see how close you are.
