Your overall IELTS band score is the average of your four skill scores: Listening, Reading, Writing and Speaking. Each skill gets a band from 0 to 9 in whole or half bands. IELTS adds the four together, divides by 4 and rounds the result to the nearest half band. One detail decides many results: an average that ends in .25 or .75 is rounded up.
Here is the example IELTS itself uses: Listening 6.5, Reading 6.5, Writing 5.0, Speaking 7.0. The four add up to 25, and 25 ÷ 4 = 6.25, which becomes an overall 6.5.
Half a band in one skill often decides the overall. In 1 of 4 full mock exams on GoPrep (578 of 2,307), half a band more in any one skill would have lifted the overall by half a band (15 July to 26 September 2026, Writing and Speaking scored by the GoPrep AI examiner).
There is no pass or fail in IELTS. The score you need is set by your university, employer or visa authority (what counts as a good IELTS score for your goal). So first check the score you need, then work out which four scores give it.
Where the four scores come from
Every skill counts for exactly a quarter of the overall, but the four scores are produced in two different ways:
- Listening and Reading have 40 questions each, 1 mark per question. Your raw score (the number of correct answers out of 40) is converted to a band. In the IELTS figures, about 30 correct answers give band 7 in Listening and in Academic Reading. General Training Reading uses a different table: there, about 30 correct answers give band 6. IELTS notes that the exact number of marks for each band varies slightly from one test version to another. The full tables are in our guides to the Listening band score and the Reading band score.
- Writing is marked by an examiner on four criteria of equal weight: Task Achievement (Task Response in Task 2), Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. Task 2 counts twice as much as Task 1. What each criterion asks for: IELTS Writing band descriptors. How to plan the essay: IELTS Writing Task 2 guide.
- Speaking is marked on four criteria of equal weight: Fluency and Coherence, Lexical Resource, Grammatical Range and Accuracy, and Pronunciation. More in IELTS Speaking band descriptors.
Each skill score is reported in whole or half bands, such as 6.0 or 6.5. The overall score is where the rounding rule comes in.
The rounding rule, with worked examples
Because each skill score moves in half bands, an average of four can only end in eight ways. IELTS rounds it to the nearest half band. In the two cases that sit exactly halfway, .25 and .75, it rounds up.
| Average ends in | Overall band | Example |
|---|---|---|
| .0 | Stays the same | 6.0 → 6.0 |
| .125 | Down to the whole band | 6.125 → 6.0 |
| .25 | Up to the half band | 6.25 → 6.5 |
| .375 | Up to the half band | 6.375 → 6.5 |
| .5 | Stays the same | 6.5 → 6.5 |
| .625 | Down to the half band | 6.625 → 6.5 |
| .75 | Up to the next whole band | 6.75 → 7.0 |
| .875 | Up to the next whole band | 6.875 → 7.0 |
Now the full calculation for five candidates. The first three are the examples on ielts.org.
| Listening, Reading, Writing, Speaking | Total and average | Overall band |
|---|---|---|
| 6.5, 6.5, 5.0, 7.0 | 25 ÷ 4 = 6.25 | 6.5 (.25 rounds up) |
| 4.0, 3.5, 4.0, 4.0 | 15.5 ÷ 4 = 3.875 | 4.0 (nearest whole band) |
| 6.5, 6.5, 5.5, 6.0 | 24.5 ÷ 4 = 6.125 | 6.0 (nearest whole band) |
| 7.0, 6.5, 6.0, 7.0 | 26.5 ÷ 4 = 6.625 | 6.5 (nearest half band) |
| 7.0, 6.5, 6.5, 7.0 | 27 ÷ 4 = 6.75 | 7.0 (.75 rounds up) |
Look at the last two rows. The only difference is Writing: 6.0 in one, 6.5 in the other. Half a band in one skill moved the overall from 6.5 to 7.0. This is the 1 in 4 case from the start of this guide: an average ending in .125 or .625 is 0.125 below the next rounding threshold, and adding 0.5 to one skill closes that gap.
Why one weak skill pulls your overall down
All four skills carry the same weight, so the average doesn't care where your points come from. Each skill is a quarter of the average: half a band in any skill changes the average by 0.125, and the rounding rule decides whether the overall changes with it.
Take Listening 7.0, Reading 7.0, Speaking 7.0 and Writing 5.0. The total is 26, the average is 6.5, and the overall is 6.5, although three skills out of four are at 7.0. Lift Writing to 6.0 and the total becomes 27, the average 6.75 and the overall 7.0.
Uneven scores are the norm. In 93% of full mock exams on GoPrep, the gap between the strongest and the weakest skill was a full band or more, and in 3 of 4 it was 1.5 bands or more (2,307 full mock exams, 15 July to 26 September 2026, Writing and Speaking scored by the GoPrep AI examiner).
The weakest skill is not the same for everyone. Across the same mock exams, the lowest-scoring skill varied:
| Skill | Average band | Weakest (or joint weakest) skill in |
|---|---|---|
| Listening | 5.5 | 39% of exams |
| Reading | 5.5 | 34% of exams |
| Writing | 5.5 | 40% of exams |
| Speaking | 6.0 | 17% of exams |
The averages sit within half a band of each other, and every skill was the lowest-scoring one in a noticeable share of exams. General advice can't tell you which skill holds you back. Your own four scores, from a full mock or your last real test, can.
A weak skill can also miss a minimum of its own. Some universities, employers and visa authorities set a minimum for each skill as well as for the overall, for example "6.5 overall with no skill below 6.0". Someone with 7.0, 7.0, 6.5 and 5.5 has an overall of 6.5 and still misses it. This is common. 62% of first full mock exams with an overall of exactly 6.5 had at least one skill below 6.0 (127 of 204), and 68% of those with an overall of exactly 7.0 had at least one skill below 6.5 (70 of 103):
| Example requirement | First exams with exactly this overall | Of them, a skill below the minimum | Skill below the minimum |
|---|---|---|---|
| 6.5 overall, no skill below 6.0 | 204 of 1,362 | 127 of 204 (62%) | Listening 57, Writing 44, Reading 32, Speaking 11 |
| 7.0 overall, no skill below 6.5 | 103 of 1,362 | 70 of 103 (68%) | Writing 34, Listening 23, Reading 14, Speaking 14 |
In both examples, more than 6 in 10 results with exactly the required overall still missed the skill minimum. Check the exact wording on your university or visa page, and treat a per-skill minimum as a second target. If that skill is Listening, our IELTS Listening tips show where each part of the test loses marks.
If one skill falls short and the other three are fine, IELTS One Skill Retake lets you retake that single skill, with conditions. Your full test must be IELTS on computer at a centre that offers One Skill Retake, and you sit the retake within 60 days of it, once per test. You get a new Test Report Form with the new score and your three original ones, and you choose which report to use. Before you book, check that your university, employer or visa authority accepts a One Skill Retake result. When it is the right choice, and when a full retake fits better, is in our IELTS One Skill Retake guide. If you think a Writing or Speaking score was marked too low, an IELTS remark (EOR) is the other option.
What each band means
IELTS gives every whole band a name and a short description. A half band, such as 6.5, sits between two levels.
| Band | Skill level | What it means |
|---|---|---|
| 9 | Expert | Full command of English: accurate, fluent and appropriate, with complete understanding |
| 8 | Very good | Full command with only occasional, unsystematic mistakes |
| 7 | Good | Works well in English, with occasional mistakes and misunderstandings in some situations |
| 6 | Competent | Effective command despite some mistakes and misunderstandings |
| 5 | Modest | Partial command: gets the overall meaning in most situations, but makes many mistakes |
| 4 | Limited | Basic competence in familiar situations only, with frequent problems understanding and expressing |
| 3 | Extremely limited | Understands and conveys only general meaning in very familiar situations |
| 2 | Intermittent | Great difficulty understanding spoken and written English |
| 1 | Non-user | No ability to use English beyond a few isolated words |
| 0 | Did not attempt the test | No questions answered |
For a sense of scale: 12% of first full mock exams on GoPrep (164 of 1,362) reached an overall of 7.0 or higher (15 July to 26 September 2026, Writing and Speaking scored by the GoPrep AI examiner). To see which CEFR level (B2, C1 and so on) your band matches, read IELTS and CEFR levels.
Work backwards from your target score
You can also count the other way: from the overall you need to the total of four scores. The lowest average that still rounds to your target is a quarter band below it. Multiply that average by 4 and you have the total:
| Target overall | Lowest average | Total of the four scores | One way to get there |
|---|---|---|---|
| 5.5 | 5.25 | 21 | 5.5 + 5.5 + 5.0 + 5.0 |
| 6.0 | 5.75 | 23 | 6.0 + 6.0 + 5.5 + 5.5 |
| 6.5 | 6.25 | 25 | 6.5 + 6.5 + 6.0 + 6.0 |
| 7.0 | 6.75 | 27 | 7.0 + 7.0 + 6.5 + 6.5 |
| 7.5 | 7.25 | 29 | 7.5 + 7.5 + 7.0 + 7.0 |
The same total can come from very different scores. That doesn't matter for the overall, but it matters as soon as there is a minimum for each skill. Here are four practice routes checked against one example requirement:
| Listening, Reading, Writing, Speaking | Total and overall | Meets the requirement? |
|---|---|---|
| 7.0, 7.0, 5.0, 7.0 | 26, overall 6.5 | No: the total is 1 band short |
| 7.0, 7.0, 6.0, 7.0 | 27, overall 7.0 | Yes |
| 8.0, 7.0, 5.0, 7.0 | 27, overall 7.0 | No: Writing is below 6.0 |
| 7.5, 7.5, 6.0, 6.0 | 27, overall 7.0 | Yes |
The third route is the trap. A high Listening score reaches the total, but no score in another skill can lift Writing to the minimum. With a per-skill minimum, raise the skills below it first. Without one, adding 0.5 to any skill raises the average by the same amount.
Practice: calculate the overall band
FAQ
How is the IELTS overall band score calculated?
Add your Listening, Reading, Writing and Speaking band scores, divide the total by 4 and round to the nearest half band. An average ending in .25 rounds up to the next half band and one ending in .75 rounds up to the next whole band, so 6.75 becomes 7.0 and 6.625 becomes 6.5.
Are all four IELTS sections weighted equally?
Yes. Listening, Reading, Writing and Speaking each count for a quarter of the overall band. Inside the Writing test, Task 2 counts twice as much as Task 1.
Can one low score bring down my overall IELTS band?
Yes. Scores of 7.0, 7.0, 7.0 and 5.0 average 6.5, so in this example a 5.0 instead of 7.0 in one skill lowers the overall from 7.0 to 6.5. If your university sets a minimum for each skill, you can also miss that minimum in one skill even when your overall is high enough.
Is 7 a good score in IELTS?
Band 7 is officially called good: you work well in English, with occasional mistakes and misunderstandings. The official IELTS and CEFR comparison is approximate: 7.0 corresponds to C1, the B2 to C1 boundary falls between 6.5 and 7.0, and 6.5 sits between competent (6) and good (7). Whether it is enough depends on your university, employer or visa authority, including any minimum for each skill.
Is 4.5 a good score in IELTS?
Band 4.5 sits between limited (4) and modest (5) and falls in the CEFR B1 range on the official comparison. There is no pass or fail, so it depends on the requirement you need to meet. An overall of 4.5 comes from a total of 17 to 18.5 across the four skills, and 6.0 needs a total of 23.
What band is 32 out of 40 in IELTS?
It depends on the skill and the test. In the usual conversion tables, 32 correct answers is about band 7.5 in Listening, 7.0 in Academic Reading and 6.5 in General Training Reading. The exact cut-offs vary slightly from one test version to another.
What IELTS band is A1, A2, B1, B2, C1 or C2?
The official IELTS and CEFR comparison is approximate and refers to the overall band: 4.0 to 5.0 is roughly B1, 5.5 to 6.5 B2, 7.0 to 8.0 C1 and 8.5 to 9.0 C2. Bands 5.0, 6.5 and 8.0 sit near the boundaries between levels. IELTS does not officially link bands below 4.0 to A1 or A2.
Can I retake just one section of IELTS?
Yes, if your full test was IELTS on computer at a centre that offers IELTS One Skill Retake. You can retake one skill within 60 days of that test, once per test, and then choose between the new and the original Test Report Form. Check first that your university, employer or visa authority accepts the retake result.
