IELTS Overall Band Score Calculator
Enter your four IELTS section scores — Listening, Reading, Writing and Speaking (0–9 in half-band steps) — and the calculator returns your overall band using the official IELTS rounding rule. The rule is non-standard: a mean ending in .25 rounds UP to the next half band, and a mean ending in .75 rounds UP to the next whole band, so the overall is often higher than a naive nearest-half average.
Section scores
0–9 in 0.5 increments
Each section must be between 0 and 9 in half-band steps (e.g. 6.5).
Overall band
7.0
Good user
Section average: 6.75
Rounding
Operational command with occasional inaccuracies and misunderstandings; handles complex language well.
A mean ending in .25 rounds UP to the next half band; .75 rounds UP to the next whole band. Other means round to the nearest 0.5.
Formula
Overall = round_half((L + R + W + S) / 4), where .25 rounds UP to .5, .75 rounds UP to the next whole band, otherwise round to the nearest 0.5
- · Each of the four sections — Listening, Reading, Writing and Speaking — is reported in half-band steps from 0 to 9.
- · Official rounding rule (published jointly by British Council and IDP): a mean ending in .25 rounds UP to the next half band; a mean ending in .75 rounds UP to the next whole band.
- · Example: 6.5 + 6.5 + 5 + 7 = 25 / 4 = 6.25 → overall 6.5.
- · Example: 7 + 7 + 6.5 + 6.5 = 27 / 4 = 6.75 → overall 7.0 (the .75 boosts you from 6.5 to 7).
- · The overall band is calculated the same way for Academic and General Training — the two versions differ only in the Reading paper and its raw-mark → band conversion.
- · Listening and Reading raw scores convert to band scores via a conversion table that varies slightly between test sessions; this tool assumes you already have your four section bands.

Frequently asked
Why is the IELTS rounding rule so unusual?
IELTS does not just average the four sections and round to the nearest half. The official British Council / IDP scoring rules state explicitly: a mean ending in .25 rounds UP to the next half band, and a mean ending in .75 rounds UP to the next whole band. The reason is to avoid penalising candidates by rounding down on a tied midpoint — e.g. 6 + 6 + 6 + 7 = 6.25, which would round to 6 by ordinary half-up rounding but to 6.5 under IELTS rules. That half-band difference is often the gap between meeting and missing a university or visa requirement.
Is the calculation the same for Academic and General Training?
Yes. Academic and General Training use the exact same overall-band formula — section average plus the same official rounding rule. The two versions differ only in the Reading paper and its raw-mark-to-band conversion table; Listening, Writing and Speaking are identical. So this calculator works for either test.
If my sections are 5.5 but my overall is 6.5, do I still meet a "6.5 IELTS" requirement?
It depends on whether the requirement is on overall band only, or also on minimum per-section bands. Most universities and immigration authorities specify both — e.g. "Overall 6.5 with no section below 6.0." Always read the exact wording. If the requirement is overall-only, you are fine; if it specifies a per-section minimum and one of your sections is below it, you do not meet it even with the right overall. The calculator shows both your overall and your four section scores so you can cross-check.
How do my Writing and Speaking scores become band numbers in the first place?
Writing and Speaking are scored by certified IELTS examiners against four criteria each (e.g. for Writing: Task Achievement, Coherence and Cohesion, Lexical Resource, Grammatical Range and Accuracy). Each criterion gets a 0–9 band; the four are averaged and rounded to the nearest 0.5 to give the paper band. Writing has two tasks combined with Task 2 weighted double; Speaking is a single interview that yields one band directly. This calculator assumes you already have those four section bands and only computes the overall.
