The IELTS band score calculator above does one thing precisely and one thing approximately, and it keeps the two clearly apart. Precisely: it averages your four section bands and applies the official rounding rule, which is published by IELTS and is fixed, so the overall band it returns is arithmetic rather than estimate. Approximately: in its optional raw mode it converts Listening and Academic Reading correct-answer counts into bands using only the indicative anchor points IELTS itself publishes, and it labels everything between those anchors as an interpolation.
Arb Digital drew that line deliberately. It is easy to publish a complete raw-score conversion table that looks authoritative, and there is no way for a reader to check it. IELTS does not publish a full mark-by-mark table because the conversion is adjusted for each test version so that a given band means the same thing regardless of which paper you sat. Any page presenting an exact 40-row table is presenting a guess. This one shows what is actually published, and says so where it stops.
What This IELTS Band Score Calculator Does
In band mode it takes your Listening, Reading, Writing and Speaking bands, adds them, divides by four, and rounds the result to the nearest half band using the rule IELTS states on its scoring page. It reports the unrounded average alongside the rounded band, which matters because the two often differ in ways that surprise people. It also shows the lowest of your four sections and how many total band points across all four would be needed to reach the next half band overall.
In raw mode it additionally converts a Listening or Academic Reading correct-answer count into an approximate band, using the four anchor points IELTS publishes and straight-line interpolation between them. Outside the published range it refuses to guess and tells you to enter the band from your score report instead. Writing and Speaking are always entered as bands, because they are examiner-judged against the published descriptors and there is no raw mark to convert.
How to Use It
- Choose your mode. If you already have four bands from a score report, band mode is exact. Raw mode is for practice tests where you have counted correct answers.
- Enter the four values. Bands go in half-band steps from 0 to 9. Raw counts go from 0 to 40 for both Listening and Academic Reading.
- Read the unrounded average as well as the band. An average of 6.4 and an average of 6.74 both round to 6.5, but they are a long way apart in practice.
- Check the "points to next half band" figure. It tells you how much total improvement across all four sections would change the rounded result.
- Verify against your official Test Report Form. That document, not this page, is the authoritative record of your score.
The Formula and the Official Rounding Rule
The overall band is the mean of the four section bands, rounded to the nearest half band. IELTS states the two edge cases explicitly on its IELTS scoring in detail: band scores explained page: if the average ends in .25 the overall band rounds up to the next half band, and if it ends in .75 it rounds up to the next whole band. Every other average simply goes to the nearer half band.
Work the default through. Listening 7, Reading 6.5, Writing 6, Speaking 7 sum to 26.5. Divide by four and the average is 6.625. The two candidate half bands are 6.5 (a distance of 0.125) and 7.0 (a distance of 0.375), so the nearer one wins and the overall band is 6.5. Now raise Writing to 6.5. The sum becomes 27, the average becomes 6.75, and the published rule sends that straight up to a whole band: the overall becomes 7.0. Half a band in one section moved the overall by half a band.
The general implementation is simply to double the average, round half up to the nearest whole number, and halve it again — which reproduces both published edge cases exactly, since .25 doubles to .5 and rounds up, and .75 doubles to 1.5 and rounds up. Because section bands come in half-band steps, the four-way average always lands on a multiple of 0.125, so only eight distinct fractional positions are possible and every one of them is covered by that single rule.
Why There Is No Official Raw-to-Band Table
This is the part most IELTS calculators get wrong. IELTS publishes indicative anchor points — for Listening, a raw score of 16 corresponds to band 5, 23 to band 6, 30 to band 7 and 35 to band 8; for Academic Reading the anchors are 15, 23, 30 and 35 for the same four bands. Those are the published figures and they are what this tool uses. It does not publish a value for every raw score from 0 to 40, and the conversion is adjusted between test versions.
The reason is equating. Test papers vary slightly in difficulty no matter how carefully they are written, and the point of a band scale is that band 7 means the same level of English on every sitting. So the raw-to-band mapping is set per version to compensate: a marginally harder Reading paper needs a slightly lower raw score for the same band. That is a feature of a properly run examination, not an inconsistency, and it is exactly why an invented 40-row table is worse than useless — it will be wrong by a mark or two in an unpredictable direction, which is precisely the margin people care about.
What this means practically: use raw mode for a rough read on a practice test, and use band mode with the figures from your Test Report Form for anything real. If your practice material came with its own conversion key for that specific paper, that key is better evidence than any general table, including the anchors here.
Academic and General Training Are Not Interchangeable
IELTS runs two test types, and its official test types page sets out the difference: Listening and Speaking are identical across both, while the Reading and Writing sections differ because they target different contexts. Academic is aimed at study in an English-speaking country; General Training is aimed at migration and workplace English.
The consequence for this calculator is specific and important. The published Reading anchor points above are for Academic Reading. General Training Reading uses a different conversion, and the same raw score does not produce the same band. If you sat General Training, use band mode and enter the Reading band from your report rather than a raw count. The Listening anchors do apply to both, since the Listening test is common to the two versions. Mixing the two conversions is one of the more common ways people end up with a wrong estimate and then a surprise on results day.
Reading the Unrounded Average
Two candidates can hold the same overall band and be in genuinely different positions. An average of 6.5 exactly and an average of 6.74 both print as 6.5. The first is at the bottom of that band with a quarter of a point to find before the next step; the second is a hair below the rounding boundary and a single half-band gain anywhere would tip it to 7.0. The rounded band alone hides that, which is why the unrounded average is on this page as a first-class figure rather than a footnote.
The same logic explains why section improvements have uneven leverage. Because the average is over four equally weighted sections, one half-band gain adds 0.125 to the average. Depending on where you sit relative to the rounding boundary, that 0.125 either changes the overall band or does nothing visible at all. The grid figure labelled "total band points to next half band" makes that explicit: it converts the distance to the boundary back into the number of section band points you would need across all four papers.
What This Page Cannot Tell You
Three limits, stated plainly. It cannot predict what you will score on a future sitting — it does arithmetic on numbers you supply and nothing else. It cannot tell you how an examiner would band your Writing or Speaking, because those are judged against detailed published descriptors by a trained examiner and no calculator substitutes for that. And it does not comment on whether any band is sufficient for any university, employer, or immigration route, because requirements are set by those organisations, vary constantly, and often specify minimum section bands as well as an overall figure.
For the last of those, the only reliable source is the receiving institution's own current published requirement, read directly. The general information on the official IELTS website covers the test and the score scale itself, which is what this tool is built on. If you are preparing written material in English for study or work purposes, our word frequency counter and headline analyzer are general writing utilities rather than exam tools, but they are useful for spotting repetition in a draft.

- Rounding the average down at .25 or .75 — the published rule sends both of those upward, to the next half band and the next whole band respectively.
- Using an Academic Reading conversion for General Training — the two Reading papers convert differently, so the same raw count gives different bands.
- Trusting a full 40-row raw conversion table — IELTS publishes anchor points, not a complete table, and the mapping is adjusted per test version.
- Rounding each section before averaging — sections are already reported in half bands, so there is nothing to round; rounding twice will change the answer.
- Assuming the overall band is all that matters — many institutions also set a minimum for individual sections, and an overall figure can hide a section below that floor.

Frequently Asked Questions
Add the Listening, Reading, Writing and Speaking bands, divide by four, and round to the nearest half band. IELTS states that an average ending in .25 rounds up to the next half band and one ending in .75 rounds up to the next whole band.
No. It publishes indicative anchor points, such as a Listening raw score of 30 corresponding to band 7, and the conversion is adjusted between test versions so that a band means the same level of English on every sitting.
No. The two Reading papers are different tests with different conversions, so the same number of correct answers does not give the same band. Listening and Speaking are common to both test types.
Because of the published .25 and .75 rule. An average of 6.75 goes up to a whole band 7.0 rather than staying at 6.5, and an average of 6.25 goes up to 6.5.
No. It performs arithmetic on the numbers you enter. It cannot judge Writing or Speaking, which are marked by an examiner against published descriptors, and it cannot anticipate the version of the test you will sit.
It adds 0.125 to the four-section average. Whether that changes the rounded overall band depends entirely on how close the average already sits to a rounding boundary.
No. All four sections and the overall score are reported in whole and half bands only. The quarter values appear solely as intermediate averages before rounding.
