Short answer: there's no official "minus 2 points per missing word" rule — but writing under 250 words is still penalised. It's assessed under the Task Response criterion, which treats an under-length answer as under-developed, and that caps your band regardless of how good the English inside it is.
⏱ Check whether you can actually reach 250+ words in 40 minutes →A persistent myth online claims IELTS deducts a specific number of points for every word you fall short. That's not how it works. There is no arithmetic penalty. Instead, the examiner assessing Task Response is instructed to treat an under-length answer as one that hasn't fully addressed the task, because you literally haven't had the space to develop your position, examples and conclusion the way a complete answer would. The effect can still cap your band meaningfully — it just isn't calculated as a simple subtraction.
This is the part that surprises people: your grammar, vocabulary and coherence can all be genuinely strong, and you'll still be marked down under Task Response for an under-length answer. The criterion isn't just measuring sentence quality — it's measuring whether you've fully developed and supported your argument, and a short answer structurally can't do that as convincingly as a complete one, no matter how polished each individual sentence is.
There's no informal tolerance zone where "close enough" applies. An answer at 235 or 240 words is still under-length and still assessed as such — there's no evidence examiners treat a small shortfall more leniently than a large one under this criterion. Once you're under 250, you're in the same penalised category whether you're 5 words short or 50.
Because there's no reward for landing precisely on 250, and real risk in landing just under it, the only sensible target is comfortably above the line. Our word-count guide covers this in more detail, but the short version is: a small margin above 250 protects you from a slight miscount or a rushed final sentence, without ever risking the floor.
On the paper-based test, there's no automatic counter — candidates typically estimate their count by counting words per line and multiplying, which is imprecise and easy to get wrong under pressure. That makes it genuinely possible to finish believing you've written 260 words when you've actually written 235. On the computer-delivered test, the live counter removes that guesswork entirely — but it introduces a different risk: trusting the exact number and stopping right at 250 with no buffer at all, rather than treating it as a floor to clear comfortably.
Keep writing substantive content — add one more concrete example, or a sentence that develops a point you've already made — rather than stopping to check the count repeatedly. Avoid padding with repetition or filler phrases; examiners notice this immediately and it does nothing for Task Response, since it doesn't add real development to your argument. A rushed but relevant extra sentence is worth far more than empty words added purely to clear the counter.
See what a complete 250-word Band 8 answer looks like →Finishing short of 250 words is almost always a symptom of running out of time, not running out of things to say. If you consistently fall short, the fix usually isn't "write more" in the moment — it's addressing why you're short on time in the first place, whether that's poor time management or a typing speed that's genuinely too slow to convert your ideas into words inside 40 minutes.
No — there's no fixed deduction. An under-length answer is instead assessed as under-developed under Task Response, capping your band.
Any shortfall — there's no informal tolerance zone, so 10 words under is treated the same as 50 words under.
Keep adding relevant content rather than padding with repetition — a rushed relevant sentence helps more than filler.
Comfortably clear 250 rather than stop exactly on it — a small buffer above the minimum, without over-running the 40-minute limit.
