IELTS Writing band calculator — Task 1 and Task 2

Combining Writing criteria and task weights

Choose four whole-band criterion scores for each task. Task 1 uses task achievement; Task 2 uses task response. Both also include coherence and cohesion, lexical resource, and grammatical range and accuracy. Each task score is the arithmetic mean of its four criteria. These means remain unrounded before the tasks are combined.

The combined value is Task 1 plus twice Task 2, divided by three. For example, task averages of 6 and 7 produce 6.667 before the estimated final rounding to 6.5. We apply the same nearest-half-band method as the overall calculator for consistency. The exact official internal Writing rounding procedure is not published, so this is an estimate. Selecting a criterion score does not assess an essay; use feedback from a qualified teacher to make the inputs meaningful.

Use the calculator and keep a scenario

Start with scores you actually have, then change one input at a time to explore a realistic target. Empty fields are deliberately left empty: a missing score is not treated as zero. The result updates when you choose a value, without a separate calculation button. Your selections are included in the page address, so copying the address lets someone else open the same scenario. Changing a value updates the current address without adding a browser history entry. Reloading or sharing that address restores the valid values. The calculator runs in your browser and does not submit these values to a scoring API.

Turn a number into a practice plan

A calculated score is useful when it leads to a specific next step. Compare several fresh attempts rather than treating one unusually strong practice result as your settled level. Notice which skill or criterion limits your progress, practise that area, and repeat the check with new material. An estimate cannot certify language ability or guarantee a result on test day. For IELTS, the linked free Reading or Listening mock gives you a timed task and feedback on individual answers.
