Strong listening, average productive skills	Academic	36	27	6.0	6.5	6.5
General training candidate near band 8	General Training	38	37	7.0	7.5	7.5
Developing candidate with reading weakness	General Training	25	20	5.5	6.0	5.5

Formula Used

This calculator predicts overall IELTS band by converting raw Listening and Reading answers into estimated band scores, then combining them with Writing and Speaking bands.

Step 1: Convert Listening correct answers out of 40 into a Listening band.

Step 2: Convert Reading correct answers using either Academic or General Training mapping.

Step 3: Use your estimated Writing and Speaking bands.

Step 4: Calculate the exact average:

Average Band = (Listening + Reading + Writing + Speaking) / 4

Step 5: Apply IELTS rounding rules:

Decimals below 0.25 round down, 0.25 to 0.74 round to .5, and 0.75 or above round up to the next whole band.

Frequently Asked Questions

1) Is this predictor exact?

No. It is an estimate based on entered raw scores and band assumptions. Listening and Reading are mapped from correct answers, while Writing and Speaking remain user-estimated unless official results are available.

2) Why does Reading depend on exam type?

Academic and General Training Reading sections use different raw-score-to-band conversions. The same number of correct answers can lead to different band scores depending on the chosen module.

3) How is the overall band rounded?

The exact average of the four section bands is calculated first. Then IELTS rounding is applied: values near .25 round to .5, and values near .75 round to the next full band.

4) Can I use half bands for Writing and Speaking?

Yes. The calculator accepts half-band values such as 6.5 or 7.5. This helps produce more realistic predictions when using teacher feedback or consistent mock test performance.

5) What is the confidence adjustment?

It slightly increases or decreases Writing and Speaking estimates by up to 0.5 band. It helps model uncertainty when your productive-skill scores are not yet confirmed by expert marking.

6) Should I trust raw score mappings forever?

Use them as a practical guide, not a guarantee. Test versions and official interpretation practices may vary slightly, so this tool is best for planning and progress tracking.

7) Why is my target gap important?

The target gap shows how far your predicted overall band is from the score you need. It helps prioritize study time, especially when one weaker skill limits the final average.

8) Can this tool help with study strategy?

Yes. It highlights the weakest section and compares your current result with a target band. That makes it easier to focus on the skills most likely to improve your final score.
