Only the count of correct answers is certain
TOEIC does not publish the table that converts a raw count into a reported score, and the same number of correct answers can produce different scores at different sittings. A number of wrong answers therefore cannot be turned into a score with any certainty. This page splits the job in two. First it subtracts the wrong answers from the question counts to give an exact number of correct answers and an accuracy figure. Then it takes two reference points from the chart you are already reading and estimates a score only within those points. Leave the points blank and no estimate is produced.
How the calculation works
Correct answers are the questions minus the wrong answers, and accuracy is the total correct over the total questions. The estimate is a straight line through your two reference points, and the per-question slope and the formula used are printed with it. If your count falls outside the two points, the result says the line was extended rather than interpolated. The band is your chosen width above and below the estimate, and it never drops below 0.
What this page does not do
With no built-in chart it cannot report an official score. It does not spread a target across the individual parts of the test and it does not forecast a future sitting. The figure is not a prediction, only your own reference points extended.
Frequently Asked Questions
Not exactly. TOEIC does not publish the table that turns a raw count into a reported score, and the relationship is adjusted from one sitting to the next. Only the number of correct answers is certain, so this page calculates that precisely and estimates a score only inside the reference points you supply.
Pick two rows from whichever reference chart you are following, each giving a correct-answer count and the score beside it. The page draws a straight line through those two points, so the estimate is tightest when one point sits below your count and the other above it.
Because no figure is published for how much a sitting can move. The band is simply how cautious you want the range to be, and entering 0 shows a single figure with no band at all.
