Enter the points you earned and the total possible to get your score as a percentage, along with how many points you dropped and whether you passed. Set your own pass mark — 50% by default — and it works with whole questions or fractional points alike.
Enter points earned and the total possible.
How it works
The score is simply points earned divided by points possible, times 100: 18 out of 20 is 18 ÷ 20 × 100 = 90%. Points lost is the total minus what you earned, shown so you can see the gap at a glance. The total must be greater than zero, since you can’t score out of nothing.
The pass mark is a percentage you set (default 50%); the tool marks the result as a pass when your percentage reaches or exceeds it. Fractional points are allowed — useful when questions are worth half-marks — and if you earned bonus points beyond the total, the score can exceed 100%.
Practical examples
A quick quiz
You got 18 of 20 questions right. That is 90%, two points short of full marks, and a clear pass at the default 50% threshold.
Points with half-marks
On a test worth 50 points you scored 37.5. That is 37.5 ÷ 50 × 100 = 75% — the fractional point is handled directly.
A higher bar
A certification needs 70% to pass. With 27 correct out of 40 you get 67.5%, which the tool flags as a fail against that mark.
Frequently asked questions
How do I calculate a test percentage?
Divide the points you earned by the total points possible, then multiply by 100. For 15 out of 25 that is 15 ÷ 25 × 100 = 60%.
Can I use it for questions rather than points?
Yes. Enter the number of questions you got right as "earned" and the total number of questions as "total". The percentage is the same calculation either way.
What is the pass mark field for?
It is the percentage needed to pass, which you can change. The tool compares your score to it and labels the result a pass or a fail. It defaults to 50%.
Does reaching the pass mark exactly count as passing?
Yes. If your percentage equals the pass mark — say exactly 50% against a 50% threshold — it is counted as a pass.
Can the score go above 100%?
It can, if you enter more earned points than the total — for example with extra-credit questions. The tool shows the percentage as-is rather than capping it.
Does it give a letter grade?
No. Letter grades and grade boundaries vary by country and school, so the tool reports a percentage and a pass/fail instead of assuming a particular scale.
How is this different from a grade average calculator?
This turns a single test result into a percentage. A grade average calculator combines several grades or marks into an overall average — a different task.
Can I use fractional or decimal points?
Yes. Both fields accept decimals, so half-marks like 37.5 out of 50 work. A decimal comma is accepted as well as a dot.
What happens if I leave the total as zero?
The tool asks for a total above zero, because dividing by zero has no meaning — there would be nothing to score against.
Is my data kept private?
Yes. The calculation runs in your browser; the numbers you enter are never uploaded.
