Test Grade Calculator
The test grade calculator handles all. Enter your score however it comes, number of questions right, number wrong, or raw points out of a total, and it converts everything into a percentage, a letter grade, and a GPA value all at once.
How to Use the Test Grade Calculator
Three Ways to Enter Your Score
Mode 1: # Wrong
This is the fastest option for standard multiple-choice tests where you know how many you missed. Enter the total number of questions and how many you got wrong. The test grade calculator figures out the rest.
Mode 2: # Correct
Same idea, opposite direction. If you counted the ones you got right instead of the ones you missed, use this mode. On a 40-question test, entering 33 correct gives you the same result as entering 7 wrong. Pick whichever number you already have.
Mode 3: Points
This is where it gets useful for anything beyond a simple multiple-choice quiz. Enter the points you earned and the total points possible, and they do not have to be whole numbers. Got 37.5 out of 45? That works. Got 82 out of 100? That works too. The points mode supports decimals, partial credit, and rubric-based scoring, which the other two modes do not.
Once you have entered your score, you will see your percentage, letter grade, and GPA all at once in the result card on the right. If you want to compare your score against a target, enter the Target % in the Target % field; more on that below.
This is the mode that makes the test grade calculator genuinely useful for college-level coursework, not just high school quizzes. Most competitors in this space only handle the simple right-or-wrong format, skipping everything else.
The Cutoff Table: Every Score, Every Grade, Every GPA
The cutoff table works the same way as the quick table on the easy grade calculator, but with one important addition: the GPA column.
Every row shows the number wrong, number correct, the percentage, the letter grade, and the GPA value, all calculated based on your current grading scheme and GPA scale settings. It is generated automatically when you enter your test details and updates whenever you make changes.
The table is capped at 200 rows, which covers the vast majority of tests. If your test has more than 200 total questions or points, the table shows the first 200 possible scores, starting from 0 wrong.
That second use case is where it gets psychologically interesting. Seeing that one wrong answer costs you 2.5 percentage points and that dropping from 87% to 84.5% means the difference between a B+ and a B makes every question feel like it matters. Which, on most tests, it does.
Frequently Asked Questions: Test Grade Calculator
What is the difference between the test grade calculator and the easy grade calculator?
The easy grade calculator is built for speed: two inputs, instant letter grade, done. This calculator adds a points mode for tests scored in points rather than questions, GPA output, target tracking with gap display, and curve grading context. Use the easy calculator for a quick score lookup. Use this one when you need the full picture.
How do I calculate a test score that includes partial credit?
Switch to Points mode. Add up all your partial credit scores across every question to get your total points earned, then enter that number along with the total points possible on the test. The calculator converts the ratio to a percentage, and everything else follows. For example, if you earned 3.5 out of 5 on one question and 4 out of 5 on another, your total is 7.5 out of 10.
Can the test grade calculator handle curved grades?
The calculator itself does not apply a curve automatically; it does not know what curve your professor used. But once you know the curve amount, whether it is a flat percentage added to everyone’s score or a highest-score adjustment, enter your post-curve score, and the calculator shows you the updated grade. The cutoff table lets you compare your raw and curved scores side by side.
How does the GPA scale work?
The calculator maps your letter grade to a GPA value based on the scale you set. The default is the 4.0 standard US college scale. If your school uses a 5.0 scale, common in honors programs and some high schools, set the GPA scale to 5.0; the GPA value will be adjusted proportionally. An A that is worth 4.0 on a 4.0 scale becomes 5.0 on a 5.0 scale.
What does the target percentage feature do?
It shows you the gap between your actual score and a target you set. If you need 85% to maintain your course grade and you scored 82%, the calculator displays “Needed difference to target: +3.00%.” This turns a grade into a specific, actionable number about what needs to happen next.
Why does the cutoff table only show 200 rows?
For performance reasons, generating thousands of rows would slow down the page on mobile devices. 200 rows cover the vast majority of tests (anything up to 200 questions or 200 total points). If your test is larger than that, you can still use the main calculator for your specific score.
Can I edit the letter grade thresholds?
Yes, but only when the US Letters scheme is selected. Click “Edit thresholds” to adjust any boundary. For the UK, ECTS, and Australian schemes, the thresholds are set to standard values for those systems.
Does this calculator work for standardized tests like the SAT or AP exams?
Not directly; standardized tests use proprietary scoring systems. SAT scores range from 400 to 1600; AP exams use a 1-5 scale. This calculator converts raw scores to percentages and letter grades, as is common in most college coursework. For standardized test score interpretation, you will want the official score reports from the testing organization.
How is rounding handled?
All percentages are rounded to two decimal places using standard rounding (round half up). So 74.995% becomes 75.00%, and 74.994% stays at 74.99%.
Is my information private?
Yes. Nothing you enter is stored or sent anywhere. The calculator runs entirely in your browser. Share buttons only activate when you click them.
