Grade Calculator
Turn points and weights into a letter grade (A–F) and GPA points.
Your assignments
Assignment weights must add up to 100%. For example, a midterm worth 50% and a final worth 50%.
Uses the standard US letter scale (A+ 97–100 down to F below 60). Schools vary — some use different cutoffs or no plus/minus grades — so confirm your school's scale before using the result officially. Need to work out what score you need on a final exam? Try the final grade calculator.

Grade calculator — percentage to letter grade and weighted grades
A grade calculator converts a percentage into a letter grade and GPA points, or combines weighted assignments into one final grade. Enter 92% and you get A− worth 3.7 grade points; enter your assignments with their weights and you get your final percentage and letter grade for the course.
The two modes answer two different questions. The percentage mode is for a single score: a test, a quiz, or a course average you already know. The weighted mode is for a whole course, where each assignment counts differently — a midterm worth 50% moves your final grade far more than homework worth 10%, so the calculator multiplies each assignment's percentage by its weight before adding them up. Your weights must add up to 100%.
This calculator is different from the final grade calculator, which works backwards: it tells you the exam score you still need to reach a target grade. Use that one when the final exam is still ahead of you, and this one when all your scores are in.
How the grade calculator works
Percentage first, then the letter. Enter a percentage to get its letter grade and GPA points on the standard scale (A+ 97–100, A 93–96, A- 90–92, B+ 87–89, B 83–86, B- 80–82, C+ 77–79, C 73–76, C- 70–72, D+ 67–69, D 63–66, D- 60–62, F below 60). Or enter weighted assignments — earned points, total points and weight for each — and the calculator works out your final percentage first, then the letter.
Letter cutoffs vary by school, so treat the result as a guide. Your syllabus is the official source for your course's scale.

How to use the grade calculator
- Choose a mode: percentage to letter grade for a single score, or weighted grade for a whole course.
- For a single score, enter your percentage (0–100).
- For a weighted grade, enter each assignment's points earned, total points, and weight % — weights must add up to 100%. Add or remove rows with the buttons.
- Press Calculate grade to see your letter grade and GPA points on the 4.0 scale.
Frequently asked questions
What letter grade is 92%?
On the standard scale, 92% is an A−, worth 3.7 GPA points on the 4.0 scale. The A− band runs from 90% to 92%; 93% and above is a plain A.
What letter grade is 89.5%?
89.5% is a B+, worth 3.3 GPA points. The B+ band runs from 87% to 89%, so 89.5% sits just under the A− cutoff of 90%.
How do I calculate a weighted grade?
Multiply each assignment's percentage by its weight, then add the results. For example, 90% on a midterm worth 50% plus 80% on a final worth 50% is (90 × 0.50) + (80 × 0.50) = 85%, a B. Your weights must add up to 100%.
What is the difference between this and the final grade calculator?
This grade calculator works out your grade from scores you already have. The final grade calculator works backwards: given your current grade, the final exam's weight, and the grade you want, it tells you the exam score you need.
How many GPA points is an A+?
On the standard 4.0 scale, an A+ is worth 4.0 — the same as a plain A. Some schools use a 4.3 scale where A+ is worth 4.3; use the GPA calculator if your school uses that scale.
Do all schools use the same grade scale?
No. The scale here is the most common US one, but cutoffs vary — some schools start A at 90% with no plus/minus grades, and others use different bands. Always check your school's grading policy before using a letter grade officially.
