Weighted Grade Calculator

Grade Calculator

Enter your scores and category weights to see your current weighted course grade and letter grade. Leave a category blank (like an upcoming final) to grade what you've completed so far.

How Weighted Grades Are Calculated (Worked Example)

A weighted grade is the sum of each category's score times its weight. Suppose your syllabus says homework 20%, quizzes 20%, midterm 25%, final 35%, and your scores so far are homework 92%, quizzes 85%, midterm 78%:

0.20×92 + 0.20×85 + 0.25×78 = 18.4 + 17.0 + 19.5 = 54.9 weighted points out of the 65% graded so far → current grade 54.9 ÷ 0.65 = 84.5% (B). The final exam's 35% is still open: a 95 on the final lands you at 88.2% (B+), while a 70 drops you to 79.4% (C+).

Letter Grade Scale (US Standard with Plus/Minus)

LetterPercentageGPA points
A93–100%4.0
A-90–92%3.7
B+87–89%3.3
B83–86%3.0
B-80–82%2.7
C+77–79%2.3
C73–76%2.0
C-70–72%1.7
D+67–69%1.3
D63–66%1.0
D-60–62%0.7
FBelow 60%0.0

Scales vary by school — some courses use straight cutoffs (A ≥ 90, B ≥ 80) with no plus/minus. GPA points feed into your cumulative GPA; see our GPA calculator.

Three Grading Systems You'll Meet

  • Weighted categories (this calculator) — each category has a syllabus weight; most college courses work this way.
  • Total points — everything goes into one pool; your grade is points earned ÷ points possible. Enter it here as one category at 100% weight.
  • Drop-lowest rules — many instructors drop the lowest quiz or homework before averaging. Recompute the category average without the dropped score, then enter that average.

Frequently Asked Questions

How do I calculate my grade with weighted categories?
Multiply each category's percentage score by its weight, add the products, and divide by the total weight. Example: homework 92% × 20 + quizzes 85% × 20 + midterm 78% × 25 = 18.4 + 17 + 19.5 = 54.9 out of 65 weight = 84.5% — a B.
What grade do I have if the final exam hasn't happened yet?
Instructors compute your current grade from only the completed categories, re-scaled to 100%. If 65% of the course is graded and you've earned 54.9 weighted points, your current grade is 54.9 ÷ 0.65 = 84.5%. Enter your syllabus categories and leave the final blank to see this number.
What percentage is an A, B, C, or D?
On the most common US scale: A is 93–100, 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, and below 60 is an F. Individual syllabi can differ — some courses use straight 10-point cutoffs without plus/minus.
What's the difference between weighted and unweighted (points-based) grading?
In weighted grading, each category has a fixed share of the final grade regardless of how many points it contains — a 10-point quiz category worth 20% counts the same as a 200-point exam category worth 20%. In points-based grading, your grade is simply total points earned ÷ total points possible. Check your syllabus for which system your course uses.
Can I use points instead of percentages?
Yes — enter points earned in Score and points possible in Out of (for example 45 out of 50). The calculator converts each category to a percentage before applying weights, so you can mix points-based and percentage categories freely.
How much will my final exam change my grade?
The final's impact equals its weight. With a 35% final and an 84.5% current grade, scoring 95 on the final gives 0.65 × 84.5 + 0.35 × 95 = 88.2% (B+), while scoring 70 gives 79.4% (C+). To find the score you need for a target grade, use our Final Grade Calculator.
