Calculate your grade percentage by dividing points earned by total points. Instantly convert raw scores to percentages and letter grades.
Knowing your grade as a percentage is the most straightforward way to understand where you stand in any class. Whether you just got back a midterm, finished a homework set, or want to see your overall course standing, a grade percentage calculator turns your raw points into a clean, easy-to-read number.
This calculator takes the points you earned and the total points possible, then applies the simple formula: grade percentage equals points earned divided by total points, multiplied by 100. The result tells you exactly what share of the available marks you captured. From there, you can map the percentage to a letter grade using standard or custom thresholds.
Students, parents, and teachers all benefit from this tool. Students can check individual assignments or aggregate their scores across an entire semester. Teachers can quickly verify grade distributions, and parents can track their child's academic progress without waiting for report cards.
Manually dividing scores and converting to percentages is error-prone, especially when you're juggling multiple assignments and categories. This calculator does the math instantly and accurately. It's also useful for understanding what a raw score actually means — scoring 47 out of 55 might feel vague, but 85.5% is immediately meaningful. Use it to set targets, identify weak spots, and celebrate improvements.
Grade Percentage = (Points Earned ÷ Total Points) × 100 Example: 42 earned out of 50 total = (42 ÷ 50) × 100 = 84%
Result: 84.00%
You earned 42 points out of a possible 50. Dividing 42 by 50 gives 0.84, and multiplying by 100 converts that to 84%. On a standard grading scale, 84% corresponds to a B letter grade.
Grade percentages provide a universal way to compare performance across assignments, classes, and schools. A percentage normalizes scores to a 0–100 scale regardless of whether an assignment is worth 10 points, 50 points, or 200 points. This makes it easy to see at a glance how well you did.
Most US institutions use a standard scale: 90–100% earns an A, 80–89% a B, 70–79% a C, 60–69% a D, and below 60% is an F. Some schools use plus and minus modifiers, where 87–89% is a B+ and 90–92% is an A−. Always check your school's specific grading policy.
Once you know your current percentage in a class, you can calculate exactly how many points you need on remaining assignments to reach your target grade. This is especially powerful during finals season when every point counts. Combine this calculator with the Final Exam Grade Needed Calculator to build a concrete study plan.
Divide the total points you earned by the total points possible, then multiply by 100. For example, if you earned 85 out of 100, your grade is 85%. This works for any assignment, test, or overall class total.
Most schools consider 60% (D) as the minimum passing grade, though many programs require 70% (C) or higher. Graduate programs often require 80% (B) or above. Check your institution's specific requirements.
Standard US grading uses: A = 90–100%, B = 80–89%, C = 70–79%, D = 60–69%, F = below 60%. Some schools add plus/minus modifiers (e.g., B+ = 87–89%).
Yes, if all assignments are worth the same type of points. Simply add up all points earned across assignments and divide by all points possible. If categories have different weights, use a weighted grade calculator instead.
Extra credit increases your points earned without changing points possible, which raises your percentage. For example, earning 105 out of 100 gives you 105%, though most schools cap grades at 100% on transcripts.
Ask your instructor for the total points. If grades are letter-based, convert them to a numeric scale first (e.g., A = 95, B = 85) and use those values as your earned and total points.
Multiply the desired percentage by the total points and divide by 100. For example, to get 90% on a 50-point test, you need 50 × 0.90 = 45 points.
