How to Convert Points to Letter Grades
Converting your earned points into letter grades is a common need for students, teachers, and parents. Whether you are tracking your own academic progress, grading student work, or understanding transcript grades, knowing how to convert raw scores to letter grades helps you assess performance accurately.
The Points-to-Grade Formula
The formula is simple: Percentage = (Points Earned / Points Possible) x 100. Then use a grade scale to convert the percentage to a letter grade. For example, earning 172 out of 200 points: (172 / 200) x 100 = 86%, which is typically a B grade.
Standard US Grading Scale
The most common US grading scale is: 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%). Some institutions use variations, so always check your school specific scale.
Understanding Grade Boundaries
Grade boundaries determine where one letter grade ends and another begins. These boundaries are set by individual schools or departments and can vary significantly. A 92% might be an A- at one school but a B+ at another. Always refer to your institution official grading policy for precise cutoff points.
Why Point Conversion Matters
Understanding your percentage score helps you track progress toward grades, identify areas needing improvement, and set academic goals. It also helps teachers ensure consistent grading and provides students with clear feedback on their performance relative to course expectations.

Frequently Asked Questions
Divide the points you earned by the total possible points, multiply by 100 to get a percentage, then use a grade scale to find the letter grade. For example, 85 out of 100 = 85%, which is typically a B. Our calculator does this conversion instantly.
While scales vary by institution, common US grading scales are: 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%). Always check your school specific scale.
A passing grade is typically D (60-62%) or higher, though many programs require a C (73%) or better for major courses. Graduate programs usually require a B (83%) or higher. Check your institution requirements, as passing thresholds vary.
Our calculator uses the standard US grading scale and is accurate for percentage-to-letter-grade conversions. However, grading scales vary by institution. Always verify with your school official grade scale, as some schools use different cutoff percentages or plus/minus systems.
This calculator converts a single score to a letter grade. For weighted grades (where different assignments have different weights), you would calculate each weighted score separately, sum them, and then use this calculator to find the final letter grade. Our GPA calculator handles multi-course weighted calculations.
