Percentage to Letter Grade Calculator

How to Use the Calculator

Getting a result takes just a few quick steps:

1. Enter the percentage earned on a test, assignment, or course.
2. Click Calculate Grade to run the conversion.
3. View the result, which shows the letter grade based on a standard grading scale.

For example, entering 95 returns an A, entering 87 returns a B+, and entering 76 returns a C. The result updates instantly, so there's no waiting around for an answer.

Percentage to Letter Grade Conversion Chart

Here's a general grade chart showing how percentages typically map to letters and their rough GPA equivalents:

Keep in mind this chart reflects one common standard grading scale, actual cutoffs can vary between schools, colleges, and countries, so it's always worth checking a specific institution's policy.

US Grading Scale: Letter Grade Thresholds

Instead of a range, this shows the minimum percentage needed to reach each letter grade on the standard US A–F plus/minus scale, useful for quickly checking whether a score cleared the next threshold up.

Common Decimal Percentages — Letter Grade Reference

Scores rarely land on a clean whole number. Here's how some frequently seen decimal percentages convert on the standard scale:

The calculator above handles any decimal value automatically, so there's no need to round a score up or down before checking it.

How to Convert a Percentage to a Letter Grade by Hand

Converting a score by hand comes down to finding which range a percentage falls into on the grading scale being used. A few quick examples:

• 95% falls in the top range, so it becomes an A.
• 87% lands in the upper-middle range, earning a B+.
• 76% sits in the middle range, resulting in a C.

The exact letter grade always depends on which grading scale a school or instructor has adopted, since not every institution draws the lines in the same place.

Common Percentage to Letter Grade Scales

Most schools rely on a standard A–F scale, but plus/minus grading (A-, B+, C-, and so on) is common too, especially in colleges. Some institutions add extra nuance with an alternative grading system, while others keep things simple with straight letters and no modifiers. Because of these differences, it's worth checking a school's official grading policy before assuming a result applies everywhere.

Some students also compare results using other well-known tools, though scales still vary from one site to the next, always confirm against your own institution's official grading scale before relying on a single conversion.

Why the Same Score Can Mean Something Completely Different Across Countries

A 75% is a solid grade in one country and a top-tier score in another. Grading philosophy, not just the cutoff numbers, varies widely around the world:

Because grading philosophy differs this much, a percentage-to-letter-grade conversion is only ever accurate within the grading system it was designed for. Always check the official scale for the specific country or institution before comparing scores across borders.

Percentage to Letter Grade Examples

Here's a quick example run using a typical scale:

• 100% → A+
• 95% → A
• 90% → A-
• 85% → B
• 80% → B-
• 75% → C
• 70% → C-
• 65% → D
• 60% → D-

These results assume the standard scale used by the calculator above, a different scale could shift some of these letters slightly.

Percentage vs Letter Grade

A percentage grade shows precisely how many points were earned out of a possible total, while a letter grade groups that number into a broader category. Schools convert percentages into letters because they're easier to interpret at a glance and simpler to compare across different assignments. Teachers often work with the raw numerical grade when calculating scores, while students and parents tend to think in terms of the letter that summarizes performance.

GPA and Letter Grades

Letter grades connect directly to GPA, since each letter typically corresponds to a set number of grade points. An A might equal 4.0, a B roughly 3.0, and so on down the scale, a 3.5 GPA, for example, usually sits between a B+ and an A- average.

It's worth remembering that these scales differ from one school to another, so a score doesn't always convert to the same value everywhere. Anyone unsure how their school handles this should check their institution's official GPA scale directly.
