Grade Calculator

What the Grade Calculator does

The Grade Calculator converts a percentage score into a letter grade using a standard grading scale, giving you a quick read on where a score lands without needing to look up a grading chart.

How to use it

1. Enter the score as a percentage.
2. The corresponding letter grade appears based on standard grading bands.

Common uses

• Checking what letter grade a percentage score converts to on a standard scale.
• Estimating a final grade needed on a remaining assignment to reach a target overall grade.
• Comparing a percentage score against a different institution's grading scale.
• Quickly interpreting a numeric test score without a printed grading chart on hand.
• Helping students understand grade boundaries when reviewing returned assignments.

Good to know

Grading scales vary meaningfully between schools, countries, and even individual courses — a 75% might be a B in one system and a C in another — so treat the letter grade shown here as based on a common standard scale, and always confirm against your specific institution's official grading policy for anything that counts toward a transcript.

Grading scale boundaries are one of the more inconsistent things across educational institutions — even within the same country, one university's B+ cutoff might be another's A- cutoff, and international programs often use entirely different scales altogether. This is especially worth double-checking for anything that matters for a transcript, scholarship eligibility, or GPA calculation, since a generic scale won't necessarily match your specific institution's official policy.
