Grade Calculator
Find your letter grade from a percentage score.
How it's calculated
This calculator maps a percentage score to a letter grade using a standard scale: 90% and above → A+ (Excellent) 80-89% → A (Very Good) 70-79% → B (Good) 60-69% → C (Satisfactory) 50-59% → D (Pass) Below 50% → F (Fail) If you have raw marks instead of a percentage, use our Percentage Calculator first to convert them.
Worked example
You scored 76% on an exam. 76% falls in the 70-79% range, so the grade is B (Good).
Frequently asked questions
- What grading scale does this use?
- A standard 6-tier scale from F to A+, based on percentage thresholds (90/80/70/60/50). If your institution uses a different scale, use the percentage as a general reference rather than an exact match.
- I have marks, not a percentage — what do I do?
- Use the Percentage Calculator to convert your obtained/total marks into a percentage first, then enter that percentage here.
- Does this account for grade curving or bonus marks?
- No — enter your final percentage after any curving or bonus adjustments have already been applied.
