How to Convert a Percentage to a Letter Grade
A letter grade turns a raw score into a single symbol (A+ to F) that transcripts, scholarships and universities read the same way everywhere. This percentage to letter grade calculator maps your score to the standard US plus/minus scale and its 4.0 GPA in one step.
Step 1 — Get your percentage
If you have raw marks, first divide by the total and multiply by 100: Percentage = (Marks ÷ Total) × 100. So 420 out of 500 is (420 ÷ 500) × 100 = 84%. The Marks ÷ Total mode above does this for any total automatically.
Step 2 — Match it to the grade band
Find the band your percentage falls in. 84% sits in the 83–86% band, which is a B (3.0 GPA). A 76% is a C (2.0), and 91% is an A- (3.7).
Step 3 — Handle borderline scores
Decimals like 89.5% or 79.9% confuse students most. Some schools round to the nearest whole number, others don't. This tool uses exact cutoffs with no rounding, so you see the true band your score lands in. Applying abroad? Convert across countries with our Global Grade Converter.

Frequently Asked Questions
What letter grade is 75%?
On the standard US plus/minus scale, 75% is a C (2.0 GPA) — the 73–76% band. On a simple A–F scale it is also a C (70–79%). It passes at most colleges, though some majors need a C or higher to count the course.
What letter grade is 85%?
85% is a B (3.0 GPA), sitting in the 83–86% band on the plus/minus scale. On a simple scale it is still a solid B (80–89%).
What letter grade is 90%?
90% is an A- (3.7 GPA) on the detailed plus/minus scale (90–92%). You need 93%+ for a full A (4.0). Some schools use a flat 90% = A cutoff, so always check your institution's policy.
Is 70% a passing grade in college?
Yes. 70% is a C- (1.7 GPA) and passes at most undergraduate programs. But passing isn't always enough — some courses require a C (73%+) or higher to count toward your major.
How do I convert marks out of 500 into a letter grade?
Divide marks by the total and multiply by 100, then match the percentage to the scale. Example: 380 ÷ 500 × 100 = 76%, which is a C (2.0 GPA). Use the Marks ÷ Total mode above to do it automatically for any total.
Does an A+ give more than a 4.0 GPA?
At most colleges, no — an A+ is recorded as 4.0, the same as an A. A few schools assign 4.3 for an A+, which can lift a weighted GPA slightly above 4.0, but the standard unweighted ceiling is 4.0.
What is the difference between weighted and unweighted GPA?
An unweighted GPA (what this tool shows) scores every course on a 0–4.0 scale regardless of difficulty. A weighted GPA adds bonus points for Honors, AP or IB courses — often +0.5 or +1.0 — allowing a GPA above 4.0. Admissions offices often recalculate to unweighted for fair comparison.
