Letter Grade Calculator

EducationLast updated: August 17, 2026

At universities, end-of-term achievement is reported with letter grades rather than a score out of 100: AA marks the highest level of achievement and FF marks failure. Every letter grade has a grade point on the 4.0 scale (AA = 4.00, BA = 3.50 ... FF = 0.00), and the cumulative grade point average is computed from those grade points.

This calculator converts your grade out of 100 into a letter grade and a 4.0-scale grade point using the conversion table most widely applied by the Council of Higher Education, and it tells you whether you passed the course. The full conversion table appears below the result. Because your own university's regulations may define different bands, check your institution's table as well before relying on the result.

Current Letter Grade Bands and Grade Points

This calculator converts a grade out of 100 into a letter using the conversion table most widely applied by the Council of Higher Education. The table below summarizes which score band maps to which letter and 4.0-scale grade point.

Highest band
90 – 100
AA, grade point 4.00 on the 4.0 scale
Outright pass band
70 – 100
90+ AA (4.00), 85–89 BA (3.50), 80–84 BB (3.00), 75–79 CB (2.50), 70–74 CC (2.00)
Conditional pass band
60 – 69
65–69 DC (1.50), 60–64 DD (1.00); for it to count as a pass, the cumulative grade point average usually has to be above 2.00
Failing band
0 – 59
50–59 FD (0.50), 0–49 FF (0.00); in both cases the course has to be repeated
Grade point step between bands
0.50
Each letter step is worth 0.50 points on the 4.0 scale; the bands come in 5-point slices

Formula

90–100 → AA (4.00)   85–89 → BA (3.50)   80–84 → BB (3.00)
75–79  → CB (2.50)   70–74 → CC (2.00)   65–69 → DC (1.50)
60–64  → DD (1.00)   50–59 → FD (0.50)   0–49  → FF (0.00)

CC and above is an outright pass; DC and DD are a conditional pass at most universities (subject to a cumulative grade point average requirement); FD and FF count as failures.

How to Calculate

  1. Enter your grade out of 100 — your midterm-final average or your end-of-term achievement grade.
  2. Press Calculate to see your letter grade, your 4.0-scale grade point, and your pass status.
  3. Use the table below the result to review the letter and grade point for every score band.
  4. To work out a cumulative average, feed the grade point into the GPA calculator together with the credit value of the course.

Worked Examples

A grade right on the BA line

A student scoring 85 out of 100 falls in the 85–89 band: the letter grade is BA, the grade point is 3.50, and the course is an outright pass. One point lower (84) would have made it BB (3.00).

Letter grade: BA · Grade point (4.0 scale): 3.50 · Pass status: Pass

Passing with a CC

A score of 72 falls in the 70–74 band: the letter grade is CC and the grade point is 2.00. At most universities CC is an outright pass and no average requirement applies.

Letter grade: CC · Grade point (4.0 scale): 2.00 · Pass status: Pass

Failing with an FF

A score of 45 falls in the 0–49 band: the letter grade is FF, the grade point is 0.00, and the student fails the course. FD (0.50), the 50–59 band, also counts as a failure; the course has to be repeated.

Letter grade: FF · Grade point (4.0 scale): 0.00 · Pass status: Fail

Frequently Asked Questions

Are letter grades the same at every university?
No — and this is the most important caveat. The table used here is the conversion most widely applied by the Council of Higher Education, but each university senate may set its own score bands. At some universities the AA threshold is 88 or 92, and some use relative (curved) grading based on the class average instead of absolute grading. Check your university's education regulations for the definitive conversion.
Are DC and DD passing grades?
At most universities they are conditional passes: to count as having passed, your cumulative grade point average has to be above a set threshold, usually 2.00. If your average is low, you may be required to repeat a course in which you got DC or DD.
What is the difference between FD and FF?
Both are failing grades and both require the course to be repeated. FD (50–59) carries a grade point of 0.50, so it makes a small contribution to your average; FF (0–49) carries 0.00 and is the grade that drags an average down the most. Some universities do not use the FD band at all.
How is the cumulative grade point average calculated?
Each course's 4.0-scale grade point is multiplied by its credit value (ECTS or local credit), the products are summed, and the total is divided by the total credits. A student with BB (3.00) in a 3-credit course and AA (4.00) in a 2-credit course has an average of (3×3 + 2×4) / 5 = 3.40. Our GPA calculator does this for you automatically.
How is a 4.0-scale average converted to a grade out of 100?
The official conversion table of the Council of Higher Education is used; public institutions and many applications rely on it. For a rough idea you can multiply the 4.0-scale grade by 25 (3.00 becomes 75, for instance), but the official table departs somewhat from that linear multiplication; always use the official table for formal purposes.
How does curved (relative) grading affect the letter grade?
Under relative grading your letter grade is determined not by your absolute score but by the class mean and standard deviation. In an exam where the class average is low, 70 points may earn a BA, while in a course with a high average the same score may stay at CC. This calculator shows the absolute (fixed-band) conversion.
