How is GPA calculated from a transcript?

Each grade is converted to grade points on the 4.0 scale, multiplied by the course's credit hours, and summed. Dividing the total grade points by the total credit hours gives the credit-weighted cumulative GPA.

Which letter grades are supported?

The standard A through F scale with plus and minus modifiers: A is 4.0, A- is 3.7, B+ is 3.3, B is 3.0, and so on down to F at 0.0. An A+ is treated as 4.0 since most US schools cap GPA at 4.0.

Why weight by credit hours?

A 4-credit course should influence your GPA more than a 1-credit course. Multiplying each grade point by its credit hours before averaging gives the correct credit-weighted GPA that your registrar uses.

What format should each line use?

Put the grade first, then the credit hours, separated by a space or comma, like 'A- 3' or 'C+, 4'. Lines the tool cannot parse are skipped and listed so you can fix them.

Are pass/fail courses included?

No. Pass/fail and credit/no-credit courses do not carry grade points and are excluded from GPA at most schools. Leave them out of your list, or the tool will skip any grade it does not recognize.

When you just need a fast GPA from a list of grades, this calculator does it without forcing you into a row-by-row form. Paste your courses as a grade and a credit count per line and it returns your credit-weighted cumulative GPA on the standard 4.0 scale.

How it works

Each line is parsed into a letter grade and a credit value. The letter maps to a grade point, which is then weighted by credits:

A  = 4.0   A- = 3.7
B+ = 3.3   B  = 3.0   B- = 2.7
C+ = 2.3   C  = 2.0   C- = 1.7
D+ = 1.3   D  = 1.0   D- = 0.7
F  = 0.0

GPA = sum(grade point * credits) / sum(credits)

Lines that do not contain a recognizable grade and a number are skipped and shown back to you so you can correct typos.

Why credit weighting matters

A simple average of grades treats a 1-credit seminar the same as a 4-credit lab course. That is not how GPAs work. Each course’s grade is multiplied by its credit count before summing, which means a B in a 4-credit course has four times as much influence as a B in a 1-credit course. This is the formula your registrar uses and the one that appears on your official transcript.

The practical implication: if you are trying to raise your GPA, your effort is better spent on high-credit courses. An A in a 4-credit class adds 16.0 quality points; an A in a 1-credit class adds 4.0. The credit-weighted formula makes that arithmetic visible.

Common mistakes to avoid

Including pass/fail grades. Courses graded P/F or CR/NC earn credits but no grade points and are excluded from GPA at virtually every institution. Including them in the list will cause the calculator to skip them (since “P” is not a recognized letter grade), which is correct. If you see a line flagged as unrecognized, check whether it is a pass/fail course.

Using wrong repeat policies. If you repeated a course, most schools count only the second attempt, or only the higher grade, in the GPA. Do not include both grades for the same course — use only the one your institution counts.

Mixing scales. Some institutions use a 4.33 scale where A+ = 4.33, or a 5.0 scale. This calculator uses the standard US 4.0 scale where A+ = 4.0 (capped). If your school uses a different scale, the result will not match your official GPA.

Worked example

Three courses — A 3, B+ 4, A- 3 — work out as follows:

A (4.0) × 3 credits = 12.0 quality points
B+ (3.3) × 4 credits = 13.2 quality points
A- (3.7) × 3 credits = 11.1 quality points
Total: 36.3 quality points over 10 credits
GPA = 36.3 / 10 = 3.63

Now add one more line: C 4. That adds 2.0 × 4 = 8.0 quality points over 4 more credits. New total: 44.3 / 14 = 3.16. A single 4-credit C drops the GPA by nearly 0.5 points — which is why high-credit difficult courses require more consideration when choosing how to spend study time.

Use a consistent separator (space or comma), and remember to leave out pass/fail courses since they carry no grade points.
