Free GPA Calculator — Calculate Your Cumulative GPA Instantly

What the calculator does

The calculator accepts letter grades (A, B, C, etc.) or numeric grades, course credit hours, and groups courses by semester or term. The tool:

• Converts your grades to numeric equivalents on your chosen scale
• Weights each grade by credit hours (a 4-credit course counts more heavily than a 1-credit course)
• Calculates cumulative GPA across all courses entered
• Shows term GPA for each semester individually
• Allows you to recalculate instantly if you edit grades or add new courses

No login required, no data stored — it's a quick, free reference tool.

How to use the calculator

1. Select your grading scale. Most US institutions use 4.0; some use 4.3 or 5.0. International or specialized programs may use percentage-based scales (0–100).
2. Choose a semester or term to organize courses (optional, but helpful for tracking term GPA separately from cumulative).
3. Enter a course: course name (optional), letter or numeric grade, credit hours.
4. Add more courses. The calculator updates in real time as you enter grades.
5. View your GPA. Cumulative GPA updates automatically, and term GPA is shown for each semester you've entered.
6. Edit any entry. Change a grade, credit hour, or semester, and the GPA recalculates instantly.

Understanding letter-to-GPA conversion

The standard 4.0 scale maps letter grades as follows:

Different institutions may use slightly different scales. Check your school's official conversion if you're calculating toward a specific application (graduate school, transfer, professional licensing).

Weighted vs. unweighted GPA

Unweighted GPA treats all courses equally, regardless of credit hours. A 1-credit course counts the same as a 4-credit course. This is less common in college but sometimes used in high school.

Weighted GPA multiplies each grade by the course credit hours before averaging. A 4-credit course with an A (4.0) contributes more to your GPA than a 1-credit course with the same grade. Most colleges use weighted GPA because it reflects the actual academic load.

Example: If you take one 4-credit A course and one 1-credit A course:

• Unweighted: (4.0 + 4.0) ÷ 2 = 4.0
• Weighted: (4.0 × 4 + 4.0 × 1) ÷ (4 + 1) = 20 ÷ 5 = 4.0 (same in this case, but different if grades vary)

The calculator uses weighted GPA by default, which is standard for most institutions.

Cumulative vs. term GPA

Cumulative GPA is your average across all courses you've taken, from the first semester to the most recent. This is the GPA most institutions report on official transcripts and the one used for academic standing, scholarships, and applications.

Term GPA is your average for a single semester or term. It shows your performance in that specific period and can be a useful indicator of improvement or decline over time.

The calculator displays both: term GPA for each semester you enter, and cumulative GPA across all semesters combined.

Common grading scales

Most US institutions use a 4.0 scale, but some variants exist:

4.0 Scale — The standard in most US high schools and colleges. Highest is 4.0, lowest is 0.0.

4.3 Scale — Used by some institutions to differentiate A+ grades. A+ is 4.3, A is 4.0, A- is 3.7, etc.

5.0 Scale — Used by some schools to weight honors or advanced courses. An A in an honors course might be 5.0, while an A in a standard course is 4.0.

Percentage Scale — Some institutions or countries use percentage grades (0–100). An A might be 90–100, B is 80–89, etc. The calculator can convert these to 4.0 if you enter the percentage and select the percentage scale option.

Weighted Scale (High School) — Some high schools weight honors and AP courses more heavily. Standard courses are on the 4.0 scale, honors courses add 0.5 (making an A in honors worth 4.5), and AP courses add 1.0 (making an A worth 5.0). The calculator lets you set custom weights if your school uses this system.

Consult your official transcript or school's registrar office to confirm which scale your institution uses.

Using GPA in applications

Graduate School — Most graduate programs require a GPA of 3.0 or higher for consideration. Cumulative GPA is the standard metric, though some programs also consider GPA in major or upper-level courses.

Transfer Applications — When transferring schools, many institutions require a minimum GPA for admission. A 3.0 is common; competitive schools may require 3.5 or higher.

Professional Licensing — Some professional boards (law, medicine, accounting) require a minimum GPA for exam eligibility or licensing. Check your field's requirements.

Scholarships and Academic Standing — Merit scholarships often require a minimum GPA. Academic probation is typically triggered by GPA below 2.0.

Employment — Some employers, particularly for entry-level positions in competitive fields, ask for minimum GPA (usually 3.0) as a screening criterion.

GPA and your academic record

Your official GPA is recorded on your academic transcript, which is issued by your school's registrar. If you need to provide your GPA for an application, request an official transcript from your registrar rather than relying on your own calculation. Official transcripts are verified and carry the authority of the institution.

The DiplomaCraft GPA calculator is a tool for learning and personal reference — useful for understanding how your grades combine and estimating your cumulative average. For official purposes (applications, licensing, employment verification), use your official transcript.
