How GPA Is Calculated

GPA (Grade Point Average) is the weighted average of your grade points across all courses. Each letter grade maps to a numeric value, on a 4.0 scale, A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. Multiply each course's grade points by its credit hours, sum all those products, then divide by total credit hours.

Example: Math (A, 3 credits) = 12 points. English (B, 4 credits) = 12 points. Total = 24 ÷ 7 credits = 3.43 GPA.

Weighted vs. unweighted: A 5.0 scale gives extra points for advanced courses (AP, IB, honors). An unweighted 4.0 scale treats all courses equally. Check your school's policy before selecting a scale.

4.0, 5.0 & Percentage Scales Explained

4.0 Scale (Unweighted)

A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. This is the standard scale used by most US high schools and colleges for regular-level courses. Enter each course's score as a percentage; the calculator maps it to the matching letter grade automatically (90+ = A, 80-89 = B, 70-79 = C, 60-69 = D, below 60 = F) before computing points.

5.0 Scale (Weighted)

A = 5.0, B = 4.0, C = 3.0, D = 2.0, F = 0.0. Schools apply this scale to honors, AP, or IB courses to reward the added difficulty. The same percentage-to-letter mapping is used, only the point values per letter are one full point higher across the board.

Percentage Scale

Some institutions report GPA directly on a 0-100 scale rather than converting to letter grades and points. Selecting this mode skips the letter-grade conversion entirely: your entered percentages are weighted by credit hours and averaged directly, so a 92% in a 3-credit course and an 85% in a 4-credit course blend into a single weighted percentage.

Common Use Cases

College applications: Calculate your cumulative GPA across every semester completed so far to include on applications or scholarship forms that ask for an unofficial GPA.
Transferring schools: Recompute your GPA on the new institution's scale (4.0 vs 5.0) to see how your transcript will translate before you commit to a transfer.
Mid-semester planning: Enter your grades so far alongside projected grades for remaining courses to see what GPA you are on track for by the end of the term.
Scholarship and academic standing checks: Many scholarships and honors programs require a minimum cumulative GPA; check your current standing before a renewal deadline.

Planning a Target GPA

A common question is not "what is my GPA now" but "what GPA do I need in future courses to reach a specific cumulative target." The math works in reverse from the standard formula: multiply your target GPA by your total credits once remaining courses are included, subtract the grade points you have already earned, then divide by the remaining credits.

Worked example: you currently hold a 3.2 GPA across 60 credits (192 grade points), and want to reach a 3.5 cumulative GPA by the time you finish 90 total credits. Target points needed = 3.5 × 90 = 315. Points still needed = 315 − 192 = 123. Remaining credits = 30. Required average GPA on those remaining 30 credits = 123 ÷ 30 = 4.10, which is above a 4.0 scale's maximum for unweighted courses, meaning the target is not reachable without weighted or extra-credit coursework.

This calculator does not automate that reverse calculation, but you can run it yourself with any current GPA and credit total from the results above, or test scenarios by entering hypothetical future courses alongside your completed ones to see the resulting cumulative GPA directly.

Check Your School's Official Scale First

GPA policies vary significantly between institutions. Some schools use plus/minus grading (A-, B+) with intermediate point values like 3.7 or 3.3, some cap weighted courses at a maximum GPA regardless of scale, and some exclude pass/fail or withdrawn courses entirely from the calculation, while others average every attempt of a repeated course instead of using only the latest grade. This calculator uses the standard whole-letter 4.0/5.0 conversion described above; always confirm against your registrar's official policy before submitting a GPA on an application.

Frequently Asked Questions

How do I calculate my GPA?▾
GPA = Total Grade Points ÷ Total Credits. Each grade earns points (A=4.0, B=3.0, C=2.0, D=1.0, F=0.0 on 4.0 scale). Multiply each course's grade points by its credits, sum them, then divide by total credits. This calculator does the math automatically.
What is the difference between 4.0 and 5.0 scales?▾
4.0 scale: A=4.0, B=3.0, C=2.0, D=1.0, F=0.0. 5.0 scale: A=5.0, B=4.0, C=3.0, D=2.0, F=0.0. Some high schools and colleges use 5.0 for weighted courses (honors, AP). Check which scale your institution uses.
How do I calculate GPA from percentage?▾
Convert percentage to letter grade: 90-100%=A, 80-89%=B, 70-79%=C, 60-69%=D, below 60%=F. Then calculate using letter grade points. Some institutions use direct percentage GPA (sum of percentages ÷ number of courses).
Do all courses count toward GPA?▾
Usually yes, but policies vary. Pass/fail courses typically don't affect GPA. Repeated courses may use only the latest grade or average all attempts. Check your school's policy. This calculator includes all courses you enter.
What is a good GPA?▾
It depends: 3.0+ is B average (good), 3.5+ is A- range (very good), 3.7+ is A range (excellent). Ivy League/grad schools often want 3.7+. Some jobs have minimum GPA requirements. Context matters by school and program difficulty.
How do weighted courses affect GPA?▾
Weighted courses (honors, AP, IB) may add 0.5-1.0 point to grade points. On a 5.0 scale, A in AP = 5.0 vs regular A = 4.0. This boosts GPA for advanced coursework. Use the 5.0 scale option if your school weights courses.
Can I calculate cumulative GPA?▾
Yes. Enter all courses from all semesters. The calculator totals all grade points and credits, giving your overall cumulative GPA. For individual semesters, enter only that semester's courses.
What GPA do I need in future courses to hit a target GPA?▾
Multiply your target GPA by your total credits (current plus remaining) to get the total grade points you need. Subtract the grade points you already have. Divide the result by your remaining credits to get the average GPA those future courses must earn. See the worked example in the "Planning a Target GPA" section above for the full calculation.
What is the difference between semester GPA and cumulative GPA?▾
Semester GPA covers only the courses taken in one term. Cumulative GPA covers every course from every term completed so far, weighted by each course's credit hours. Transcripts and academic standing checks almost always use cumulative GPA, while a single semester's GPA is mainly useful for tracking term-to-term progress.
