GPA Calculator
This GPA calculator converts up to six course letter grades — with full plus/minus granularity on the standard 4.0 scale — into a semester GPA. It assumes equal credit hours per course, which fits most high-school and many college schedules. Enter each course’s letter grade and get your GPA plus total credits and grade points in one view.

How it was calculated
- Grade points: A=4.0, B+=3.3, A−=3.7, B=3.0, C+=2.3, A=4.0.
- GPA: 20.3 ÷ 6 = 3.383.
How it works
Each letter grade maps to grade points on the standard 4.0 scale: A/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.
With equal credit hours, the GPA is the plain mean of the grade points: add them up and divide by the number of courses. (Equal credits cancel out of the weighted formula.)
Total grade points — the numerator colleges actually track — is the sum of grade points times the per-course credit hours.
Worked examples
A, B+, A−, B, C+, A (3 credits each)
Points: 4.0 + 3.3 + 3.7 + 3.0 + 2.3 + 4.0 = 20.3. GPA = 20.3 ÷ 6 = 3.383. Total: 18 credit hours and 60.9 grade points.
Straight B average, 4 credits each
Six B grades = 6 × 3.0 = 18.0 points; 18.0 ÷ 6 = 3.000 GPA. Total: 24 credit hours and 72.0 grade points — a clean 3.0 semester.
How to measure
- Enter the final letter grade per course as it appears on your transcript — not the percent that produced it.
- Use the plus/minus variant your school reports; if your school only uses straight letters, the High School GPA Calculator is simpler.
- Confirm every course really carries the same credits before trusting this; labs and half-credit courses break the equal-credit assumption.
- For repeated courses, check your school’s policy — many replace the old grade rather than averaging both.
Assumptions & limitations
Planning estimate
- All courses are assumed to carry equal credit hours. For varying credits, use the College GPA Calculator, which weights each course properly.
- The standard 4.0 plus/minus point table is used; some schools use different values (e.g. A+ = 4.3) or no plus/minus at all.
- Pass/fail, audit, and incomplete courses should be excluded — they carry no grade points in standard GPA math.
- This computes a semester GPA from one term’s courses; cumulative GPA across terms needs the CGPA Calculator.
Frequently asked questions
Each letter grade converts to points (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0, with plus/minus steps in between), and the GPA is the average of those points — weighted by credit hours when credits differ. With equal credits, it is simply the mean of the six grade-point values.
Context matters: a 3.0 is the common cutoff for "good academic standing" and many scholarships, 3.5+ is typical for honors programs, and 3.7+ is competitive for selective graduate schools. Employers and programs also weigh trends — a rising GPA beats a flat one.
No. The point values for plus/minus grades vary, some schools cap at 4.0 with no A+ bonus, and others use entirely different scales (5.0 weighted, 100-point, or 10-point systems). Always check your institution’s catalog for its official table.
The usual culprits: unequal credit hours (use the College GPA Calculator), a different plus/minus table, repeated-course replacement rules, or excluded pass/fail courses. Match those inputs and the numbers should agree.
On the standard unweighted 4.0 scale, no — 4.0 is the ceiling. Weighted scales (honors/AP bonuses) do exceed it, which is what the Weighted GPA Calculator handles on a 5.0 scale.
