GPA Calculator

GPA (Grade Point Average) converts your letter grades into a single number, weighted by how many credit hours each course is worth. The formula is: GPA = (grade points × credit hours, summed across courses) ÷ total credit hours. A 4-credit A− counts more toward your GPA than a 1-credit A− because it carries more weight.

On the most common U.S. 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 = 0.0. Some schools award A+ a 4.3 instead of capping it at 4.0 — check your registrar's page if your transcript looks slightly different from this calculator.

Unweighted GPA treats every class the same regardless of difficulty — an A is a 4.0 whether it's a regular class or an AP class. Weighted GPA adds bonus points for higher-difficulty courses, commonly +0.5 for Honors and +1.0 for AP/IB/college-level, which is why a strong high school transcript can show a weighted GPA above 4.0.

This calculator uses the most common convention: +0.5 grade points for Honors courses and +1.0 for AP, IB, or dual-enrollment college courses, applied to every passing grade (F stays at 0.0 either way). Some schools use different bonuses or cap the weighted scale at 5.0 — treat this as a close estimate and confirm the exact policy with your school counselor.

Check "Include previous GPA," then enter your current cumulative GPA and total credit hours earned so far. The calculator combines those with the new courses you've entered into one cumulative GPA — the same method registrars use, and more accurate than averaging semester GPAs together directly.

It depends on context, but as general benchmarks: 3.5+ is typically Dean's List territory, 3.0+ satisfies most scholarship and grad school minimums, 2.0 is the usual floor before academic probation, and dropping below that risks financial aid eligibility at many schools. Competitive graduate programs often expect 3.5+.

Match your percentage to the closest letter grade in the scale table above (93–100% is typically an A, 90–92% an A−, and so on), then use that letter grade in the calculator. Schools vary slightly in where they draw the line between grades, so check your syllabus if you're on the border.

Yes. High schoolers get the most value from the Honors/AP weighting option, since it mirrors how most high school transcripts are actually built. Middle schoolers don't usually have an official GPA yet, but the calculator is a useful preview of how letter grades and credit hours will combine once GPA starts counting.

Yes — that's expected. A student with several A's in AP or IB classes can land a weighted GPA of 4.3, 4.5, or higher, since each weighted A is worth more than 4.0 grade points. Colleges are aware of this and often recalculate applicants' GPAs on an unweighted scale for comparison, which is why this calculator shows both numbers.

Yes — it's free, requires no signup, and every calculation happens in your browser. The math follows the standard credit-weighted GPA formula used by most U.S. high schools and colleges, but always treat your official transcript or registrar's calculation as the authoritative number for anything that matters, like applications, scholarships, or academic standing.
