What Is GPA?
GPA (Grade Point Average) is a number that summarizes your academic performance across courses. Each letter grade is assigned a numeric value (e.g. A = 4.0, B = 3.0), and your GPA is the average of those values weighted by credit hours. Many US schools use a 4.0 scale where A and A+ = 4.0, A- = 3.7, and so on; some use a 4.3 scale where A+ = 4.3. Our calculator supports both. High schools and colleges use GPA for admissions, scholarships, and academic standing.
How GPA Calculation Works
The formula is: GPA = Sum(grade points × credit hours) / Sum(credit hours). For each course, multiply the grade point (e.g. 4.0 for an A, or 4.3 for A+ on a 4.3 scale) by the number of credits to get quality points. Add all quality points, then divide by total credits. Example: an A (4.0) in a 3-credit course and a B (3.0) in a 4-credit course give (4×3 + 3×4) / 7 = 24/7 ≈ 3.43 GPA.
GPA Scales: 4.0 vs 4.3
On the 4.0 scale, A+ and A both equal 4.0; 97–100% maps to A+ (4.0), 93–96% to A (4.0), and 90–92% to A- (3.7). On the 4.3 scale, A+ = 4.3 (often used for 97–100%), while A = 4.0 and A- = 3.7 are unchanged. Our tool lets you switch between 4.0 and 4.3 and converts percentage inputs to the correct grade point for the selected scale.

Semester vs Cumulative GPA
Semester GPA is the average for a single term. Cumulative GPA includes all prior terms plus the current one. Switch to "Cumulative" and enter your previous GPA and total credits to see your updated overall GPA. Use the Target GPA Simulator to find the grade you need in an upcoming course to hit a target GPA.
Tips to Improve GPA
Focus on higher-credit courses first—they affect your GPA more. Use the Target GPA Simulator to see required grades. Track progress with this semester GPA calculator before finals. For other planning tools, try our Age Calculator.
Why a Browser-Based GPA Calculator Is Safer
A browser-based GPA calculator runs only on your device. Your grades and course names are never uploaded, so there’s no privacy risk. Results are instant, and the tool works offline after the page loads. No accounts, tracking, or ads—ideal for a fast, accurate 4.0 or 4.3 GPA calculator without sharing data.
Frequently Asked Questions
How is GPA calculated?
GPA = Sum(grade points × credit hours) / Sum(credit hours). Each letter grade has a point value (A = 4.0, B = 3.0, etc.); multiply by credits for each course, add, then divide by total credits.
What is a 4.0 GPA scale?
The standard US scale where A/A+ = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, down to F = 0.0. A 4.3 scale gives A+ = 4.3; our calculator supports both.
What is the difference between semester and cumulative GPA?
Semester GPA is for one term. Cumulative GPA includes all previous coursework plus the current term, weighted by credits.
Is this GPA calculator accurate?
Yes. We use the standard 4.0/4.3 scale and the correct weighted formula. Always confirm with your school’s policy for minor variations.
Is GPA calculated differently by schools?
Yes. Most US schools use 4.0; some use 4.3 (A+ = 4.3) or 5.0. Percentage cutoffs (e.g. 90–92% for A-) can also vary. Our tool supports 4.0 and 4.3—check your school’s policy for exact mapping.
