How GPA Is Calculated
The formula is For each course, grade points = grade value ร credits. Sum all grade points, then divide by total credits. Example: B (3.0) in 4 credits = 12 points; A (4.0) in 3 credits = 12 points. Total 24 รท 7 credits โ 3.43 GPA. On an extended scale, A+ can count as 4.33, so your GPA can sit slightly above 4.0โcheck your schoolโs policy.
4.0 vs 5.0 Scale
The 4.0 scale is standard: A=4, B=3, C=2, D=1, F=0, with plus/minus (e.g. Aโ = 3.7, B+ = 3.3). The 5.0 weighted scale adds points for honors, AP, or IBโan A might count as 5.0. High schools often report weighted GPA; colleges may recalculate to unweighted 4.0 for admissions. Our calculator supports both so you can match your schoolโs system.
Grade Replacement for Retakes
At many schools, if you retake a class, the new grade replaces the old one in your GPAโyou donโt average the two. Some schools average both attempts or limit how many replacements count. Your institutionโs catalog or registrar is the source of truth.
GPA Calculator FAQ
? How is GPA calculated?
Your grade point average is . For each course, multiply the grade value (e.g. A = 4.0, B = 3.0) by the credits; sum those products, then divide by total credits. Example: a B in a 4-credit class and an A in a 3-credit class give (4ร3 + 3ร4) รท 7 = 24 รท 7 โ 3.43.
? What is the difference between 4.0 and 5.0 GPA scale?
The 4.0 scale is the usual letter-grade system (A through F with plus/minus). The 5.0 weighted scale gives extra points for honors, AP, or IBโso an A in an AP class can count as 5.0. Plenty of high schools report weighted GPA; colleges often strip it back to unweighted 4.0 for comparison.
? Do credits affect GPA?
Yes. Credits are the weight. A 4-credit course moves your GPA more than a 1-credit one. An A in 1 credit adds less than a B in 4 credits, so that tough 4-credit lab matters more than an easy 1-credit elective.
? What happens when I retake a class?
It depends on the school. Many use grade replacement: the new grade replaces the old one. Others average both attempts or cap how many retakes count. Your catalog or registrar has the exact policy.
? How do I raise my GPA?
Earn more credits at higher grades. Use the Target Calculator here: plug in the GPA you want and how many credits you have left; it shows the average you need in those remaining courses. Retaking a low grade can help if your school replaces it; so can adding strong credits to dilute older ones.
