How to calculate your semester GPA
Choose a maximum grade-point scale and enter the credits and numeric grade points for each course. Add rows when necessary. Grade points are the institutional values associated with the grades on your transcript; they are not percentage scores or points earned on an assignment.
A course name is optional, but both numeric fields are required on any row you use. Completely blank rows are ignored. Use positive credit values and points between zero and the scale maximum. The form supports up to 30 courses.
GPA formula: grade points weighted by credits
GPA = sum of (course grade points × course credits) ÷ sum of included credits. The numerator is often called quality points. Credit weighting gives a four-credit course twice the influence of a two-credit course at the same grade.
For example, three credits at 4.0 and four credits at 3.0 contribute 12 + 12 = 24 quality points. Divide by seven credits to obtain 3.4286, displayed as 3.429. Simply averaging 4.0 and 3.0 would give 3.5 and miss the different credit loads.
Using your own letter-grade conversion and scale
Use the grade-point values published by your institution. A common 4.0 table has A = 4, B = 3, C = 2, D = 1 and F = 0, but plus/minus values and A+ treatment vary. This tool does not impose a universal letter conversion.
The available maximum scales are 4.0, 4.3, 5.0 and 10.0. A different numeric scale can represent a credit-weighted average, but changing the maximum does not convert between countries or turn percentages into GPA.
Calculate cumulative GPA with previous semesters
Enter both your previous cumulative GPA and the GPA-counted credits behind it. The new cumulative value is (previous GPA × previous credits + current quality points) ÷ (previous credits + current included credits). Leave both prior fields blank for semester GPA only.
For a previous GPA of 3.2 over 30 credits, the prior quality points are 96. Adding the seven-credit example with 24 points produces 120 ÷ 37 = 3.2432. Averaging the old and new GPAs directly would not be correct.
Pass/fail, withdrawals and repeated courses
Include only courses and credits that your institution counts toward GPA. Pass/fail, withdrawals, incomplete courses, transfer credits and repeated courses can have special policies. A course excluded from GPA may still count toward graduation requirements.
Do not represent an excluded pass as zero points, because that would lower the calculated GPA. Remove the row instead. If a repeated grade replaces an older grade, adjust the prior totals using the institution’s policy before combining them.
Common GPA input errors
The most frequent error is entering 85 as grade points on a 4.0 scale. Another is using all earned credits as prior credits when some do not count toward GPA. Check your transcript’s GPA credit total rather than guessing.
Displayed values are rounded to three decimal places; official transcripts may truncate or round differently. The tool is useful for checking arithmetic, but it does not certify admissions eligibility or reproduce every institution’s academic policy.
GPA calculator FAQs
Can I convert a Spanish mark out of 10 to US GPA? Not with a universal formula. Use the receiving institution’s approved conversion. Can I enter an F? Enter its published numeric value, often zero, with the course’s GPA-counted credits.
Does a higher scale automatically add AP or honours weighting? No. Enter the weighted grade points only if your school’s policy uses them. Can I calculate several semesters? Combine their course rows, or use a prior cumulative value with its credits.
