What this tool does
Computes a grade point average from a list of courses. For each course you pick a letter grade and enter its credit hours; the tool converts each grade to points on the standard 4.0 scale (A and A+ = 4.0 down to F = 0.0), weights each grade by its credit hours, and divides the total quality points by the total credits. The GPA updates live as you type, and everything runs locally in your browser, so nothing you enter is uploaded.
How to use it
Add one row per course. The course name is optional and only helps you keep track. Choose the letter grade from the dropdown and type the credit hours (usually 1 to 5). Use Add course for more rows and Remove to drop one. Example: an A (4.0) worth 3 credits plus a B (3.0) worth 3 credits gives 21 quality points over 6 credits, or a 3.50 GPA. The result and total credits appear instantly.
Common use cases
- Estimating a semester or term GPA before grades are official.
- Checking whether you are on track for a scholarship or honors threshold.
- Modeling what grade you need in a remaining course to hit a target GPA.
- Turning a transcript of letter grades into a single number for an application.
- Comparing course-load scenarios when planning next term.
Common pitfalls
- Scale differences. Some schools use a 4.3 top for A+, quarter credits, or different plus/minus points. This tool uses the common 4.0 scale, so confirm your school policy if the exact number matters.
- Pass/fail and withdrawals. These usually do not carry grade points. Leave them out, or set their credit hours to zero so they are ignored.
- High-school weighted GPA. Honors and AP bonuses (like a 5.0 for an A) are not applied here. This is the unweighted 4.0 scale, weighted only by credits.
- Rounding. The displayed GPA is rounded to two decimals, which can differ slightly from a registrar that rounds to a different precision.
Frequently asked questions
- How is GPA calculated on a 4.0 scale?
- Each letter grade maps to a grade point: A and A+ are 4.0, A- is 3.7, B+ is 3.3, B is 3.0, and so on down to F at 0.0. Multiply each course grade point by its credit hours to get quality points, add up the quality points across all courses, then divide by the total credit hours. The result is the credit-weighted grade point average, rounded here to two decimals.
- What is the difference between weighted and unweighted GPA?
- This tool computes a credit-weighted GPA, which means a 4-credit course counts twice as much as a 2-credit course. That is the standard college method. A separate idea, also called weighted GPA in high schools, gives extra points for honors or AP classes (for example a 5.0 for an A in an AP course). This calculator does not add that honors bonus; it uses the plain 4.0 scale weighted only by credit hours.
- What grade points does each letter map to?
- On the standard 4.0 scale used here: A+ and A are 4.0, A- is 3.7, B+ is 3.3, B is 3.0, B- is 2.7, C+ is 2.3, C is 2.0, C- is 1.7, D+ is 1.3, D is 1.0, D- is 0.7, and F is 0.0. Some schools cap A+ at 4.0 (as this tool does), while others award 4.3; check the policy at your school if the exact top value matters.
- How do I handle pass/fail or withdrawn courses?
- Most schools leave pass/fail, credit/no-credit, and withdrawn courses out of the GPA entirely, even though they may still appear on a transcript. To match that, simply do not add those courses as rows, or set their credit hours to zero so they are ignored. Only letter-graded courses that carry grade points belong in the calculation.
- How does retaking a course affect my GPA?
- Grade replacement policies vary. Many schools count only the newer attempt once a course is repeated, while others average both attempts or keep both in the GPA. If your school replaces the old grade, enter only the new attempt here. If it averages them, enter both as separate rows. Check the repeat policy where you study before you rely on the number.
- Why does my calculated GPA differ from the one on my transcript?
- Common reasons include plus/minus rules that differ from the standard 4.0 scale, an A+ worth 4.3 instead of 4.0, quarter versus semester credit weighting, courses excluded for pass/fail or transfer, and rounding at a different number of decimals. This tool uses a widely used default; your registrar is the authority for your official GPA.
