Calculate Your Weighted GPA
Enter up to twelve courses. Use letter grades such as A- or B+. You can also enter percentages such as 91 or 91%.
Formula Used
The calculator uses credit-weighted quality points. First, it converts each grade into base grade points. It multiplies those points by course credits. Then it applies the selected course-level boost and any personal adjustment.
Unweighted GPA = Σ(Base Grade Points × Credits) ÷ Σ(Credits)
Weighted GPA = Σ((Base Grade Points + Level Boost + Adjustment) × Credits) ÷ Σ(Credits)
If you enter a point cap, the calculator limits each course’s weighted points before it multiplies by credits. Percentage grades use common plus-minus boundaries. Your school may use different boundaries or rules.
How to Use This Calculator

Understanding Weighted GPA
A weighted GPA adds extra grade points for demanding classes. These classes may include honors, advanced placement, international programs, or college courses. An A carries the same base value everywhere. Your weighted GPA recognizes course difficulty. Schools use different systems. Many begin with a four-point scale. An A usually earns four points. Honors classes may add one-half point. Advanced classes may add one full point. Your school can use different boosts. Always check its published policy before making important decisions.
Why Credits Matter
Course credits affect the final average. A two-credit course counts twice as much as a one-credit course. This calculator multiplies each course’s points by its credits. It divides quality points by credits. Credits give proper importance to longer courses. A large credit value can change your GPA quickly. Enter credits carefully. Semester classes may have smaller values. Full-year classes may have larger values. Do not assume every transcript uses identical credits. Match the numbers shown by your school whenever possible.
Converting Grades Accurately
You can enter letter grades or percentages. Percentage entries are converted through common grade boundaries. A score of ninety-three or higher becomes an A. A score from ninety through ninety-two becomes an A minus. Local grading rules may differ. The calculator first finds the unweighted grade value. It applies the selected course-level boost. It adds any individual adjustment you enter. The optional point cap limits each weighted course value. This can mirror schools that stop weighted values at five points.
Using Course Levels
Choose Honors for classes receiving the honors boost. Choose Advanced for rigorous programs like AP or IB. Choose Dual Enrollment for college-level coursework. Select Custom when a school assigns a different level bonus. A personal adjustment is useful for unusual policies. Some schools add extra points for specialized pathways. Others use a smaller bonus for selected courses. Keep adjustments at zero unless you know the rule. Large adjustments can produce misleading comparisons. The best result follows your official transcript policy.
Making Practical Comparisons
Compare unweighted and weighted results together. The weighted figure shows both performance and course rigor. Neither number tells the whole academic story. Admissions teams may also review grades, course selection, trends, school context, and achievements. A higher weighted GPA does not ensure better results. Strong grades remain important. Taking too many difficult classes can hurt performance. Build a balanced schedule. Consider your interests, available support, and time commitments. Use this calculation as a planning tool, not as an official transcript replacement.
Reviewing the Result
After calculation, review every course in the breakdown. Look for incorrect credits, grades, or levels. Fix any missing course before relying on the average. Save your inputs for future planning. This tool gives an estimate based on your chosen rules. Counselors and registrars provide the official value. Use their method for applications, rank questions, scholarships, and graduation requirements. A clear record of courses and credits makes future GPA planning easier. Regular updates also help you spot improvement opportunities early.
Frequently Asked Questions
1. What is an unweighted GPA?
An unweighted GPA uses base grade points only. It does not add points for course difficulty. On a common four-point scale, an A is worth four points, even in an advanced class.
2. What is a weighted GPA?
A weighted GPA adds extra points for eligible rigorous courses. Honors, advanced, dual enrollment, and specialized programs may receive different boosts. Policies vary by school and district.
3. Can I enter percentages?
Yes. Enter a number from 0 to 100, with or without a percent symbol. The calculator converts it through common plus-minus grade boundaries before calculating points.
4. Why do credits change my GPA?
Credits determine how much each class affects the final average. A course with more credits contributes more quality points. This reflects the greater time or curriculum value assigned to that course.
5. What point boost should I use?
Use the boosts listed in your school handbook or transcript policy. Many schools use 0.50 for honors and 1.00 for advanced courses, but those values are not universal.
6. Should I use a weighted point cap?
Use a cap only when your school limits weighted course values. For example, a five-point cap prevents a course from exceeding 5.00 after boosts and adjustments.
7. Does this replace my official GPA?
No. This calculator provides an estimate. Schools can use unique grade boundaries, repeated-course rules, exclusions, and rounding methods. Ask your counselor or registrar for the official GPA.
8. Can a weighted GPA exceed 4.00?
Yes. A weighted system can exceed 4.00 when eligible courses receive extra points. The maximum depends on your scale, boosts, course choices, and any point cap.
9. What does personal adjustment mean?
Personal adjustment lets you apply a documented exception for one course. Leave it at zero for normal calculations. Do not use it to inflate grades without an official policy.
10. How are repeated courses handled?
Rules differ. Some schools replace the earlier grade. Others include both attempts. Enter courses according to your school’s transcript rules, then confirm the official approach with staff.
11. Can I save my result?
Yes. Use the CSV button to download a course breakdown. You can also print the result or choose a PDF destination in your browser’s print dialog.
