Weighted GPA Calculator

A weighted GPA gives extra grade points for harder courses. The most common US convention adds 1.0 to the grade point for AP and IB classes and 0.5 for Honors classes, capping a regular A at 4.0, an Honors A at 4.5, and an AP or IB A at 5.0. Many schools use variations — some weight dual-enrollment college courses the same as AP, some use different bonuses, and some only weight certain subjects. Always check your school's policy before relying on a specific number for college applications or honors lists.

This GPA calculator with weighted grades lets you mark each course as Regular, Honors, or AP/IB and applies the common bonus on top of your grade. Like the unweighted calculator, it runs in your browser and keeps drafts only on your device.

1. Add a row for each course with the credit hours.
2. Pick the course type: Regular, Honors, or AP/IB.
3. Enter the grade you earned.
4. The calculator adds the weighting bonus and averages the result by credits.

Three 1-credit courses: AP A (5.0), Honors A (4.5), Regular B (3.0). Weighted GPA = (5.0 + 4.5 + 3.0) ÷ 3 = 4.17. The same three classes calculated unweighted would be (4.0 + 4.0 + 3.0) ÷ 3 = 3.67.

Weighted GPAs are most useful for comparing students inside the same school, because they reward course difficulty. College admissions offices often recalculate GPAs using their own scales, so the weighted number you see here is an estimate of how your school's policy might score your record, not a universal value.

How do I calculate weighted GPA?

Convert each course grade to grade points, add the course-level bonus when applicable, multiply by credits, then divide total weighted quality points by total credits.

What weighting bonus does this calculator use?

It uses the common US convention: +0.5 for Honors and +1.0 for AP/IB on top of the standard 4.0 scale. If your school uses different bonuses, treat the result as an approximation.

Can I convert weighted GPA to unweighted GPA?

Not exactly from the final number alone. Use the course list to calculate both versions side by side, because the unweighted GPA removes course-level bonus points before averaging.

How do I calculate GPA with weighted grades?

Enter each course, credits, letter grade, and course level. The calculator applies the selected weighting bonus and also shows the unweighted GPA for comparison.
