Free Weighted GPA calculator with clear step-by-step results.
A weighted GPA credits the extra difficulty of honors, AP or IB courses by adding a bonus to their grade points before dividing by credits. The mechanics are: quality points are grade point × credits, a bonus of typically 0.5 or 1.0 is added per weighted credit, and the total is divided by all credits attempted. This is why a weighted GPA can exceed the nominal 4.0 maximum, and why it can only be compared between students on the same weighting policy.
Weighted quality points
Weighted points = unweighted quality points + honors credits × bonus per credit
GPA
Weighted GPA = weighted points ÷ total credits attempted
Weighting policies, scales and which courses qualify are set by each school or district. Use your official transcript and your institution's published policy for any decision that depends on the figure.
Most commonly 0.5 for honors and 1.0 for AP or IB, but some use 0.33, some weight only the letter grade rather than per credit, and some do not weight at all. Use your school's published policy — the number here is a default, not a standard.
Because the bonus is added on top of a 4.0-scale grade point. A student taking mostly AP courses with 1.0 bonuses can legitimately exceed 4.0, which is normal under a weighted scheme.
Many recalculate from your transcript using their own weighting, so neither figure is universal. Reporting both, as here, is the safest basis for comparison.
