Weighted high-school GPA calculator
Compare weighted and unweighted high-school GPA from the same courses. Set confirmed Honors, AP and IB bonuses, eligibility threshold and per-course cap.
How it works
A worked example
Two one-credit courses at 4.0 base points give a 4.0 unweighted GPA. If one regular course has no bonus and one AP course earns a 1.0 bonus under a 5.0 course cap, the weighted GPA is 4.5. These are example settings, not a universal school scale.
Assumptions to check
Enter the school’s unweighted points directly; no letter-grade or percentage conversion is assumed. Bonuses apply at or above the chosen base-point threshold. Regular courses earn no bonus. Excluded rows do not count. The cap is per course, not a cap on the number of bonus courses. Selected years, subject eligibility, admissions recalculations and district-specific bonus-course limits must be handled separately.
Read all calculation notes ↗A few useful answers
Do all AP or IB classes get a full extra point?
No. Enter the bonus your school actually gives. AP and IB bonuses are separate inputs, and Honors has its own input.
Can a failed course earn a bonus?
Only when its base points meet the threshold you set. Check your school’s rule; the example threshold prevents low-point results from automatically receiving a bonus.
Is this an official admissions GPA calculator?
No. Admissions bodies can select different subjects, years, caps and grade mappings. This is a configurable school-course calculation, not an official admissions recalculation.
Planning estimates, not official academic results. Your course and institution set the rules.
Weighted versus unweighted GPA
Both averages use the same counted courses and credits. The unweighted result uses base points. The weighted result adds eligible bonuses under your cap. That makes the difference visible without assuming a weighted GPA is interchangeable with another school’s number.
Enter credits and grade points consistently
A full-year course may carry more credit than a semester course. Use the credit units assigned by your school consistently. The base maximum is a validation limit; changing it does not convert existing grades or reassign letter-grade values.
Check eligibility before applying a bonus
Some schools limit bonuses to certain courses or grades. Mark ineligible courses Regular or Exclude only as appropriate to the school’s GPA rules. This version cannot automatically choose which courses qualify under an admissions authority’s separate capped formula.
