Calculate weighted and unweighted high school GPA

This tool uses a common 4.0 base scale, a 0.5 honors boost and a 1.0 AP/IB boost. Schools and colleges may recalculate GPA using different rules.

Formula and interpretation

How this calculation works

The calculator keeps the weighting visible so you can trace the result and compare it with the method in your syllabus, transcript or institutional policy.

GPA = total credit-weighted grade points ÷ total GPA credits

Worked calculation

Example: the course level changes only the weighted estimate

An A in AP Biology earns 4.0 unweighted points and 5.0 weighted points in this model. A B+ in Honors English earns 3.3 unweighted and 3.8 weighted points. Standard-course grades receive no added weight.

Before relying on the estimate

Check the rules behind your numbers

  • Confirm whether your school weights honors, AP, IB or dual-enrollment courses.
  • Check whether plus and minus grades receive distinct values.
  • Use the correct credit value for semester and year-long courses.
  • Remember that colleges may recalculate the transcript using their own core-course rules.
  • Do not treat the weighted estimate as the official class-rank GPA.

Questions students ask

Free High School GPA Calculator FAQs

What is an unweighted GPA?

It uses the base grade-point value without adding difficulty points for honors, AP or IB coursework.

What is a weighted GPA?

It adds points for designated advanced courses. The size of the boost and any maximum scale are local policy choices.

Do colleges use the GPA printed by my high school?

Some do, while others recalculate selected academic courses. Always check the admissions method for the institution involved.

Can this calculate a 5.0 scale?

The weighted scenario can reach 5.0 for an A in an AP/IB course, but it does not reproduce every school-specific 5.0 policy.
