GPA Calculator

Calculate semester, cumulative, and target GPA with credit weighting, honors bonuses, and AP course weighting.

Calculation mode

Average the courses in one term.

Course inputs

Build your course average.

Add each course, choose its letter grade and credits, then compare unweighted and weighted GPA results.

The estimate uses a 4.0 unweighted scale. Honors adds 0.5 and AP adds 1.0 to weighted points, capped at 5.0 per course. School policies vary.

About this calculator

Method, formulas, and limits.

What this does

Calculates semester unweighted and weighted GPA from course grades and credits, combines a previous record into a cumulative GPA, and reverses a target GPA into the average needed across future credits.

Who it is for

High-school and college students, parents, counselors, and applicants checking a semester GPA or planning how course choices affect an academic average.

How it works

Each letter grade becomes grade points, then quality points are multiplied by course credits. Semester mode averages the listed courses. In cumulative mode, add one row for each previous term. Expand a term and enter its courses to calculate that term's exact GPA and quality points directly; summary-only rows can use official quality points or estimate them as GPA × credits. The calculator adds previous and current quality-point totals before dividing by total credits. Target mode solves the average GPA required across future credits. The unweighted result uses a 4.0 scale; the weighted result adds 0.5 for honors and 1.0 for AP courses, capped at 5.0 points per course.

Limitations

Schools use different grade scales, plus/minus rules, repeated-course policies, and weighting systems. Cumulative and target modes use the unweighted 4.0 scale. Confirm the official policy with your school.

Key calculations

Quality points
quality points = grade points × course credits
Unweighted GPA
unweighted GPA = total unweighted quality points / total credits
Weighted GPA
weighted GPA = total weighted quality points / total credits; honors adds 0.5 and AP adds 1.0, capped at 5.0
Cumulative GPA
cumulative GPA = (previous quality points + current quality points) / total credits
Target GPA
required future GPA = (target GPA × total future credits − current GPA × completed credits) / additional credits

Reference ranges

Unweighted 4.0 scale
The standard result maps A-level work near 4.0 and F-level work to 0.0 before credit weighting.
Honors weighting
The estimate adds 0.5 grade points to honors courses, a common but not universal convention.
AP weighting
The estimate adds 1.0 grade point to AP courses and caps individual weighted points at 5.0.
Cumulative GPA
Combines historical terms and the current term by adding exact quality-point totals and dividing by total credits.
Target GPA
Solves the average unweighted GPA required across future credits; a result above 4.0 is not reachable on this scale.

How to use it

  1. 1.Choose a modeUse Semester for one term, Cumulative to combine a previous record, or Target to plan a future GPA milestone.
  2. 2.Add each courseEnter a course name, its letter grade, and the number of credits or units. In cumulative mode, expand a history row to enter that term's courses.
  3. 3.Choose course rigorUse Standard, Honors, or AP to show the optional weighted GPA effect.
  4. 4.Review the resultCompare the GPA result with the cumulative or target scenario, then confirm your school's policy.

Unweighted GPA uses the regular grade-point scale. Weighted GPA adds a rigor bonus for advanced courses such as honors or AP, depending on the selected convention.

Yes. A course with more credits contributes more quality points than a course with fewer credits.

This estimate adds 1.0 point to an AP course and caps the result at 5.0. Schools can use different policies, so verify your transcript rules.

No. It is a planning estimate. Your school or institution's registrar determines the official GPA.

Add each previous term with its GPA and credits, or expand a term to enter its individual courses. Course details calculate exact quality points from grades and credits. For summary-only rows, official quality points avoid rounding error; otherwise the calculator estimates GPA × credits before combining the historical and current totals.

Enter your current GPA, completed credits, target GPA, and future credits. The calculator solves the average GPA required in those future credits; a value above 4.0 means the target is not reachable on the standard scale.
