WHO IT HELPS & HOW TO USE IT

How to use the high school GPA calculator

List semester courses with letter grades and levels, then compare unweighted and weighted GPA.

  1. Add each course with letter grade, level (Regular / Honors / AP·IB), and credits if needed.
  2. Toggle whether the primary result features weighted or unweighted GPA.
  3. Compare both GPAs in the result card before trusting a transcript estimate.

Before you rely on the result: Weight bumps are a common US pattern, not universal. Caps at 5.0. Not for college credit-hour GPA.

UNDERSTAND YOUR RESULT

How high school weighted GPA works

Unweighted = Σ (letter points × credits) ÷ credits
Weighted = Σ (min(letter points + bump, 5.0) × credits) ÷ credits

Bumps: Honors +0.5, AP/IB +1.0. Regular courses use the letter map only.

FREQUENTLY ASKED QUESTIONS

High School GPA Calculator FAQ

What is the difference between unweighted and weighted high school GPA?

Unweighted uses the standard 4.0 letter map for every course. Weighted adds +0.5 for Honors and +1.0 for AP/IB on that map (capped at 5.0 in this tool). Your district may use different bumps.

How should I enter semester courses?

Add one row per semester course (or per year if your school averages yearly). Use the credits/semesters field if some courses count more than others; otherwise leave credits at 1.

Does this match my school’s weighted scale?

Many US high schools use Honors +0.5 and AP/IB +1.0 on a 4.0 base, but policies vary. Always check your counseling office’s scale for transcripts and college apps.

Can I see both GPAs at once?

Yes. The result card always shows unweighted and weighted GPA; the toggle only chooses which number is featured as primary.

Is this the same as a college GPA calculator?

No. College GPA usually weights by credit hours without Honors/AP bumps. Use the college GPA calculator for university coursework.

Why might colleges recalculate my GPA?

Many colleges recompute GPA with their own course lists and weighting rules. Treat this as a planning estimate.
