Weighted GPA Calculator

Live unweighted vs weighted twin from the same course list, with Honors/AP bumps and a bump quality-point peel so rigor policy stays visible.

Educational sketch only. Your school or district handbook overrides these bump values. Not admissions counseling; many colleges recalculate GPA on their own scale.

Unweighted vs weighted from the same list

Unweighted GPA averages base 4.0-scale letter points by credits. Weighted GPA adds rigor bumps before that average. This page’s framing is that twin: one course list, two policies, so a transcript “5.0-looking” average never hides the unweighted story.

That is different from the term / cumulative GPA calculator, which merges prior credits without Honors/AP bumps, and different from the final grade calculator, which solves for one exam score inside a course.

Decision framing: “What is my 4.0-scale average, and how much does local weighting lift it?”

Rigor bump policy sketch

This board’s educational sketch uses Regular +0, Honors +0.5, and AP/IB +1.0 on top of the letter’s base points, with an optional 5.0 cap per course. Many districts differ. Always prefer your handbook over this sketch when they conflict.

Load Mixed rigor, then flip one AP course to Regular. Watch only the weighted side and bump peel move. That is the product of weighting policy.

Unweighted vs weighted twin board

The twin keeps both GPAs visible. Colleges and scholarship forms may ask for one or the other; some recalculate entirely. Publishing only the weighted number without the unweighted twin invites confusion.

Load All regular. Lift ≈ 0 and both sides match. Then load AP-heavy to see a clear lift.

Bump quality-point peel

Weight lift = weighted GPA − unweighted GPA. Bump quality points = Σ (weighted points − base points) × credits. That peel isolates how many quality points came from policy bumps rather than letter grades alone.

AP-heavy with mid letters can still show a large lift because +1.0 bumps stack across credits. Honors tilt shows a milder +0.5 story.

Course quality-point rails

Each course rail shows letter → base points → weighted points, then unweighted QP versus weighted QP. Credits matter: a 0.5-credit PE A moves the average less than a 1.0-credit AP B+.

Rename courses freely; labels are for your notes. Letters and weights drive the math.

What the panel actually computes

Common 4.0 letter map. Non-negative credits. Optional cap at 5.0 weighted points per course.

basePts = letterToPoints(letter) bump = 0 | 0.5 | 1.0 // Regular | Honors | AP/IB sketch weightedPts = min(basePts + bump, 5) // if cap on UW GPA = Σ(basePts × credits) / Σ credits W GPA = Σ(weightedPts × credits) / Σ credits lift = W − UW bumpQP = Σ((weightedPts − basePts) × credits)

Where this hands off

After rigor-weight literacy, hand off for term/cumulative merges, single-course finals, or college cost framing.

Worked scenarios

Scenario A: Mixed rigor. AP Bio A−, Honors Eng B+, Algebra A, History B. Twin shows UW on the 4.0 story and W with bumps; bump peel quantifies the policy lift.

Turn the 5.0 cap off, then on, with an A in AP. Cap on keeps weighted points at 5.0.

Scenario B: AP-heavy. Three AP courses plus a half-credit PE. Lift is the teaching beat even when some letters are B range.

Scenario C: All regular. Lift ≈ 0. Weighted and unweighted match. Use this as a control before adding rigor.

Scenario D: Honors tilt. Two +0.5 courses. Milder lift than AP-heavy; good for handbook +0.5 policies.

Common mistakes

Reporting only weighted GPA when a form asks for unweighted (or the reverse).
Using +1.0 bumps when your school uses a different table.
Ignoring credit hours (treating every course as equal weight).
Mixing this with cumulative prior-credit merge without listing prior terms.
Assuming colleges keep your school’s weighted scale unchanged.
Treating this sketch as official transcript math or admissions advice.

How to use this panel

Load a scene preset or set letter, credits, and weight for each course.
Toggle the 5.0 cap to match your handbook if needed.
Read the UW/W twin, lift, bump QP peel, and course rails.
Share when you want URL state. Typing does not rewrite the address bar. Confirm final figures on your official transcript.

Frequently asked questions

What is the difference between unweighted and weighted GPA?

Unweighted GPA uses the base 4.0 letter scale only. Weighted GPA adds rigor bumps (this board’s sketch: Honors +0.5, AP/IB +1.0) before averaging by credits. The twin shows both from the same course list.

How is this different from the term/cumulative GPA calculator?

The other GPA page focuses on this-term average versus a cumulative merge with prior credits. This page focuses on rigor weighting: unweighted versus weighted for the courses you list.

What is the bump quality-point peel?

Bump QP is the extra quality points that come only from weighting (weighted points minus base points, times credits). It shows how much of the lift is policy, not letter grades alone.

Do all schools use +0.5 / +1.0?

No. Weighting schemes vary widely (some use 5.0 scales differently, some weight only semesters, some exclude electives). Match your handbook. This board is a common educational sketch.

What does the 5.0 cap do?

When enabled, weighted points per course cannot exceed 5.0 (for example an A in AP stays 5.0, not 5.0+). Turn the cap off only if your school allows higher.

Is weighted GPA what colleges recalculate?

Many colleges recalculate GPA on their own scale and may ignore local weighting. Treat school-weighted GPA as one transcript signal, not a guaranteed admissions metric.

Are letter conversions fixed?

This board uses a common 4.0 letter map (A=4.0, A−=3.7, …). If your school publishes different cutoffs, enter the nearest letter that matches your transcript policy.
