AP GPA Calculator
Weighted and unweighted GPA,
side by side.
Add every AP, Honors, and Regular course with its grade and credit hours. See your weighted GPA on the 5.0 scale and your unweighted GPA on the 4.0 scale — the two numbers colleges actually compare.
Getting started
How to use this
calculator
Add each course with its course type
Enter a course name (optional), select the letter grade you received, choose the course type — AP/IB, Honors, or Regular — and enter credit hours. Most high school courses are 1 credit per year-long course (0.5 for semester courses). Add a row for every graded course on your transcript.
Select the correct course type for each row
AP and IB courses get the +1.0 boost (A = 5.0). Honors courses get +0.5 (A = 4.5). Regular courses stay at 4.0 max. If your school doesn't weight Honors courses, select "Regular" for them — only AP/IB will boost the weighted GPA.
Click "Calculate GPA"
Both GPAs appear side by side instantly — your unweighted GPA on the 4.0 scale and your weighted GPA on the 5.0 scale. The gap between the two numbers shows exactly how much your course rigor is worth in GPA points.
Experiment with "what if" AP swaps
Change a Regular course to AP and recalculate. See how much the weighted GPA moves — and how much the unweighted stays the same. This reveals the real-world benefit (and risk) of loading your schedule with AP courses before you register.
The formula
How weighted and
unweighted GPA differ
Both GPA types use the same weighted-average formula — the difference is which grade-point table you apply. Unweighted GPA treats every course as equal, capping A at 4.0 regardless of difficulty. Weighted GPA rewards harder courses with bonus points.
For example, a student taking AP Calculus (A, 1 credit) and Regular Spanish (B, 1 credit) gets an unweighted GPA of (4.0 + 3.0) / 2 = 3.50 and a weighted GPA of (5.0 + 3.0) / 2 = 4.00. The Calculus A earns more weighted points because the course is more demanding.
College admissions offices typically look at both. The weighted GPA captures rigor; the unweighted GPA allows direct comparison across schools with different AP offerings. It's worth knowing both before you apply.
Grade point scales
Weighted point
values by course type
These are the CollegeBoard-aligned grade-point values used by the majority of US public high schools. Some schools cap Honors at 4.5 or use a different AP-scale ceiling — always check your school's grading policy.

The breakeven point: when AP pays off
An AP course adds +1.0 to the grade point value — but only if you earn a competitive grade. The question isn't whether to take AP courses; it's whether the grade you'll earn in an AP course produces a higher weighted GPA than the grade you'd earn if you stayed in Regular.
Here's the breakeven table for a single 1-credit course:
| Regular grade | Regular pts | AP grade needed to match | AP pts |
|---|---|---|---|
| A | 4.0 | B+ or higher (4.3 AP) | 4.3 |
| A− | 3.7 | B or higher (4.0 AP) | 4.0 |
| B+ | 3.3 | B− or higher (3.7 AP) | 3.7 |
| B | 3.0 | C+ or higher (3.3 AP) | 3.3 |
If you'd earn an A in Regular but only a B− in AP, the AP course hurts your weighted GPA (3.7 vs 4.0). The AP boost only pays off when you earn at least one full letter grade above the breakeven point for your comparison Regular grade.
How colleges use weighted vs unweighted GPA
Most four-year colleges recalculate your GPA on their own scale when reviewing applications. The specific approach varies:
- UC system — recalculates on a 4.0 scale with its own weighting formula (A in AP = 5.0, capped at one bonus point per course, maximum 8 weighted courses counted).
- Common App colleges — receive both your school-reported GPA and your transcript; many build their own GPA from scratch using course-by-course grades.
- Some selective colleges — strip all weighting and compare on a pure unweighted 4.0 scale, then separately evaluate course rigor from the transcript.
The practical implication: the number this calculator shows is your school's weighted GPA. College admissions may produce a different number from the same transcript. What matters most is the underlying grade in each course — a B+ in AP Calculus is a better signal than an A in Regular Math, regardless of what any GPA formula outputs.
Class rank and AP loading
At schools that publish class rank using weighted GPA, taking more AP courses is a direct competitive strategy — every AP course gives you a chance to earn points other students in Regular courses can't. However, loading up on APs and earning Bs can actually lower your weighted GPA relative to classmates who took fewer APs and earned As. The optimal strategy is enough AP courses to show rigor — typically 4–8 by graduation — in subjects where you can genuinely compete for an A or B+.
Course-load decisions, by the numbers
AP loading strategy:
how your schedule affects both GPAs
Same student, same performance level (mostly B/B+ grades), three different course-type mixes. All scenarios use 6 courses × 1 credit each. The only variable is how many are AP, Honors, or Regular.
2 APs + 2 Honors + 2 Regular
Student earns B+ in all 6 courses. AP courses (B+ = 4.3), Honors (B+ = 3.8), Regular (B+ = 3.3). This is a realistic schedule for a committed student.
= (8.6 + 7.6 + 6.6) ÷ 6 = 22.8÷6 = 3.80 weighted
Unweighted: all B+ (3.3) in 6 courses
= 3.30 unweighted
Gap: +0.50 — rigor adds half a point
This student shows colleges a 3.8 weighted GPA with clear rigor signal. The 0.50 gap between weighted and unweighted is meaningful and completely visible to admissions readers who see both numbers.
6 APs — grade pressure drives Bs lower
Student loads all 6 courses as AP — a very demanding schedule. Under that pressure, grades slip from B+ to B in 4 courses, with B− in 2 harder ones.
= (16.0 + 7.4) ÷ 6 = 23.4÷6 = 3.90 weighted
Unweighted: (4×3.0 + 2×2.7) ÷ 6
= (12.0 + 5.4) ÷ 6 = 17.4÷6 = 2.90 unweighted
Gap: weighted looks strong — unweighted tells the real story
A 2.90 unweighted GPA is a serious red flag at selective colleges, even with a 3.90 weighted. Admissions readers look at both. Earning B− in AP courses costs more than it gains versus an A in Regular — this is the AP overload backfire scenario.
The single-course AP decision
A student debating: take AP Biology or Regular Biology? In Regular, they're confident of an A. In AP, they expect a B−.
AP Bio (B− = 2.7 unweighted, 3.7 weighted)
Weighted comparison:
Regular A = 4.0 > AP B− = 3.7
Unweighted comparison:
Regular A = 4.0 >> AP B− = 2.7
AP B− is worse on BOTH scales
The AP course only helps if the grade earned in AP beats the breakeven (for a Regular A comparison: need AP B+ or better = 4.3 weighted). A B− in AP is the worst outcome — it penalizes both GPAs and signals struggle in a hard course. Take the AP course only when you can realistically earn a B+ or better.

Common questions
AP GPA Calculator FAQ
What is a weighted GPA?
A weighted GPA adds bonus points for harder courses. AP and IB earn +1.0 (A = 5.0), Honors earn +0.5 (A = 4.5), and Regular courses stay at A = 4.0. It rewards rigor alongside grades.
How is AP GPA calculated?
Multiply each course's grade points by its credit hours, sum those products, and divide by total credit hours. Formula: GPA = Σ(points × credits) / Σ(credits). The calculator does this for both weighted and unweighted simultaneously.
Does a weighted GPA matter for college admissions?
Yes and no. Most colleges recalculate GPA on their own scale. What matters most is course rigor — the mix of AP and Honors courses — alongside the actual grades earned.
What's the highest possible weighted GPA?
On a 5.0 weighted scale, the maximum is 5.0 — earned by earning an A in every AP or IB course. Most students taking a realistic mix land between 3.5 and 4.5.
How many AP credits should I enter?
For GPA purposes, each year-long course typically counts as 1 credit. Semester courses count as 0.5. If your school uses different values (Carnegie units), use those instead.
What if my school doesn't weight Honors?
Select 'Regular' for those courses. Not all schools apply Honors weighting — some only boost AP/IB. The unweighted GPA will still be accurate regardless.
Does class rank use weighted or unweighted GPA?
It depends on the school. Most schools that publish rank use weighted GPA because it rewards rigor. Check your school's student handbook or guidance office.
Will colleges see my weighted or unweighted GPA?
Both. The Common App asks for your GPA and the scale your school uses. Colleges also get your official transcript and often recalculate on their own scale.
How is this different from the College GPA Calculator?
This AP GPA Calculator is for high school with weighted AP/Honors points. The College GPA Calculator uses a flat 4.0 scale for all university courses — no difficulty weighting.
My school uses a 10-point grading scale. What do I enter?
On a 10-point scale, the letter grades are the same — A is still A, B is still B. Just enter the letter grade your school assigns. The point values in this calculator handle the rest.
What's an IB course worth on this scale?
IB (International Baccalaureate) courses receive the same weighting as AP courses — an A earns 5.0 weighted points. Select 'AP / IB' in the course type column for any IB subject.

Grading standards
and references
The 5.0 weighted scale and grade-point values used in this calculator align with the College Board's AP program grading guidance and are consistent with practices reported to NCES IPEDS by US high schools. Unweighted 4.0 values match those used in College Scorecard GPA reporting.
Class rank and GPA weighting policies vary by district. The College Board publishes AP course requirements and grade standards. Individual school district policies are maintained by state education departments — for example, California Department of Education and Texas Education Agency.
