Your unweighted GPA is the most universally understood version of your grade point average. Unlike weighted GPA, it doesn't adjust for course difficulty — every class is graded on the same 4.0 scale regardless of whether it's standard, honors, AP, or IB. Colleges use it as a consistent benchmark across students from different schools with different course offerings.
Calculating it is straightforward once you understand the formula. This guide walks through the exact steps, the grade point scale, worked examples, and the key differences between unweighted and weighted GPA.
Unweighted GPA = Total Quality Points ÷ Total Credit Hours
Quality points are calculated by multiplying the grade point value of each course by the number of credit hours it carries. You add up the quality points from all courses, then divide by the total credit hours attempted. For a full worked example across multiple semesters, see How to Calculate Cumulative GPA.
Formula: GPA = Σ (Grade Points × Credit Hours) ÷ Σ Credit Hours
Every letter grade maps to a specific number on the 4.0 scale. This is the conversion most US high schools and colleges use for unweighted GPA:
| Letter Grade | Grade Points | Percentage Range |
|---|---|---|
| A+ / A | 4.0 | 93–100% |
| A- | 3.7 | 90–92% |
| B+ | 3.3 | 87–89% |
| B | 3.0 | 83–86% |
| B- | 2.7 | 80–82% |
| C+ | 2.3 | 77–79% |
| C | 2.0 | 73–76% |
| C- | 1.7 | 70–72% |
| D+ | 1.3 | 67–69% |
| D | 1.0 | 63–66% |
| D- | 0.7 | 60–62% |
| F | 0.0 | Below 60% |
Note: Some schools award A+ a value of 4.3 rather than 4.0. If your school uses this policy, your maximum unweighted GPA can technically exceed 4.0. Most schools cap A+ at 4.0 for unweighted calculations — check your school's handbook to confirm.

Use the GPA Calculator →Unweighted GPA treats every course the same. An A in AP Calculus and an A in a standard elective both contribute 4.0 grade points per credit. Weighted GPA adds extra grade points for more challenging courses — typically +0.5 for Honors and +1.0 for AP or IB — before calculating the average. This allows weighted GPAs to exceed 4.0.
| Feature | Unweighted GPA | Weighted GPA |
|---|---|---|
| Scale | 0.0 – 4.0 | 0.0 – 5.0 (typically) |
| Course difficulty | Not reflected | Reflected via bonus points |
| Max value | 4.0 (or 4.3 at some schools) | 5.0 for AP/IB A grades |
| Used by colleges for comparison | Yes — standardized | Varies — recalculated by some schools |
Many colleges recalculate your GPA using their own formula when reviewing your application, stripping out weighting bonuses and sometimes excluding certain course types. This is why your unweighted GPA often ends up being the number that matters most in a standardized admissions comparison — even if you have a strong weighted GPA.
A student who takes 4 AP courses and earns B's in them can post a similar weighted GPA to a student who takes 0 AP courses and earns straight A's — but their unweighted GPAs tell a very different story (roughly 3.0 vs. 4.0). This is exactly why colleges look at both numbers side by side rather than relying on weighted GPA alone: weighted GPA shows rigor, unweighted GPA shows consistency of performance regardless of course difficulty.
If you want to see both numbers calculated together from your actual courses, the Weighted GPA Calculator shows unweighted and weighted GPA side by side from the same course list.
Most application platforms (including the Common App) ask for both, so you rarely have to choose. But when a scholarship or program only asks for one number without specifying, use unweighted unless the form explicitly says "weighted" — it's the more universally understood figure and avoids any confusion about which weighting scale you used. If you're unsure, listing both with a brief note ("3.4 unweighted / 4.1 weighted") is always a safe option in an essay or resume context.
Even without weighting bonuses, not all grades affect your unweighted GPA equally — a grade in a 4-credit course contributes four times the quality points of a grade in a 1-credit course. See How to Calculate GPA with Different Credit Hours for the full breakdown with worked examples.
Assuming unweighted and weighted use the same scale. A 4.0 unweighted GPA is a perfect straight-A record. A 4.0 weighted GPA on a 5.0 scale is well below perfect. Don't compare these two numbers directly without confirming which scale is being used.
Manually re-adding weighting bonuses when a form asks for "GPA" without specifying. If a form doesn't specify weighted or unweighted, report the number exactly as it appears on your official transcript rather than recalculating — schools want your reported number to match their records.
For general calculation mistakes that apply to both weighted and unweighted GPA (pass/fail handling, withdrawals, percentage conversion), see the mistakes section in How to Calculate Cumulative GPA.
Colleges use unweighted GPA as a baseline for comparison because it removes the variation in how schools weight advanced courses. Some high schools weight aggressively; others don't weight at all. Unweighted GPA gives admissions officers a common denominator across applicants from thousands of different schools.
That said, context still matters. A 3.5 unweighted GPA from a rigorous high school with 6 AP courses reads differently than a 3.5 from a school with limited advanced options. Many colleges recalculate your GPA themselves using a standardized method — often the UC system's formula or their own internal scale — so the GPA your counselor reports and the GPA the college uses may differ slightly.

| Unweighted GPA | Letter Grade Equivalent | General Standing |
|---|---|---|
| 3.7 – 4.0 | A / A- | Excellent — competitive for selective schools |
| 3.3 – 3.69 | B+ / A- | Strong — solid range for most 4-year universities |
| 3.0 – 3.29 | B / B+ | Good — meets requirements at most schools |
| 2.7 – 2.99 | B- / B | Average — may limit options at selective schools |
| 2.0 – 2.69 | C+ / C | Below average — minimum threshold at many colleges |
| Below 2.0 | C / D | Academic probation risk at most institutions |
