GPA Calculator
Calculate a credit-weighted GPA from your courses. Add grades and credits, optionally weight honors/AP, and fold in a previous GPA or target.
Calculate
Term GPA
The formula
Multiply each course’s grade points by its credit hours, sum those products, then divide by total credits. That is the standard credit-weighted GPA.
Worked example
- Courses: A (4.0)×3 credits, B (3.0)×3 credits, A (4.0)×4 credits.
- Quality points = 12 + 9 + 16 = 37.
- Total credits = 10 · Term GPA = 37 ÷ 10 = 3.70 (letter A− on a plus/minus scale).
Result: Term GPA 3.70 / 4.0 · 10 credits · A−
How GPA is calculated
GPA is a weighted mean of grade points, where weights are credit (or unit) hours. A 4-credit A moves the average more than a 1-credit A.
Credit weighting
Each row contributes points × credits to the numerator and credits to the denominator. Courses with zero credits are ignored. At least one positive-credit course is required.
Scales and letters
Choose the scale that matches your transcript: plain 4.0, 4.0 with plus/minus, a 5.0 honors scale, 10-point, or percentage. Letter conversion follows typical U.S. mappings (A = 4.0, A− = 3.7, and so on) — your school’s catalog may differ slightly.
Weighted GPA (honors / AP)
When Weighted GPA is on, letter grades on 4.0 / plus-minus scales get +1.0 point (capped at 5.0), which matches a common U.S. honors/AP convention. Turn it off for an unweighted average, or pick the 5.0 scale if that is how your school stores points.
Previous GPA and goals
Optional prior GPA and credits combine with this term for an overall average. A target overall GPA shows the term average you would need with the credits you entered. Registrar rules for repeats, forgiveness, and pass/fail are not modeled.
Interesting facts
4.0 scale
The U.S. 4.0 GPA scale is widely used, but many countries report percentages, 10-point scales, or classification bands instead.
Weighted vs unweighted
Weighted GPAs give extra points for honors or AP courses. Unweighted GPAs treat every A the same — compare apples to apples when schools ask for one or the other.
Credit hours matter
GPA is credit-weighted: a 4-credit A moves the average more than a 1-credit A with the same letter.
Transcript policies differ
Some schools drop failed repeats; others average all attempts. Always check the registrar’s rules before treating a web estimate as official.
Holistic admissions
Selective universities weigh GPA alongside rigor, essays, and recommendations — GPA is necessary but rarely sufficient alone.
Frequently asked questions
For each course, multiply grade points by credit hours. Add those products, then divide by total credit hours. This calculator does that for every course you add.
On 4.0 and plus/minus scales it adds +1.0 to each letter grade (capped at 5.0). Use it when your school boosts honors/AP the same way, or enter already-weighted points instead.
Yes. Open Previous GPA and goal, enter your current cumulative GPA and credits so far. The dashboard shows an overall GPA that blends prior work with this term.
Match the scale your grades are stored in: 4.0, 4.0 with plus/minus, 5.0 honors, 10-point, or percentage. Mixing scales in one average is not meaningful.
It matches the arithmetic of credit-weighted GPA. Official GPAs can differ because of school-specific rounding, exclusions, or repeat rules.
