How to calculate your college GPA
Multiply each course's grade points by its credit hours, add those up, then divide by your total credit hours.
| Course | Grade | Points | Credits | Points x credits |
|---|---|---|---|---|
| English Composition | A | 4.0 | 3 | 12.0 |
| Biology with lab | B+ | 3.3 | 4 | 13.2 |
| Calculus I | A- | 3.7 | 3 | 11.1 |
| Total | 10 | 36.3 |
36.3 ÷ 10 = a semester GPA of 3.63.
To get your cumulative GPA, add your earlier record. Say you already had a 3.40 GPA over 30 credits: that is 102.0 points. (102.0 + 36.3) ÷ (30 + 10) = 138.3 ÷ 40 = 3.46.
In the calculator, open “Add earlier semesters” and enter your current cumulative GPA and the credits already completed. The calculator adds the new courses on top of that prior record. Colleges usually report the unweighted cumulative, while the weighted figure can still help when your school uses weighted courses.
Enter the same courses above and the calculator shows both numbers.
Weighted vs unweighted GPA
An unweighted GPA puts every course on the same 0–4.0 scale. The letter grade sets the points, and the difficulty of the course does not change them. This makes the unweighted result a straightforward view of grades across the course list.
A weighted GPA adds a bonus for harder courses. Common values are +0.5 for Honors and +1.0 for AP, IB or dual-enrollment courses. With that standard weighting, an A in an AP course counts as 5.0. That is why a weighted GPA can go above 4.0, and why people sometimes describe it as a “5.0 scale.” The table below shows exactly what this calculator uses.
Schools set their own rules, though. Some choose different bonus values, some do not weight grades at all, and some count an A+ as 4.33. This calculator starts with the common 4.0 values and standard bonuses, and the A+ checkbox lets you use 4.33 where that applies. Your school transcript remains the official number, so use its published scale when comparing results.
Credit hours decide how strongly a course affects the answer. A 4-credit course counts four times as much as a 1-credit course. If you leave the credits field blank, every course counts the same. This works well for a simple course average, while entering credits lets you reflect a semester where classes carry different amounts of credit.
Converting between unweighted and weighted scales is not a simple ratio. The bonus depends on which individual courses were Honors, AP, IB or dual enrollment. Two students with the same unweighted GPA can therefore have different weighted GPAs. That is why this calculator works from your course list instead of multiplying one GPA by a conversion factor.
| Letter | Unweighted points | Honors | AP/IB |
|---|---|---|---|
| A+ | 4.0 | 4.5 | 5.0 |
| A | 4.0 | 4.5 | 5.0 |
| A- | 3.7 | 4.2 | 4.7 |
| B+ | 3.3 | 3.8 | 4.3 |
| B | 3.0 | 3.5 | 4.0 |
| B- | 2.7 | 3.2 | 3.7 |
| C+ | 2.3 | 2.8 | 3.3 |
| C | 2.0 | 2.5 | 3.0 |
| C- | 1.7 | 2.2 | 2.7 |
| D+ | 1.3 | 1.8 | 2.3 |
| D | 1.0 | 1.5 | 2.0 |
| D- | 0.7 | 1.2 | 1.7 |
| F | 0.0 | 0.0 | 0.0 |
A+ is 4.0 by default and 4.33 at some colleges; use the calculator checkbox to switch.
| Level | Bonus |
|---|---|
| Regular | +0.0 |
| Honors | +0.5 |
| AP / IB / Dual enrollment | +1.0 |
