Each term's GPA, and your cumulative GPA after it.
How much higher or lower your GPA is because of each course, compared with leaving it out. Big courses with grades far from your average move it most.
How it's calculated: each grade becomes grade points (A = 4.0, A− = 3.7, B+ = 3.3 and so on), each course's points are multiplied by its credits, and the total is divided by the credits. Pass/fail and withdrawn courses don't count toward GPA. With an international scale, every course is converted to a US grade first and then averaged by credits, which is how credential evaluators such as WES work out a US GPA.
GPA calculator for college and high school: credit-weighted GPA, weighted GPA with honors and AP courses, cumulative GPA across terms, and GPA from international grades such as German, UK, Indian and Chinese marks.
Every bar runs from the worst grade on the left to the best on the right. The shaded stretch is the equivalent grade band, and the hatched part is below the pass mark.

Two methods, shown side by side. The conversion tables match grades by meaning, the way credential evaluators such as WES do, and the way Ontario's OUAC table does for Canadian percentages. The proportional formula is the modified Bavarian formula German universities use: it places your grade at the same point between the pass mark and the best grade on the new scale. The two can differ by several tenths, especially for systems where top marks are rare. The institution you apply to has the final say.

Where your cumulative GPA goes as you add credits at different averages. The more credits you already have, the flatter the lines.
| Grades | Courses that need an A | Final GPA |

The formula: average needed = (target × (credits so far + credits to come) − current GPA × credits so far) ÷ credits to come. Because it divides by the credits still to come, a GPA gets harder to move the further you are into your degree. One strong term moves a first-year GPA a lot and a senior's GPA only a little.
Target GPA calculator: the grade average you need to raise your GPA to a goal, the highest GPA you can still reach, how many credits of straight A's it takes, and combinations of A's and B's that get you there.
Each grade is turned into grade points on a 4.0 scale (A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0 and so on), multiplied by the course's credits, added up, and divided by the total credits. A 4-credit course therefore counts a third more than a 3-credit one. Courses taken pass/fail or withdrawn from are left out.
An unweighted GPA treats every course the same, up to 4.0. A weighted GPA, common in US high schools, adds extra points for harder courses, usually 0.5 for honors and 1.0 for AP, IB or dual-enrollment courses, so it can go above 4.0. Colleges often recalculate GPAs their own way, so report the version your school prints on your transcript.
Most US colleges treat an A+ as 4.0, the top of the scale. Some schools give it 4.33. The calculator uses 4.0 by default; you can change it under Advanced settings.
It depends on your school's scale. On the common plus/minus scale, 93–100 is an A (4.0), 90–92 an A− (3.7), 87–89 a B+ (3.3) and so on. On a simple 10-point scale, 90–100 is an A, 80–89 a B, 70–79 a C and 60–69 a D. Both scales are in the calculator, along with Ontario's OMSAS table, where 90–100 is 4.0 and 85–89 is 3.9.
There are two common methods. Credential evaluators such as WES use conversion tables: they match each grade to the US grade with the same meaning, then average the course grades by credits. German universities use the modified Bavarian formula, x = 1 + 3 × (Nmax − Nd) ÷ (Nmax − Nmin), where Nmax is the best grade, Nmin the lowest pass and Nd your grade. This tool shows both. They can differ by several tenths, because the formula assumes every part of a scale is used equally, while tables allow for systems like the UK's or France's, where top marks are rare.
It depends on the university. Many US graduate schools ask for an official evaluation from WES, ECE or another NACES member. German universities use the Bavarian formula, often through uni-assist. Ontario universities apply for medicine through OMSAS, which uses its own tables. Always check the admissions pages of the schools you're applying to; treat these conversions as a close estimate, not an official result.
The US scale stops at 4.0, so every conversion does too. That's why a UK First, a German 1.0 and a French 16 all land on 4.0 even though they're not equally common. Conversion tables compress the top of scales where the highest marks are rarely awarded.
Your new GPA is a credit-weighted average of your old grades and your new ones, so the more credits you've completed, the more new credits it takes to move it. To find the average you need, take the target times all your credits, subtract your current GPA times the credits you've done, and divide by the credits still to come. The Reaching a Target tab does this and shows combinations of grades that get you there.
Pass/fail and withdrawn courses usually don't affect GPA, though passed courses still count toward credits. A failed graded course usually counts as 0 points. Schools differ on repeated courses: some replace the old grade, others average both, so check your school's policy.

The disclaimer that actually matters: grading practices vary between universities in the same country, and even between departments. The conversions here follow commonly used tables and are meant as a careful estimate. For applications, the official evaluation or the university's own table is what counts.
How GPA works: calculating GPA by hand, weighted and unweighted GPA, A+ values, percentage to GPA scales, converting international grades with WES-style tables and the modified Bavarian formula, and raising your GPA.
