Calculate your semester or cumulative GPA instantly. Add your courses, credit hours, and grades to see where you stand.
A good grade in a 4-credit course impacts your GPA more than in a 2-credit course.
It's easier to maintain a high GPA than to raise a low one. Begin each term with focus.
Professors notice students who seek help. It can make the difference between a B+ and an A.
WriteScholar helps you write better papers, find citations, and study smarter with AI-powered tools.
Add your courses, credit hours, and letter grades to instantly compute your semester GPA. Add multiple semesters to compute your cumulative GPA. Supports standard 4.0 scale, weighted scales (AP/honors +0.5), and unweighted scales. No sign-up.
Click "Add Course" and enter the course name, credit hours, and your letter grade. Most US colleges use 3-credit courses for standard classes; lab courses are often 1 credit; senior thesis or capstone classes can be 6.
Add each course separately. The GPA recalculates live as you add courses, so you can see how a single grade pulls your average up or down.
The headline number is your unweighted GPA on a 4.0 scale. A 3.5 is "B+/A-" territory; a 3.7 is solid A-; a 4.0 is straight As.
Click "Add Semester" to layer in past terms. Cumulative GPA averages across all credit hours, not all semesters, a heavy 18-credit semester pulls more than a light 12-credit semester.
Halfway through finals, plug in your current expected grades. Tells you if you're on track for honors (3.5+ at most schools) or scholarship retention (often 3.0).
Most grad programs care about cumulative GPA + last-60-credits GPA. Add only your last 60 credits separately to see what an admissions committee will actually look at.
Will dropping a 3-credit class with a current C+ help or hurt? Plug in both scenarios and compare.
Most merit scholarships require a 3.0 or 3.5 minimum. Run your projected GPA before declaring a course load to make sure you're safe.
High schools use weighted GPAs (AP/honors +0.5 or +1.0). Colleges use unweighted. Use both modes to see how an admissions reader will compare you.
GPA isn't universal. Here's how the same student's performance translates across the most common systems.
| Letter / Tier | US 4.0 | US % | UK | India % | Australia |
|---|---|---|---|---|---|
| A / A+ | 4.0 | 93-100 | First (1st) | 90-100 | HD |
| A- | 3.7 | 90-92 | First (1st) | 85-89 | HD |
| B+ | 3.3 | 87-89 | Upper Second (2:1) | 75-84 | D |
| B | 3.0 | 83-86 | Upper Second (2:1) | 65-74 | D |
| B- | 2.7 | 80-82 | Lower Second (2:2) | 60-64 | C |
| C+ | 2.3 | 77-79 | Lower Second (2:2) | 55-59 | C |
| C | 2.0 | 73-76 | Third (3rd) | 50-54 | P |
| D / Pass | 1.0 | 60-66 | Pass / Ord. | 40-49 | P (cond.) |
| F | 0.0 | <60 | Fail | <40 | F |
4 credits of an A and 1 credit of a C is NOT a B. Weight matters: (4×4.0 + 1×2.0) / 5 = 3.6, not 3.0. Most calculators do this automatically; some students miscalculate by hand.
Most colleges recalculate using their own scale (often unweighted). Reporting "5.0 weighted" doesn't impress them, they want the unweighted equivalent (typically 4.0).
Pass/fail courses don't count toward GPA at most schools. A "Pass" doesn't add or subtract grade points. Set the credit to 0 in the calculator or omit the course.
Some schools replace the original grade; some average both. Check your registrar's policy. The calculator shows the math, but you have to apply your school's rule.
Semester GPA = this term only. Cumulative GPA = all terms combined. Many students celebrate a 4.0 semester without realizing their cumulative is still 3.4.
A 79.4% might round up to 80% (B-) at one school, stay 79% (C+) at another. Always check before assuming you know your final GPA.
Multiply each grade point by credit hours, sum, divide by total credits. NOT a simple average of grade points.
New grade = (current grade × current weight) + (final score × final weight). Solve for final score given target.
Cumulative GPA = sum of (semester GPA × credits) ÷ total credits. NOT the average of semester GPAs.
Honors at 3.5 means submit at 3.6, not 3.5 exactly. Buffer protects you if a grade is recalculated downward.
A "C" in calc as a freshman hurts less than a "C" senior year for the same reason: it averages over more credits in cumulative GPA. Take the hard ones early when bad grades cost less proportionally.
Plug in your current grades to see your projected GPA. Tells you whether retention or graduation honors is at risk before grades are locked in.
A bad single test grade panics most students. Plug everything in to see the actual semester impact, usually less than feared.
Some schools allow re-taking a course to replace the original grade. The "replaced" course still appears on the transcript with both grades, only the higher one counts toward GPA. Worth using on a C, less so on a B.
