Work out your GPA on the 4.0 scale — weighted or unweighted — combine it with your cumulative GPA, and find out exactly what you need on the final exam to hit your target grade.
| Target grade | Overall % | You need on the final |
|---|
Two questions every student asks, answered on one page: "What's my GPA?" and "What do I need on the final?" Enter your courses and letter grades to get your GPA on the standard 4.0 scale — weighted or unweighted — and switch tabs to find the exact final-exam score that gets you to the grade you want.
Everything computes instantly as you type, your entries auto-save in your browser so they're still here next visit, and nothing is uploaded anywhere — your grades are your business.
| A | A− | B+ | B | B− | C+ | C | C− | D+ | D | D− | F |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 4.0 | 3.7 | 3.3 | 3.0 | 2.7 | 2.3 | 2.0 | 1.7 | 1.3 | 1.0 | 0.7 | 0.0 |
Your GPA is the credit-weighted average: each course's grade points are multiplied by its credit hours, summed, and divided by total credits. A 4-credit A pulls your GPA up more than a 1-credit A — that's why the credits column matters.
Many high schools add a bump for harder courses: +0.5 for Honors and +1.0 for AP or IB, so an A in AP Calculus counts as 5.0. Flip the "Weighted" switch and a level column appears next to each course. Schools vary — some cap the bump, some use 6.0 scales — so check your school's policy; this tool uses the most common convention. Colleges almost always recalculate on the unweighted 4.0 scale, which is why the tool shows that number by default.
Already have a GPA from previous semesters? Enter it with the number of credits it covers, and the tool combines it with this semester's courses: (prior GPA × prior credits + new grade points) ÷ total credits. That's exactly how your registrar does it.
The classic end-of-semester math. If your current grade is C, the final is worth w percent of the course, and you want to end at T, the score you need is:
needed = (T − C × (1 − w)) ÷ w
The calculator does this live and gives you a straight answer — including the honest ones: a green "you've already secured it" when even a zero keeps your target, and a red "not mathematically possible" when the target is out of reach at that weight. The table below the result shows what you'd need for every common letter-grade cutoff, so you can decide what's worth studying for.
Enter each class's grade and credits, and the calculator converts letters to grade points (A is 4.0, B is 3.0, and so on) and computes the credit-weighted average. Weighted mode adds the Honors and AP bumps automatically.
Weighted GPAs add a bump for harder courses, commonly +0.5 for Honors and +1.0 for AP or IB, so an A in AP counts as 5.0. Mark each class's level and the calculator applies the right bump, without ever bumping an F.
The final grade tab does exactly this math: enter your current grade, the final's weight, and the grade you want, and it computes the required score, including the honest answers, like when the grade is already locked in either direction.
Combine this term with your prior GPA and credits, and the calculator produces the updated cumulative figure, the number transcripts and applications actually ask for.
Yes. Everything is computed in your browser, so your grades are never uploaded, stored, or seen by anyone but you.
