GPA Calculator
Calculate your GPA from course grades and credit hours, on any grading scale.
GPA
4.00
Total credits

Uses a standard 4.0 grading scale. Check with your institution if it weights grades differently.
Calculate your GPA by entering each course's letter or numeric grade along with its credit hours — the tool weights each grade by credits and averages across whatever grading scale you're on, whether that's a standard 4.0 scale or another system your school uses.
Add or remove courses freely to model a full semester, a single term, or see how one more class would move your cumulative GPA.
How weighting by credit hours changes the answer
GPA is a weighted average, not a plain one. A 4-credit course counts twice as much as a 2-credit course, so an A in a lab-heavy major course moves your GPA far more than an A in a one-credit elective.
Worked example: an A (4.0) in a 4-credit course and a C (2.0) in a 1-credit course gives (4×4 + 2×1) ÷ 5 = 3.6 — not the 3.0 a simple average of the two grades would suggest.
| Letter | Typical points | Percentage band |
|---|---|---|
| A / A+ | 4.0 | 93–100% |
| A− | 3.7 | 90–92% |
| B+ | 3.3 | 87–89% |
| B | 3.0 | 83–86% |
| B− | 2.7 | 80–82% |
| C | 2.0 | 73–76% |
| D | 1.0 | 63–66% |
| F | 0.0 | Below 60% |
Bands vary by institution — check your own handbook, as some schools don't use plus/minus grades at all.
Working out what you need next semester
- Enter every course completed so far to get your current cumulative GPA and total credits.
- Multiply your target GPA by the total credits you'll have after next semester.
- Subtract the grade points you already hold (current GPA × current credits).
- Divide the remainder by next semester's credits — that's the average grade point you need.
- If the answer is above 4.0, the target isn't reachable in one semester; recalculate over two.
Frequently asked questions
- How is GPA calculated from letter grades?
- Each letter grade converts to a grade point (e.g. A = 4.0), multiplied by that course's credit hours, then the sum of all grade points is divided by total credit hours.
- Can I use this for a non-4.0 grading scale?
- Yes — set the scale to match your institution's system, and grade-point conversions adjust accordingly.
- Does this calculate cumulative GPA across multiple semesters?
- Enter every course from every semester you want included, along with its credit hours, and the result is your cumulative GPA across all of them.
- What's the difference between weighted and unweighted GPA?
- Unweighted caps every course at 4.0. Weighted GPA (common in US high schools) gives AP or honours courses a 5.0 scale, so a weighted GPA above 4.0 is possible. This tool calculates a credit-hour weighted average, which is a different thing again.
- How much can one bad grade hurt?
- Less than you'd fear early on, more than you'd like later. A single C in your first semester is easy to dilute; the same C in your final semester barely moves a cumulative GPA built from 100+ credits — which cuts both ways for recovery.
- Do pass/fail courses count?
- Usually they earn credit but carry no grade points, so they're excluded from the GPA calculation entirely. Leave them out unless your institution says otherwise.
