🧮 Calculation
Standard GPA Grade Scale (4.0)
| Letter | Grade points | Letter | Grade points |
|---|---|---|---|
| A | 4.0 | C | 2.0 |
| A− | 3.7 | C− | 1.7 |
| B+ | 3.3 | D+ | 1.3 |
| B | 3.0 | D | 1.0 |
| B− | 2.7 | D− | 0.7 |
| C+ | 2.3 | F | 0.0 |
A B+ is worth 3.3 grade points — a third of the way from B (3.0) to A (4.0). Many schools skip the − grades (A, B+, B, C+…) or use slightly different values; always confirm your school's official scale, and check whether it rounds. High schools that weight AP, IB and Honors classes typically add +1.0 (so an A in AP Biology earns 5.0), which the calculator above applies per course via the AP/Honors checkbox.
How to Calculate GPA — The Formula
Each course earns quality points = credits × grade points. Example: an A (4.0) in a 3-credit course earns 12 points; a B (3.0) in a 4-credit course earns 12 points. Add every course's quality points, divide by total credits — that's your GPA. Cumulative version: add previous GPA × previous credits to your quality points and previous credits to your total credits before dividing. Worked example below in the calculator's step-by-step breakdown.

Pro Tips for GPA Calculation
- Credits are the multiplier that matters: an A in a 4-credit class pulls your GPA four times as hard as an A in a 1-credit seminar. Always check the credit hours on your schedule, not just the grades.
- Pass/Fail courses usually don't count: most schools exclude Pass grades from GPA math entirely — leave them out of the calculator.
- Repeated courses: many schools replace the old grade for repeats (grade forgiveness); some average both attempts. Your registrar's policy decides which number goes in.
- Weighting varies by school: some high schools add +1.0 for AP/IB and +0.5 for Honors; some cap at 5.0, others at 6.0. This calculator applies the common +1.0 AP/Honors boost per ticked course.
- Scenario-test your semester: temporarily set every course to the grade you're hoping for, read the cumulative result, then set realistic grades — the gap tells you exactly where to focus study time.
