CALCULATOR · SCHOOL · GRADES
English A, Math B+, Science A, History B, Art A — that is a 3.66 GPA on the standard 4.0 scale. Enter up to six courses, flip the weighted toggle for honors classes (+0.5 each), and get your GPA with its letter equivalent in one click. Built for middle school’s reality: no AP courses, plenty of +/− grades, and cutoffs that actually matter.
Pick a letter grade for each course — leave rows blank you do not take — and check Honors for any honors-level class. Turn the weighted toggle on to add +0.5 per honors course (the common middle-school convention). The calculator averages only the courses you entered and shows the unweighted base alongside.
GPA = sum of grade points ÷ courses counted. Each letter maps to the 4.0 scale (A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0 … F = 0.0), blank rows are ignored, and the average divides by the courses you actually entered. The default: 4.0 + 3.3 + 4.0 + 3.0 + 4.0 = 18.3 ÷ 5 = 3.66 — a B+/A− average. Turn the weighted toggle on with honors courses checked and each honors class gains +0.5 before the averaging.
Setup: English A, Math B+, Science A, History B, Art A, Course 6 left blank, weighted toggle off.
Convert to points. A → 4.0, B+ → 3.3, A → 4.0, B → 3.0, A → 4.0. The B+ at 3.3 — not 3.5, not 3.0 — is the grade most students misprice; the +/− steps are uneven by design.
Add and divide. 4.0 + 3.3 + 4.0 + 3.0 + 4.0 = 18.3; five courses entered, so 18.3 ÷ 5 = 3.66 GPA. The blank sixth row divides by 5, not 6 — an empty row never drags the average down.
Branch — weighted, 3 honors courses (English, Math, Science): toggle weighted on and check Honors on the first three courses: 4.5 + 3.8 + 4.5 + 3.0 + 4.0 = 19.8 ÷ 5 = 3.96. The same grades, three honors labels, and the GPA climbs three-tenths — which is exactly why magnet programs ask which version you are reporting.
Branch — the straight-B student: five B’s: 5 × 3.0 = 15.0 ÷ 5 = 3.00 GPA — the anchor point of the scale. Every A above 3.00 pulls up by 0.20 per course (on five courses); every C pulls down by 0.20. The default 3.66 sits 0.66 above it: three A’s minus the B and B+ drag.
| Output | Formula | What it means |
|---|---|---|
| Grade points | letter → 4.0 scale (A = 4.0 … F = 0.0) | 18.3 at the defaults — the raw sum before averaging. |
| GPA | grade points ÷ courses counted (+0.5 per honors course if weighted) | 3.66 at the defaults — the headline number. |
| Unweighted base | grade points ÷ courses counted, honors ignored | 3.66 at the defaults — always shown alongside, so both versions are visible. |
| Letter equivalent | GPA mapped back to a letter range | B+ range at the defaults — a plain-English reading of the number. |
| Courses counted | rows with a grade selected | 5 at the defaults — blank rows never dilute the average. |
Grading scales vary by school: some districts drop the +/− (a B+ counts as a flat 3.0), some weight honors at +1.0 instead of +0.5, and some do not weight middle-school honors at all — match your school’s scale before reporting this anywhere official. The calculator weights every course equally; schools that weight by credit hours will differ slightly. Pass/fail and audit courses are typically excluded from GPA — leave those rows blank here. This is a planning tool for students and families, not an official transcript.
Bright Side Kit. "Middle School GPA Calculator: Weighted & Unweighted." https://brightoolbox.com/middle-school-gpa-calculator/ Accessed October 23, 2026.Data sourcesUnweighted caps at 4.0: an A is 4.0 no matter the course level. Weighted rewards harder courses — this calculator adds +0.5 per honors course when the toggle is on, so the same A/B+/A/B/A report card reads 3.96 weighted vs. 3.66 unweighted. Always ask which version a program wants; they are different numbers.
Yes, on the standard scale. A B+ is 3.3 and a B is 3.0 — a 0.3 gap per course, or 0.06 of GPA on a five-course schedule. An A− (3.7) costs 0.3 versus a straight A. The steps are uneven (B+ to A− is 0.4), which is why eyeballing grades misleads — run the numbers.
Many middle-school magnet and advanced-academy programs set cutoffs around 3.0–3.5, and they usually specify weighted or unweighted — a 3.66 unweighted can clear a 3.5 bar that the same transcript’s weighted 3.96 sails past. Check the program’s handbook; “GPA” alone is ambiguous.
Usually yes. Most schools average every course that carries a letter grade — art, PE, music, world language — into the GPA. That is why the default example includes Art: dropping it would change the 3.66. Pass/fail courses are the exception; leave those rows blank.
Exclude them. Pass/fail, audit, and ungraded courses do not enter the GPA at most schools — select “— choose —” (blank) for those rows and the calculator ignores them. Counting a “Pass” as an A would inflate the result dishonestly.
Yes. With the +0.5 honors convention, all honors A’s average 4.5 — above the 4.0 ceiling. (High-school AP weighting at +1.0 can push it to 5.0.) Unweighted GPA can never exceed 4.0. If a form asks for GPA “on a 4.0 scale,” it almost always means unweighted.
