School Credit Calculator
Students searching for a school credit calculator are usually asking one of four questions: what is my GPA this semester, what is my cumulative GPA now, what grades do I need to reach my target, or how many credits have I earned. This tool answers all four on one page, weighting every course by its credit hours exactly the way registrars compute it.
Add one row per course: the grade you earned and its credit hours. The tool is pre-filled with a three-course example.
Semester GPA
0.00
Uses the standard US unweighted 4.0 scale (A = 4.0 through F = 0.0, with plus/minus values). Your school’s scale may differ; check your handbook before using the number officially.
Quick Answer
Three courses, an A (4 credits), a B+ (3 credits) and an A- (3 credits), earn 37.0 quality points over 10 credits for a semester GPA of 3.70, in Dean's List range. Folded into a 3.20 record over 45 credits, the new cumulative GPA is 3.29. The calculator above is pre-filled with these exact figures.
Key takeaways
- GPA is a credit-weighted average: each course contributes its grade points times its credit hours, and the total is divided by total credit hours. A 4-credit B moves the needle twice as much as a 2-credit A.
- The target planner solves the cumulative formula backward. If the required average comes out above 4.0, the tool says the target is not possible instead of inventing a number.
- This calculator uses the unweighted US 4.0 scale, with A+ counted as 4.0. Weighted scales that add bonuses for honors and AP courses need their own conversion.
- An F still counts its credit hours in the denominator at 0.0 points, which is why one failed course drags a GPA down so hard.
- Pass/fail courses are normally excluded from GPA math. Leave them out of the GPA tabs and count their credits in the credit counter.

The four questions this calculator answers
Semester GPA is the term workhorse: add a row per course, pick the letter grade, enter the credit hours. It computes total quality points, total credits, the GPA and an academic-standing indicator. Cumulative GPA folds a new semester into your existing record: enter your current GPA and completed credits plus the new semester's figures. Target GPA planner answers what you need from here: given your record and remaining credits, it tells you the average you must earn, and says plainly when the target is mathematically impossible. Credit counter is the straight total: credit hours per course, summed, for students tracking progress toward graduation.
Switching modes hides the previous results so a semester GPA can never be mistaken for a cumulative one. Results stay hidden until you click Calculate, and Reset restores the worked example in every mode.
The GPA formula, without the mystery
Every registrar computes it the same way: quality points for a course equal its grade points times its credit hours, and the GPA is total quality points divided by total credit hours attempted. Cumulative GPA is the same formula stretched across every term: total quality points from all terms divided by total credit hours from all terms. The target planner simply solves that equation for the unknown semester average.
If you think in conversions rather than courses, the credit hours to credit points calculator handles the credits-to-points step on its own.
The 4.0 scale this tool uses
The standard US unweighted scale assigns 4.0 to both A+ and A, then steps down by thirds: A- is 3.7, B+ is 3.3, B is 3.0, and so on to F at 0.0. This matches the scale most American high schools and colleges publish, and it is the scale behind every number on this page.
Two honest caveats. First, some schools count A+ as 4.3 and some use different plus/minus values; if an official figure matters for a scholarship or probation decision, your handbook outranks this page. Second, weighted scales add bonuses, often +0.5 for honors and +1.0 for AP or IB, so GPAs can exceed 4.0 there. Students in AP courses should check the AP class GPA calculator for the weighted version, and note that some universities publish entirely custom scales, which is why a school-specific tool like the Stanford GPA calculator exists.
Worked examples from the pre-filled tool
Semester GPA. A (4 credits), B+ (3 credits), A- (3 credits): quality points are 16.0 + 9.9 + 11.1 = 37.0 over 10 credits, GPA = 3.70, Dean's List range. Click Calculate in the Semester tab to reproduce it.
Cumulative GPA. A 3.20 record over 45 credits plus the 3.70 semester over 10 more: (3.20 x 45 + 3.70 x 10) / 55 = 181 / 55 = 3.29, good standing. Notice how one strong semester moves a 45-credit record only modestly; that is the weight of history in the denominator.
Target planner. At 2.80 over 60 credits with 30 credits left, reaching a 3.00 needs (3.00 x 90 - 2.80 x 60) / 30 = 102 / 30 = 3.40 across the remaining credits. The tool's aim-for row names the highest qualifying letter first, so it reads "Roughly A+ or better"; treat that as shorthand for "average 3.40", since an A- average of 3.70 clears the bar too.
Credit counter. Three courses at 4, 3 and 3 credits: 10 credits total across 3 courses counted.
What competing calculators miss
- gradeandgpacalc.com covers semester, cumulative and weighted GPA with a full per-course breakdown table and a standing scale, which is the strongest single-semester tool in the results. It does not solve the backward question: what average do I need from here.
- gpacalculator.net loads 90 university-specific scales plus an A+ = 4.33 option and per-semester tracking, excellent for scale accuracy. Its planner stops at cumulative projection; there is no target-solver with a not-possible verdict.
- freegpacalculator.net adds weighted mode (+0.5 honors, +1.0 AP/IB, max 5.0) and a cumulative tab. No target planner, no credit counter for graduation tracking.
- simply-gpa.com offers 11 grading scales and a cumulative record with a trajectory chart, but it is an app-first product; the web experience is a feature tour rather than a working planner.
- callculator.cc emphasises which course matters most for the GPA, a genuinely useful angle, but only handles two representative courses at a time.
- getmygpa.app explains the formula clearly and offers a weighted 5.0 mode. No target solving, no credit totals.
- The gap this page fills: four modes on one page where rivals offer one or two, a target planner that solves the cumulative formula backward and admits when the math is impossible, a plain credit counter for graduation tracking, and the full 4.0 scale printed on the page so students are never guessing what an A- is worth.
Honest limits: what the tool does not know
Three things vary by school and this tool cannot know them. First, the grade scale: A+ as 4.0 is the standard unweighted convention, but your school may differ. Second, retake policy: some schools replace a retaken grade, others average both attempts, which changes what "raise my GPA fastest" means for you. Third, GPA hours versus earned credits: some transcripts list them separately, and the cumulative tab wants the hours figure. The standing labels (Dean's List range at 3.5, good standing at 2.0) are the common conventions, not your catalog's rule. For anything official, the registrar's number wins.
Frequently asked questions
Each course contributes its grade points times its credit hours, called quality points. Add those up and divide by total credit hours attempted. A 4-credit B counts more than a 2-credit A, and that weighting is the whole point of the credit-hours system.
Unweighted uses the standard 4.0 scale for every course, so the maximum is 4.0. Weighted adds a bonus, often +0.5 for honors and +1.0 for AP or IB courses, so GPAs can exceed 4.0. This calculator uses the unweighted 4.0 scale; if your school weights, convert to its values first.
Yes, and that surprises people. An F is 0.0 grade points but its credit hours still count in the denominator, so it drags the GPA down hard. Retaking helps a lot only if your school replaces the grade; many schools average the two attempts instead.
Usually they are excluded from the GPA calculation, contributing no grade points either way, but they still count toward earned credit totals. Leave pass/fail courses out of the GPA tabs and count their credits in the credit counter.
It names the highest letter grade whose point value clears the required average, scanning from A+ downward, so any feasible target shows "Roughly A+ or better". Read it as shorthand for the required average itself: needing 3.40 means averaging 3.40, which an A- average of 3.70 also satisfies.
Most schools set it around 3.5 for the term, sometimes higher and sometimes with a minimum credit load such as 12 graded hours. The standing indicator here uses 3.5 as the Dean's List range and 2.0 as good standing, but your school's catalog is the authority.
The math favors two moves: retake courses where your school replaces low grades, since a replaced F is the biggest single swing available, and earn high grades in remaining credits. Every future A dilutes past damage, but the dilution is slow once you have many credits banked, which the target planner shows exactly.
Yes. Enter classes, grades and credits the same way. Just confirm whether your school reports weighted or unweighted GPA before using the number anywhere official, since high schools vary more in their scales than colleges do.
