Two calculators in one page: a simple grade calculator for averaging test scores and assignments, and a full GPA calculator for letter grades and credit hours on a 4.0, 5.0, or percentage scale. Also includes a final grade calculator and a weighted grade calculator — everything you need to work out your grades, free and instant.
Not sure how GPA actually works, what "credit hours" mean, or how to find your GPA of grades by hand? Scroll down — every section below explains the exact math in plain language, with a worked example.
Need a quick grade calc for a single class — just averaging test scores, quiz marks, or assignments? Use this simple grade calculator. No letter grades, no credit hours, just your scores in and an average out.
This grading calculator works for any set of numbers — homework scores, test percentages, quiz marks, or lab grades. For a grade that factors in course credit hours across a full term, use the GPA Calculator below instead. For a grade split across categories like homework vs. exams, use the Weighted Grade Calculator further down.
Use this GPA calculator to work out your grade point average from your course grades and credit hours. Add each course, pick a letter grade, enter the credit hours (or just use Easy Mode below if you don't know them), and this grade calculator does the rest — no sign-up required.
| Course | Grade | Credits | Quality Pts |

This is the part that confuses most people the first time they use a GPA calculator — here's what it actually means.
Credit hours are just a weight for each course — a number that says how big or how important that course is compared to your other courses. Most schools print this number on your transcript, timetable, or course outline, usually written as "3 credit hours" or "Cr. Hrs: 4" next to the subject name.
Why does it matter? Because not every course should count the same. A full subject you attend three or four times a week for a whole semester should pull your GPA more than a one-day workshop would. Credit hours are how the math reflects that — a 4-credit course with a strong grade lifts your GPA more than a 1-credit course with the same grade.
Turn on Easy Mode in the calculator above. It skips credit hours entirely and simply averages all your grades equally — a simpler, close-enough estimate that works fine if every one of your subjects is roughly the same size, or if you just want a quick number without digging through paperwork.

Wondering how to work out a GPA by hand, or how to find the GPA of grades without a calculator? Here's exactly how this GPA calculator computes your grade point average, step by step.
Say you earned an A (4.0) in a 3-credit course and a B (3.0) in a 4-credit course. How do you calculate GPA from that?
(4.0 × 3) + (3.0 × 4) = 12 + 12 = 24 total quality points.
24 ÷ (3 + 4) = 24 ÷ 7 = 3.43 GPA.
This is exactly how to compute a GPA no matter how many courses you're averaging — the calculator above automates this so you don't have to do it by hand every semester.
An unweighted GPA treats every course the same, capping out at 4.0 regardless of difficulty. A weighted GPA gives extra grade points to harder courses — honors, AP, or IB classes — which is why weighted GPAs can go above 4.0, often up to 5.0. If your school offers advanced courses, check whether your transcript reports a weighted or unweighted number before comparing it to a target.
Your semester GPA only includes courses from one term. Your cumulative GPA (sometimes called CGPA) averages every course you've ever taken, across every semester, weighted by each course's credit hours. The calculator above works for either — just enter the courses from whichever period you want to measure: one semester for a semester GPA, or every course so far for your CGPA. For a calculator built specifically around multi-semester tracking, try our dedicated CGPA Calculator.
Use this final exam calculator to figure out what you need on your final to hit a target grade in the course. Enter your current grade, your goal, and how much the final is worth — three numbers, one clear answer.
Once you know where you stand, here's what actually moves the number.
Since credit hours act as a weight, a strong grade in a 4-credit course lifts your GPA more than the same grade in a 1-credit one. Focus extra study time accordingly.
Don't wait until exam week to find out what score you need — plug your numbers into the Final Grade Calculator above as soon as midterms are posted.
Many schools let you retake a course and replace the old grade. A single D or F pulls your GPA down disproportionately — check your school's retake policy.
Re-run the calculator above each term with your updated courses — catching a slipping average early gives you more time to recover it.
Most grading scales mix categories like homework, tests, and a final exam, each worth a different share of your total. This weighted grade calculator — and grading calculator — adds them up correctly so you know your real overall grade.
| Category | Score | Weight | Contribution |
|---|
College GPA works on a 4.0 scale at most US universities: each course grade converts to grade points (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0), multiplied by credit hours, then averaged across courses. Semester GPA covers one term; cumulative GPA covers your entire degree. Some schools also use weighted GPA, which awards extra points for honors or AP courses.
Not sure what a letter grade is worth, or what the highest GPA possible is? Here's the standard 4.0 GPA scale and grading scale used by most high schools, colleges, and universities.
| Letter Grade | Percentage Range | 4.0 Scale | 5.0 Scale (Weighted) |
|---|---|---|---|
| A+ | 97–100% | 4.0 | 5.0 |
| A | 93–96% | 4.0 | 5.0 |
| A- | 90–92% | 3.7 | 4.7 |
| B+ | 87–89% | 3.3 | 4.3 |
| B | 83–86% | 3.0 | 4.0 |
| B- | 80–82% | 2.7 | 3.7 |
| C+ | 77–79% | 2.3 | 3.3 |
| C | 73–76% | 2.0 | 3.0 |
| C- | 70–72% | 1.7 | 2.7 |
| D+ | 67–69% | 1.3 | 2.3 |
| D | 63–66% | 1.0 | 2.0 |
| D- | 60–62% | 0.7 | 1.7 |
| F | Below 60% | 0.0 | 0.0 |
On a standard unweighted scale, the highest GPA possible is a 4.0. Weighted scales — commonly used for honors, AP, or IB courses — can push the highest GPA possible above 4.0, often up to 5.0, since those courses are assigned extra grade points.
A D (roughly 60–69%) is generally a passing grade at most institutions, though it's usually the lowest passing mark and may not count toward major or prerequisite requirements — always confirm with your specific school's policy.
