Understanding the GPA Calculator
Your GPA condenses a semester of grades into a single number, but calculating it means weighting each course by its credit hours — and weighting honors or AP classes higher still. This calculator handles all of that: enter each course's grade, credits, and type, and it computes your semester GPA, with an option to roll in your previous record for a cumulative figure.
Students use it to project a semester before grades are final, to see how one class will move their average, or to confirm a registrar's number. Support for weighted course types and a 4.0 or 5.0 scale means it works for standard transcripts and weighted honors systems alike.
Getting a result
- Choose the 4.0 or 5.0 GPA scale.
- Add each course with its grade, credit hours, and type (regular, honors, AP, or IB).
- Optionally enter your previous GPA and total credits for a cumulative result.
- Read your semester GPA, cumulative GPA, total credits, and a grade breakdown.
Quality points, credits, and how this tool weights honours courses
A GPA is a credit-weighted average, not a plain one. Each course contributes quality points equal to its grade point times its credit hours, those are summed, and the total is divided by total credits. That weighting is why a poor grade in a four-credit course damages an average more than the same grade in a one-credit elective.
Course type applies a multiplier to the quality points: regular counts at 1.0, honours at 1.05, and both AP and IB at 1.1. Be aware that this is not the convention most American schools use. The widespread approach is additive — typically half a point for honours and a full point for AP, so an A in an AP class becomes 5.0 on a 4.0 scale. Here it becomes 4.4.
That difference is material, so treat the weighted figure as this tool's own scale rather than one your school will recognise. If you need a number that matches an official transcript, check your institution's published method — practice varies not just between countries but between districts.
- A 4-credit regular course at A (4.0) plus a 4-credit honours course at B+ (3.3) gives 29.86 quality points over 8 credits: a GPA of 3.732.
- An A in an AP course scores 4.4 here, where the common additive convention would give 5.0.
- Adding a prior GPA and its credit total blends both into a cumulative figure, weighting each by its credits.
Reasons to use it here
- It weights honors, AP, and IB courses above regular ones, reflecting how weighted GPAs are actually calculated rather than treating every course equally.
- It supports both the 4.0 and 5.0 scales and computes a cumulative GPA when you supply prior credits.
- It shows total quality points and a per-grade breakdown, so you can see exactly how the average was built.

Why GPAs resist comparison
Almost nothing about GPA calculation is standardised. Scales differ — 4.0 is common in the United States, 10-point scales appear in India, and percentage or classification systems are used across Europe. Grade-to-point mappings differ, some institutions ignore plus and minus modifiers entirely, and policies on retaken courses, pass/fail credits, and transfer credit all vary.
Weighted and unweighted figures serve different purposes and are not interchangeable. Unweighted caps at 4.0 and compares grades directly; weighted exceeds it to credit course difficulty. Many universities recalculate applicants' GPAs to their own formula precisely because the incoming numbers are not comparable, which is worth remembering before reading much into a decimal place.
Use this to project where a term is heading, to see how much a particular grade would move your average, or to work out what you need in a final. For anything official — an application, a scholarship threshold, an eligibility rule — the registrar's calculation is the one that counts.
Frequently Asked Questions
How is GPA calculated?
Each course's grade is converted to grade points, multiplied by its credit hours (and a weight for honors or AP), to give quality points. GPA is the total quality points divided by the total credits, so higher-credit courses count more toward the average.
What is the difference between weighted and unweighted GPA?
An unweighted GPA treats every course on the same scale, while a weighted GPA gives extra points to harder courses like honors, AP, or IB. This calculator applies those weights when you mark a course's type, raising its contribution to the average.
How do I calculate my cumulative GPA?
Enter your previous cumulative GPA and the total credits it covers, alongside this semester's courses. The calculator combines the prior quality points with the new ones to produce an updated cumulative GPA across all credits.
What GPA scale should I use?
Use the scale your school reports on — 4.0 is the most common unweighted scale, while 5.0 scales are often used where weighted honors and AP grades can exceed 4.0. The toggle lets you match whichever your institution uses.
