GPA calculator
Enter your courses, credits and letter grades, and get your semester GPA on the 4.0 scale, weighted for Honors and AP if your school does that, plus your running cumulative.
Guide
How to use it
- List each course with its credit hours (usually 3 or 4 in college, 1 per class in many high schools, any consistent unit works).
- Pick the letter grade you earned. Plus and minus grades step by 0.3 points.
- Mark Honors or AP/IB classes and toggle Weighted if your school weights, Honors +0.5, AP +1.0 is the common scheme.
- Add your prior cumulative GPA and its total credits to roll this semester into your overall number.
Examples
Reading the scale
A and A+ both count 4.0 on the standard scale (A+ above 4.0 exists at some schools, not here). An A- is 3.7, the gap between A and A- across a schedule is about 0.3 of GPA.
The Dean’s List band at many colleges, and the "3.5+" line common on internship postings. One B+ among A’s keeps you here comfortably.
A weighted GPA above 4.0 signals AP-heavy scheduling to admissions, but colleges usually recalculate unweighted for comparison. Know both numbers, this tool shows either with one toggle.
Method
How it works
GPA is a credit-weighted average: each grade’s points times the course credits, summed, divided by total credits, so a 4-credit class moves the number more than a 1-credit elective. The standard points map A=4.0 down to F=0 with 0.3 steps for plus and minus.
Weighted mode adds 0.5 (Honors) or 1.0 (AP/IB) to each affected grade’s points, the most common US high school scheme, though districts vary, and cumulative GPA merges prior credits with this semester’s at their respective weights.
FAQ
Frequently asked questions
Is an A+ worth more than an A?
On the standard 4.0 scale, no, both are 4.0. Some institutions award 4.3 for A+, if yours does, its transcript will say so, and its number will differ slightly from this one.
How do pass/fail classes count?
Usually not at all: a P earns credits but no grade points, so it neither helps nor hurts GPA. Leave pass/fail classes out of the calculation.
What GPA do colleges want?
Selective admissions cluster above 3.7 unweighted, solid state programs commonly mid-3s, but rigor (those AP courses) reads alongside the number, not beneath it.
How much can one semester move my cumulative?
Depends on the credit ratio: with 90 prior credits, a 15-credit semester moves the cumulative at most about 0.15 either way. The prior-GPA fields show it exactly.
Weighted or unweighted on applications?
Report what the form asks for, and expect colleges to recalculate to their own scheme anyway. Class rank often uses weighted, scholarships often specify unweighted.
Does this work for UK degrees?
No, UK classifications (First, 2:1) are a different system. This page speaks US GPA natively, converting between the two is an admissions office’s judgement call, not a formula.
