Add a row per course, set the letter grade and credit hours, and your GPA computes live on the standard US 4.0 scale. Credits weight the result — a B in a four-credit course pulls your average more than an A in a one-credit seminar helps it, which is exactly the arithmetic this calculator makes visible.
Frequently asked questions
How is GPA calculated?
Each grade maps to points (A = 4.0, B+ = 3.3, …). Multiply each course's points by its credit hours, sum, and divide by total credits. This calculator shows the running grade-point and credit totals so you can check against your transcript.
Does A+ count above 4.0?
Usually not — most US institutions cap at 4.0, which is what this calculator does. Some schools award 4.3 for A+; if yours does, your registrar's number wins.
How do I work out what GPA I need this term?
Add rows for this term's courses and try grade combinations until the overall number hits your target — including your existing credits as one summary row (grade closest to your current GPA, credits = completed hours) gets you close.
