How GPA is calculated
Grade point average is a credit-weighted average of your grades. Each letter grade maps to a point value on the 4.0 scale (A = 4.0, B = 3.0, and so on, with plus and minus steps). Each course's points are multiplied by its credits to get "quality points," those are summed across all courses, and the total is divided by the total credits. Weighting courses by credits is why a hard-earned A in a four-credit class moves your average more than an A in a one-credit elective. The calculator does this exactly and shows the total credits and quality points behind the result.
Weighted vs. unweighted
Two GPAs come out because schools report both. The unweighted GPA treats every course on the same 4.0 scale regardless of difficulty. The weighted GPA adds a bonus for harder courses — commonly 0.5 for honors and 1.0 for AP or IB classes — to reward students who take a heavier load, which is why weighted GPAs can climb above 4.0. Mark each course's level and the tool computes both, capping the weighted per-course value at 5.0, which is the most common cap. Colleges often recalculate GPA their own way, so having both figures is genuinely useful.
Grades, credits, and levels
Pick each grade from the letter menu — the point value is shown next to it so there's no guessing. Enter credits as your school counts them (many high schools use 1.0 per year-long course; colleges use credit hours, often 3 or 4). Set the level to regular, honors, or AP/IB. Leave the course name blank if you like; it's only there to help you keep track. Start with the four rows provided and add more with the button, or remove any you don't need.
A note on scale differences
There is no single universal GPA scale. Some schools cap A+ at 4.0 and others award 4.3; honors and AP bonuses vary; a few use entirely different systems. This calculator uses the most widely recognized conventions, which match the majority of U.S. high schools and many colleges, but your institution's official policy always wins. Use this for planning, goal-setting, and "what if I get a B in this class" scenarios, and treat your transcript as the record of truth.

Frequently asked questions
How do I calculate my GPA?
Add a row per course with its grade and credits. The tool multiplies each grade's point value by its credits, sums those, and divides by total credits — giving your GPA instantly, both weighted and unweighted.
What's the difference between weighted and unweighted GPA?
Unweighted treats all courses on the same 4.0 scale. Weighted adds a bonus for harder classes — typically +0.5 for honors and +1.0 for AP/IB — so it can exceed 4.0. Mark each course's level and the tool shows both.
Does this match my school's GPA exactly?
It uses standard conventions that match most schools, but scales vary. Your school's official policy and your transcript are authoritative; use this for planning and estimates.
Important
GPA scales vary by school and district. This tool uses a standard 4.0 letter scale with common honors and AP/IB weighting; your school's official policy is authoritative. Confirm the result against your transcript or registrar before relying on it.
