How GPA is calculated

Each letter grade maps to grade points (A = 4.0, B = 3.0, etc.). Multiply each course's points by its credit hours, sum everything, and divide by total credits: GPA = Σ(points × credits) ÷ Σ(credits). Credit weighting is why a B in a 4-credit course pulls your GPA more than an A in a 1-credit lab fixes it.

Standard 4.0 scale

A+ / A4.0C+2.3
A−3.7C2.0
B+3.3C−1.7
B3.0D1.0
B−2.7F0.0

Scales vary: some schools give A+ 4.3, some use 4.33 or percentage-based scales, and Canadian universities differ by province. Check your institution's official conversion — this tool uses the most common US/Canada 4.0 mapping.

GPA milestones that matter

3.5+ typically qualifies for Dean's List and keeps scholarship options open; 3.0 is a common cutoff for grad school applications and many employers' screens; below 2.0 usually triggers academic probation. If you're recovering from a rough semester, remember: the more credits you've completed, the more slowly the cumulative moves — the calculator above shows exactly how much a strong semester shifts it.

Frequently asked questions

How do I raise my GPA fastest?
Retake failed or low-grade courses if your school replaces the grade rather than averaging it (policies differ). Otherwise, load up on courses you can genuinely excel in — the math is purely credits × points.
Do pass/fail courses count?
Usually not in the GPA — a "Pass" gives credits but no grade points at most schools. Leave them out of this calculator (but a "Fail" often does count as 0.0 — check your policy).
What about weighted high school GPAs (5.0 scale)?
Honors/AP classes sometimes add a point (A = 5.0). This calculator uses the unweighted 4.0 scale, which is what most colleges recalculate anyway.
