GPA Calculator

Enter your courses, credit hours, and letter grades to instantly calculate your semester GPA and cumulative GPA on the standard 4.0 scale. Supports plus/minus grading (A+, A, A−, B+, B, B−, and so on) and lets you factor in prior credits to track your overall academic standing.

How GPA Is Calculated

GPA is a weighted average of your grade points across all courses. Each letter grade maps to a numeric value on the 4.0 scale: A/A+ = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, and so on down to F = 0.0. Each grade point value is then multiplied by the credit hours for that course to produce quality points.

The formula is: GPA = Σ(grade points × credit hours) ÷ Σ(credit hours). For example, an A (4.0) in a 3-credit course and a B+ (3.3) in a 4-credit course gives (4.0×3 + 3.3×4) ÷ (3+4) = 25.2 ÷ 7 = 3.60. The calculator runs this math instantly across as many courses as you add.

Cumulative GPA works the same way but spans all semesters. Enter your existing cumulative GPA and total completed credits alongside your current semester courses — the calculator weights them together to show your updated overall standing.

Frequently Asked Questions

Does A+ count as more than 4.0?

At most US colleges and universities, A+ = 4.0 — the same as a plain A. Some high schools and a handful of colleges use a 4.3 scale where A+ earns extra points, but this is not standard. This calculator uses the widely accepted 4.0 ceiling for A+.

How much will one bad grade affect my GPA?

It depends on how many credits you have completed. Early in your degree a single D in a 3-credit course can drop your GPA significantly; later, the same grade has less impact because it's diluted by more total credits. Use the cumulative GPA section to model the exact effect before grades are finalized.

What GPA do I need to graduate with honors?

Most institutions award Latin honors as follows: Cum Laude typically requires a 3.5 GPA, Magna Cum Laude 3.7, and Summa Cum Laude 3.9 — though exact thresholds vary by school. Check your institution's academic catalog for the official cutoffs.

Can I recover from a low GPA?

Yes, but it takes time. Because GPA is credit-weighted, recovering from a low semester GPA requires several strong semesters to offset it. A student sitting at 2.5 after 60 credits would need to earn a 3.7 across the next 60 credits to reach a 3.1 overall. Use the cumulative section here to map out exactly what's needed.
