How do you calculate GPA?

Multiply each course's grade points by its credit hours, add those grade points together, then divide by the total credits.

Does this calculator support plus and minus grades?

Yes. It includes common plus and minus grades such as A-, B+, B-, and C+ using a standard 4.0-style scale.

Is every school GPA scale the same?

No. Schools can use different grade scales, weighting rules, repeated-course policies, and transcript rules. Use this as a planning estimate.

How to calculate GPA

Multiply each course grade point value by the number of credits for that course. Add those grade points together, then divide by the total number of credits. A four-credit class affects GPA more than a one-credit class.

Why credits matter

GPA is usually weighted by credit hours. For example, an A in a one-credit elective helps less than an A in a four-credit core class. This calculator keeps credits visible so the result is easier to explain.

What this GPA estimate does not include

This estimate does not include honors weighting, AP or IB weighting, pass/fail courses, repeated-course replacement, transfer credits, incomplete grades, or school-specific transcript rules.

How students can use the result

Use the result for planning, not panic. Try different grade scenarios before finals, compare how much each class affects the term GPA, and talk with a counselor when official eligibility, scholarships, or graduation requirements depend on GPA.
