Calculator use

Best for

  • Use this GPA calculator to estimate semester GPA from up to four classes, credit hours, and letter-grade point values.
  • Checking calendar, work-hour, school, deadline, age, or duration math before copying the result elsewhere.
  • Comparing inclusive versus exclusive dates, breaks, grading weights, or time spans with the assumptions visible.
  • Doing a quick schedule or school planning check without opening a spreadsheet.

Before relying on it

Check first

  • Mixing inclusive and exclusive date counting, time zones, overnight shifts, unpaid breaks, holidays, or school-specific grading rules.
  • Rounding time or grades too early and then using the rounded result in another calculation.
  • Treating a planning result as payroll, HR, transcript, legal deadline, or official school policy.

Details

What to know before using the result

Quality pointsGrade points x credits

Each class contributes its grade-point value multiplied by its credit hours, so higher-credit classes move GPA more.

Scale choice4.0 by default

Use the grade-point values from your school. Honors, AP, weighted, pass/fail, and repeat rules can use different treatment.

Semester estimateNot transcript official

This calculator estimates the entered term only. Official cumulative GPA depends on your institution's transcript and repeat policies.

FAQ

Common questions

How do I calculate GPA?

Multiply each class grade point by credits, add quality points, then divide by total credits.

Does this support weighted GPA?

It uses the grade point values you choose. Weighted systems can be approximated by entering the weighted point value if available.

What if I have more than four classes?

Use the same formula for additional classes or combine classes with the same grade point value.
