What GPA do I need next term?

Work out your GPA for a semester, or your cumulative GPA across all your semesters. Choose a letter grade and the credits for each course and the calculator shows your GPA as you go. It handles Honors, AP and IB boosts for a weighted GPA, ignores pass/fail courses, and can tell you the GPA you need next term to reach a goal.

How to calculate your GPA

  1. Pick the letter grade for each course and enter its credits or hours. In most high schools every class is 1 credit; in college most courses are 3 or 4.
  2. Set the class type to Honors, AP, IB or college if your school gives those classes extra points. The calculator then shows both your unweighted and weighted GPA.
  3. To get your cumulative GPA, open “Add your previous GPA” and enter your GPA so far and the credits it covers.
  4. Use “What GPA do I need next term?” to plan for a scholarship, honors list or program cut-off.

How GPA is calculated

Each letter grade has a number of grade points (A = 4.0, B = 3.0, and so on). Multiply the points by the course credits, add them up, and divide by the total credits:

GPA = (points₁ × credits₁ + points₂ × credits₂ + …) ÷ total credits

Example

English A (4 credits), Math B+ (3 credits), Biology B (4 credits), Spanish A- (3 credits). That is (4.0 × 4 + 3.3 × 3 + 3.0 × 4 + 3.7 × 3) ÷ 14 = 49 ÷ 14 = 3.50.

Weighted vs unweighted GPA

An unweighted GPA uses the same 4.0 scale for every class. A weighted GPA gives extra points for harder classes, so an A in an AP class can count as 5.0. This calculator adds 0.5 for Honors and 1.0 for AP, IB and college or dual-enrollment classes, which is the most common system. An F never gets a boost. Colleges often recalculate GPA their own way, so it is worth knowing both numbers.

Cumulative GPA

Your cumulative GPA is not the average of your semester GPAs. It is weighted by credits: (previous GPA × previous credits + this term’s grade points) ÷ all credits. A 3.0 over 60 credits plus a 4.0 over 15 credits gives (180 + 60) ÷ 75 = 3.20, not 3.5.

GPA scale

A+97–1004.0 (4.3 on some scales)
A93–964.0
A-90–923.7
B+87–893.3
B83–863.0
B-80–822.7
C+77–792.3
C73–762.0
C-70–721.7
D+67–691.3
D63–661.0
D-60–620.7
FBelow 600.0

This is the most common US scale. Your school may draw the lines a little differently, for example A from 90% instead of 93%, so check your syllabus or student handbook if a grade sits right on a boundary.

Pass/fail (P/NP) courses give you credits towards graduation but do not count in your GPA, so the calculator leaves them out.

Frequently asked questions

Is a 3.5 GPA good?

Yes. A 3.5 is roughly an A-/B+ average and is above the typical US college average of about 3.1. Competitive programs and scholarships often look for 3.5 or higher.

What is the difference between the 4.0 and 4.3 scale?

The only difference is the A+. On a 4.0 scale it is worth 4.0, the same as an A. On a 4.3 scale it is worth 4.3. Choose the scale your school uses at the top of the calculator.

How do I convert a percentage to GPA?

Find your percentage in the scale table above. For example 88% is a B+, which is 3.3 grade points. To get the letter for a whole class from your scores, use the grade calculator.

How can I raise my GPA quickly?

Courses with more credits move your GPA the most, and early semesters move it more than later ones because fewer credits are behind them. The “What GPA do I need next term?” box shows whether your target is realistic.

Does this work for Indian CGPA?

Indian universities usually use a 10-point CGPA, which works differently. This calculator follows the US 4.0 system.
