How does this handle plus/minus grading and pass/fail courses?

The dropdown includes common 4.0-scale values for plus/minus grades. If your school uses slightly different values, use the closest match as an estimate. For pass/fail or S/U courses that do not affect GPA, set credits to 0 so they are excluded from the calculation.

Can I add more than four classes?

This version supports four course rows at a time. If you have more classes, you can combine similar low-credit courses on one row or run the calculator twice and add total grade points and credits from each run before dividing to find the overall term GPA.

Does this compute cumulative GPA over multiple semesters?

No. It focuses on a single term. To approximate a cumulative GPA, you can add this term’s total grade points and credits to your prior cumulative totals from your transcript, then divide combined grade points by combined credits.

What if my school uses a different GPA scale (for example, 5.0 or 7.0)?

This tool assumes a 4.0 scale. You can still use it conceptually by mapping your grades to equivalent 4.0-style values, but for official numbers and non-4.0 scales you should rely on your institution’s tools or policies.

Is this calculator official for transcripts or honors decisions?

No. It is an unofficial planning aid. Your registrar or official student information system is the source of truth for GPA used on transcripts, class rank, and honors; treat this as a helpful estimate rather than an official record.

College GPA Calculator

Enter course credits and letter grades to compute semester GPA and total grade points.

Results

Calculated GPA: 3.43
Total credits: 9.00
Total grade points: 30.90

Overview

Use this college GPA calculator to quickly estimate your semester grade point average by entering course credits and letter grades. It’s ideal for double-checking where you stand before grades finalize, planning what you need on final exams, or seeing how an upcoming course might shift your average.

How to use this calculator

Enter the credit hours for each course you want included in your GPA for the term.
Choose the corresponding letter grade for each course using the dropdown values on the 4.0 scale.
Review the total credits, total grade points (quality points), and the calculated GPA.
Adjust grades or add a future class scenario to see how different outcomes could raise or lower your semester GPA.

Inputs explained

Course credits: The number of credit hours for each class, such as 3 for a standard lecture course or 1 for a lab or seminar. If you set credits to 0, that course will not be counted in the GPA.
Course grade: The letter grade you expect or received, mapped to a numeric value on a 4.0 scale (A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, and so on). Choose the option that matches your school’s grading scheme most closely.

Outputs explained

Calculated GPA: Your term GPA on a 4.0 scale based on the credits and grades you entered. This is the main number schools use for semester GPA on transcripts and progress reports.
Total credits: The sum of all credit hours included in the calculation. This should match the total number of graded credits for the term, excluding any pass/fail or audited classes you intentionally left out.
Total grade points: Also called quality points—this is the sum of Credits × Grade value across your courses. It is the numerator in the GPA formula before dividing by total credits.

How it works

Most schools on a 4.0 scale convert letter grades into numeric grade points (for example, A = 4.0, A− = 3.7, B+ = 3.3, and so on).

For each course, we multiply the credit hours by the numeric grade value to get quality points: Quality points = Credits × Grade value.

We add quality points across all included courses and divide by the total number of credits: GPA = Total quality points ÷ Total credits.

Any row with 0 credits is ignored in the calculation, so you can leave lines at zero if you are taking fewer than four classes or want to exclude a pass/fail course.

Formula

Grade points for each course = Credits × Grade value\nTotal grade points = Σ(Credits × Grade value) across all courses\nTotal credits = Σ(Credits) across all included courses\nGPA = Total grade points ÷ Total credits

When to use it

Estimating your semester GPA before your school posts the official number, using expected grades from each course.
Testing how different final exam outcomes or project grades could affect your term GPA (for example, checking the impact of getting a B vs. an A in a single class).
Checking whether your projected GPA meets scholarship, honor roll, athletic eligibility, or program major requirements.
Planning course loads by seeing how a heavier or lighter credit schedule could affect your GPA target.
Explaining GPA math to parents or younger students who are new to credit-weighted grading systems.

Tips & cautions

If a pass/fail or S/U course does not affect GPA at your school, set its credits to 0 so it is excluded from the calculation.
If your institution uses a slightly different numeric scale for plus/minus grades, choose the closest available values here or manually adjust expectations up or down.
You can combine multiple low-credit seminars or labs into one row by summing their credits and using a weighted average grade if they all share the same or similar grades.
Remember that this tool focuses on a single semester. For cumulative GPA, you will need prior total credits and total grade points to combine with this term’s results.
Double-check your school’s grading policies for repeated courses, withdrawals, or incompletes—those may be handled differently than standard letter grades.
Supports up to four courses per run; if you take more, you may need to combine similar classes on one row or run multiple passes and combine totals manually.
Assumes a standard 4.0 scale with the provided plus/minus mapping; it does not support custom scales or weightings (such as honors/AP weighting) out of the box.
Calculates term GPA only; cumulative GPA across multiple semesters requires adding prior total grade points and credits from your transcript.
Does not account for school-specific rules such as grade forgiveness, repeated course policies, or separate weighting for graduate versus undergraduate courses.

Worked examples

Three 3-credit classes: A, B+, and B

Credits: 3, 3, 3 with grade values 4.0 (A), 3.3 (B+), and 3.0 (B).
Total grade points = (3 × 4.0) + (3 × 3.3) + (3 × 3.0) = 12 + 9.9 + 9 = 30.9.
Total credits = 3 + 3 + 3 = 9.
GPA = 30.9 ÷ 9 ≈ 3.43 for the term.

Adding a 1-credit lab with an A−

Original three 3-credit classes from the prior example plus a 1-credit lab with grade value 3.7 (A−).
Additional grade points for the lab = 1 × 3.7 = 3.7.
New total grade points = 30.9 + 3.7 = 34.6; new total credits = 9 + 1 = 10.
Updated GPA = 34.6 ÷ 10 = 3.46. You can see how even a 1-credit course nudges the term GPA.

Excluding a pass/fail course

Suppose you have three graded 3-credit classes and one 2-credit pass/fail course that does not affect GPA.
Enter the three graded classes with their real credits and grades. For the pass/fail course, set credits to 0 so it is ignored.
The calculator totals only the graded credits and grade points, mirroring how many schools handle non-graded courses.

Deep dive

This GPA calculator multiplies course credits by 4.0-scale grade points, sums total quality points, and divides by total credits to show your semester GPA. Enter credits and letter grades for up to four courses to see total credits, total grade points, and the resulting GPA in one place.

Use it to estimate how different grades will impact your term GPA, check whether you’re tracking toward scholarship or major requirements, or sanity-check the GPA your school reports at the end of the semester.

Because the calculator uses a standard 4.0 scale with common plus/minus options, it works for most colleges and universities; just confirm any small differences with your official grading policy.
