What Is a GPA Calculator?

A GPA calculator converts your letter grades into quality points, weights them by credit hours, and divides by total credits attempted — giving you the same number that appears on your official transcript without waiting for grades to post.

This tool supports both the standard unweighted 4.0 scale used by most colleges and the weighted 5.0 scale used by many high schools for Honors and AP courses. It also lets you layer in your prior cumulative GPA to project how your current semester will move your overall average.

How to Calculate Your GPA

1
Choose your GPA scale. Select Unweighted (4.0) for standard grading or Weighted (5.0) if your school awards bonus points for Honors, AP, or IB courses.
2
Enter your courses. Add each course, select your letter grade from the dropdown, and enter the credit hours. Add as many rows as needed for the semester.
3
Add prior cumulative data (optional). Enter your existing cumulative GPA and total credits if you want to see how this semester will affect your overall transcript.
4
Read your results. The calculator instantly shows your semester GPA and your projected cumulative GPA including your prior credits.

Who Is This For?

  • →Students checking their GPA before applying to grad school or scholarships — know your number before you submit an application, not after.
  • →International students converting letter grades to the 4.0 scale — verify how your home country grading maps to the US standard before applying to US institutions.
  • →Students on academic probation tracking what grades they need to recover — use the cumulative GPA field to reverse-engineer the minimum semester average needed to return to good standing.

Key Benefits

  • ✓Runs in your browser. Your grades never leave your device — nothing is stored or transmitted.
  • ✓Completely free. No subscription, no paywall, no account required.
  • ✓No account needed. Works instantly — open the page and start calculating.
  • ✓Supports both weighted and unweighted scales. Switch between 4.0 and 5.0 systems with one toggle — essential for high school students with AP or Honors courses who need to see both figures.

Common Use Cases

Grad school application prep. Most programs list a minimum GPA cutoff. Run your current GPA and then model what grades this semester would produce to see if you'll hit the threshold before you apply.

Scholarship eligibility checks. Many scholarships require a minimum 3.0 or 3.5 GPA to renew. Track your semester-by-semester GPA to stay on top of eligibility requirements without surprises at renewal time.

Academic recovery planning. If you're on probation, use the cumulative GPA field to calculate exactly what semester average you need this term to bring your overall GPA back above 2.0.

High school college applications. Use the weighted scale to see your GPA the way your high school reports it, and the unweighted scale to see how colleges may recalculate it when comparing applicants.

Unweighted GPA (4.0 Scale)

An Unweighted GPA is the traditional university standard. In this system, all classes are treated equally regardless of their difficulty level.

An "A" grade in standard physical education is worth exactly the same 4.0 points as an "A" in organic chemistry. This scale maxes out at a hard ceiling of 4.0. College admissions officers frequently recalculate applicants' transcripts back to an unweighted standard to level the playing field across different high school districts.

Weighted GPA (5.0 Scale)

A Weighted GPA system was created to reward students who challenge themselves with tougher curriculums.

When the "Weighted" toggle is activated in our calculator, it mimics standard high school bonus scaling. Completing an Honors tier class grants a +0.5 quality point boost (an 'A' is worth 4.5). Completing a collegiate tier course, such as Advanced Placement (AP) or International Baccalaureate (IB), grants a +1.0 boost, meaning an A generates 5.0 points.

Frequently Asked Questions

What is a GPA? ↓
GPA stands for Grade Point Average — the standard numerical measure of academic performance used by high schools, colleges, and graduate programs worldwide. It is calculated by dividing the total quality points earned (grade × credit hours) by the total credit hours attempted, producing a number on a 4.0 or 5.0 scale.
Is this GPA calculator free? ↓
Yes, completely free. It runs entirely in your browser — no account required, no data stored, and no subscription needed. Your grades never leave your device.
What is a good GPA? ↓
A 3.5 or above is generally considered excellent. A 3.0 is the floor for most graduate school applications. A 2.0 is typically the minimum required to maintain financial aid eligibility. For context, Ivy League schools report median GPAs of 3.9 or higher, while most state universities accept students with GPAs of 3.0 and up.
How is GPA calculated? ↓
GPA is calculated by multiplying each course's grade point value by the number of credit hours, summing those products (called quality points), and dividing by the total credit hours attempted. For example, a 4.0 in a 3-credit course contributes 12 quality points; a 3.0 in the same course contributes 9. Divide total quality points by total credit hours for your GPA.
What GPA do I need for graduate school? ↓
Requirements vary widely. Most graduate programs require a minimum of 3.0. Competitive programs in business, law, and STEM typically expect 3.5 or higher. Medical and law schools are the most selective — top programs report median GPAs of 3.7 to 3.9. Always check each program's specific requirements, as GPA is evaluated alongside test scores, recommendations, and experience.
How are Pass/Fail classes factored in? ↓
Pass/Fail classes do not impact your GPA. Passing grants credit hours toward graduation, but because no letter grade is assigned, zero quality points are added to the formula. A failing grade in a Pass/Fail course may still count as zero quality points at some institutions — check your school's specific policy.
Does withdrawing from a class hurt my GPA? ↓
A W (Withdrawal) does not affect your GPA mathematically — it contributes zero quality points and zero credit hours to the calculation. However, multiple withdrawals can raise concerns for graduate admissions committees, as they may indicate difficulty completing coursework. Withdraw strategically, not as a routine substitute for course management.
