Overview
A credit-weighted GPA calculator on the 4.0 scale. You list courses with their credit hours and letter grades, and it computes total credits, total grade points, and the resulting GPA. It also shows an approximate percentage equivalent, clearly labelled as an approximation, using a common linear conversion.
How It Works
Each row has a course name, a credit field (0 to 12, in 0.5 steps), and a grade dropdown covering A+ through F. Start from the two sample rows, edit or delete them, and click Add course for as many rows as you need. The three tiles at the bottom update live: total credits, total grade points, and your GPA on the 4.0 scale. Underneath, an approximate percentage figure appears once the GPA is above zero.
Step-by-Step Usage Guide
- Replace the sample courses with your real course names.
- Enter each course's credit hours.
- Select the letter grade you received or expect.
- Read the GPA tile and, if useful, the approximate percentage underneath.
Technical Specifications & Standards
The grade table follows the common plus/minus 4.0 convention: A+ and A both earn 4.0, A− 3.7, B+ 3.3, B 3.0, B− 2.7, C+ 2.3, C 2.0, C− 1.7, D 1.0, and F 0.0. The GPA is the credit-weighted mean — each grade's points are multiplied by that course's credits, summed, and divided by total credits — which is why a 4-credit A outranks a 3-credit A in the average. Note that treating A+ and A identically is one specific convention; some universities award A+ above 4.0 or exclude it from the average, so check your institution's chart. The percentage line converts by GPA/4 × 100 capped at 100, a rough linear mapping that many admissions pages publish but that no institution uses officially — that is why the tool labels it approximate rather than a conversion. Nothing is stored: courses live in component state and vanish on refresh, so note your result before leaving the page.
Targeted Use Cases
- Checking whether this semester's expected grades keep you above a scholarship threshold.
- Comparing a heavy-credit science course's pull on your average versus an elective.
- Planning which grade you need in a remaining course to hit a target GPA.
- Translating a plus/minus transcript into a single 4.0-scale number for an application form.
Notes & Gotchas
- Enter credit hours exactly as your transcript shows; weighting is where most hand calculations go wrong.
- Use your institution's own grade-point table if it differs from the standard A+/A = 4.0 chart here.
- Treat the percentage figure as a rough equivalent only, never as an official conversion.
- Leave pass/fail courses out unless your school assigns them grade points, which most do not.
Frequently Asked Questions
What grade points does each letter earn?
A+ and A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, C− = 1.7, D = 1.0, and F = 0.0. The GPA is the credit-weighted average of those points.
How is the percentage equivalent calculated?
By a simple linear mapping of GPA/4 × 100, capped at 100. It is shown as an approximation because institutions use many different, non-equivalent conversion charts; it is not an official conversion.
Does the calculator save my courses?
No. Courses and grades are held in React state only. Refreshing the page or navigating away resets the list to the two sample rows, so note your GPA before you leave.
Can I use this for a 10-point or ECTS scale?
Not directly. The grade table and the 4.0 denominator are fixed. For other scales, convert each grade to its 4.0-scale equivalent first, or use your institution's own calculator for the official number.
