What is the 4.0 GPA scale?

The 4.0 scale assigns A/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+ = 1.3, D = 1.0, D- = 0.7, and F = 0.0.

What is the difference between weighted and unweighted GPA?

A weighted GPA accounts for credit hours — a 4-credit A matters more than a 1-credit A. An unweighted GPA treats all courses equally. This calculator computes weighted GPA, which is the standard used by most colleges.

What Is a GPA Calculator?

A GPA (Grade Point Average) calculator is a tool that converts letter grades into numerical values on a standardized scale — typically the 4.0 scale used by most American colleges and universities — and computes a weighted average based on each course’s credit hours. Your GPA is one of the most important academic metrics: it determines eligibility for the Dean’s List, academic probation thresholds, scholarship qualifications, graduate school admissions, and even some job applications. Manually calculating GPA across dozens of courses and multiple semesters is tedious and error-prone, which is why a calculator is invaluable.

TweakFiles GPA Calculator runs entirely in your browser — no data is sent to any server, no account is required, and there are no usage limits. Simply enter your courses, select grades, specify credit hours, and get your weighted GPA instantly. Unlike many online GPA calculators that require registration or limit free usage, TweakFiles is 100% free with no restrictions.

How the 4.0 Scale Works

The 4.0 grading scale assigns numerical values to letter grades: A and A+ receive 4.0 points, A- receives 3.7, B+ gets 3.3, B gets 3.0, and so on down to F at 0.0 points. To calculate your GPA, each grade’s point value is multiplied by the number of credit hours for that course, producing "quality points." All quality points are summed and divided by total credit hours to yield your weighted GPA. This weighting ensures that a 4-credit A counts more toward your GPA than a 1-credit A, accurately reflecting your academic performance.

Why Credit-Weighted GPA Matters

Credit-weighted GPA is the standard used by virtually all accredited institutions because it accounts for the relative importance of each course. A student taking 4-credit core courses and 1-credit electives needs a system that reflects the heavier investment in core courses. Graduate programs, law schools, medical schools, and employers all expect weighted GPA on transcripts and applications. This calculator uses the credit-weighted formula exclusively, matching what your registrar reports.

How to Calculate Your GPA in 3 Steps

Enter Your Courses

Type each course name (optional but helpful for tracking), select the letter grade you received from the dropdown, and enter the number of credit hours. The calculator starts with 4 rows, but you can add as many courses as needed. Include courses from all semesters to calculate your cumulative GPA, or enter only the current semester for a term GPA.

Click Calculate

Press the "Calculate GPA" button to compute your weighted grade point average. The calculator multiplies each grade’s point value by the credit hours, sums all quality points, and divides by total credits. Results appear instantly with no server processing or wait time.

Review Your Results

See your overall GPA prominently displayed, along with total credit hours and total quality points. A per-course breakdown shows exactly how each course contributed to your GPA, making it easy to identify which courses are pulling your average up or down. Use this information to plan future course selections strategically.

Frequently Asked Questions

GPA is calculated by multiplying each course grade’s quality points by its credit hours, summing all quality points, and dividing by total credit hours. For example, an A (4.0) in a 3-credit course yields 12.0 quality points. If you have three courses totaling 9 credits with 30 quality points, your GPA is 30 / 9 = 3.33.

The 4.0 scale is the most common grading system used in the United States. It assigns A/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+ = 1.3, D = 1.0, D- = 0.7, and F = 0.0. Some institutions use variations (like 4.3 for A+), but the standard 4.0 scale is used by most colleges and universities.

A weighted GPA accounts for credit hours — a 4-credit A contributes more than a 1-credit A. An unweighted GPA treats every course equally regardless of credit hours. This calculator computes weighted GPA, which is the standard used by most colleges and universities for admissions and academic standing.

Yes. Simply add all courses from every semester into the table. The calculator computes a single weighted GPA across all entries, giving you your cumulative GPA. You can add as many courses as needed using the Add Course button.

This calculator uses the standard US 4.0 scale used by most colleges and universities. If your institution uses a different scale (such as a 5.0 scale for AP/honors courses, or a 10-point scale), the results may not match. Check with your registrar for your school’s specific grading policy.
