GPA calculator

Credit-weighted GPA on a 4.0 or 4.3 scale or from percentages, cumulative GPA with previous credits, the grade you need for a target, and UK degree classes.

Inputs

Universities differ: check your registrar’s scale and pick the closest match.

Courses: name, credits and grade (letter such as B+ or a percentage)

On the UK scale, your previous average mark in %.

Your GPA

Add each course with its credits (credit hours or units) and your grade, and the calculator returns your credit-weighted grade point average: GPA = the sum of grade points × credits, divided by the total credits. With A− (3.7) in a 4-credit course, B+ (3.3) in a 3-credit course, B (3.0) in a 4-credit course and A (4.0) in a 3-credit course, the quality points are 14.8 + 9.9 + 12 + 12 = 48.7 over 14 credits, a GPA of 3.48.

Grades can be letters or percentages. On the US 4.0 scale A and A+ are both 4.0, A− 3.7, B+ 3.3, B 3.0, B− 2.7 and so on down to F = 0; the 4.3 option gives A+ 4.3, as some universities do. Percentages are converted with the common US table (93–100 = A, 90–92 = A−, 87–89 = B+ … under 65 = F). These scales are widely used but not universal: many universities publish their own, some have no minus grades, and cut-offs vary. Pick the option that matches your transcript, and treat the result as a check, not an official figure.

Enter your previous cumulative GPA and completed credits to get your new cumulative GPA, or switch to target mode to see the average you need on the credits you still have to take: needed = (target × all credits − quality points so far) ÷ remaining credits. For UK degrees, choose the UK option and enter module marks in %: the calculator gives the credit-weighted average and the usual class boundaries (70% First, 60% 2:1, 50% 2:2, 40% Third). Year weightings and borderline rules differ by university.

How to use it

  1. Choose the grading scale your university uses.
  2. Enter each course’s name, credits and grade (a letter like B+ or a percentage like 87). Add or remove rows as needed.
  3. Optionally enter your previous cumulative GPA and completed credits to see your cumulative GPA.
  4. To plan ahead, switch the mode to target, enter the GPA you want and the credits you still have to take, and read the average you need.

Frequently asked questions

How do I calculate my GPA by hand?

Multiply each course’s grade points by its credits to get quality points, add them up and divide by the total credits. A (4.0) in a 3-credit course and B (3.0) in a 4-credit course give (12 + 12) ÷ 7 = 3.43, not the simple average of 3.5, because the 4-credit course counts more.

Is an A+ worth 4.0 or 4.3?

It depends on the university. Most US colleges cap the scale at 4.0, so A+ and A are both 4.0; some, including a number of Canadian and US institutions, give A+ 4.3. Use the 4.3 option only if your transcript does.

How is cumulative GPA calculated?

Cumulative GPA = (previous GPA × previous credits + this term’s quality points) ÷ (previous credits + this term’s credits). With a 3.2 GPA over 60 credits and a 3.48 term over 14 credits, the new cumulative GPA is (192 + 48.7) ÷ 74 = 3.25.

What average do I need to raise my GPA?

Use target mode. With 74 credits at 3.25 and 30 credits to go, reaching a 3.4 cumulative GPA needs (3.4 × 104 − 240.7) ÷ 30 = 3.76 on average, roughly an A−. If the answer is above the scale maximum the target cannot be reached with those credits.

How are UK degree classifications worked out?

Usually on a credit-weighted average of the modules that count: 70% or more is a First, 60–69% an Upper Second (2:1), 50–59% a Lower Second (2:2) and 40–49% a Third. Most universities weight the final year more than the second, ignore the first year and consider students just below a boundary. Enter only the modules that count and check your regulations.

Do pass/fail courses count?

Usually not: pass/fail, audited and transfer courses often carry credits but no grade points. Leave them out unless your university says otherwise. Repeated courses are handled differently by each institution; some replace the first grade, some average both.
