Reference

Letter grade to 4.0 GPA conversion

This is the scale the calculator uses. The letter-to-point values are the most common in the U.S. The percentage bands vary more from school to school, so treat them as typical, not official.

Letter grade	Typical percentage	GPA points
A+	97–100	4.0
A	93–96	4.0
A-	90–92	3.7
B+	87–89	3.3
B	83–86	3.0
B-	80–82	2.7
C+	77–79	2.3
C	73–76	2.0
C-	70–72	1.7
D+	67–69	1.3
D	63–66	1.0
D-	60–62	0.7
F	Below 60	0.0

Some U.S. schools give an A+ 4.33 instead of 4.0. If yours does, your official GPA can be slightly higher than this estimate.

The formula

How to calculate GPA with credit hours

GPA is a weighted average. Multiply each course's grade points by its credits to get quality points, add them up, then divide by the total credits.

GPA = total quality points ÷ total credits

Course	Grade	Credits	Quality points
Biology	A (4.0)	4	16.0
English	B+ (3.3)	3	9.9
Statistics	B (3.0)	3	9.0
Psychology	A- (3.7)	3	11.1
Total		13	46.0

46.0 ÷ 13 = 3.54. If you averaged the four grades without weighting, you would get 3.50. The 4-credit A pulls the weighted result up.

Cumulative GPA: add the quality points and credits from every term, then divide once. Do not average your term GPAs, because terms with more credits should count more.

How Canadian universities differ

There is no single Canadian GPA scale. Many universities grade in percentages and convert to letters with their own bands, so the same 80% can be worth different GPA points at different schools.

4.0 schools. Universities such as the University of Toronto and McGill report a 4.0 GPA, but each maps percentages to letters with its own bands. Check your transcript key.
Percentage schools. Some universities, including UBC, report averages as percentages rather than a 4.0 GPA.
9-point and other scales. York University uses a 9-point scale. Converting it with a 4.0 table gives the wrong answer.
Applying in Ontario. OMSAS, OLSAS and many Ontario programs convert grades with the OUAC table. Use the OUAC GPA calculator for that, and see the percentage to GPA guide for Canada.

Weighted vs unweighted GPA (U.S.)

In U.S. high schools, a weighted GPA adds extra points for honors, AP or IB courses, so it can go above 4.0. Universities almost always use an unweighted 4.0 scale like the one above, weighted only by credit hours.

Practical guide

How to use the GPA calculator

This calculator estimates a semester GPA on a standard 4.0 scale. It weights each letter grade by the credit value of the course, so a four-credit course affects the result more than a one-credit course. Use the result for planning, not as an official transcript calculation.

Before you begin, check the grading scale published by your school. Some institutions assign different points to plus and minus grades, exclude repeated courses, or calculate program and cumulative averages separately.

Step 1

Add each course

Enter a recognizable course name, select the letter grade, and add its credit hours. Include every course that belongs in the semester you are estimating.

Step 2

Review the weighting

The calculator multiplies each grade value by its credits, adds those quality points, and divides by total attempted credits.

Step 3

Test a scenario

Change a grade or add a planned course to see how the estimated GPA responds. Reset when you want to start a separate semester.

Worked example

Suppose Biology is 4 credits with an A, History is 3 credits with a B+, and Statistics is 3 credits with a B. Their quality points are 16.0, 9.9, and 9.0. Dividing 34.9 by 10 credits gives an estimated GPA of 3.49.

Before you finish

Use attempted credits, not weekly class hours.
Enter the grade shown on your institution’s scale.
Calculate separate terms before combining them for a cumulative estimate.

For planning, keep a copy of the courses and assumptions behind each estimate. If you are considering a future grade, label it as a scenario rather than a result. Academic advisers can explain how your institution treats withdrawals, repeats, transfer credits, and program requirements. The calculator cannot determine academic standing, eligibility, or graduation status.

Common questions

Frequently asked questions

Is a 3.5 GPA good?

On a 4.0 scale, a 3.5 is a B+ to A- average. It meets the minimum for many graduate programs and scholarships, but competitive programs such as medicine and law usually look for higher. What counts as good depends on your school and what you are applying to.

How do I calculate my GPA with credit hours?

Multiply each grade’s points by the course credits, add those quality points, and divide by your total credits. For example, 46.0 quality points over 13 credits is a 3.54 GPA.

How do I convert a percentage to GPA?

Find your school’s letter band for the percentage, then use the letter’s points. Bands differ between schools. For Ontario applications, use the OUAC conversion table instead, which our OUAC GPA calculator applies for you.

How do I calculate a cumulative GPA?

Add the quality points and credits from every term, then divide once. Averaging term GPAs gives the wrong answer when terms have different credit loads.

Is this an official GPA?

No. It is an estimate on a common 4.0 scale. Your registrar’s calculation is the official one, and it may treat repeats, withdrawals and pass/fail courses differently.

What should I enter for pass/fail courses?

Leave them out. Pass/fail and credit/no-credit courses usually carry no grade points, unless your school’s policy says otherwise.
