GPA Calculator — Calculate GPA from Letter Grades & Find Your Target GPA
Free GPA calculator on a 4.0 scale. Convert letter grades to GPA with credit weighting, see your letter equivalent and academic standing, and use the target GPA calculator to find out what GPA you need in your remaining credits.
Skycally's GPA Calculator turns a list of courses into a weighted grade point average on the standard American 4.0 scale. Add one row per class, choose the letter grade from A+ down to F, enter the credit hours, and the result recalculates as you type. Because the average is credit-weighted, a four-credit course counts more than a one-credit elective — which is exactly how registrars compute a cumulative GPA and why simply averaging letter grades gives the wrong number.
The grade points used are the ones almost every US college publishes: A and A+ are 4.0, A- is 3.7, B+ is 3.3, B is 3.0, B- is 2.7, and so on down in 0.3 and 0.4 steps to D- at 0.7 and F at 0.0. Multiply each course's grade points by its credits, add those products together, and divide by the total credits attempted. Three three-credit courses graded A, B+ and B- give (4.0×3 + 3.3×3 + 2.7×3) ÷ 9 = 3.33.
The Target GPA tab answers the question students actually search for: what GPA do I need to get to a 3.5? Enter your current cumulative GPA, the credits behind you, the GPA you want and the credits still ahead, and the tool solves for the average you must earn in those remaining credits. When that number lands above 4.0 the calculator says plainly that the target is not achievable with the credits left, and when your current GPA is already above the target it tells you that you are on track.
Everything runs locally in your browser with plain arithmetic — nothing you type is uploaded, stored or logged, and there is no signup. Numbers are formatted in US English so results look identical on every device. If your school uses a weighted scale with extra points for honors or AP classes, add the bonus to the grade points yourself; this calculator uses the unweighted 4.0 scale that most colleges report on a transcript.
Frequently Asked Questions
How do I calculate my GPA?
Multiply each course's grade points by its credit hours, add all those products, then divide by the total credits. For example (4.0×3 + 3.3×3 + 2.7×3) ÷ 9 = 3.33. The Calculate GPA tab does this automatically as you type.
What GPA is an A?
An A is 4.0 on the standard unweighted scale, and A+ is also counted as 4.0 at most US colleges. An A- is 3.7. Straight A grades in every course give a perfect 4.00 GPA.
What GPA do I need to get a 3.5?
Use the formula required = (target × total credits − current GPA × completed credits) ÷ remaining credits. With a 3.0 over 60 credits and 30 credits left, reaching a 3.5 needs (3.5×90 − 3.0×60) ÷ 30 = 4.5 — impossible, which is why the tool flags it as not achievable.
Is a 3.0 GPA good?
A 3.0 is a solid B average and meets the minimum requirement for most graduate programs, scholarships and internships. This calculator labels 3.0-3.69 as Good Standing, 3.7 and above as Dean's List territory, and below 2.0 as academic probation risk.
How many credits do I need to raise my GPA?
It depends on the gap. The more credits you have already completed, the more new credits it takes to move the average. Increase the credits remaining in the Target GPA tab until the required GPA drops to 4.0 or below to see the minimum workload that makes your goal possible.
How do I convert a letter grade to GPA?
Use the standard mapping: 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, F = 0.0. Each grade is shown with its points inside the grade dropdown.
Does this calculator handle weighted or AP GPA?
It uses the unweighted 4.0 scale that colleges report on a transcript. If your high school adds a point for honors or AP courses, calculate that bonus separately — the credit weighting here still applies to any scale you feed it.
Is this college GPA calculator free and private?
Yes. It is completely free with no signup, and every calculation runs in your browser. Nothing you enter is sent to a server, stored or logged.
