Academic & Grade Calculators
GPA, grade, and test score calculators for students and educators. Every tool shows the formula and step-by-step math.
These calculators cover the numbers students deal with most: GPA, course grades, final exam scores, and standardized test conversions. Each tool shows the formula used and breaks down the math step by step. Whether you're checking your semester GPA or figuring out what you need on a final, you'll get an answer in seconds.
ACT Score Calculator
Convert raw ACT scores to scaled scores and composite with percentile estimates and college readiness benchmarks.
College GPA Calculator
Calculate semester and cumulative college GPA with credit hours and multi-semester tracking.

Combine multiple semesters into a cumulative GPA and find the semester GPA you need to hit your target.
Final Grade Calculator
Calculate the score you need on your final exam to reach your target course grade.
GPA Calculator
Calculate your semester and cumulative GPA on a 4.0 scale with weighted support for Honors and AP/IB courses.
Grade Calculator
Calculate your weighted course average and find out what grade you need on the final exam.
High School GPA Calculator
Calculate weighted and unweighted high school GPA with Honors, AP, and IB course support.
SAT Score Calculator
Convert raw Digital SAT scores to scaled section and total scores with percentile estimates.
Test Grade Calculator

Which calculator do you need?
To calculate your GPA, use the GPA calculator. It handles both weighted and unweighted scales, including Honors and AP/IB courses. If you need to know what score will save your grade on the last test of the semester, the final grade calculator works backward from your target grade and current average to tell you the exact score you need.
For standardized tests, the SAT score calculator converts raw scores on the Digital SAT to scaled section and total scores with percentile rankings. The ACT score calculator does the same for ACT raw-to-composite conversion, including college readiness benchmarks for each subject.
Common questions about academic calculations
How is GPA calculated on a 4.0 scale?
Each letter grade gets a point value: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. Multiply each grade's point value by the number of credit hours for that course, add them all up, then divide by total credit hours. For example, an A in a 4-credit course and a B in a 3-credit course gives you (4.0 x 4 + 3.0 x 3) / 7 = 3.57 GPA.
What score do I need on the final to pass?
It depends on your current average, the weight of the final, and the minimum grade you're aiming for. The formula is: Required Score = (Target Grade - Current Grade x (1 - Final Weight)) / Final Weight. If you have a 78% average and the final is worth 30% of your grade, you'd need a 74.7% on the final to keep a C+ (77%). The final grade calculator does this math for you instantly.
How do AP and Honors classes affect GPA?
Most schools add extra points to the standard 4.0 scale for advanced courses. AP and IB classes typically add 1.0 point (so an A = 5.0), while Honors classes add 0.5 points (an A = 4.5). This creates a "weighted" GPA that can exceed 4.0, while your unweighted GPA stays on the standard scale. Colleges usually see both numbers, and many recalculate GPA using their own weighting system during admissions review.
