Predicting your semester GPA is powerful: it helps you decide whether to drop a course, change your study plan, or aim for a specific scholarship threshold. This guide walks through an easy method to forecast your GPA and shows how to use our GPA Trend & Forecast tool to test scenarios.
Gather course grades and credits
List all the courses for the semester with their credit hours and your current or expected grades. Use numeric percentages or letter grades — our calculator accepts both. Be realistic with expectations: use a conservative estimate if you’re uncertain.
Calculate grade points
Convert each course grade to grade points (A=4.0, B+=3.3, etc.). Multiply the points by the credit hours for each course to get total grade points. Sum the totals and divide by total credits to get the projected GPA.
Test scenarios
Want to know what happens if you get a B+ in one class and an A in another? Or if you retake a class next semester? Use scenario testing: change the grade values for one or two courses and recalculate. This helps you prioritize your study time effectively.
Use our GPA Trend & Forecast tool
Our GPA Trend & Forecast tool lets you add course credits and expected grades, then instantly shows the projected GPA. It’s the fastest way to answer “What if I get an A in this class?” without doing the math by hand.
Final advice
- Be mindful of credit-heavy courses — they have a bigger influence on GPA.
- Small improvements in high-credit classes often raise your GPA more than perfecting low-credit electives.
- Use projections to set realistic goals and plan study time where it matters most.
