GPA Calculator
Calculate term and cumulative GPA on a credit-weighted 4.0 scale.
Calculate a credit-weighted GPA on a 4.0 scale, preview how listed courses affect an existing cumulative GPA, and estimate the average GPA needed over upcoming credits to reach a target.
Term GPA for listed courses
3.444
31 quality points across 9 credits
Projected cumulative GPA after listed courses
3.256
Average GPA needed over next 15 credits for 3.4 cumulative
3.8
This is the credit-weighted average grade-point value needed over the planned credits.
Schools use different GPA scales, letter-grade mappings, repeat policies, transfer-credit rules, pass/fail treatment, and rounding. This tool assumes every entered course uses grade points from 0 to 4.0 and weights them only by credits; verify your institution's official policy.
About This Tool
Calculate grade point average when courses carry different credit values. This GPA calculator multiplies each course's grade points by its credits, totals those quality points, and divides by total credits. It can also combine a new term with an existing cumulative GPA and estimate the average GPA needed over a planned number of future credits to reach a target. The tool deliberately uses numeric grade points rather than guessing how your school maps letter grades, percentages, plus/minus grades, repeats, or transfer work.
How To Use It
- For each course, enter its credit value and the numeric grade points assigned by your institution on a 0–4.0 scale.
- Add or remove course rows as needed. The term GPA is calculated from the listed courses.
- Enter your current cumulative GPA and previously completed credits to preview the cumulative GPA after the listed courses.
- Enter a target cumulative GPA and number of upcoming credits to estimate the average grade-point value needed over those credits.
- Compare the result with your institution's official GPA policy before making academic decisions.
Examples
Credit-weighted term GPA
For 3 credits at 4.0, 4 credits at 3.0, and 2 credits at 3.5, quality points are 12 + 12 + 7 = 31. Across 9 credits, term GPA is 31 ÷ 9 ≈ 3.444.
Project a cumulative GPA
A 3.2 GPA over 30 completed credits represents 96 quality points. Adding 21 quality points from six new credits produces 117 quality points over 36 credits, or a 3.25 cumulative GPA.
Plan toward a target
Starting from a 3.2 GPA over 30 credits, reaching a 3.4 cumulative GPA after 15 more credits requires an average 3.8 GPA across those 15 credits.
Unreachable target under a 4.0 cap
A required future GPA above 4.0 means the target cannot be reached within the stated credits on a standard scale capped at 4.0. The calculator reports that value instead of silently changing the target.
Useful Notes
How GPA is weighted
For each course, quality points equal credits × grade points. Term GPA is total quality points divided by total attempted credits included in the calculation. A four-credit course therefore affects the result twice as much as a two-credit course when both are counted normally.
Cumulative GPA projection
An existing cumulative GPA can be converted back to approximate accumulated quality points by multiplying it by completed credits. The calculator adds the quality points from the listed courses, then divides by the combined credits. If your displayed current GPA was rounded by your institution, the projection can differ slightly from an official calculation that uses unrounded records.
Target GPA planning
To find the future average needed, the calculator solves target GPA × total future credits = existing quality points + future GPA × upcoming credits. Results above 4.0 flag a target that is unreachable on the assumed scale within that number of credits; results at or below zero indicate the target is already maintained under the mathematical model.
Why letter grades are not converted automatically
There is no universal A, A−, B+ or percentage-to-grade-point mapping. Institutions may use 4.0, 4.3, weighted high-school scales, or custom policies. Enter the numeric grade points your own institution assigns so the tool does not pretend one mapping is universal.
Institution rules can change the result
Repeated courses, forgiven grades, transfer credits, withdrawals, pass/fail courses, incomplete grades, extra grade points, and program-specific GPA calculations may be handled differently. This calculator applies a transparent credit-weighted 0–4.0 model only.
FAQ
What is the GPA formula?
Multiply each course's grade-point value by its credits, add all resulting quality points, then divide by the total included credits.
Do all courses count equally?
Not when they have different credit values. A higher-credit course has proportionally more effect on a credit-weighted GPA.
Can I enter A, B+, or percentage grades?
Enter the numeric grade-point value assigned by your institution instead. Letter-grade and percentage mappings vary, so this calculator does not assume a universal conversion.
Why can the required target GPA be above 4.0?
That is the mathematical average required over the planned credits. On a standard scale capped at 4.0, a result above 4.0 means the target cannot be reached within those credits unless your institution permits grade points above 4.0 or applies another policy.
Is projected cumulative GPA exact?
It is exact for the entered credit-weighted model, but an official result can differ because schools may retain more precision than a displayed current GPA or apply special rules for repeats, transfer work, pass/fail courses, and other records.
