GPA Calculator

Multiply each grade's points by its course credits, add those quality points, and divide by total credits. The form uses its displayed US 4.0 plus/minus scale.

An A worth 4.0 in a 3-credit course and a B worth 3.0 in a 1-credit course gives (4×3 + 3×1)/4 = 3.75, not the unweighted 3.5.

Match the grade scale to your school before using the estimate. Enter all relevant credits to avoid an artificially high or low average.

School policies for repeated courses, pass/fail, honors weighting and transfer credits differ. This estimate does not replace an official transcript.

Choose a grade for each course and enter the credits assigned to it. Credits determine how much that course contributes to the average. A four-credit course carries twice the weight of a two-credit course with the same grade. The calculation does not simply average letter-grade values across rows. Enter the course credits from your institution's records rather than assuming that every class has the same weight because it meets for a similar number of hours.

The displayed scale assigns A and A+ four points, then uses the shown plus/minus values for the other grades. Your institution may use a different scale, particularly for an A+, honors courses or special grading arrangements. The form does not let you define an entirely different scale. Confirm that the available values match the calculation you need before interpreting the result as an estimate of your official GPA.

An A in a three-credit course contributes 12 quality points. A B in another three-credit course contributes nine. Together, 21 points divided by six credits gives a GPA of 3.50. If the B course has only one credit instead, the result is 15 points divided by four credits, or 3.75. The letters have not changed; only their relative weight has. This explains why averaging the two letter values without credits can be wrong.

An F contributes zero quality points but still counts its entered credits in the denominator. Add a two-credit F to the three-credit A and one-credit B example, and 15 points divided by six credits gives 2.50. Leaving the failed course out would make the estimate artificially higher if your institution includes it. Whether a particular course belongs in an official GPA calculation is a policy question, not something the letter menu decides for you.

A semester GPA and a cumulative GPA use the same weighted idea but can include different sets of courses. Entering only this semester's classes does not automatically produce a cumulative result. The form has no separate starting cumulative-GPA field, so it cannot combine a previous average and credit total as though they were a normal letter-graded course. To model a broader group, use the relevant graded courses and their credits under the appropriate institutional rules.

Pass/fail, withdrawals, transfer work and repeated courses may receive special treatment. Do not select F simply because the form has no pass/fail option; those are not necessarily equivalent. If a repeated grade replaces an earlier attempt at your institution, decide which record belongs in the estimate according to that policy. Rows with non-positive or invalid credits do not contribute here. Review the included course list instead of assuming every visible row has been counted.

The numerical result is an estimate under this grade scale and the credits entered. Any honors wording appearing with it is a generic display label, not confirmation that a school will award that distinction. Institutions can have their own thresholds, credit requirements and other conditions. The calculator does not inspect a transcript or evaluate scholarship, graduation or academic-standing rules. For those decisions, the official policy and recorded GPA take priority.

A rounded display also deserves care near a cutoff. The underlying weighted average can have more decimal places than the two shown on screen, and an institution may apply its own rounding or truncation rule. Keep the course inputs if you need to inspect the arithmetic. Use the tool to understand the effect of grades and credits, then confirm the scale, included courses and applicable policy before relying on it for an important academic decision.
