How to use the GPA Calculator

Add each course, credit-hour value, and letter grade to calculate a credit-weighted GPA on a standard 4.0 scale. Optionally combine the new courses with an existing cumulative GPA and credit total.

Translate course letter grades and credit hours into a credit-weighted grade point average. The optional previous-GPA inputs can project a cumulative result, but institutional scales and inclusion rules still control the official transcript calculation.

Fieldlet performs the calculation locally. Compare important academic results with the grading policy published by the relevant instructor or institution.

Each letter grade is converted to grade points on the displayed 4.0 scale.
Grade points are multiplied by course credit hours.
Total quality points are divided by total attempted credit hours; when prior GPA is enabled, its quality points and credits are included first.

Worked examples

Combine courses with different credits

Scenario: A student earns A in a 4-credit course, B in a 3-credit course, and C in a 2-credit course on a 4.0 scale.

Result: The term GPA is 3.22.

Quality points are 16 + 9 + 4 = 29. Dividing 29 by 9 attempted credits gives 3.222…, displayed as 3.22.

See why credits matter

Scenario: An A in a one-credit lab and a C in a four-credit lecture are combined.

Result: The weighted GPA is 2.4, not the simple grade-point average of 3.0.

The lecture contributes eight quality points and the lab contributes four; 12 total points divided by five credits equals 2.4.

How the result is produced

Each course grade is mapped to a grade-point value, multiplied by that course's credits, and added to the other quality points. When a previous GPA is included, Fieldlet first reconstructs its quality points as previous GPA × previous credits, then combines both credit-weighted totals.

Quality points = grade points × course credits
Previous quality points = previous GPA × previous GPA credits
Combined GPA = all quality points ÷ all included credits
Pass/fail, withdrawals, repeats, and plus/minus grades depend on institutional policy

Limitations and common mistakes

The default scale cannot represent every school's plus/minus, honors, repeat, or forgiveness policy.
Official GPA may exclude transfer, pass/fail, developmental, or repeated coursework.

Common questions

Does every school use the same GPA scale?

No. Plus/minus rules, repeated-course policies, weighted classes, and institutional grading scales vary. Use this as an estimator and verify your school's policy.

Does an A+ count as more than 4.0 here?

No. In this default scale, A+ and A both count as 4.0 points.

How do I project a cumulative GPA?

Enable the previous cumulative GPA option, enter the GPA and the number of GPA-bearing credits behind it, then add the new courses you want to model.

Why does my transcript GPA differ?

Your institution may use a different grade-point scale, exclude certain credits, replace repeated grades, or keep more precision during intermediate calculations.
