Use this calculator for a local semester GPA estimate. Enter one course on each line as course | credits | grade, for example Biology | 4 | A-. The calculator converts common letter grades to grade points, multiplies each point value by the course credits, and divides total points by total included credits. Courses with positive numeric credits are included in the total.
The result is a transparent estimate based on the rows you provide. Your institution may use a different grade scale, plus or minus rules, repeated-course policy, pass or fail treatment, or rounding rule. Check the registrar's policy before using this number for an official transcript decision.
A grade point average is a weighted mean. A three-credit course with 4.0 points contributes 12.0 quality points, while a one-credit course with 4.0 contributes 4.0. The calculator adds all quality points and divides by all included credits, so larger courses have proportionally more influence.
Each row is parsed independently. The course name is displayed in title case, the credit value must be a positive number, and the grade may be a supported letter such as A-, B+, or F or a numeric point value. Invalid credit text or zero and negative credits are skipped.
GPA is the weighted result, Credits is the sum of included positive credits, and each following line shows the parsed points multiplied by course credits. Use those lines to audit a surprising result.
A GPA is meaningful only with its scale and policy. Keep the displayed total credits beside the number when comparing semesters or institutions.
Do not swap the credit and grade fields. The expected order is course | credits | grade.
Do not assume every school maps A- to 3.7 or counts an F identically. Confirm your local catalog.
The tool does not apply repeated-course replacement, withdrawals, pass or fail exclusions, honors weighting, or institution-specific policies.
It does not know whether a row belongs to a semester, cumulative record, or transfer-credit rule. Enter only the courses you intend to summarize.
sum(credits_i × points_i) / sum(credits_i)The denominator is total included credits. A course with twice as many credits contributes twice as much when its grade point is the same.
The built-in map is A+ and A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, D- = 0.7, and F = 0.
An unrecognized grade is parsed as zero points. A nonnumeric, zero, or negative credit value causes that row to be skipped.
The displayed GPA is formatted to two decimal places, while course points are shown to one decimal place.
What is the GPA for A in 3 credits and B in 3 credits?
History | 3 | A Writing | 3 | B
The GPA is 3.50 across 6.0 credits.
Equal credits make the result the average of 4.0 and 3.0.
How does a four-credit A affect a one-credit C?
Lab | 4 | A Seminar | 1 | C
The GPA is 3.60 across 5.0 credits.
The four-credit course has four times the influence of the seminar.
What is the GPA for A-, B+, and B?
Physics | 3 | A- Art | 2 | B+ History | 3 | B
The GPA is 3.34 across 8.0 credits.
The plus and minus distinctions change the point values.
How does F affect a 3-credit A and 3-credit F?
Calculus | 3 | A Chemistry | 3 | F
The GPA is 2.00 across 6.0 credits.
F contributes zero points but its positive credits remain in the denominator.
Can numeric points be entered directly?
Research | 3 | 3.5 Studio | 2 | 2.5
The GPA is 3.10 across 5.0 credits.
Numeric input bypasses the letter map and is used as the point value.
What happens to a course with zero credits?
Project | 0 | A Economics | 3 | B+
The GPA is 3.30 across 3.0 included credits.
Zero and negative credits do not enter the calculation.
Use course | credits | grade, one course per line.
Yes. A through F with plus and minus variants in the documented map are supported.
Yes. A finite numeric grade value is used directly as points.
The credit value may be invalid, zero, or negative. Such rows are excluded.
Yes, when its credits are positive; F contributes zero grade points.
No. It is a local estimate and may differ from your institution's policy.
GPA is credit weighted, so a larger course contributes more quality points and denominator credits.
The GPA is displayed to two decimal places and course point lines to one.
