Weighted to Unweighted GPA Converter

An unweighted GPA is the credit-weighted mean of grade points under a particular grade scale. This calculator uses the displayed plus/minus mapping, where A and A+ are 4.0, A- is 3.7 and B+ is 3.3. Your school may use a different mapping or exclude some courses. Enter each eligible course and its credits from the transcript rather than trying to subtract a fixed number from an overall weighted GPA. The overall weighted number alone cannot reveal the original course mix.

The optional weights here add 0.5 for Honors and 1.0 for AP, IB or dual-enrollment selections when the grade is not failing. Those are this calculator’s assumptions, not universal school rules. Colleges can define their own eligible subjects, year ranges and weighting caps. University of California GPA instructions, for example, need to be followed in their own context. A general calculator cannot predict admission or assign reliable college cutoffs. Use the result to check arithmetic and understand scenarios, then consult the actual application instructions.

The weighted summary alone does not identify which courses received bonuses, so an exact unweighted result cannot be recovered by subtracting a fixed number. Enter each grade, level and credit value. The calculator weights the quality points by credits rather than treating a half-credit course as a full-credit course. Zero-credit entries are excluded; invalid or absent credits do not silently become one credit. This example policy awards a half-point Honors bonus or one AP/IB point for passing grades. Failing grades receive no bonus. Your school may use another policy, so compare its transcript instructions with these assumptions. When no included credits remain, the zero display means no calculable average, not an official academic record. Use the displayed plus/minus values consistently and avoid entering both semester and annual grades unless your school's method counts both.

The results do not predict admission or establish a qualifying score for ranked universities. A college's minimum eligibility requirement, admitted-student range and enrolled-student average are different statistics, and they may use different GPA scales. Check the current institution's official instructions before making a comparison. This is not a UC capped GPA calculator. UC uses its own eligible course period, course definitions and honors-point cap. Use the linked UC instructions and your school counselor for that calculation. If an application asks for the GPA and scale shown on your transcript, report those values instead of replacing them with this estimate. For example, two equal-credit A courses, one regular and one AP, produce 4.0 unweighted and 4.5 weighted under this tool's model; that illustration is arithmetic, not a promise of college eligibility. Keep your course list for review and use the estimate for planning.

Check the total credits against the transcript list, then manually calculate a small two-course sample to confirm the mapping. A unexpectedly large change usually warrants checking the course credit value or level. Course names help you identify rows but are not required personal identifiers; do not enter a student ID when it adds nothing to the calculation. The browser calculates locally. A screenshot you later share is a separate disclosure, and the calculator does not certify school records. Consult your counselor when repeat courses, pass/fail grades or transfer rules make the transcript more complex than this model.

Suppose one eligible course earns an A for one credit and another earns a B for two credits. Under this scale, the quality points are four times one plus three times two, totaling ten. Divide by three total credits to obtain an unweighted GPA of about 3.33. Giving both courses equal influence would produce a different result and would ignore the credit information. Now consider whether either course qualifies for a difficulty bonus under the rules you actually need. This calculator’s optional weights are illustrative. A zero-credit course is excluded from the denominator; it is not silently treated as one credit. A failed advanced course earns zero under the displayed model rather than receiving a positive difficulty bonus. Do not enter empty, negative or guessed credits just to make an overall number match a desired result. When a result differs from the transcript, compare each course, grading period, credit value and plus/minus mapping first. Schools may count repeats, pass/fail work or nonacademic courses differently. Resolve those policy differences before using the estimate on an application. Keep the original transcript authoritative and follow the receiving institution’s instructions for self-reported grades.
