Districts and colleges weight dual enrollment differently on transcripts. Use the same credit unit (e.g. semester hours) in both pools, and exclude pass/fail work that does not carry GPA quality points.
Blended GPA (HS + DE)
3.61
34 graded credits combined
Δ vs HS-only GPA

DE share: 35%
HS QP: 78.1 · DE QP: 44.6

Holistic GPA snapshot
Useful when you want a single GPA figure that reflects both traditional and college-earned grades.
Use case
Impact storytelling
Shows whether dual enrollment is currently helping or hurting the numeric blend on your inputs.
Diagnostic
College credit %
Higher DE share means college grades move the blended GPA faster.
Formula layer
GPA × credits
Explains why a few high-credit DE courses can swing the combined GPA meaningfully.
Reminder
One pool per credit
Each graded credit should appear in only one segment unless your local rules explicitly model otherwise.
Holistic note
Beyond the average
Admissions readers evaluate trend, rigor, and fit—not GPA alone.
HS-only GPA 3.55 on 22 credits plus DE GPA 3.72 on 12 credits:
Blended GPA
3.61
Δ vs HS-only
+0.06
The calculator multiplies each segment GPA by its graded credits to obtain quality points, sums the points, and divides by total graded credits. When both segments contain credits, the displayed delta is the blended GPA minus your high-school-only GPA, matching the intuition behind cumulative blending in our cumulative GPA calculator.
Blended GPA = (HS GPA × HS credits + DE GPA × DE credits) ÷ (HS credits + DE credits)Delta versus HS-only appears only when both credit pools are greater than zero.
Result: blended GPA ≈ 3.53 with +0.13 lift versus HS-only
DE represents one-third of graded credits here, so strong college grades move the combined average noticeably.
