Calculate a 100%-reconciled weighted grade or solve the raw final-exam score needed from current average, final weight, and target.
A quick decision brief for this specific tool
Named grading categories with 0–100 scores and weights totaling exactly 100%; target mode also uses a final-exam category and optional current pre-final average
Weighted percentage, model letter/GPA mapping, category range, and raw final score needed with achievable/unachievable state
Sum of grade × weight divided by 100; target-final algebra weights the current pre-final average by the completed share (100% minus final weight)
Choose your path
Calculate a syllabus-weighted course grade only when weights reconcile to 100%, or solve the raw final-exam score needed using the completed share of the course.
Combine category grades without silently normalizing incomplete weights.
Enter named categories, 0–100 scores, and weights; then correct any total other than exactly 100%.
Receives a reproducible weighted result only after the syllabus allocation reconciles.
Know the score required on a final worth a specific share of the course.
Switch to target mode, enter current pre-final average and target, and use the named Final category weight.
Sees 97.5% for current 85%, target 90%, and a 40%-weight final—not the prior erroneous 12.5%.
Edit categories and compare a planning scale without clipped or ambiguous controls.
Use named category fields, presets, mode actions, and the visible letter/GPA model caveat.
Can complete the calculation on a phone and understands the scale is not an official transcript policy.

Every category contributes its score multiplied by its percentage weight. The panel requires the weights to reconcile to exactly 100%.
Course grade = Σ(category score × category weight) ÷ 100Multi-step calculations show intermediate values so you can audit each stage. This transparency helps catch data-entry errors before relying on the final number.
The current pre-final average applies only to the completed share of the course, not to 100% of the course.
Needed final = (Target × 100 − Current × (100 − Final weight)) ÷ Final weightUpdated: August 2026
With an 85% pre-final average, a final worth 40%, and a 90% target, the required final score is 97.5%.
A teacher or student uses the Grade Calculator to verify homework, demonstrate formulas, or explore what-if scenarios in class.
A student finds category weights total 95%; the panel blocks the overall result until the syllabus allocation is corrected or completed.
Build a category plan whose weights total exactly 100%, or calculate the final score needed. Letter and GPA mappings are planning conventions; verify the instructor's weights, rounding, extra credit, and grading scale.
