Final Exam Grade Calculator

How it works

Final exam grade calculator: what score do you need?

Choose Required final score and enter your current grade before the final, your target overall grade, and the final exam weight. Required final score = (target grade − current grade × (1 − exam weight / 100)) / (exam weight / 100). Your current grade must exclude the final; do not use a grade that already counts an ungraded final as zero.

For example, an 85% current grade, an 88% target, and a final worth 30% require 95% on the exam. A result above 100% is flagged as unattainable without extra credit. A negative result means the target is already secured even with a zero on the final under these weights. Displayed values are rounded to two decimal places; use your course’s rounding and completion rules.

Required final score: formula and assumptions

Required final = [target−current×(1−final weight)]/final weight.

A required score above 100% means the target cannot be reached without extra credit under these assumptions.

Required final score with letter inputs: formula and assumptions

Required score = [target − current × (1 − remaining share)] / remaining share.

The mathematical result can exceed 100 or be negative. Letter inputs use the editable representative-score map.

Worked example

Using the Required final score example:

Current grade (%)

85

Target overall grade (%)

90

Final assessment weight (%)

30

Required final = [target−current×(1−final weight)]/final weight.

Example result

• The target requires more than 100% on the remaining assessment. Lower the target or check whether extra credit is available.

These are illustrative inputs. Change the values to explore a different scenario.
