Final Grade Calculator

Project the overall course grade from completed coursework, a final exam score and its weight. Enter a known or hypothetical exam score; use Required Grade to solve backwards from a target.

All grades and the exam weight range from 0 to 100%; a zero exam weight leaves the coursework average unchanged.

Calculation notes

Understand the Final Grade Calculator

Final Grade Calculator validates completed coursework average (%), final exam grade (%), final exam weight (%) before applying the displayed equation. All grades and the exam weight range from 0 to 100%; a zero exam weight leaves the coursework average unchanged.

Formula and logic

What is the formula for the Final Grade Calculator?

Final Grade Calculator: final grade = current × (1 − weight/100) + exam × weight/100. Input definitions: current = Completed coursework average (%); exam = Final exam grade (%); weight = Final exam weight (%). Use the selected convention throughout the calculation.

Worked example

How can I reproduce the Final Grade Calculator example?

Final Grade Calculator baseline input: Completed coursework average (%): 85; Final exam grade (%): 95; Final exam weight (%): 40. Output: Projected final grade = 89 %. Substitute these values into the displayed equation to reproduce the result.

How to read the result

How should I interpret the Final Grade Calculator result?

  • Read projected final grade with its stated unit and convention. The default example and the independent worked scenario use different inputs, so compare the assumptions before comparing the numbers.
  • Change one input at a time and use the equation to explain the result; do not mix unit, grade-scale, time-zone or rounding conventions across comparisons.
Limits and assumptions

What limits apply to the Final Grade Calculator?

  • All grades and the exam weight range from 0 to 100%; a zero exam weight leaves the coursework average unchanged.
  • No grading curves, extra credit, letter-grade thresholds or institution-specific rounding rules are assumed.

Four steps to check your inputs and results

  1. Project the overall course grade from completed coursework, a final exam score and its weight. Enter a known or hypothetical exam score; use Required Grade to solve backwards from a target.
  2. Enter Completed coursework average (%), Final exam grade (%), Final exam weight (%) in the stated format. Baseline values are for reproduction.
  3. Check the output unit and convention: Read projected final grade with its stated unit and convention. The default example and the independent worked scenario use different inputs, so compare the assumptions before comparing the numbers.
  4. Change one input and compare the result. All grades and the exam weight range from 0 to 100%; a zero exam weight leaves the coursework average unchanged. No grading curves, extra credit, letter-grade thresholds or institution-specific rounding rules are assumed.

Final Grade Calculator: calculation relationships

This is a forward weighted average. Coursework at 80% occupies 75% of the course and an exam at 90% occupies 25%, so the final grade is 80×0.75 + 90×0.25 = 82.5%. Enter the average of the completed portion, not an already weighted contribution of 60 points; weighting that contribution again would double-count the weight.

final grade = current × (1 − weight/100) + exam × weight/100
