What is the RogerHub Final Grade Calculator and how does it work?
The RogerHub final grade calculator is a small, focused tool that answers one question: given your current grade and how much your final counts, what do you need on the final to hit your target? The calculator follows the same math most schools use: weighted averages.
Formula (simple and exact)
Final Grade = (Current Grade × (1 − FinalWeight)) + (FinalExamScore × FinalWeight)We usually rewrite that to solve for FinalExamScore:
FinalExamScore = (DesiredGrade − CurrentGrade × (1 − FinalWeight)) ÷ FinalWeightIn the formula above, FinalWeight is used as a decimal (30% → 0.30). This page converts automatically.
Worked example
Say you have a current grade of 70, the final is 30% of the course, and your desired overall grade is 100:
Using the formula: FinalExamScore = (100 − 70×0.70) ÷ 0.30 = (100 − 49) ÷ 0.30 = 51 ÷ 0.30 = 170%
That result (170%) shows it’s impossible to reach 100% without extra credit. The calculator displays that clearly so students know when a target is unrealistic.
Quick table of common scenarios
| Current | Weight | Target | Needed on Final |
|---|---|---|---|
| 88 | 30 | 90 | ~96 |
| 72 | 40 | 80 | ~88 |
| 95 | 20 | 93 | ~85 |
| 70 | 30 | 100 | 170 (not possible) |
User guide — step by step
- Check your current grade from the course portal or teacher - use the number before the final.
- Confirm the final weight from the syllabus. If the final counts for 25% of the course, enter 25.
- Pick your desired overall grade (what you want the course to show after the final).
- Click Calculate — the result section shows the exact score needed, a clear explanation, and a visual breakdown.
- If the score is greater than 100%, check for extra credit options or adjust your target downward.
