Limits and Important Notes
How the Grade Calculator Works
For a points-based class, the calculator divides total points earned by total points possible. For a weighted class, it multiplies every category grade by that category's decimal weight and adds the contributions.
To calculate the grade needed on a final, the tool subtracts the completed-work contribution from the target course grade and divides the remainder by the final exam weight.
Formula
Points grade = earned ÷ possible × 100; weighted grade = Σ(grade × weight) ÷ Σ(weights); required final = [target − current × (1 − final weight)] ÷ final weight
Example
If your current grade is 87%, your target is 90%, and the final is worth 30%, you need 97% on the final: [90 − 87 × 0.70] ÷ 0.30 = 97.
- The common A–F estimate uses 90/80/70/60 cutoffs, but your school or instructor may use a different grading scale.
- Dropped scores, curved grades, extra credit rules, category caps, and instructor rounding are not applied automatically.
- The final-grade mode assumes the current grade represents all work completed before the final and that no other assignments remain.
- A result above 100% is mathematically correct for the entered target but may be impossible without extra credit.
