What score do I need on my final?
Enter your current grade before the final, the overall grade you want, and the final's course weight. The calculator keeps the completed portion of the course separate from the final and solves for the final score required to reach the target.
What-If Mode
Test a possible exam score
What-if mode applies an exam score you choose and shows the predicted course grade in real time.
Final grade formula
Convert the final exam weight to a decimal. If current grade is C, desired grade is T, and final weight is f:
Required score = (T − C × (1 − f)) ÷ f
For example, a final worth 20% uses f = 0.20.
Important assumption
This calculator assumes the current grade represents all coursework outside the final assessment. It does not assume a letter-grade scale or account for separate extra-credit rules.
Worked examples
- 92% current, 90% target, 20% final82%
- 80% current, 90% target, 50% final100%
- 95% current, 85% target, 10% final−5%
The −5% result means no positive final score is required to secure the target.
What a result above 100% means
A result above 100% is a valid mathematical outcome. For example, a current grade of 60%, a 90% target, and a final worth 20% requires 210%. Reaching that target would require extra credit.
Current-grade vs final-grade calculators
The Grade Calculator combines multiple completed weighted scores to show where you stand now. This Final Grade Calculator solves for the score needed on a remaining final assessment.
