How it works
Your current grade contributes (1−w) of the course; the final contributes w. The tool solves for the final percentage that makes the weighted sum equal your target.
Formula
Required final ≈ (Target − Current × (1 − w)) ÷ w, where w is final weight as a decimal
How to use Final Grade Calculator
- Enter your current course grade as a percentage (or components if the tool splits them).
- Enter the final exam weight as a percent of the total grade.
- Set your desired overall grade.
- Read the required final exam score; impossible targets may show above 100%.
Worked examples
Concrete numbers and cases you can check against the tool above.
Need on final with 85% current, 30% final weight, target 90%
Required final ≈ (90 − 85×0.7) / 0.3 ≈ 101.7%, so a 90% course average is not reachable without extra credit.
When to use Final Grade Calculator
Students often guess required finals incorrectly by ignoring weight. This calculator applies the standard weighted-average formula so you know if a target is still reachable.
Common use cases
- Decide whether an A is still realistic before study week.
- Set a minimum final score to pass with a C.
- Compare scenarios if the final weight changes on the syllabus.
Inputs and outputs
- Percent grades
- Final weight as percent of course total

Frequently asked questions
- What if I need more than 100% on the final?
- That means the target overall grade is not achievable with the given current grade and weights.
- Does extra credit count?
- Only if you include it in the current grade you enter.
- Which other grade tools should I use?
- Use the weighted grade calculator to build your current average from assignments, and GPA calculator for term-wide credit hours.
