Final Grade Calculator
Find the score you need on your final exam to reach the course grade you want, from your current grade and how much the final counts.
Final Grade Calculator: Your course grade is a weighted average: the grade so far counts for 100% minus the final's weight, and the final counts for the rest. The calculator solves that average for the final score: with 85% so far, a final worth 30%, and a target of 90%, you need (90 − 0.7 × 85) ÷ 0.3 = 101.7% on the final, which is out of reach without extra credit.

| For a course grade of | You need on the final |
|---|---|
| 90% | Not reachable |
| 80% | 68.3% |
| 70% | 35% |
| 60% | 1.7% |
Course grade = current grade × (100% − final weight) + final score × final weight. If your teacher drops the lowest score or curves results, the real figure may differ.
Weighted categories
Many courses weight categories, such as homework 20%, tests 50%, and the final 30%. Your current grade is then the weighted average of the categories so far, rescaled to 100%: with 90% on homework and 80% on tests, it is (0.2 × 90 + 0.5 × 80) ÷ 0.7 = 82.9%.
For a single test's percentage from points, use the test grade calculator; for an overall average across courses, the GPA calculator.
Planning your revision
Once you know the score you need, a study planner can share out the days before the exam, giving more time to the subjects where you need the biggest improvement.

Frequently asked questions
What if my grades are points, not percentages?
Convert them first: points earned divided by points possible, times 100. If the final is worth a set number of points rather than a percentage, its weight is its points divided by the course's total points.
What does a result over 100% mean?
That even a perfect final cannot lift your grade to the target. Aim for the next target down, or ask whether extra credit or dropped scores apply.
Does this work with letter grades?
Yes, using your school's percentage cut-offs: in many US schools an A starts at 90%, a B at 80%, a C at 70%, and a D at 60%, as in the table.
