Grade Calculator
Two calculators in one: turn a score (correct out of total) into a percentage and letter grade, or work out the grade you need on your final exam to reach a target.
How to use
In 'Score → grade' mode, enter how many you got right and the total — get the percentage and letter grade instantly.
In 'Grade needed on final' mode, enter your current grade, how much the final is worth, and your target — it shows the percentage you need on the final.
FAQ
How is my percentage calculated?
Correct answers divided by total, times 100. For example, 45 out of 50 is 90%.
What grade do I need on the final?
Enter your current grade, the final's weight and your target; the tool solves for the score you need. Over 100% means the target isn't reachable from the final alone.
What grading scale is used?
A common US letter scale (A ≥ 90%, B ≥ 80%, and so on, with + and −). Your school's cutoffs may differ slightly.
