Final Grade Calculator

Your final grade is a weighted average: overall = current grade × (1 − weight) + final score × weight, with the weight written as a decimal. Rearranging that gives the score you need: needed = (target − current × (1 − weight)) ÷ weight. For example, with a 78% current grade, a final worth 40%, and an 80% goal, you need (80 − 78 × 0.6) ÷ 0.4 = 83% on the final.

If the parts are graded together as one block, add their weights and enter the total — the result is the average you need across all parts. If they're weighted separately and you expect to do better on one than another, run the calculator once per part, entering your current grade with the other parts excluded. The single-number answer is a target average, not a per-exam requirement.

Check the grading breakdown section of your syllabus — most list something like "Final Exam: 30%", and that number is your weight. If your course uses points instead of percentages, divide the final's points by the total course points (a 200-point final in a 1,000-point course is a 20% weight). If the syllabus doesn't say, email your instructor or check the course page — guessing the weight is the most common way this calculation goes wrong.

No — it shows the exact math to one decimal place. Many instructors round 89.5% up to an A or curve the final, but neither is guaranteed, so don't plan around it. Treat the number here as the honest minimum and aim a few points above it.

Usually, but it depends on your school. At most US colleges 60% is a D, which counts as passing for general credit — yet many programs require a C (70%) or better in major courses, and some pass/fail classes set their own line. Check your syllabus or student handbook before treating 60% as safe.

Then there's nothing left to calculate — your current grade essentially is your final grade, aside from any remaining assignments. This tool only helps when one big weighted exam is still outstanding. If you have smaller assignments left instead, each one moves your grade by its own (smaller) weight.

Often, yes — remaining homework, quizzes, labs, or extra credit all feed the "current grade" side of the equation. Every point you add there lowers what you need on the final, and those points are usually easier to earn than exam points. Recompute here after each grade posts so your target stays accurate.

Because even a perfect 100% on the final wouldn't lift your weighted average that high. The best you can finish with is current × (1 − weight) + 100 × weight, and if your target sits above that ceiling, no final-exam score gets you there. The calculator shows that maximum so you can set a goal that's actually on the table.
