What do I need on my final to pass?
Passing bar 60%, final worth 25%: with a 65% going in you need 45% on the exam. With a 52% and a 40%-weight final, you need 72%. The formula never lies; what it says about your situation is below, with the honest version of what to do when the number is over 100.

Current 65%, final worth 25%, target 60% =
45.0% needed on the final
The salvage case: 52% + 40% final → 72.0% needed.
needed = (target − current × (1 − weight)) ÷ weight
Your numbers, your verdict
| Current | Final weight | Target | Needed | Verdict |
|---|---|---|---|---|
| 65% | 25% | 60% | 45.0% | Doable |
| 58% | 25% | 60% | 66.0% | Tight but live |
| 52% | 40% | 60% | 72.0% | The salvage: needs a strong final |
| 48% | 25% | 60% | 108.0% | Not possible by exam alone |
First, check what "passing" means in your syllabus
The calculator above defaults to 60%, but passing is a local rule: some courses need a C− (70%), some programs set 65%, and a few set a hard floor on the final itself regardless of your average. A 45% on the final passes a 60%-bar course and fails a 70%-bar course with the same math. Read the syllabus line before you trust any number on this page.
When the number is over 100%: the honest math
At 48% with a 25%-weight final, the target needs 108% on the exam, which does not exist. That verdict is information, not a sentence. Three things move before the exam does: extra credit (ask now, not after the final: many professors post it early), grade forgiveness or drops (a dropped lowest quiz can lift the current grade 3–5 points, which the calculator shows you how to price), and retake policies (cheaper than failing the course twice). If none exist, the honest move is reallocating study time to courses you can still save. The ledger records what is, so you can act on it.
Estimates, not academic advice. Passing thresholds and weighting vary by course. Confirm against your syllabus.
Common questions
What do I need on my final to pass the class?
It depends on your current grade and the final's weight: with 65% going in and a 25%-weight final, 45% on the exam passes a 60% bar. Enter your numbers above for the exact figure.
What is a passing grade in college?
Usually 60% (a D) or 70% (a C−), set per course or program. Some courses add a floor: you must score a minimum on the final itself regardless of your average.
What if I need more than 100% on the final?
The exam alone cannot get you there. Ask about extra credit, dropped low scores, or grade forgiveness before the exam; if none exist, protect the courses you can still save.
How do I find my final's weight?
Your syllabus, or the grade breakdown in your LMS (Canvas, Blackboard). Finals commonly weigh 20–40%.
