Final Grade Calculator
Find out what grade you need on your final exam to reach your target course grade, based on your current grade and the final's weight.
How it works
Required final grade formula
Needed = (Desired − Current × (1 − w)) / w w = weight of the final as a decimal
Your final course grade is a weighted blend of your current grade and your final exam. Rearranging that blend to solve for the exam score tells you exactly what you need. If the answer is above 100% the target is out of reach; if it is zero or negative, you have already earned it.
Worked example
With an 85% current grade, a 90% target, and a final worth 30%: needed = (90 − 85 × 0.70) / 0.30 = 101.7%. That target isn't reachable without extra credit — lowering the goal to 88% would need 92.0% on the final.
Frequently asked questions
What does 'current grade' mean here?
It's your grade in the course so far, covering everything except the final exam. The final's weight is what remains of the total — so if the final is 30%, your current grade represents the other 70%.
What if the result is over 100%?
It means your target is not mathematically reachable through the final alone. You would need extra credit, or you should adjust your target to something achievable.
What if the result is negative?
A negative or zero requirement means you've already locked in your target grade — you could score nothing on the final and still meet it.
