About this calculator
'What do I need on the final?' is one of the most-searched questions every exam season, and the math behind it is simple algebra. Your final grade is a weighted blend of your current standing and the exam: if the final is worth 30% of your grade, then 70% is already locked in. This calculator rearranges that relationship to solve directly for the exam score you need.
Enter three numbers — your current grade, the final exam's weight as a percentage of the total, and the overall grade you're aiming for — and it returns the minimum score required on the final. It also tells you the two situations that matter most: when your target is already guaranteed (you could score zero and still hit it) and when it's mathematically out of reach (it would take more than 100%).
The table shows the overall grade you'd end up with for a range of possible final scores, from a perfect paper down to a zero. That's the honest picture: it turns 'I'm stressed about the final' into a concrete target, and sometimes into the reassuring discovery that the grade is already safe.
Once the term is over and grades post, use the GPA calculator to roll every course's grade and credit hours into your semester or cumulative GPA.
Frequently asked questions
How do I calculate what I need on my final?
Take your target overall grade, subtract your current grade multiplied by everything except the final's weight, then divide by the final's weight. This calculator does that automatically once you enter the three values.
What does 'final exam weight' mean?
It's the percentage of your total course grade that the final exam is worth. If the syllabus says the final counts for 25% of your grade, enter 25.
What if it says I need more than 100%?
That means the target grade is no longer mathematically reachable from your current standing, even with a perfect final. Try a slightly lower target to see what's realistic.
