Final grade calculator
Working backwards from the grade you want: enter your current grade, the final exam's weight and your target, and see the exact score you need on the exam — plus the best and worst final grades possible.
Enter your current grade.
A single deterministic formula that runs in your browser — your grades are never sent to a server or AI service.
How to use
- Enter your current grade as a percentage (everything graded so far).
- Enter the final exam's weight as a percentage of the whole grade — for example 30 for 30%.
- Enter the final grade you are aiming for.
- Read the required exam score, whether the target is achievable, and the maximum and minimum possible final grade.
Private by design: this tool runs entirely in your browser — no account, no AI, and nothing you type is sent to a server.
Frequently asked questions
What formula is used?
Required exam score = (target − current × (1 − weight)) ÷ weight, with the weight converted to a decimal. With current 82, weight 30% and target 85 you need 92% on the final.
What if the required score is over 100%?
Then the target is mathematically out of reach — the calculator says so plainly and shows the maximum grade you can still finish with.
What if the required score is below zero?
You have already secured the target before the exam even starts — any score from 0 upwards keeps you at or above it.
Does this use AI or send my numbers anywhere?
No. It is a single deterministic formula that runs entirely in your browser.
