Remaining weight
Final Exam Grade Needed Calculator
When the syllabus lists weighted categories, the final exam is often the last lever you can pull. This grade calculator works backwards from your target overall percentage and the scores and weights of the work you have already completed. The result tells you the minimum score you need on the remaining exam so you can study with a clear number in mind instead of guessing.
Please enter valid scores and weights (weights > 0).

Needed average on remaining work
How to Use the Grade Calculator
- Add a row for each completed assignment or test: your score (%) and its weight (%).
- Enter the overall percentage you want in the optional target box.
- Calculate to see your current weighted grade and the weight still remaining.
- Read the average you need on the remaining work to reach your target.
Use one row per completed item and add rows as needed. Scores run from 0 to 100, and each weight is that item’s share of the whole course. The weights you enter cannot add up to more than 100%. What is left (100 minus the total) is the remaining weight, usually the final exam. Leave the target empty to see only your current grade.
Grade Calculator Formula Explained
Required Final = (Target − Current × (1 − Final Weight)) ÷ Final Weight
Let C be the current average as a decimal, W the final’s weight as a decimal, and T the target course grade. Required final score R satisfies C(1 − W) + R·W = T, which rearranges to R = (T − C(1 − W)) ÷ W. If R exceeds 100%, the target is unreachable with the remaining weight. If R is negative or very low, the target is already secured or nearly secured.
The calculator adds up score × weight for every row to get your current weighted grade. It then solves for the average you need on the remaining weight: (target × 100 − points earned) ÷ remaining weight. If that average is above 100%, it tells you the target needs more than 100% on the remaining work. If no weight is left, it shows that instead of a number.
Grade Calculator Example Calculation
If coursework averages 72% and the final exam is worth 40% of the module, reaching an overall 70% requires a final exam score of 67%. If the required score exceeds 100%, the target is not reachable with the remaining weight alone.
Worked example: enter one row with a score of 72 and a weight of 60, and a target of 70. The current weighted grade is 72.00%, the remaining weight is 40.00% and the needed average is 67.00%. With two rows, 80 at weight 25 and 64 at weight 35, and a target of 75, the current grade is 70.67% and you need 81.50% on the remaining 40.00%. A target of 90 would need 119.00%, which is not reachable.
When to use this tool
Use this before exam periods to prioritise revision time based on the minimum score still needed.
Key Features & Benefits of This Grade Calculator
- Works backwards from your target — enter the overall percentage you want and see the average you need on the remaining work.
- Weighted scores — each row takes a score and its weight, so tests, coursework and projects count in proportion.
- Current grade and remaining weight — see your weighted grade so far and how much of the course is still to come.
- Honest about unreachable targets — if the needed average is above 100%, the calculator tells you the target needs more than 100% on the remaining work.
- Instant, free and private — runs entirely in your browser, no sign-up, nothing stored.
Good to know
Module handbooks usually state whether the final is capped, must be passed independently, or can be compensated. Read those rules alongside the numeric target this tool provides.
Grade Calculator — FAQs
What if I have more than one remaining assessment?
Combine their weights into a single remaining weight, or run the calculator once per remaining item in sequence.
Does this work with points instead of percentages?
Convert everything to percentages of the course total first, or scale the formula to raw points consistently.
Can the required score be over 100%?
Yes, mathematically. That signals the target is impossible given current performance and remaining weight.
Should I include extra credit?
If extra credit is already reflected in your current average, leave the inputs as they are. If it is still pending, treat it as additional remaining weight.
