What this calculator does

The Grade Needed Calculator tells you the average score you must earn on the work you have not yet completed — your remaining assignments, projects, or final exam — in order to finish the course at a target grade. Instead of guessing, you get a clear number to aim for.

How to use it

Enter three values: your target final grade (the percentage you want overall), your current grade so far (the average on work already graded), and the weight of work already completed as a percentage of the whole course. The calculator returns the average percentage you need on the remaining weight.

The formula explained

The course is treated as 100% of weight. The points you have already secured equal your current grade times the completed fraction. Subtract that from your target to see how many points must still come from the remaining work, then divide by the remaining weight fraction:

$$G = \frac{\text{Target (\%)} - \text{Current (\%)} \cdot c}{1 - c} \quad\text{where}\quad c = \frac{\text{Completed (\%)}}{100}$$

If the result is above 100%, your target is no longer reachable from the remaining work alone. If it is at or below 0%, you have already locked in your target.

Your course splits into the completed portion and the remaining portion that still needs a score.

Worked example

You want a final grade of 90%. You currently average 85%, and that covers 70% of the course. Points secured = \(85 \times 0.70 = 59.5\). Remaining weight = 30%. Needed:

$$G = \frac{90 - 59.5}{0.30} = \frac{30.5}{0.30} = 101.67\%$$

Since that is above 100%, the 90% target is just out of reach unless extra credit is offered.

The needed score closes the gap between your current standing and your target grade.

FAQ

What if the result is negative? A negative or zero result means you have already earned enough to hit your target — you only need to score 0% (or above) on what's left.

What if I've completed 100% of the course? There is no remaining work to influence your grade, so the tool reports 0% needed; your final grade is already locked in.

Does this handle weighted categories? It works on the overall course weight. Combine all completed categories into one "current grade" and their combined weight into "completed" for an accurate single answer.
