Required Grade Calculator
A required grade calculator goes beyond a single upcoming assignment and answers the broader question: given where you are in the course right now, what do you need to score on each of your remaining assignments to pass or hit a target grade? Students with several assignments, quizzes, or exams still ahead often need this kind of forward-looking view to understand exactly how much effort is required. The tool takes four inputs: your current average in the course (excluding remaining assignments), the grade you need to finish with (often 60% or 70% to pass), the number of remaining assignments, and the percentage weight each of those assignments carries in the final grade. It then applies the inverse weighted-average formula to find the minimum score required on each remaining assignment, assuming you score the same on all of them. The result also shows the total weight still outstanding, the letter grade corresponding to the required score, and a clear achievability flag. If the required score is above 100%, the calculator says so immediately. This is a more complete view than asking about a single exam, because it shows you where you stand with the full picture of remaining work in front of you. Results update live as you type.

How the required grade formula works
With multiple equally weighted remaining assignments, the total remaining weight is the number of assignments multiplied by each weight. The required score on each is solved from the weighted average formula.
Total remaining weight = Number of assignments x Each weight (%)
Required score = (Target - Current x (1 - Total remaining weight/100)) / (Total remaining weight/100)
Worked example
Current average: 72%. Target: 70%. Remaining: 3 assignments, each worth 10% (total 30%).
- Total remaining weight: 3 x 10 = 30%
- Completed work weight: 1 - 30/100 = 0.70
- Contribution from completed work: 72 x 0.70 = 50.4
- Points needed from remaining work: 70 - 50.4 = 19.6
- Required score per assignment: 19.6 / (30/100) = 19.6 / 0.30 = 65.33%
- 65.33% corresponds to a D. This is achievable.

Required grade calculator: frequently asked questions
How do I calculate what I need to pass with multiple assignments remaining?
The formula distributes the remaining gap across all assignments equally. First, find the total weight remaining (number of remaining assignments times each assignment's weight). Then solve: required score per assignment = (target grade - current grade x (1 - total remaining weight/100)) / (total remaining weight/100). This gives the score needed on each assignment, assuming you score equally on all of them.
What if each remaining assignment has a different weight?
This calculator assumes all remaining assignments carry the same weight. If weights differ, use the missing grade calculator for each one individually, updating your running grade after each result. For complex scenarios with many differently weighted assignments, a weighted grade calculator is the most flexible approach.
What does 'minimum score needed total' mean?
The minimum score needed total is the same as the required score per assignment when all assignments carry equal weight. It represents the percentage you must average across all remaining assignments to hit your target. If that number exceeds 100%, your target is not achievable regardless of how well you perform on the remaining work.
What does the achievability indicator show?
The achievability check compares the required score against 100%. If the required score is 100% or below, the goal is achievable with perfect or near-perfect performance. If it exceeds 100%, you cannot reach the target through the remaining assignments alone. This is a useful signal to either lower your target, explore extra credit options, or speak with your instructor.
Does this calculator work for pass/fail courses?
Yes. Enter the minimum passing percentage for your course as the target grade. If your institution's passing threshold is 70%, enter 70 as the target. The calculator then tells you what you need on each remaining assignment to clear that threshold. This works for any target grade, not just letter-grade scenarios.
