Grade Needed Calculator
Find out exactly what score you need on remaining coursework to achieve your target final grade. Enter your current grade (78%), the weight of work completed (60%), and your target (85%) โ and get the answer instantly. Use Multiple for several remaining assignments with different weights.
Enter your current grade, the percentage of the course already completed, and your target final grade to find out what you need on the remaining work.
How to Use the Grade Needed Calculator
This calculator answers the most common student question: "What do I need to score on the final / remaining work to get a [target grade]?" Use What Grade for a single remaining block of work, or Multiple for several remaining assignments each with different weights.
What Grade Tab
- Enter your current grade percentage (e.g., 78%)
- Enter the percentage of the course already completed (e.g., 60% โ if you've done homework, midterms, quizzes worth 60% of the grade)
- Enter your target final course grade (e.g., 85%)
- The calculator instantly shows the exact score you need on the remaining 40% of the course.
Multiple Tab
- Enter your current grade and the weight of completed work.
- Add each remaining assignment with its name and weight percentage.
- The calculator shows the uniform score you'd need on every remaining assignment to hit your target, plus a per-assignment breakdown.
The Formula
Where weights are expressed as decimals (60% = 0.60)
Example:
Current Grade: 78%, Completed: 60%, Target: 85%
Grade Needed = (85 โ 78 ร 0.60) รท 0.40
= (85 โ 46.8) รท 0.40
= 38.2 รท 0.40
= 95.5%
Worked Examples
Example 1: You have 78% and the final exam is worth 30% of the grade. You want a B (83%).
Completed weight = 70% (100 โ 30). Grade Needed = (83 โ 78 ร 0.70) รท 0.30 = (83 โ 54.6) รท 0.30 = 28.4 รท 0.30 = 94.7%
Example 2: You have 92% and the final is worth 40%. You want an A (93%).
Grade Needed = (93 โ 92 ร 0.60) รท 0.40 = (93 โ 55.2) รท 0.40 = 37.8 รท 0.40 = 94.5%
When the Result Is "Impossible"
If the calculator shows "Impossible" or a score above 100%, it means your target grade is not mathematically achievable given your current grade and the remaining weight. To salvage the situation:
- Lower your target grade to something achievable
- Ask your professor about extra credit opportunities
- Check if any assignments can be resubmitted
- Speak with your academic advisor about your options
When the Result Is Negative or Shows "Already Achieved"
A negative result means your current grade is already so high that even scoring 0% on remaining work would still meet your target. You've mathematically secured the target grade. This commonly happens when you're going for a lower target (e.g., you want a C but already have a B+).
How to Find Your Current Weight Completed
Check your syllabus for the grade breakdown. Add up the weights of every component you've already received a grade for.
Example syllabus: Homework 20% | Quizzes 15% | Midterm 1 (15%) | Midterm 2 (15%) | Final 35%
If you've completed Homework + Quizzes + both Midterms: completed weight = 20+15+15+15 = 65%
