Calculate what you need on your final, weighted averages, semester grades, and curved grades — instantly.
What score do you need on your final exam?
Final Grade Calculator
Our final grade calculator tells you exactly what score you need on your final exam to reach your target grade. Enter your current class grade, the grade you want to finish with, and the weight of your final exam. The calculator instantly shows the minimum score you need — no guesswork, no complicated math.
This is the most-searched grade calculator tool online, because every student asks the same question before finals week: "What grade do I need on my final?" Our finals grade calculator answers that in seconds.
How to Calculate Your Final Grade
The formula to calculate your final grade is:
Final Exam Score Needed = (Desired Grade − Current Grade × (1 − Final Weight)) / Final Weight
Example: You have an 85% in the class. You want a 90%. Your final exam is worth 30% of your grade. You need: (90 − 85 × 0.70) / 0.30 = 101.67%. In this case, you'd need over 100% on the final — which means a 90% is likely out of reach. Our grade calculator final tool shows this instantly so you can adjust your target.
Weighted Grade Calculator
The weighted grade calculator computes your overall grade when assignments have different weights. Homework might be 20% of your grade, quizzes 15%, the midterm 25%, and the final 40%. A grade calculator with weights multiplies each score by its percentage, sums them up, and divides by the total weight.
Grade Calculator with Weights — How It Works
- Enter each assignment or category with its grade and weight
- Add as many rows as you need
- Your grade weight calculator result updates in real time
Formula: Weighted Average = (Grade₁ × Weight₁ + Grade₂ × Weight₂ + ...) / (Weight₁ + Weight₂ + ...)
Example: Homework 92% (20% weight) + Midterm 78% (30% weight) + Final 88% (50% weight) = (92×20 + 78×30 + 88×50) / 100 = 85.8% (B).
Semester Grade Calculator
The semester grade calculator works like the weighted grade calculator but is organized by grading categories for an entire semester. Enter each category your syllabus lists — homework, participation, quizzes, midterm exams, projects, and the final exam — with the grade you earned and the weight it carries.
How to Calculate Your Semester Grade
- Check your syllabus for each category and its weight percentage
- Enter your grade in each category
- The semester grade calculator shows your overall semester average
Most professors break semester grades into 4-6 categories that add up to 100%. If your weights don't add up to 100%, the calculator automatically normalizes them.
Grade Average Calculator
Need a simple grade average calculator? Use the weighted grade tab and set all weights to the same value (e.g., 1 or equal percentages). The calculator gives you the arithmetic mean — the unweighted average of all your grades. This is useful when all assignments count equally, like calculating your average quiz score or average test grade across the semester.
Grade Curve Calculator
A grade curve calculator adjusts your raw score based on a curve applied by your professor. Our tool supports two curve types:
- Flat curve: A fixed number of points added to every score (e.g., +5 points). If you scored 72%, a +5 flat curve brings you to 77%.
- Percentage curve: A percentage increase applied to your raw score (e.g., +10%). If you scored 72%, a +10% curve brings you to 79.2%.
Grade curves are common in college courses where the class average is lower than expected. The grade curve calculator shows your adjusted grade and letter grade instantly.
Letter Grade Scale
| Letter | Percentage | GPA |
|---|---|---|
| A+ | 97–100% | 4.0 |
| A | 93–96% | 4.0 |
| A- | 90–92% | 3.7 |
| B+ | 87–89% | 3.3 |
| B | 83–86% | 3.0 |
| B- | 80–82% | 2.7 |
| C+ | 77–79% | 2.3 |
| C | 73–76% | 2.0 |
| C- | 70–72% | 1.7 |
| D+ | 67–69% | 1.3 |
| D | 63–66% | 1.0 |
| D- | 60–62% | 0.7 |
| F | 0–59% | 0.0 |
Frequently Asked Questions
How do I calculate my final grade?
Use the Final Grade tab above. Enter your current grade, the grade you want, and your final exam's weight (check your syllabus). The final grade calculator shows the exact score you need on your final exam. If the result is over 100%, you'll know that grade isn't reachable and can adjust your target.
What grade do I need on my final?
That depends on your current grade and how much your final exam is worth. For example, if you have an 80% and the final is worth 40%, you'd need a 95% on the final to finish with an 86%. Use our grade calculator final tool to find your exact number.
How do I calculate a weighted grade average?
Multiply each grade by its weight, add up all the products, then divide by the total weight. Our weighted grade calculator does this automatically. Enter your grades and weights, and the result updates in real time.
How does a grade curve work?
A grade curve adjusts scores to account for a difficult test or low class average. A flat curve adds the same points to everyone (e.g., +5). A percentage curve increases each score by a percentage (e.g., +10%). Use our grade curve calculator to see your adjusted grade instantly.
What is a semester grade?
Your semester grade is the weighted average of all grading categories across the semester — typically homework, quizzes, midterms, projects, and a final exam. Each category has a weight (percentage of your total grade) defined in the syllabus. Our semester grade calculator computes this for you.
How to calculate grade average?
For a simple (unweighted) grade average, add up all your grades and divide by the number of grades. For a weighted average, use our grade average calculator — enter your grades with their respective weights and get the result instantly.
