What's the difference between weighted and unweighted grades?

Weighted grades assign different importance (weights) to different assignments, while unweighted grades treat all assignments equally. Weighted averages give more impact to assignments with higher weights.

How do I calculate what grade I need on the final exam?

Enter your current assignment grades and weights, then enter your target overall grade. The calculator will show you the minimum grade needed on the final exam to achieve your target.

Can I use this for letter grades?

Enter percentage grades only. The letter uses this scale with no plus or minus: A at 90 or above, B at 80, C at 70, D at 60, otherwise F.

What if my weights don't add up to 100%?

Assignment weights are divided by their own total, so they do not have to sum to 100. The final-exam formula treats that average as the non-final share of the course.

Smart Tips

• Focus on assignments worth the most points to maximize your grade impact and overall course performance.

• Ask for extra credit opportunities if you're close to your target grade to boost your final score.

• Review graded work to understand expectations and improve future assignments based on feedback.

• Submit assignments on time to avoid late penalties that impact your grade and course standing.

Key Insights

Weighted vs Unweighted Grades

Weighted grades account for assignment importance (tests worth more than homework), while unweighted grades treat all assignments equally. Weighted grades better reflect course performance and overall achievement.

Final Exam Impact & Planning

The higher the final exam weight, the more impact it has on your overall grade. Use this calculator early to determine what grade you need on the final to achieve your target course grade.

Grade Planning & Prioritization

Use this calculator early in the semester to plan which assignments to prioritize. Focus on high-weight assignments and exams to maximize your grade impact throughout the course.

Target Setting & Goal Achievement

Set realistic target grades based on your current performance and remaining assignments. The final-exam line treats the current average as the non-final share of the course. It is not a plan for every remaining assignment.

Frequently Asked Questions

Multiply each grade by its weight (percentage), sum all weighted grades, then divide by total weight. Our calculator handles this automatically when you enter grades and their weights.

Weighted grades account for assignment importance (tests worth more than homework), while unweighted grades treat all assignments equally. Weighted grades better reflect course performance.

Enter assignment percentages and weights, then a final-exam weight and a target percentage. The current average is treated as the grade on the non-final share of the course: required final = (target − current × (100 − final weight) / 100) / final weight × 100. Below 0% is “Already achieved”. Above 100% is “Impossible”. If the assignments already cover the whole course, leave the final weight blank.

Enter grades as percentages from 0 to 100. The letter is assigned after the average on this percentage scale: A at 90 or above, B at 80, C at 70, D at 60, otherwise F. There is no plus or minus, and letter grades are not an input.

Our calculator uses standard mathematical formulas for weighted averages. Results are accurate to multiple decimal places, but always verify with your teacher's grading system for exact calculations.

Calculate each course separately using this calculator. Enter all assignments for one course at a time to get accurate weighted averages and determine what grades you need on remaining assignments to reach your target grade.

For dropped grades, exclude them from your calculations. For extra credit, add it as an additional assignment with its weight. Adjust your total weight percentage accordingly to reflect your course's actual grading structure.

The average is Σ(grade × weight) / Σ(weight). Weights do not have to sum to 100. The letter cutoffs and the final-exam formula are the ones in the formula table on this page. Source: NCES GPA/grade context: https://nces.ed.gov/nationsreportcard/hsts/howgpa.aspx.
