A complete worked example

Consider an English class weighted as: Homework 20%, Quizzes 15%, Midterm 25%, Participation 10%, Final 30%. You have done everything except the final. Scores: Homework 92%, Quizzes 85%, Midterm 78%, Participation 95%.

Step by step

Homework 92 x 0.20= 18.40
Quizzes 85 x 0.15= 12.75
Midterm 78 x 0.25= 19.50
Particip. 95 x 0.10= 9.50
Total (70% complete)60.15
Average 60.15 / 0.7085.9% (B)

What you need on the final

A (93%)109.5% (no)
A- (90%)99.5% (no)
B+ (87%)Need 89.5%
B (83%)Need 76.2%
B- (80%)Need 66.2%
C+ (77%)Need 56.2%

Formula: Required = (Target x 1.00 - Weighted Points) / Remaining Weight. For B+: (87 - 60.15) / 0.30 = 89.5%.

Category weighting vs individual assignment weighting

Your syllabus uses one of two systems. Category weighting groups assignments under a single weight: if homework is worth 20% across 10 assignments, each individual homework is effectively 2% of your grade. The 10 homeworks are averaged first, then that average counts as 20%.

Individual assignment weighting lists every assignment separately with its own explicit weight. Homework 1 is 3%, Homework 2 is 4%, Midterm 25%, and so on. All weights add up to 100% on their own.

For category-weighted classes, average all grades within each category first, then enter each category as a single row in the calculator. For individually-weighted classes, enter every assignment as its own row. Both approaches give the same final answer.

Extra credit, dropped grades, late penalties

Extra credit

Enter scores above 100% directly. A 105% homework on a 20% weight contributes 21 points instead of the normal 20. The math handles overshoots correctly. Some courses cap individual scores at 100%, so check the syllabus before assuming a 110 sticks.

Dropped lowest grade

Manually remove the lowest score before entering the category average. If 7 of 8 quizzes count and the lowest is dropped, average the top 7 and enter that as the quiz row. The calculator does not auto-drop, so do this step by hand.

Late penalties

Apply the penalty before entering the score. A 95 with a 10% per day penalty for one day late becomes 95 x 0.90 = 85.5. Stack penalties for multiple days. The assignment impact calculator has a dedicated late penalty tool.

Frequently asked questions

How do I calculate my weighted grade?+
Multiply each assignment grade by its weight (as a decimal), then add them all up, then divide by the total weight. Example: Homework (92%, weight 20%) + Midterm (78%, weight 30%) + Quizzes (85%, weight 15%). Calculation: (92 x 0.20) + (78 x 0.30) + (85 x 0.15) = 18.4 + 23.4 + 12.75 = 54.55. Total weight: 0.20 + 0.30 + 0.15 = 0.65. Weighted average: 54.55 / 0.65 = 83.9%. This is your current average based on the 65% of your grade that has been completed.
What do I need on the final to get an A?+
Use this formula: Required Score = (Target Grade x Total Weight - Current Weighted Points) / Final Weight. Example: You want a 93% (A). Your current weighted points (from completed work) are 54.55 out of 65% weight. The final is worth 35%. Required = (93 x 1.0 - 54.55) / 0.35 = 38.45 / 0.35 = 109.9%. If the required score exceeds 100%, the target grade is mathematically impossible with remaining assignments alone. In this case, you would need extra credit or a different target.
Does 89.5% round up to an A-?+
This depends entirely on your professor or school policy. Many institutions use standard rounding (89.5% rounds to 90%, which is typically an A-). Others use strict cutoffs (89.9% is still a B+). Some professors specify in their syllabus whether they round. If the syllabus does not mention rounding, assume strict cutoffs and aim for the full grade threshold. When in doubt, ask your professor directly. It is better to know the policy before finals week than to be surprised after grades are posted.
My teacher says homework is 20% but I have 15 homework assignments. How does that work?+
When homework is weighted at 20% as a category, all 15 assignments are averaged together first, then that average counts as 20% of your total grade. If your 15 homework scores average to 88%, the homework category contributes 88% x 0.20 = 17.6 points toward your final grade. Each individual homework assignment is worth 20% / 15 = 1.33% of your total grade. Missing one homework out of 15 would reduce your homework average by roughly 6.7 percentage points (assuming the missed assignment is a 0), which reduces your final grade by about 1.3 points.
How do weighted grades differ from unweighted grades?+
Unweighted grades treat every assignment equally regardless of its importance. If you have 10 homework assignments and 1 final exam, each counts as 1/11 of your grade. Weighted grades assign different importance to different assignments. The final exam might be worth 30% of your grade while each homework is worth 2%. Weighted grading more accurately reflects the course structure because a final exam typically assesses deeper understanding than a single homework assignment. Most college courses and many high school courses use weighted grading.
What happens if my professor drops the lowest grade?+
When the lowest grade in a category is dropped, remove that score before averaging the remaining assignments. If you have 10 quiz scores (85, 90, 72, 88, 95, 80, 91, 86, 78, 93) and the lowest is dropped, remove the 72 and average the remaining 9 scores: (85+90+88+95+80+91+86+78+93) / 9 = 87.3%. Without dropping: (sum including 72) / 10 = 85.8%. The dropped grade raised your quiz average by 1.5 points. This calculator does not automatically drop lowest grades, so manually remove the lowest score from the relevant category.
How do I account for extra credit?+
Extra credit increases your grade beyond the normal maximum. If your homework category has a maximum of 100 points per assignment and your professor offers 5 extra credit points on one assignment, your score might be 105/100 = 105%. Enter this as 105 in the grade field. The weighted calculation handles it correctly. A 105% on a homework worth 20% contributes 21.0 points instead of the normal maximum of 20.0 points. Some professors cap grades at 100% even with extra credit, so check the syllabus.
How is weighted GPA different from my class grade?+
Your weighted class grade (what this calculator computes) shows your percentage in a single class based on assignment weights. Weighted GPA is a separate concept used across multiple classes: it adds extra GPA points for advanced courses. In a standard 4.0 GPA scale, an A is worth 4.0. In a weighted GPA system, an A in an AP class is worth 5.0 and an A in an Honors class is worth 4.5. Weighted GPA rewards students for taking harder courses. A student with a 4.3 weighted GPA has taken advanced courses and earned high grades.
