Weighted Grade Calculator

What score the ungraded share of a course still needs

Weighted course grades add each assessment's score multiplied by its share of the course. A completed exam can be entered as earned/possible points, which are converted to a percent before weighting. The current average, earned course points and score needed on the remaining share answer different questions.

This page answers a course-planning question: how strong must the remaining work be to reach a chosen final percentage? A quiz at 80% with 20% course weight earns 16 of the course's 100 points; a midterm at 90% with 30% weight adds 27. An exam marked 45/50 may instead be entered as raw points: 45 ÷ 50 × 100 = 90%, then its course weight is applied. This distinction matters because 45 points earned on a 50-point exam is not 45% of the course. In the example, the completed work earns 43 course points from 50% of the course; its current average is 86%.

Earned course points, completed-work average, required remaining score and planned-score projection appear together, helping students distinguish their current standing from a future target.

How completed scores, weights, target and planned score interact

The completed rows fix how many course points you already hold. The target and the planned score are then measured against whatever weight is left.

Completed score (percent or points)

Type either a percent or an earned/possible pair such as 45/50, which becomes 90%. Typing the raw 45 alone is read as 45%, and in the example that moves the required score from 84% to an unreachable 111%. Earned points cannot exceed possible points, so extra credit has no place in this field.

Course weight

Weight is the share of the whole course an assessment carries, taken from the syllabus, not its point total. The weights of all completed rows must add to less than 100. The quiz in the example scores 80% but earns only 16 course points because it carries 20% of the grade.

Remaining weight

The tool computes this as 100 minus the completed weights, and it sets how expensive each target point is. With 50% remaining, every extra target point costs two points on the remaining work, so raising the target from 85 to 90 lifts the requirement from 84% to 94%. With only 20% left, each point costs five.

Target final grade

This is the course percentage you want, from 0 to 100, before any letter cutoff your instructor applies. If earned points already cover it, the result reads Target secured instead of a negative score; a 40% target is secured in the example because 43 course points are banked. A figure above 100% means the target is out of reach.

Planned score

This runs a separate what-if: the average you expect across all remaining work. It never changes the required figure. Planning 80% on the example's remaining half projects a final of 83%, two points short of the 85% target, which shows how far a realistic effort falls from the goal.

Steps

1. List completed assessments with a score percent or an earned/possible point pair, followed by its syllabus weight.
2. Enter your target course percentage and a plausible score for a separate final-grade projection.
3. Compare the score required on all remaining weight with the current average, converted exam score and projected final result.

Reading tip: Read the weighted assessment rows and remaining wedge together. The required score solves the target; the planned score produces a separate projection, so do not confuse the two.

How the calculation works

What every part means

scoreᵢ

Completed assessment percent, entered directly or converted from earned/possible exam points.

weightᵢ

Share of the entire course grade assigned to that completed assessment.

E / R

Course points already earned / percentage of the course still ungraded.

target / planned

Desired final percentage / separately entered scenario score on all remaining work.

Calculate it step by step

Completed rows accept either percentages from 0 to 100 or earned/possible points, with earned points no greater than a positive possible total. Their weights must total less than 100%. The required score may fall outside 0–100, revealing a secured or unreachable target rather than silently clamping the mathematics.

Interpretation & limitations

How to read your result

An 84% score on the example's remaining 50% contributes 42 course points, reaching 85 overall. Entering a planned 80% instead contributes 40 and projects 83 overall. The difference helps distinguish a goal from a scenario.

Where this estimate stops

The remaining share is treated as one combined assessment score. A syllabus with dropped work, category caps, curves, extra credit or multiple unequal future assessments requires those rules to be modeled separately.

With 48.6 points earned and a 40% final, an 80% course grade needs 78.5% on the final, while 90% would need an impossible 103.5%.
