Grade Calculator

Get a clear picture of your standing in a class-this tool combines finished assignments, category weights, and grading rules to show your up-to-the-moment course average. It’s especially helpful mid-term or before finals, when you need to see which categories carry the most influence and where an extra few points could make the biggest difference.

The Grade Calculator lets you model weighted categories, account for dropped scores, and run “what-if” scenarios for remaining work. The goal is simple: know exactly what scores are needed to hit a target grade so you can prioritize study time, avoid surprises, and finish the term with confidence.

Calculate your course grade with weighted categories or points - and see your percent and letter grade live.

Steps to calculate Weighted Grade

  1. 92.00% × 20.00% = 18.40Multiply grade by its weight
  2. 88.00% × 20.00% = 17.60Multiply grade by its weight
  3. 85.00% × 60.00% = 51.00Multiply grade by its weight

Grade results interpretation

  • Weighted mode: If weights don’t sum to 100%, the calculator normalizes to the sum you entered.
  • Points mode: Uses total earned ÷ total possible × 100.
  • Letter grades: Typical U.S. thresholds are shown; check your syllabus for exact cutoffs.

How this calculator works

In Weighted %, the tool computes a weighted average of your category grades. In Points, it computes your overall percentage from total points.

Show math

Weighted: overall = Σ(gradeᵢ × weightᵢ) ÷ Σ(weightᵢ)

Points: overall = (Σ earnedᵢ ÷ Σ possibleᵢ) × 100

Assumptions: no dropped scores; weights represent final course proportions; points are comparable across assignments.

FAQ

Do weights have to sum to 100%?

No, the tool normalizes whatever you enter, but instructors usually specify 100%.

Can I mix points and weights?

Pick one method per course for consistent results.

How precise are the results?

We show two decimals; policies may round differently.

What if an assignment is missing?

Leave it out or enter its points as 0 of N to model the impact.

Why is my letter grade different from my LMS?

Schools vary in cutoffs and rounding; check the syllabus.

Does extra credit change the denominator?

It depends on your policy-model it by adding a row with points.

Use cases & examples

  • Weighted: 92% (20%), 88% (20%), 85% (60%) → overall ≈ 86.6%
  • Points: 135/150, 90/100, 45/50 → overall ≈ 89.44%
  • What-if: Add a row with “Final Exam” and try different scores to see outcomes.

What this Grade Calculator does

Our grade calculator tool helps you translate assignment results into a clear course percentage and letter grade. Our calculator supports two common models: weighted categories (e.g., Homework 20%, Quizzes 20%, Exams 60%) and points-based courses where every assignment adds to a running total.

How to use it: pick a mode, add rows, and type scores. Your overall grade updates live in the green banner. The amber panel shows the math for transparency, which is useful when you’re checking a syllabus or comparing to your LMS.

Weighted vs. points-what’s the difference?

In a weighted course, category percentages reflect how much each part counts. In a points course, each assignment’s possible points determine its influence. Neither is “better”-they’re just different systems. Always model your course the way your instructor describes it.

Interpreting your results

Two decimals are usually enough for decisions (e.g., 89.50%). Many instructors round at the end, but some round each component first. If a final is coming, you can add a placeholder row and try different scores to see your final range.

Limitations & assumptions

This calculator assumes all items count as entered (no drops, curves, or policy quirks). If your syllabus drops the lowest quiz, simulate that by removing one quiz row. Extra credit can be modeled by adding points to earned or adding a small weighted category-ask your instructor which applies.
