Grade Calculator

Calculates current weighted average from completed items, target grade, remaining weight. Defaults are filled in so you can review a working example before changing inputs.

Enter one completed score per line as score, weight.

%

Desired overall course percentage.

Weight of the remaining assignment or final exam in the same units as the completed item weights.

  • Scores are percentages from 0 to 100.
  • Weights may be percentages or any proportional units if completed and remaining weights use the same unit.
  • The MVP models one remaining graded item.
  • Curves, dropped grades, extra credit, and school-specific gradebook rules are excluded.

What the result means

Current weighted average answers the page's main grade question. Weighted average across completed items only. Read the score or GPA estimate first, then compare weights, credits, and grading-scale assumptions. Use needed score, completed weight, and total modeled weight to explain why current weighted average moved when an input changed. Compare the estimate with the syllabus or official school policy before treating it as final.

Total modeled weightCompleted weight plus remaining weight.

Use the result this way

  1. Start with Current weighted average, then use supporting outputs only to explain the primary answer.
  2. Verify completed items, target grade, and remaining weight before copying the result.
  3. Keep units consistent with the labels shown in the form, check separators in pasted text so every value is parsed as intended, and stay within the documented minimum and maximum ranges.
  4. Compare the estimate with the syllabus or official school policy before treating it as final.

User job

How to use this calculator

Use Grade Calculator when you need current weighted average, then use needed score and completed weight to check the context for grade planning, GPA review, course-score checks, and school-policy comparison.

Best for

  • Estimating grade outcomes
  • Testing how credits, weights, or scores affect the result
  • Reviewing a default example before entering your own completed items and target grade.

Check before relying

  • Compare the result with the official grading policy before treating it as final.
  • Scores are percentages from 0 to 100.
  • Weights may be percentages or any proportional units if completed and remaining weights use the same unit.
  • Source context: OpenStax, reviewed 2026-05-26.

Formula

Use weighted mean for completed scores, then rearrange the weighted mean equation to solve for one remaining score. Key assumptions: Scores are percentages from 0 to 100. Weights may be percentages or any proportional units if completed and remaining weights use the same unit. The MVP models one remaining graded item.

Inputs

Enter completed items, target grade, and remaining weight for grade planning, GPA review, and school-policy comparison. Before calculating, keep units consistent with the labels shown in the form, check separators in pasted text so every value is parsed as intended, and stay within the documented minimum and maximum ranges. Completed items: Enter one completed score per line as score, weight. Target grade: Desired overall course percentage. Remaining weight: Weight of the remaining assignment or final exam in the same units as the completed item weights.

Example

Using the default inputs, Grade Calculator returns current weighted average of 85.714286%. Adjust completed items, target grade, and remaining weight to match your own scenario.

FAQ

How is current weighted average calculated here?

Use weighted mean for completed scores, then rearrange the weighted mean equation to solve for one remaining score. The first assumption to check is: Scores are percentages from 0 to 100.

What does Current weighted average mean for grade?

Read the score or GPA estimate first, then compare weights, credits, and grading-scale assumptions. Secondary values such as needed score, completed weight, and total modeled weight are there to explain the primary answer, not to replace it.

What should I enter for Completed items?

Enter one completed score per line as score, weight. Keep units consistent with the labels shown in the form, check separators in pasted text so every value is parsed as intended, and stay within the documented minimum and maximum ranges.

How does Target grade change current weighted average?

Desired overall course percentage. Changing it can alter current weighted average because the formula uses the submitted inputs together. Also compare grade scale, credit weight, remaining assignments, dropped scores, pass/fail rules, and rounding policy.

Why does the grade example show 85.714286% for current weighted average?

The default inputs produce 85.714286% for current weighted average. Treat that as a format and scale check, then replace every default value with your own inputs.

Should I use the grade result as an official school record?

No. Use it for planning and compare it with the syllabus, grading scale, credit policy, and any school-specific rounding rule.
