Grade Calculator
Calculate the score needed on one remaining weighted assessment to reach an entered target course grade.
One remaining weighted assessment
Enter percentages as complete ASCII decimals. The assessment weight is converted from percent to a 0-1 fraction before applying the formula.
Required assessment score
Enter the three required percentages and calculate. No result or copy payload exists yet.
Formula and worked example
Weight fraction = remaining assessment weight / 100. Required score = (target grade - current grade x (1 - weight fraction)) / weight fraction.
For an 80% current grade, 85% target, and 25% remaining weight: the weight fraction is 0.25, completed fraction is 0.75, current contribution is 60, required contribution is 25, and 25 / 0.25 = 100% required on final.
No intermediate value is rounded.
Assumptions and limitations
The formula assumes the current grade represents all completed work and that one remaining assessment has exactly the entered course weight.
Extra credit, category weighting, dropped assignments, curves, minimum-exam rules, penalties, and institution-specific grading policies are not modeled. The result is an arithmetic planning estimate, not a guaranteed final grade.
Use the GPA Calculator to project one term, or the CGPA Calculator to aggregate completed terms.

Accuracy and limitations
Calzivo tools are built for practical estimates, conversions, and checks. Some tools use standard formulas or simplified assumptions, and results can be affected by input accuracy, rounding, units, local rules, or changing official requirements.
Education results depend on the scale and grading rules you enter. Schools and institutions may use different official policies, so confirm important results with your syllabus or records office.

Frequently Asked Questions
Common questions about Grade Calculator and how to read the result.
Why can the result exceed 100%?
The target is not reachable through that assessment alone under the entered weighted-average model. Extra credit or a different course policy is not assumed.
Why can the result be below zero?
The completed-work contribution already secures the target under the entered model. The exact algebraic result remains visible.
Does this include dropped assignments or category weights?
No. It models one current grade, one target grade, and one remaining assessment weight.
Is the result guaranteed?
No. It is an arithmetic planning estimate and does not replace the syllabus, gradebook, or instructor policy.
