What this result does not account for
- Single remaining-weight block, not per-assignment
- Current grade assumed weight-faithful
In short: Banked work is current grade × completed weight. An 84 across 70% of the course banks 58.8 points, leaving 31.2 to find; chasing a 90 means the remaining 30% must average 104.000000% — beyond a perfect score, and the page says so instead of lying. Target 88 and the need drops to 97.333333%: possible, with no margin. The remaining weight is the only part of a course still for sale — this is the arithmetic of knowing exactly what it costs.
Formula
needed = (target − current × done%) ÷ (100% − done%)
Grades are weighted averages: your current grade covers only the fraction of the course already graded. Bank those points first (current × done%), subtract from the target, and the difference must come from the remaining weight — whatever fraction of the course is still ungraded. If the required average on that remainder exceeds 100, the target is arithmetically closed and no study plan changes it; if it sits in the 90s, the target is live but every remaining assignment is final-exam stakes.
Worked Example
- Enter your current average and the graded weight.
- Enter the course target.
- Read the banked points and the gap.
- Check whether the needed average is even possible.
Defaults: 84 current, 70% done, 88 target → 58.8 banked, needed 97.333333% — live, zero margin. Raise the target to 90 and the same arithmetic closes the door: 104.000000%, beyond a perfect score. The classic 'what do I need on the final' is this division when the final is the only thing left.

Methodology & Editorial Standards
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.
This engine was reconciled against an independent reference implementation and hand-verified for the worked example above before release. Our full five-stage review process is published on the About Us page.

Assignment Weight Calculator — 8 Expert FAQs
8 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
How do I calculate what I need on the final?
Bank your current work (current grade × completed weight), subtract from the target, and divide by the remaining weight fraction. An 84 through 70% of the course chasing 90 needs 104.000000% on the rest — closed. Chasing 88 needs 97.333333%. The formula is the whole answer; every 'grade needed' calculator is this division.
What does 'assignment weight' actually mean?
The fraction of the course grade each piece carries — a final at 30% weighs three times a quiz at 10%. Weights make an 84 in a heavy course different from an 84 in a light one: what matters is how much graded work stands behind the average and how much weight remains in front of it.
Why does the calculator refuse my completed weight of 100?
Because nothing remains to influence — the course is fully graded and the target is whatever it is. The math divides by the remaining weight, so 0% remaining is meaningless and 100% completed is a transcript question, not a planning one. Keep the completed share strictly between 0 and 100.
My needed average is over 100. Is it hopeless?
Arithmetically yes — a perfect score on everything remaining still falls short, and the honest move is revising the target (a B+ threshold may be live) or asking the instructor about extra credit, which changes the weights themselves. What the page refuses to do is print a study plan for an impossible number.
Can the needed average be negative?
Yes — when banked points already exceed the target. Then the remaining work is formality for the target (though not for learning, and not for other targets). The page prints that door too: the target is already secured by the banked fraction.
Does extra credit fit this model?
Only if it changes the weights. Extra credit that adds points inside the remaining 30% raises the ceiling above 100 for that slice; credit added to the banked portion lifts the current grade before the arithmetic runs. Estimate it as a current-grade bump and the tool stays honest.
Why do schools weight assignments at all?
Because a semester project and a homework sheet are not the same evidence. Weighting says the final exam demonstrates more than a Tuesday quiz — and it concentrates stakes: in a course with a 30% final, nearly a third of the grade is decided in three hours. This page exists so those stakes are computed, not feared.
How is this different from the final grade calculator?
That page computes the course grade from completed scores and weights; this one inverts the question — given a target, what must the ungraded remainder average? One reads the past, the other prices the future. Together they cover both directions of the same weighted-average algebra.
