Weighted grade calculator for any course
This grade calculator handles the two questions every student asks: what's my grade right now, and what do I need on the final? Add each assessment with its score and syllabus weight, and the weighted average appears live. Then set a target grade and the final exam's weight to see exactly the score you need — including the honest news when a target is out of reach.
Why weighted averages trip people up
A 95 on homework worth 10% moves your grade far less than an 80 on a midterm worth 35% — simple averaging of scores gets this badly wrong. The calculator multiplies each score by its weight before averaging, the same way your instructor's gradebook does, and it works mid-semester even when the weights entered so far don't total 100%.
Plan your finals week
Knowing you need a 72 — not a vague “do well” — changes how you allocate study time across courses. Run each class through the tool and put the hours where the required score is highest. For semester-level math, the GPA calculator converts course grades into a credit-weighted GPA, and the percentage calculator handles quick score conversions.
Frequently Asked Questions
How is a weighted grade calculated?
Multiply each score by its weight, add them up, and divide by the total weight. If homework (20%) is 92 and the midterm (30%) is 78, the weighted grade so far is (92×20 + 78×30) ÷ 50 = 83.6%.
How do I find what I need on the final exam?
Needed = (target − current × (1 − w)) ÷ w, where w is the final's weight as a decimal. The tool computes it for you and warns when the target needs more than 100% — i.e., it isn't reachable.
Do my weights have to add up to 100%?
No. The current-grade figure uses only the weights you've entered, which is exactly how a grade 'so far' works mid-semester. The final-exam section then treats the remaining weight correctly.
Can I use points instead of percentages?
Convert each assignment to a percentage first (points earned ÷ points possible × 100), then enter those. The weighting math is identical afterwards.
What if the calculator says I need more than 100%?
It means the target grade is mathematically out of reach with the final's weight — every remaining point can't close the gap. Aim for the best reachable grade instead, or check if extra credit is available.
