A weighted grade is the weighted average of your category scores: multiply each category’s percentage by its weight, add all those products, then divide by the sum of the weights. For example, homework 20% scored 90, exams 80% scored 85 gives (20 × 90 + 80 × 85) ÷ 100 = 86%. AnyTool Grade Calculator does this live, divides by the actual total weight so it stays correct even if your weights don’t add to 100, and warns you when they don’t.

To find the score you need on a final exam, enter your current overall grade, the final’s weight as a percentage of the course, and your target grade. The required score is (target − current × (1 − w)) ÷ w, where w is the final weight as a decimal. For example, with a 70% current grade, an 80% target and a 50%-weighted final you need 90% on the final. AnyTool Grade Calculator flags when the target is already secured (needed ≤ 0) or impossible without extra credit (needed > 100).

A percentage is mapped to a letter and a 4.0-scale GPA point by a threshold table. A common US +/− scale puts 93–96% at A (4.0), 90–92% at A− (3.7), 87–89% at B+ (3.3), and so on down to F below 60%. AnyTool shows your letter and GPA point for every result, but the thresholds are configurable because grading scales — and rounding policies like 89.5 → A− — differ by school, department and instructor.

AnyTool Grade Calculator is completely free with no account or limits, and all three modes — weighted, points and final-needed — are computed by a small, unit-tested engine that runs entirely in your browser, so the grades you type are never sent to a server. The page works offline after first load and uploads nothing.
