Final Grade Calculator

A free final grade calculator that answers the end-of-semester question directly: given the grade you have now, the grade you want, and how much the final exam counts, what do you have to score? The math is one rearranged weighted average — needed score = (target − current × (1 − weight)) ÷ weight — and the calculator reports the result honestly, including needed scores above 100% when the target is simply not reachable with the final alone. Two companion views compute a weighted course grade from category scores and convert a test's points into a percentage and letter grade. Everything is calculated in your browser on the numbers you enter; nothing is uploaded or stored. It is weighted-average arithmetic, not academic advice — category weights, drop-lowest rules, rounding, and letter cutoffs all vary by instructor, so confirm the details against your own syllabus.
