How to calculate what you need on your final

The question every student asks at the end of term is "what do I need on my final to pass?" The maths is straightforward once you know your final exam's weight — the share of your overall grade it counts for. The formula is:

needed = (target − current × (1 − weight)) ÷ weight

Here weight is written as a decimal (a 30% final is 0.30). Suppose your current grade is 82%, you want 85% overall, and the final is worth 30%. Then needed = (85 − 82 × 0.70) ÷ 0.30 = (85 − 57.4) ÷ 0.30 = 92%. You would need 92% on the final.

What if I need more than 100%?

If the calculator returns a number above 100, your target can no longer be reached on the strength of the final exam alone. Your realistic options are to lower your target grade, ask about extra-credit opportunities, or speak with your instructor. The calculator flags this case in red so you are not caught out.

Weighted vs. unweighted grades

An unweighted grade treats every assignment equally. A weighted grade reflects that some components matter more: homework might count for 20%, the midterm 30% and the final 50%. To combine them, multiply each score by its weight, add the products, then divide by the total weight. The weighted grade calculator above does this automatically and normalises the weights for you.

How GPA is calculated

On the common US 4.0 scale, each letter grade maps to grade points (A = 4.0, B = 3.0, and so on). Your GPA is the credit-weighted average: multiply each course's grade points by its credit hours, sum those, and divide by total credits.
