Calculate GPA

Final Grade Calculator — what do I need on the final?

Enter your current grade, how much of the course is already decided, the final's weight and the grade you want. The calculator solves for the exact exam score you need — and tells you plainly if that target is out of reach, and what the best possible outcome is.

Formula: needed = (target × 100 − current × completed weight) ÷ final weight. Calculated locally; nothing is stored.

Worked example

The starting numbers tell a common story. At 86% with 70% of the course graded, a 30% final and a 90% target: needed = (90 × 100 − 86 × 70) ÷ 30 = 99.3% — technically alive, practically a near-perfect paper. Drop the target to 88% and the requirement falls to 92.7%. Knowing which side of that line you sit on, weeks before the exam, is the entire point: it decides whether you grind for the A or protect the B+ and spend the hours elsewhere.

After the final

Once the grade lands, fold the course into your term with the semester GPA calculator, or see the effect on your record with the cumulative calculator.

Final grade questions

How do I calculate what I need on the final?

Needed score = (target × 100 − current grade × completed weight) ÷ final weight, with all weights in percent. Sitting at 86% with 70% of the course graded and a 30% final, an A target of 90% needs (9000 − 6020) ÷ 30 = 99.3% — steep. A target of 88% needs 92.7%.

What if the number comes out above 100%?

Then the target is mathematically out of reach this term, even with a perfect exam. The calculator shows the best course grade still achievable so you can re-aim at a realistic target instead of finding out afterwards.

What if I don't know the final's weight?

Check your syllabus — weights are almost always listed there. If the final replaces a lower midterm or is curved, the simple formula is an estimate; treat the verdict as a planning guide, not a guarantee.

Should the completed weight and final weight add to 100?

Ideally yes: completed weight is everything already graded, final weight is the exam (plus anything else still outstanding, if you treat it as one block). If they add to less than 100, the missing part is other ungraded work — fold it into the final weight for a conservative estimate.
