What does this tool do?

Extra Credit Grade Calculator computes the result directly in your browser — Wondering if that extra credit is worth it? This shows exactly how added points change your percentage and letter grade. Nothing you enter is uploaded or stored.

Points earned (your current total points)

Total points possible (points)

Extra credit points (adds to earned AND total)

How extra credit works: bonus points add to your earned total AND to the total possible, so the math is (earned + extra) ÷ (total + extra). Why it moves less as you go: the higher your current percentage, the less any fixed extra credit moves it — this tool shows the real point change. Letter scale: 90/80/70/60 A/B/C/D/F is the common example; your course may differ. Ask first: confirm your teacher counts extra credit this way before relying on the number.

How this calculator works

Weighted grade with extra credit: final = current grade + (extra credit points x weight adjustment). The tool handles whether extra credit can exceed 100%.

Worked example

An 82% grade with 5 points of extra credit on a 100-point final-weighted scale lands at about 84-87% depending on the category weighting.

Extra credit math: points converted through category weights to a final grade — Extra credit helps most when applied to heavily weighted categories; check your syllabus weights.

FAQ

How much will extra credit raise my grade?

It depends on your current score and how much total the class has. The change is roughly the extra points ÷ (total + extra) in percentage terms — use the tool with your real numbers.

Does extra credit help a low grade more?

Yes — extra credit moves your percentage more when your total is small or your grade is low. It's a smaller percentage-point shift at the top of the scale.

Is extra credit worth the effort?

If you're on a letter-grade boundary (e.g., 79.4% vs 80%), even a small bump crosses the line. If you're far from a boundary, focus effort on real assignments instead.
