About Grade Calculator

Computes a weighted course grade from individual assignments, maps the result to a standard letter grade (A+ through F) and 4.0-scale GPA, and includes a final exam predictor. Enter each assignment’s score, max score, and weight percentage. The tool tracks total weight used and warns when it doesn’t sum to 100%. The final exam calculator takes your current weighted average and tells you exactly what score you need on the final to hit a target grade.

• Weighted average: each assignment’s percentage × its weight, summed and normalized
• Standard 13-tier grading scale from A+ (97%+, 4.0) through F (0%+, 0.0)
• Final exam predictor: (desired_grade × 100 - current_weighted × 100) / final_weight
• Tracks total weight used and displays remaining unallocated weight

Frequently Asked Questions

What if my school uses a different grading scale?

The tool uses a fixed 13-tier US standard scale. Custom scales aren’t supported—the weighted percentage is still accurate, but you’ll need to map the letter grade manually if your institution differs.

Why does the final exam calculator say I need more than 100%?

Your current weighted average is too low for the target grade given the final’s weight. Either lower your target or check if extra credit is available.
