Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Weighted percentage model; no letter-grade thresholds, dropped work or extra credit. Current average must exclude the final.
Example Calculation
- Current average excluding final: 80 %
- Final exam weight: 25 %
- Target course grade: 85 %
An 80% current average and 25%-weighted final require 100% on the final to finish at 85%.
Frequently asked questions
How do I use this calculator?
Enter current average excluding final, final exam weight, target course grade. The result updates automatically. Use Reset to restore the example values.
What method does it use?
required=(target−current(1−weight))/weight.. Weighted percentage model; no letter-grade thresholds, dropped work or extra credit. Current average must exclude the final.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
