How this calculator works
Core formula
percent of, percent share, or percentage change depending on modeThe calculator switches between three common percentage formulas: finding a share of a number, finding what percent one value is of another, and measuring change from one value to another.
- Percentage change uses the first value as the base.
- Formatted output adds percent signs only when the mode requires it.

FAQ
Key questions answered
What numbers should I enter?
Enter the completed amount first and the total amount second so the percentage reflects real progress.
Does this calculate progress as part of a whole?
Yes. It is built to answer the common question of how much has been completed out of the full total.
What if completion is over 100%?
That usually means the completed amount is greater than the original target, which can happen when you exceed a goal.
What if the total amount is zero?
A zero total does not produce a meaningful completion percentage, so you should check the input before relying on the answer.
Can I use it for tasks, sales goals, or courses?
Yes. It works for any situation where one amount is part of a larger total.
Is this different from percentage change?
Yes. Completion measures part versus total, while percentage change compares an old value with a new one.
Why is completion percentage useful?
It gives a simple progress signal that is easier to communicate than raw counts alone.
