Understanding how a set of numbers relates to their combined total — budget categories, survey response counts, sales by region — is much clearer as percentages than as raw figures alone. This tool calculates each item's share of the total automatically.
Enter each label and value on its own line, and the tool sums the total, then shows every item's percentage share alongside its raw value, sorted from largest to smallest share.
This is useful for budget breakdowns, analyzing survey results, or any situation where you want to quickly see which items make up the biggest and smallest portions of a whole.

Frequently asked questions
Do the percentages always add up to exactly 100%?
Yes, since each percentage is calculated directly against the sum of all entered values, they always total 100% (accounting for minor rounding in the displayed decimal places).
Can I use negative values?
The calculation works with negative numbers mathematically, though percentage-of-total interpretations become less intuitive when the total or individual values are negative.
