Tool Percentage Recalculator — Calculate and normalize multiple percentages to sum to 100%, with the option to exclude specific values from the recalculation. Enter up to four percentage values and check the "Ignore this" box next to any percentages you want to exclude; the tool will automatically recalculate the remaining percentages proportionally so they add up to 100%.
