miscalculating
Getting figures wrong
Miscalculating is making an error in calculation or judgment.
The word applies to mathematical mistakes but more often to misjudging situations: He's miscalculating if he thinks they'll back down.
Someone miscalculating badly enough faces serious consequences—a contractor miscalculating costs, a general miscalculating enemy strength.
