undercalculate
Guess too low
To undercalculate is to estimate too low—to arrive at a figure smaller than reality warrants.
You might undercalculate expenses on a project, leaving yourself short of funds, or undercalculate the time needed for a task: We undercalculated how long the renovation would take by about three months.
