Monthly pay in Illinois: the biggest check, the longest gap

Monthly pay runs on just 12 periods a year — the fewest of any schedule this site supports — so each check is the largest single deposit you'll see. On a $75,000 salary in Illinois, this engine estimates $4,835.40 net once a month, compared with $2,231.72 roughly every two weeks under biweekly pay; the annual total is the same, but monthly pay asks you to budget across a longer stretch between deposits.

A single missed or delayed monthly paycheck has more cash-flow impact than a missed biweekly one, since it represents a full month of expenses rather than two weeks — worth weighing if your Illinois employer offers a choice of pay schedule.
