If the garnishment deduction is calculated as a percentage of your earnings, a deduction will occur each pay period, up to the maximum deduction allowed based on federal and state regulations. For example, if your garnishment deduction is 25 percent of your pay, that amount will be deducted each payday.
If the garnishment deduction is a fixed amount, the amount will be recalculated to a biweekly amount. That calculation is then divided into two payments. For example, a monthly $250 garnishment payment will become $125, deducted during each biweekly paycheck.
