In FL does one pay child support monthly?

Child support is based on a monthly guideline calculation,  but it can be paid weekly or biweekly or bi monthly depending on the payors pay period.  It wont change the amount if it is paid monthly, weekly or bi weekly.  There is a standard formula to calculate the payment. For example if you are paid biweekly  then you multiply the monthly amount by 12 then divide by 26 to arrive at a biweekly. If you want to pay weekly, then you multiply the monthly by 12 and divide by 52.  If you are paid bi monthly (twice a month) then you can simply divide the monthly amount by 2.   What you cannot do is calculate a biweekly payment by dividing the monthly payment by 2, and you cannot calculate a weekly payment simply by dividing the monthly by 4 as that ignores the fact that some months have 5 weeks.
