Does this mean there are fifty different ways of calculating support?

It may appear this way at first glance, but for the most part there are three basic child support formulas (with some variations for each state). This DOES mean that calculating a support obligation from state to state will produce a different support obligation amount. The difference in amounts from state to state can be very significant, because of the difference in average household income that each state takes into consideration. Also keep in mind that certain states calculate the child support obligation on a weekly, monthly, and annual basis.
