@flatKansas in the vast majority of cases, the net price calculators are not accurate for divorced, and remarried parents. The exception would be IF the NPC specifically asks separately about incomes for divorced and remarried parents. Most NPCs do not ask these questions.
This is especially true of Profile schools and most especially for those that use everyone’s income students inntheir calculations.
You make an excellent point…so what happens if the amount this non-custodial parent needs to contribute exceeds what his divorce decree says? Will he pay more? Will the other parent?
