According to another post on this thread, Ramsey says 10 percent of your after-tax income. ?
Trying to remember from Financial Peace University but think it was left up to the individual but Dave pays tithing on “the bigger number just in case”.
PS I’m Mormon but could never get myself to tithe until going through Financial Peace University.
Actually I don’t remember now whether it was Ramsey, or the sometimes controversial Christian psychiatrist Dr. Meier. Some might actually have legalistic rules about it. And some might follow on to Old Testament illustrations such as “first fruits” and want it to be done before taxes. But if giving based on personal profits is meant (i.e. as if you sold goods for which you paid $9 for $10 and kept $1, which is your profit), after tax is as good as any a reference point. Since deducting it will increase your after tax income, you might have to do some algebraic calculations if you really want it to be exactly 10% or X%. I say why not just donate a tithe on your resulting tax refund and call it a wash.
