@macuser_22 I know you don't pay SE tax on $400 or less Net Profit but if you have more then don't you pay it on the whole amount? I think the 92.35% refers to something else.
You pay 15.3% SE tax on 92.35% of your Net Profit ( If it is greater than $400). The 15.3% self employed SE Tax is to pay both the employer part and employee part of Social Security and Medicare. So you get social security credit for it when you retire.
