As I begin my search I was hoping someone can validate how to think about target SDE. My understand in simplest terms is $1M in SDE, assume 50% goes towards debt servicing (SBA Loan), the remaining 50% goes towards owners salary, reinvestment, building cash reserves, and taxes.

Let’s say my cost of living is $200k. As a former W2 employee that would mean roughly $280k minus fed, state, health, ssi etc to get to $200k.

Does it work the same way with SDE that I should assume my true requirements are $280k in this model and that would mean only $220k left over for reinvestment, tax, reserves? If so is that realistic/healthy
In terms of what is leftover for the business?

Any feedback on this will be much appreciated. Thank you
