Assumptions

Two levers. The tax rate is an effective all-in assumption, not your top bracket. The savings target is the share of take-home pay you want going to the future, not the baseline.

How to read this: The baseline is what your household spends to exist for a month, before anything goes to the future. Gross income needed works backward from it: enough pre-tax income that, after the tax assumption comes out and your savings target is set aside, the baseline is still covered. Your real tax picture depends on your situation, so treat the tax input as a rough assumption and adjust it. Most households have never written this number down. It is worth ten minutes to know it, because every income decision, every move, and every job change gets measured against it.

Now put the number to work.

The baseline is a snapshot. The budget is the rhythm.

Knowing the number is step one. Deciding what every dollar does before the month begins is the habit. The Budget App is $24 one-time access, no bank link, family 50/30/20.
