DECISION READING
The threshold that changes the reading.
$115.6K is only a pre-tax floor. Because marginal tax and benefit deductions apply to the extra salary, a tax-aware break-even salary will generally be higher under the same spending assumptions.

Move the input and watch the boundary.
- Every $100 monthly cost change moves this pre-tax annual floor by $1,200.
- A city income tax or benefit-premium change raises the required gross salary further.
- A signing bonus should be separated from recurring salary.

- Reconciled the $4,233 starting room to case 04 and separately summed the $5,400 destination costs.
- Recomputed the $115,596 annual floor and $9,404 offer cushion from rounded monthly inputs.
- Verified that the result is consistently labelled pre-tax rather than a complete break-even salary.
BOUNDARIES
What the threshold does not decide.
- This shortcut does not solve the tax equation iteratively.
- It assumes the entered monthly costs remain stable.
- It is a negotiation screen, not career or financial advice.
