LIVE MOVE REPLAY · SEPTEMBER 7, 2026
Dallas to Seattle: why a $25,000 raise still lost monthly room
We entered this single-filer scenario into the public MOVE calculator: Dallas salary $100,000, Seattle offer $125,000, rents $2,100 and $3,200, and Dallas non-housing spending $2,000. The live screen returned −$145 monthly room, a $127,549 break-even salary and −$5,227 over three years. These are observed model results with hypothetical household inputs, not a real employee's finances.
| Layer | Dallas | Seattle |
|---|---|---|
| Federal income tax / year | $13,170.00 | $18,734.00 |
| Employee FICA / year | $7,650.00 | $9,562.50 |
| State wage income tax in this model | $0 | $0 |
| Monthly take-home estimate | $6,598.33 | $8,058.63 |
| Rent assumption | $2,100 | $3,200 |
| Non-housing spending | $2,000 input | $2,505.49 model estimate |
| Monthly room | $2,498.33 | $2,353.13 |
The cost multiplier is a model assumption
MOVE's configured cost indices are 91 for Dallas and 114 for Seattle. The ratio 114 ÷ 91 scales $2,000 to $2,505.49. Those numbers are product assumptions; they are not asserted to be current BLS or BEA observations for these cities. With tax and rent unchanged, replacing that estimate with a household budget of $2,200 reverses the result to approximately +$160 per month. A user should verify the spending basket before accepting the score.
Salaries stay at $100,000 and $125,000; single filing status, Dallas rent $2,100 and Dallas other spending $2,000. The $6,000 moving cost is an added assumption, outside the live snapshot.
| Monthly room difference | -$145 |
|---|---|
| Maximum rent to preserve Dallas monthly room | $3,055 |
| First-year difference, after moving cost | -$7,742 |
| Five-year difference, after moving cost | -$14,712 |
| Moving-cost payback | No payback at this monthly result |
This scenario reduces monthly room. -$145 per month before omitted household costs.
One- and five-year totals hold salary, rent, spending and the tax calculation constant. They are arithmetic scenarios with no wage growth, inflation, investment return or future tax-law forecast. This reproduction includes federal income tax and employee FICA; it excludes benefits, Washington payroll premiums, local taxes and credits.
Turn the sign change into a concrete decision
At the recorded spending estimate, rent would have to fall to about $3,054.80 to preserve the Dallas monthly room. A $6,000 move has no payback when the monthly difference stays negative. Even in the $2,200 spending alternative, recovering $6,000 takes roughly 37 months. A small positive salary comparison can therefore remain unattractive for a short stay.
Reproduce the listed inputs in MOVE. This page deliberately exposes the regional spending assumption, while the payroll note explains the tax ceiling. Confirm benefits, Washington payroll premiums, local taxes and other omissions with the employer before relying on a household budget. No payment or account is needed for this analysis.

The narrow conclusion supported here.
The federal layer alone reduces the headline $2,083 monthly raise to about $1,620. The replay above then includes employee FICA, rent and the declared spending estimate, leaving about −$145 monthly room. Benefits, Washington payroll premiums, local taxes and other omitted household costs still require separate verification.
SENSITIVITY
Change one input before trusting the result.
- Different filing status changes both the deduction and bracket thresholds.
- Pre-tax benefits and retirement contributions can change taxable wages.
- The $125K case crosses into the 24% bracket only for income above its threshold; it is not taxed entirely at 24%.

BOUNDARIES
Stop where the evidence stops.
- This simplified liability excludes credits, itemization, AMT, and special income.
- The federal-tax walkthrough isolates income tax; the extended replay above also includes employee FICA. It assumes no state wage income tax for Dallas or Seattle and excludes Washington payroll premiums and local taxes.
- It is an estimate, not a tax return or advice.

- Applied each marginal bracket separately rather than using the top rate on all income.
- Recomputed both liabilities and the incremental-tax difference.
- Reconciled employee FICA, monthly take-home, rent and the spending assumption against the observed MOVE output; identified Washington payroll premiums, benefits and local taxes as omissions.
