Take-home by income
Same gross salary in both states — after federal tax, state income tax, and FICA. Advantage is take-home in Iowa minus Washington (single filer, standard deduction).
| Gross | Washington | Iowa | Advantage |
|---|---|---|---|
| $50,000 | $42,048 | $40,455 | −$1,593 |
| $75,000 | $61,131 | $58,743 | −$2,388 |
| $100,000Headline | $78,565 | $75,380 | −$3,185 |
| $150,000 | $112,869 | $108,091 | −$4,778 |
| $200,000 | $147,697 | $141,327 | −$6,370 |
At $100k: Washington keep ~$78,565; Iowa keep ~$75,380 (−$3,185). City COL can change equivalent salary even when state take-home is similar — use the scenario above for metro math.

Open salary calculatorWhy compare salary when moving from Washington to Iowa?
Cost of living and state income tax differ between Washington and Iowa. Here's how equivalent salary and after-tax comparison work, and how to use the relocation calculator for your move.
Equivalent salary and cost of living
When you move from Washington to Iowa, the same gross salary can buy more or less depending on cost of living (housing, goods, services). An equivalent salary is the amount you'd need in Iowa to maintain the same standard of living as in Washington. Our relocation salary calculator uses cost-of-living indices for major cities in both states and shows the equivalent salary and after-tax take-home so you can compare real purchasing power.
Washington has no state income tax; Iowa taxes income. Moving to Iowa typically means less take-home at the same gross. Use the calculator to see the exact difference for your salary.
State tax and after-tax take-home
State income tax varies: nine states have no state income tax (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, Wyoming), while others use flat or progressive rates. So moving from Washington to Iowa can change your after-tax take-home even at the same gross. The calculator applies federal tax plus each state's tax so you see take-home in both places. For a detailed tax breakdown by state, use our US Tax Calculator and select Washington or Iowa.
How to compare Washington and Iowa
State pages summarize the move; numbers come from choosing specific cities.
- Pick a city pair. Use a linked city route above (or open the main relocation calculator) so the tool knows which metros to use for cost of living and taxes.
- Enter gross annual salary and filing status. The calculator applies federal and state taxes for each city.
- Review equivalent salary and take-home. See how much gross you may need in Iowa for similar purchasing power and how take-home compares at the same gross.
- Optional: housing and other costs. Expand Housing, Commute, Lifestyle, and moving costs for a fuller picture.
When you open the calculator and choose specific cities, numbers are produced with the methodology below.
Cost-of-living index
Each city has a relative index where 100 is that country’s national average. A value of 120 means the modeled basket is about 20% more expensive than average; 85 means about 15% cheaper. US city indexes are rounded composites aligned with the C2ER Cost of Living Index (urban areas). Statewide tables elsewhere on the site use MERIC averages of those urban areas. Canada cities use Statistics Canada–style relative indexes. Neighborhood costs can still differ from the metro composite.
Equivalent gross salary (“same lifestyle”)
We scale your gross by the ratio of destination to origin COL: equivalent gross = your gross × (COL_destination ÷ COL_origin). That answers: “What gross in the new city matches the same broad spending basket as my current city?”—before taxes are applied again in the new jurisdiction.
Percent change vs your current gross
change % = ((equivalent gross − your gross) ÷ your gross) × 100. Positive means you need a higher gross in the destination to match the COL gap; negative means a lower gross can suffice.
After-tax take-home
Take-home is annual gross minus income and payroll taxes for the filing status you select. We use the same calculateTax engine as our paycheck and state calculators, with tax rules for 2026, each city’s state or province, and payroll taxes (US: Social Security and Medicare; Canada: CPP and EI). Where we model them, local wage or city income taxes are included. We do not model every possible deduction (for example voluntary 401(k) or RRSP deferrals); treat take-home as a planning estimate.
- Take-home in your current city — taxes your gross as if you live in the origin metro.
- Take-home in the new city at the same gross — same gross income, but tax rules for the destination state or province (and locality if modeled).
- Take-home in the new city at the equivalent gross — taxes the COL-adjusted equivalent salary in the destination.
“Approx. combined tax + payroll burden” (preview tables)
Shown as an effective rate: ((gross − take-home) ÷ gross) × 100, rounded to one decimal. It summarizes income plus payroll taxes on that row’s gross; it is not a marginal bracket rate.
Purchasing power line (example snapshot)
After we compute take-home in the origin at the scenario gross and take-home in the destination at the equivalent gross, we express the relative change as a percent: how much higher or lower the destination take-home is versus the origin take-home at those two points. Small differences are normal because tax schedules are not a perfect mirror of the COL ratio.
Housing snapshot (rent and % of income)
When shown, rent comes from our city-level housing benchmarks for the selected unit type (for example average rent for a 1-bedroom apartment). Rent as % of gross is (monthly rent × 12) ÷ annual gross × 100 using the scenario gross or equivalent gross as labeled in the table. Neighborhoods and exact units vary; use the full calculator to align with your housing choice.
All of the above is for education and planning. Your employer, deductions, credits, and local costs can differ—see our disclaimer on this page or consult a qualified professional for advice specific to your situation.
