How a job offer becomes a monthly relocation comparison.

The calculator compares the current salary with the proposed salary as annual gross employment income. It does not assume that bonuses, equity, commissions, overtime, or signing incentives recur unless a user deliberately includes them in the salary input.

For a clean comparison, use the recurring base salary on both sides. One-time relocation payments and moving expenses should be recorded separately because spreading them across every future month can make a weak offer look stronger than it is.

The model estimates federal income tax using the configured tax-year brackets and standard deduction, adds employee Social Security and Medicare, and applies a modeled state-income-tax treatment. It converts the estimated annual after-tax amount to a monthly figure.

This is not a payroll calculator or tax return. Local and city income taxes, itemized deductions, tax credits, pre-tax retirement contributions, health benefits, stock compensation, self-employment income, and household-specific rules can create a meaningful difference.

The most decision-relevant comparison subtracts the housing and recurring monthly spending you expect in each location. Use a realistic rent or mortgage estimate rather than a metro median when you have one. Include commuting, utilities, insurance, parking, and other recurring costs only when you can estimate them consistently on both sides.

Census rent and regional cost context are screening benchmarks. They help identify assumptions that look unusually high or low, but they are not live apartment quotes and do not prove that a suitable home is available.

The break-even salary is the target gross salary that produces approximately the same modeled monthly room as the current scenario after the selected taxes, housing, and spending. The solver changes the target salary until the two monthly outcomes converge within the product tolerance.

A break-even result is sensitive to every input. It should be read as a negotiation threshold under the current assumptions, not as the market value of a role or a guarantee of equivalent quality of life.

Run a base case, a conservative case, and an optimistic case. Raise target rent, add a commute or insurance increase, and remove uncertain compensation in the conservative case. If the decision changes under a small adjustment, the useful conclusion is that the offer has little margin.

Do not use the calculator as financial, tax, legal, investment, immigration, or employment advice. Verify payroll, benefits, local taxes, housing availability, and contract terms with qualified sources before committing to a move.
