Cost of Living Comparison Calculator
Estimate the salary you'd need in a new city to maintain your current standard of living. Use it when evaluating a job offer or relocation to understand true compensation differences.
About this calculator
Cost of living varies dramatically between cities and regions, so a salary that feels comfortable in one place may be inadequate in another. This calculator scales your current salary by the ratio of two cost-of-living indices — standardized scores that reflect average prices for housing, food, transport, healthcare, and other essentials. The formula is: Required Salary = Current Salary × (New Index / Current Index) × Adjustment, where the index ratio captures the raw cost difference and the Quality of Life Adjustment factor lets you apply a personal premium or discount (e.g., 1.1 if you require a 10% lifestyle upgrade, or 0.95 if you're willing to downsize). A result greater than your current salary means the new city is more expensive; a lower result means it's cheaper. Common index sources include Numbeo, ERI, and the Council for Community and Economic Research (C2ER).
How to use
Suppose you earn $70,000 in Austin (index 95) and are considering a move to New York City (index 187), with no lifestyle adjustment (factor = 1.0). Required Salary = 70,000 × (187 / 95) × 1.0 = 70,000 × 1.968 = $137,789. You'd need roughly $138,000 in New York to maintain the same purchasing power. If the job offer is $120,000, you'd effectively be taking a pay cut of about $18,000 in real terms — a critical insight before negotiating.
Frequently asked questions
What cost of living index should I use for the most accurate salary comparison?
The most widely cited sources are Numbeo (crowd-sourced, updated frequently, free), the C2ER Cost of Living Index (quarterly, survey-based, often used by HR departments), and the ERI Geographic Salary Differentials database (used by compensation professionals). For a quick comparison, Numbeo is convenient; for a salary negotiation or corporate relocation package, C2ER or ERI data carries more credibility. Make sure both your current and target city use indices from the same source, since indices are only comparable within the same dataset.
How does the quality of life adjustment factor work in this calculator?
The adjustment factor is a multiplier you set to reflect personal preferences beyond raw prices. A value of 1.0 means you want an equivalent lifestyle — no more, no less. Setting it to 1.1 means you want a 10% better lifestyle in the new city (perhaps a larger apartment or more dining out), which raises the required salary accordingly. A value of 0.9 means you're willing to live 10% more frugally, reducing the required salary. It's subjective by design — treat it as a sensitivity knob rather than a precise economic measure.
Why might a higher salary in a new city still leave me worse off financially?
High-cost cities often have significantly higher income and local taxes, which are not always captured in cost-of-living indices. State income tax, city tax, and higher property or rent prices can erode a seemingly generous salary increase quickly. Additionally, indices average across the whole city, but your specific neighborhood, commute costs, and childcare needs may differ substantially from the average. Always layer in a tax analysis and personal budget alongside this calculator's output before accepting a relocation offer.
