Cost of Living FAQ
How city costs are calculated, where the data comes from, and how to read your results.
How is cost of living calculated by city?
We use a relative index for rent, groceries, dining out, transport, and utilities, benchmarked against New York City = 100. A city with a rent index of 50 is roughly half as expensive to rent in as New York.
What does purchasing power adjusted mean?
It answers: if you earn a given salary in City A, what salary would you need in City B to afford the same lifestyle? We calculate this from the ratio of each city's overall cost index.
Where does the underlying data come from?
Our figures are representative estimates compiled from public cost-of-living reports and periodically reviewed. They are meant for quick, directional comparisons rather than exact pricing — see our methodology page for more detail.
How often is the data updated?
We review and refresh the dataset periodically as living costs shift. Because figures are estimates, always confirm current local pricing before making a major financial decision.
Can I share my comparison results?
Yes — every tool has a Copy Shareable Link button that encodes your inputs into the URL, so anyone who opens the link sees the same comparison instantly.
Are the tax and salary calculators official financial advice?
No. Our tax, take-home pay, and retirement calculators use simplified, disclosed formulas for illustrative planning only — they are not a substitute for a tax professional or financial advisor.
