What Does Your Salary Actually Buy in a New City?

A cost of living calculator compares the price level of one city with another so you can estimate how far your salary will go after a move. It usually blends housing, groceries, transportation, healthcare, utilities, and other day-to-day categories into one index, then converts that difference into an equivalent salary number. The goal is not just to compare prices, but to compare purchasing power between two places.

Cost of living is usually calculated as a weighted index that combines several recurring household expenses, with housing carrying the heaviest influence. A calculator starts with category-level price assumptions, applies city-specific index values, and then blends those into an overall cost of living comparison. National average is typically set to 100, which means values above 100 are more expensive than average and values below 100 are less expensive.

The equivalent salary formula is current salary multiplied by the target city index divided by the current city index. If the target city is cheaper, the required salary falls. If the target city is more expensive, the required salary rises. This approach gives you a quick purchasing-power estimate before taxes, and it is especially useful when evaluating relocation offers, remote-work negotiations, or a move to a no-income-tax state.

The highest-cost U.S. cities are usually Manhattan, San Francisco, Honolulu, Boston, and Washington, DC, with Seattle and Los Angeles not far behind. In these markets, housing drives the largest gap versus the national average, but transportation, dining, and utilities can also push the total cost higher. That is why a high nominal salary does not always translate into stronger day-to-day buying power.

Seven states have no state income tax on wage income: Alaska, Florida, Nevada, South Dakota, Texas, Washington, and Wyoming. New Hampshire and Tennessee also do not tax ordinary wage income, although they have had different treatment for investment income in past years. A move into one of these states can improve net pay, but you still need to compare rent, transportation, and insurance costs because the total lifestyle equation can still vary sharply.

Austin is roughly 34% cheaper than San Francisco in the default example used on this page. A salary of about $95,000 in San Francisco maps to an equivalent salary of roughly $62,600 in Austin using the overall city index comparison. Housing is the biggest driver of that gap, because Austin rents and home prices sit far below San Francisco even though groceries, utilities, and transportation are not proportionally as low.

Cost of living is not the same as inflation. Inflation measures how quickly prices are changing over time, while cost of living measures the absolute price level in a specific city or region at a point in time. You can have a city with a high cost of living and low short-term inflation, or a lower-cost city experiencing faster price growth. For relocation decisions, the absolute price level usually matters more than the recent rate of change.

Major cost of living datasets are usually refreshed on an annual or quarterly cycle, depending on the source and the category. Housing can move faster than healthcare or education, so any city comparison should be treated as an estimate rather than a final budget. This calculator uses a hardcoded 2025 city index set so results are fast and static, but you should still cross-check neighborhoods, rent listings, and tax details before relocating.
