Cost of Living Calculator — what salary you'd need in another city

The cost of living calculator answers a specific, practical question: if you moved from your current city to a new one, what salary would you need to maintain the same standard of living? It's not a tax tool, and it's not a budgeting tool — it's a salary equivalency tool built around a single cost-of-living index comparison, with a special focus on the one category that usually drives almost the entire gap between cities: housing.

Arb Digital built this for job offers that come with relocation, for remote workers weighing a move to a cheaper or more expensive metro, and for anyone who's seen a "cost of living is 40% higher there" headline and wanted to know what that actually means for their paycheck rather than just their gut reaction.

What This Cost of Living Calculator Does

You enter your current annual salary, a cost-of-living index for your current city (100 represents the national average), and a cost-of-living index for the target city you're considering. The calculator multiplies your salary by the ratio of the target index to the current index, producing the salary you'd need in the new city to have equivalent purchasing power. You can also adjust the housing weight — the share of a typical cost-of-living index attributable to housing — to see how much of the total gap between the two cities is being driven by housing costs specifically, versus food, transportation, healthcare, and everything else combined.

The results grid breaks the comparison into four pieces: the dollar difference between your current salary and the equivalent salary, the percentage change in cost between the two cities, the housing-driven share of that gap in dollars, and the purchasing power your current salary would actually have if you moved to the target city without any raise at all.

How to Use It

1. Enter your current annual salary. Use your gross salary, since cost-of-living indices are typically built around pre-tax income comparisons.
2. Enter your current city's cost index. If you're not sure, 100 is a reasonable default representing the US national average.
3. Enter the target city's cost index. Cost-of-living index tools and city-data sites publish these regularly; a value of 140 means a city is roughly 40% more expensive than the national average.
4. Adjust the housing weight if you want more precision. The default of 30% reflects typical household budget shares, but you can raise or lower it based on your own spending pattern.
5. Compare the equivalent salary to any offer you've received. If the offer is below the calculated number, the "raise" may not actually improve your financial position.

The Formula — A Simple Ratio With a Housing Lens

The core equation is straightforward: equivalent salary equals your current salary multiplied by the target city's index divided by your current city's index. If your salary is $75,000, your current city index is 100, and your target city index is 140, the equivalent salary is $75,000 × (140 ÷ 100) = $105,000 — that's what you'd need to earn in the new city to match your current purchasing power. The Bureau of Labor Statistics' Regional Price Parities program is a genuine, authoritative source for how relative price levels vary by metro area across the US, and is a good starting point if you need real index numbers rather than illustrative ones for your specific comparison.

The housing-driven share is estimated by applying your housing weight to the total dollar gap between the two salaries, which approximates how much of the overall cost difference traces back to housing specifically rather than the full basket of goods and services. This is an estimate, not a precise decomposition — actual index providers publish separate sub-indices for housing, groceries, transportation, healthcare, and miscellaneous goods, and if you have access to those specific numbers for your two cities, they'll give you a more accurate housing share than the single weight this tool uses.

Why Housing Is Almost Always the Real Story

When people hear that a city is "40% more expensive," they often picture everything costing 40% more — groceries, gas, restaurants, insurance. In reality, most of that headline number comes from one category: housing. Rent and home prices vary enormously between US metros, sometimes by two or three times, while groceries, gas, and most consumer goods vary far less because they're sold in national or regional markets with competitive pricing. A typical breakdown might show a city that's "40% more expensive overall" actually running close to national average on food and transportation, moderately above average on healthcare, and 80-90% more expensive specifically on housing — with that one category dragging the blended average up to 40%. That's why this calculator surfaces a housing-driven share explicitly: it reframes "this city costs 40% more" into something closer to the truth, which is usually "this city's housing market costs a lot more, and the rest is close to what you're used to."

This matters practically because a relocation raise that simply matches the blended cost-of-living index can still leave you no better off if your actual spending doesn't match the index's assumed weights — for example, if you rent a small apartment rather than buying a large single-family home, the housing gap you personally experience may be smaller than the published index implies, and a raise pegged to the full index would actually overshoot what you need. The reverse is also true for a family that needs significantly more housing space in the new city than the index assumes.

The "Purchasing Power" Number Explained

The purchasing power figure in the results grid answers a different but related question: if you moved to the target city and kept your exact current salary with no raise at all, how much would that salary actually be worth there, expressed in "current city" dollars? This number is calculated by applying the inverse of the cost ratio to your current salary, and it's often the most sobering figure on the page for anyone moving to a materially more expensive city without negotiating a corresponding raise — a $75,000 salary in a city with a 140 cost index is worth roughly $53,600 in current-city terms, a meaningful real pay cut even though the number on the paycheck hasn't changed.

Combine This With a State Tax Comparison

Relocation decisions almost always involve both a cost-of-living change and a state tax change simultaneously, and it's easy to let one distract from the other. Someone moving from a high-cost, high-tax state to a lower-cost, no-income-tax state gets a genuine double benefit; someone moving from a high-cost, low-tax state to a lower-cost, higher-tax state may find the tax increase eats into some of the cost-of-living savings. Run our take home pay by state calculator alongside this tool any time a real move is on the table, so you're looking at the full financial picture rather than one variable at a time.

• Use this tool to find the equivalent salary for maintaining your standard of living in a new city.
• Use the take home pay by state calculator to see how state income tax changes independently of cost of living.
• Use both together before accepting or declining a relocation offer.

Common Mistakes to Avoid

• Assuming a relocation raise that matches the cost index makes you better off. It typically only maintains your current standard of living — it's not a real increase in purchasing power.
• Applying a national cost index to your personal spending pattern without adjustment. If you rent rather than own, or spend little on categories the index weights heavily, your personal gap may be smaller than the published number.
• Ignoring state and local tax differences alongside cost of living. The two effects can reinforce or cancel each other out depending on the specific move.
• Treating a single index number as precise to the dollar. Cost-of-living indices are estimates built from sampled prices and vary somewhat between publishers.
• Forgetting that cost indices change over time. A city's relative affordability can shift meaningfully within a few years as housing markets move.
