How to Calculate Your Cost of Living Adjustment When Relocating for a New Job
Published July 16, 2026
Getting a job offer in a new city is exciting - until you start wondering whether the salary actually covers the same lifestyle you have today. A "10% raise" can be a pay cut in disguise if you're moving from a low-cost metro to an expensive one, and a "lateral move" can be a huge raise in real terms if you're moving the other way.
Step 1: Start from your current cost of living, not your current salary
The number that matters isn't your salary in isolation - it's your salary relative to what things cost where you live now. Two people earning $70,000 can have wildly different standards of living depending on their city's housing costs, taxes, and everyday prices.
Use our cost of living index for your current city and your prospective city. Every city page shows an index where 100 equals the US national average - a city at 130 is roughly 30% more expensive overall than a city at 100.
Step 2: Use the ratio, not the raw difference
The simplest reliable formula is:
Required salary = Current salary × (Target city index ÷ Current city index)
For example, if you earn $75,000 in a city with an index of 95, and you're moving to a city with an index of 140, you'd need approximately $75,000 × (140 ÷ 95) ≈ $110,500 to maintain the same standard of living. This is exactly the calculation our city pages run automatically in the built-in salary calculator - enter your current city and salary on any destination city's page and it does the math for you.
Step 3: Don't stop at the headline number - check the breakdown
The overall index is a weighted average, but your personal spending pattern might not match the weights. If you rent rather than own, housing matters more to you than the average homeowner. If you don't drive, the transportation index barely applies. Every city page breaks the index down into housing, transportation, food, utilities, and healthcare so you can weight it yourself.
Step 4: Remember taxes are part of "cost of living" too
A city with cheap rent but high state income tax can end up costing more than it looks. When comparing two offers, look at take-home pay, not gross salary - a $5,000 raise disappears quickly if you're moving from a no-income-tax state to one with a 7-8% top bracket.
Step 5: Sanity-check with a direct city comparison
Beyond the calculator, it helps to see two cities side by side. Our city vs. city comparison pages (for example, searching any two cities together) show housing, food, transportation, and wage data in one table, so you can spot which specific category is driving the difference instead of just trusting one composite number.
The bottom line
A relocation offer should be evaluated as a ratio, not a raw number. Before you accept or negotiate, run your numbers through the index, check the category breakdown for your specific lifestyle, and factor in taxes. It takes ten minutes and can be worth tens of thousands of dollars over the life of the job.
