The Timezone Salary Converter compares the equivalent salary you would need in different cities to maintain the same purchasing power as your current location. Uses Cost of Living Index (COLI, with NYC as 100 baseline) to compute equivalent salaries across 20 major US and international cities including San Francisco, NYC, Boston, Austin, Mexico City, London, Tokyo, Mumbai, Singapore, and others. Critical for remote work salary negotiations, relocation planning, and evaluating job offers across geographic markets. The formula is straightforward: Equivalent Salary = Current Salary × (Target City COLI / Current City COLI). A $100,000 SF salary (COLI 178) translates to roughly $60,000 in Austin (COLI 107) for equivalent purchasing power — meaning a 40% pay cut maintains the same lifestyle. This counterintuitive result drives the remote work relocation trend: tech workers moving from SF to Austin, Miami, or Phoenix while maintaining or increasing real income despite nominal pay cuts. Cost of Living Index combines housing, food, transportation, healthcare, and entertainment costs weighted by typical household spending. Numbeo (most widely cited source) updates regularly based on user-submitted data. The calculator's 20 cities provide a starting framework — individual lifestyle varies (heavy renters affected more by housing cost differences, families affected by school quality not captured in COLI). Use the calculator's output as directional rather than precise. This calculator helps with major financial decisions. Enter current annual salary, select current city and target city. The calculator outputs equivalent salary needed, purchasing power percentage, and absolute dollar difference. Use for: remote work salary negotiations (employer may not adjust by full COLI ratio, creating windfall), relocation analysis (real estate buying decisions, school district considerations), career planning across regions, and comparing job offers from companies in different cities.

How accurate is Cost of Living Index?
COLI is averaged across housing, food, transportation, healthcare, entertainment. Individual lifestyle varies significantly. Use as directional starting point; adjust for your specific spending patterns (renter vs homeowner, urban vs suburban, family size).
Should I consider tax differences?
Yes, dramatically. State income tax varies 0% (TX, FL, WA, NV) to 13.3% (CA). Federal tax is consistent. International tax varies wildly — UK 40% high bracket, Mexico 30%, Singapore 22%. Always compute after-tax equivalents for major decisions.
プロのヒント
Always negotiate based on equivalent purchasing power, not nominal salary. Moving from Austin to NYC with a 20% raise is actually a pay cut after cost-of-living adjustment.
