How to compare a salary between two cities, step by step
Start with your current gross salary: enter it with your current city as the base and the
offer city as the destination. The equivalent-income figure the calculator returns is your
benchmark — the rough gross you would need in the new city to stand still. An offer below
it suggests a lifestyle cut on paper; an offer above it suggests headroom. If rent will be
your biggest line — for most renters it is — toggle rent-weighted mode and check whether
the benchmark shifts much. Then put both salaries through the take-home estimator so you
are comparing rough net against rough net, not gross against gross; two countries can tax
the same salary very differently. Finally, sanity-check the winner against real local
prices before you sign anything.
Which costs dominate a cost-of-living comparison
Housing is the number that usually decides whether a move works: for most city dwellers,
rent or a mortgage typically takes 30-50% of spending, and rents often diverge between
cities more sharply than day-to-day costs like groceries. That is what rent-weighted mode
is for — if you rent, the plain overall index can understate the real gap. After housing,
the big swings come from things a headline index barely captures: childcare (which in some
cities rivals rent), healthcare and insurance (a major line in the US, often covered
through taxes or payroll contributions elsewhere), and income tax. Groceries, utilities,
and eating out differ too, but rarely enough on their own to change a relocation decision.
Beyond the relocation calculator: a pre-move checklist
A city-wide index is a starting point, not a budget. Before you accept an offer or sign a
lease, pin down the handful of numbers that will actually shape your month: current asking
rents on local listing sites for your specific neighbourhood and apartment size, not the
city average; the commute you would really do, priced in both money and time; health
insurance or healthcare contributions for your situation; and school or childcare fees if
you have kids, since these vary widely and rarely show up in headline indices. Add the
one-off costs — deposits, agent fees, furniture, flights — which can easily eat one to
three months' rent. The take-home estimator here is deliberately simplified, so get your
exact tax position from the destination's own tax authority.
