Free Cost of Living Calculator — City-to-City Salary Equivalence (66 Cities)

What This Calculator Does

A cost-of-living calculator answers one tightly scoped question: how much would I need to earn in City B to keep the same purchasing power I have in City A? It is not a job-offer evaluator, not a tax calculator, and not a quality-of-life rater. It translates a salary across cities using a single index and tells you the equivalent number.

The math behind it is short. Each of the 66 cities in our index has a number — New York City is pegged at 100, every other city is scaled relative to it. If your target city has an index of 70, the calculator multiplies your current salary by 70 / 100. That ratio is the entire engine. The calculator also reports the delta in dollars and the percentage adjustment so you can see at a glance whether the move is a raise, a cut, or a wash in real-purchasing-power terms.

Use it for relocation conversations with HR, for comparing remote-work offers in different cities, for deciding whether a transfer with a 15% “raise” is actually a raise, and for sanity-checking whether the dollar number on a contract is competitive with what you already have. It is fastest where it matters most: the first thirty seconds of an offer-evaluation conversation.

How the Cost-of-Living Index Works — The Math

The index is an aggregate of six everyday spending categories:

• Rent — typically the largest single line item and the biggest driver of regional variation.
• Groceries — staple foods, dairy, produce, meat at supermarket prices.
• Transit — public transport passes, fuel where car ownership is the norm.
• Dining — mid-range restaurant meals and casual eating out.
• Utilities — electricity, heating, water, internet for a typical apartment.
• Goods & services — clothing, personal care, gym membership, entertainment.

Each city’s basket cost is divided by NYC’s basket cost and multiplied by 100. That gives a single dimensionless number — the index — that lets you compare two arbitrary cities with one division. The data comes from Numbeo’s aggregate cost-of-living index, the most widely cited crowdsourced dataset for cross-city comparisons. Numbeo’s methodology weighs the categories above into a single “all-in” number which we then re-normalize so NYC sits at exactly 100.

What’s Not in the Index

The index is deliberately narrow. It captures the basket — and only the basket. Several large categories are intentionally excluded, because they vary too much by individual to be meaningfully averaged:

• Income tax. A $200k gross in Texas (no state income tax) lands very differently from $200k gross in California (top marginal ~13.3%). Two cities with similar cost-of-living indexes can have a ~$15,000 take-home delta purely from tax. Always translate to net before comparing — see our take-home pay calculator.
• Healthcare. A US-vs-Europe comparison changes radically once you account for who pays for healthcare. The same $80k that feels tight in Houston (with a $700/month family premium plus deductibles) is comfortable in Berlin (statutory health insurance deducted at source, ~7.3% of gross, with no separate premium).
• Commute. A 90-minute Bay Area commute from a cheaper suburb is not captured anywhere in the rent line. The index assumes you live where you work; people who actually do that pay the higher rent the index already reflects.
• Childcare and schooling. Daycare in Manhattan can run $36,000/year per child; in Mumbai it can be a tenth of that. For families this single line item often dwarfs every other category combined.
• Lifestyle preferences. If you eat out three times a week and the index assumes once, your real cost runs higher than the index suggests. The basket is a national average of habits, not yours.

The takeaway: the index gives you a fast, honest first answer. It is not the final answer. For a relocation involving large compensation, run the equivalent salary number through a net-pay calculator, then layer in the categories above as separate adjustments.

How to Use This Calculator

1. Pick your current city from the dropdown. This is the baseline — the place you live now and whose cost-of-living you already understand intuitively.
2. Pick the target city. The calculator looks up both cities’ indexes and divides them.
3. Enter your current salary in your reporting currency. The calculator does not convert currencies — it returns the equivalent figure in the same unit you put in. If you need to convert across currencies, run the result through our currency converter after.
4. Read the three outputs together: the equivalent salary (what to ask for), the index ratio (the multiplier explaining the move), and the percentage adjustment (the headline number for negotiation conversations).

Three Worked Examples

Three real moves at different points on the spectrum — copy the numbers into the calculator above to see how the index ratio drops out.

Example 1 — New York City to San Francisco (similar)

$100,000 in NYC (index 100) translates to $105,000 in San Francisco (index 105). A 5% bump on paper, equal purchasing power on the basket. The two cities are notoriously close on the index — they trade places at the top depending on the year — so HR’s “5% COLA adjustment” is mathematically correct.

The catch: California state income tax is roughly 9.3% at this income, while New York’s is around 6.5%. The 5% gross-equivalent bump is almost entirely consumed by the tax delta before you ever spend it on the higher-cost basket. Net-of-tax purchasing power is slightly worse in SF for this exact move. This is the classic case where a cost-of-living index lies by omission — the answer in gross equivalent terms is clean, but it is the wrong question once tax is in the picture. Pair the result with net pay for the conversation that actually matters.

Example 2 — NYC to Mumbai (huge drop)

$100,000 in NYC (index 100) translates to $28,000 in Mumbai (index 28). A 72% pay cut on paper, same basket. This is the math that makes outsourcing arrangements work and the math that startles people considering reverse-relocation moves.

The number is correct, but it is not the whole picture. Mumbai at $28k buys the same rent, same groceries, same transit, same dining as $100k bought in NYC — that is what the index guarantees. What it cannot tell you is whether you want the lifestyle tradeoff that comes with it: monsoons and air-quality challenges instead of four seasons, dramatically different infrastructure expectations, a different healthcare system, and a different career market. For a remote worker keeping a US salary, the same $100k in Mumbai represents an enormous real raise — roughly 3.5× local purchasing power. For a local hire, the same $28k is the market clearing price. Both numbers are right; the calculator is just doing arithmetic.

Example 3 — London to Berlin (modest drop)

£75,000 in London (index 84) translates to £58,000 in Berlin (index 65). A 23% lower equivalent salary maintains the same basket-purchasing-power. This is the math behind the steady London-to-Berlin migration of tech workers in the late 2010s and early 2020s.

Quality-of-life metrics often favor Berlin: more affordable rent for similar square footage, comparable public-transit infrastructure, healthcare included via statutory contributions, and significantly more disposable income for the same job tier. The index captures the headline rent and groceries delta — Berlin rent is roughly half of London for an equivalent flat — but the “feel rich” effect of moving is even stronger than the 23% number suggests once you net out tax and add free healthcare. This is the case where the calculator understates the upgrade rather than overstating it.

Common Mistakes

• Comparing gross salaries across countries with different tax regimes. A £75k London gross and a $100k NYC gross are not directly translatable even after cost-of-living adjustment, because they are taxed in different systems with different deduction rules. Convert each to net first, then apply the index.
• Ignoring rent as a fraction of the basket. Rent dominates the index in high-cost cities — sometimes 40–50% of the entire basket — but if you already own your home outright, your personal index is far closer to neutral than the city-level number implies. The calculator assumes you are renting at market.
• Treating the index as a quality-of-life ranking.Mumbai’s index of 28 is a price tag, not a verdict. Cities with low indexes are not “worse” — they are cheaper. The conflation of cheap-with-bad is the single most common reading error.
• Using an outdated city index.Rent has moved 20–40% in some metros over three-year windows. A 2021 index applied to a 2026 decision is meaningfully wrong. We refresh against Numbeo’s rolling aggregate, but always sanity-check rent against a live local listing site for the destination.
• Forgetting one-time relocation costs. A move costs $5–25k between shipping, deposits, broker fees, visas, and short-term housing. The equivalent-salary number is steady-state; the first year always runs worse. Budget the move as a separate line item.
• Anchoring on the percentage instead of the dollar gap. A 30% pay cut looks scary; if it preserves purchasing power on a $90k base, it leaves you with the same life for $63k somewhere cheaper. The dollar-equivalent in the local economy is the right comparison point, not the percentage relative to your old paycheck.

When This Calculator Decides For You

The output usually maps directly to a real decision. The four most common ones:

1. Negotiating an internal transfer.If HR offers you a relocation package with a salary “adjustment” that is below the index ratio, you are taking a real pay cut even though the dollar number went up. Counter with the equivalent-salary figure and the index ratio as your evidence.
2. Evaluating two job offers in different cities.Translate both to your current city’s index. The higher equivalent number is the better offer in purchasing-power terms — independent of the headline dollar amount.
3. Remote-work salary policy.If your employer pays a flat “US salary regardless of location”, the calculator tells you the local-market arbitrage you gain by living in a low-index city. If they pay localized rates, it tells you what fairness looks like.
4. Lifestyle decisions. Can I afford the same life on a part-time consulting income in a low-cost city? Plug in your current salary and target a 60–70% equivalent — that is the local income that buys your existing basket back.

Net (After-Tax) vs Gross Comparison

The calculator reports a gross-equivalent salary by default. That is the right number for negotiation conversations, where both sides talk in pre-tax dollars. It is the wrong number for budgeting decisions, where what hits your account is what matters.

Two cities with identical cost-of-living indexes can have very different net outcomes. A $150k gross in Austin (no state income tax, ~24% effective federal) nets roughly $114k. The same $150k gross in San Jose (top-bracket California state tax, ~9.3% on top of federal) nets closer to $100k. The cost-of-living indexes are within a few points of each other, but the take-home-pay delta is real — about $14,000/year, or roughly 10% of net.

For a defensible cross-city comparison, run a four-step pipeline: (1) compute the equivalent gross salary using this calculator’s index ratio, (2) feed both salaries through take-home payfor each jurisdiction’s tax math, (3) compare the two net figures, (4) re-apply the index ratio to the net side to get a final purchasing-power number. Most people stop at step one and end up surprised twelve months later.

The 66-City Snapshot — Limits and Use

The dataset covers 66 of the world’s most-searched relocation destinations. Coverage is heaviest in North America, Western Europe, and major Asian metros. Smaller cities, rural areas, and second-tier metros in any country are not included — by design. The 66 chosen cities account for the overwhelming majority of relocation searches, and the index is calibrated tightest there.

That has two practical implications. First, if your move is between two cities both in the list, the equivalent number is reliable to within a few percentage points of any cross-checking source. Second, if your move is to a small town near a listed metro — say, Albany NY when only NYC is in the list — the listed metro’s number will overshoot the small town’s real cost-of-living, often by 20–40%. In that case, treat the listed metro’s index as an upper bound and adjust manually.

Indexes update on a rolling basis as Numbeo’s aggregate updates. We hold a city constant for the duration of any single calculation but refresh the snapshot regularly. For decisions over $20k of compensation impact, always cross-check the destination city’s rent against a live local-listing site — that single line dominates the index, and it moves faster than any aggregate dataset can keep up with.

For follow-on math, pair this calculator with the salary-to-hourly calculator if your target role is hourly or contract, the true hourly rate calculator to back out commute, prep, and unpaid-overtime hours from the headline number, and the currency converter for any cross-border move where the input and output are denominated in different currencies.
