Cost of Living Calculator

What this calculator does and who it’s for

The Cost of Living Calculator lets you put two of fifteen popular expat destinations side by side and see, in pounds, roughly what a month of ordinary living costs in each. It is built for the questions people actually ask before an international move: is the new posting going to leave me better or worse off day to day, and which parts of the budget change most? Whether you are weighing a corporate relocation to Dubai or Singapore, choosing a lower-cost base in the Mediterranean, or planning where to spend a longer retirement abroad, the tool turns a vague sense of “expensive” or “cheap” into a concrete monthly and annual figure. It sits alongside the rest of our calculators and tools and is aimed at internationally mobile professionals, retirees and families doing early-stage planning.

How the comparison works

Each location carries an indicative monthly figure for six everyday categories: rent or housing, groceries, transport, utilities, dining out and healthcare. The tool sums those six lines into a monthly total for each destination, then does three things with the numbers. First, it produces a cost index, rebasing every location against London, which is fixed at 100 — so an index of 120 means costs run about a fifth higher than London, and 60 means about two-fifths lower. Second, it shows the monthly difference between your two chosen locations and flags whether the move is a saving or an extra cost. Third, it annualises that gap by multiplying by twelve, because a modest-looking monthly difference compounds into a meaningful yearly number.

A worked example makes it concrete. Using the tool’s indicative figures, a single professional in London spends roughly the London baseline each month across the six categories, which anchors the index at 100. Compare London with Dubai and the total comes out higher in Dubai — the calculator surfaces the extra as a monthly figure and shows what it adds up to over a year. The breakdown table underneath makes the story readable line by line: you might find Dubai cheaper on groceries but dearer on rent, dining and utilities, with a healthcare line that appears in Dubai but shows as zero for London. That category-level detail is usually more useful than the headline total, because it tells you where the money goes and which trade-offs you can influence.

What the figures include — and what they leave out

The estimates describe a single professional living a mid-range lifestyle: broadly, someone renting a one-bedroom apartment in an accessible central or near-central neighbourhood, eating out two or three times a week, and using public transport regularly. Figures are drawn from published expat surveys, rental indices and general market research, and are converted to pounds at approximate exchange rates so that every destination sits on one comparable scale. Because they are expressed in sterling, the real local-currency cost will move with exchange rates — one reason currency management is a live issue for expats, and worth modelling separately with our FX transfer calculator.

Just as important is what the tool deliberately excludes. It does not include income tax, social contributions, international private health insurance, international-school fees, or the cost of flights home. Several of these can be large. School fees in hubs such as Singapore, Dubai and Hong Kong routinely run into five figures per child per year and can easily outweigh the living-cost gap the calculator shows. Tax is the other big omission, and it cuts both ways: a destination with higher gross costs but no income tax, like the UAE, can still leave you materially better off in net terms. One note on the healthcare line: London is shown as £0 on the assumption of NHS access, but expats who have left the UK and are no longer ordinarily resident generally lose entitlement to free NHS treatment and must budget for local or international cover.

How to read your result

Start with the index to rank the two locations, then read the breakdown table to understand the drivers, and finally look at the annualised difference to grasp the real scale. A £500-a-month gap is £6,000 a year — enough to change a relocation decision, negotiate a cost-of-living allowance, or fund a return flight budget. The single most important mental adjustment is to convert the tool’s gross figures into a net comparison by layering in your expected after-tax income in each location. That is why a low-tax destination can win even when its raw costs look higher, and why a headline “cheaper” country can disappoint once local taxes and mandatory insurance are added. Before committing, it is also worth pinning down your tax-residence position — our UK Statutory Residence Test helps you check whether you would still be UK-resident, which directly affects how your income and gains are taxed.

Why it matters and what to do next

Cost of living is one input into a much larger relocation decision. Getting the everyday budget roughly right is valuable, but the parts the calculator cannot see — tax residency, pension arrangements, protection cover, currency exposure and how you hold your investments — are usually what determine whether a move works financially over the long run. For a fuller picture of the trade-offs between destinations, our guide on how much you need to retire abroad works through realistic income and capital requirements country by country, and the expat financial planning hub covers banking, tax, pensions and protection for people on the move. Use this tool to frame the question, then take advice on the structure before you commit to a destination.
