Comparing pay between regions without fooling yourself

There is a settled way of talking about regional pay comparison. It is worth asking how much of it survives contact with the detail.

Housing is most of the difference

Regional cost variation is driven far more by housing than by groceries or services, which differ much less between areas. That means the correct first adjustment is pay after housing cost rather than a general cost-of-living index.

Comparing residual income after rent or mortgage across two locations is a more honest comparison than comparing salaries. It frequently reverses the apparent ranking of two offers.

Commuting is part of the housing decision

Cheaper housing further from work usually costs more in fares or fuel and in time, which has its own value. Adding the annual transport cost to the annual housing cost gives a single figure that can be compared between options. Pricing the commuting hours at your hourly rate makes the time cost explicit as well.

The break-even distance is often shorter than people assume.

Location allowances are approximations

Where employers pay a location supplement, it is usually a flat regional figure rather than a calculation of your actual costs. It may be substantially more or less than the real difference for your circumstances.

Where it helps most, whether it is consolidated into base pay or paid separately affects pension, overtime and future percentage rises. Ask which it is, because a non-consolidated allowance can be withdrawn or frozen.

Career effects are part of the calculation

Some regions have deeper labour markets in particular specialisms, which affects how easily you find the next job as well as this one. That option value is real and is difficult to quantify, so it is best stated explicitly rather than folded into a number. Remote work has reduced but not removed the effect in many fields.

It matters most for narrow specialisms with few local employers.

Remote roles are priced inconsistently

Employers vary between paying a single rate regardless of location and adjusting pay to where the employee lives. The policy can change, and some employers have adjusted pay after employees relocated. Getting the current policy in writing before moving is the practical protection.

Ask specifically what happens if you move to a cheaper or more expensive area.

Currency and tax cross borders badly

International comparisons need adjustment for tax, social contributions, healthcare costs, pension arrangements and typical employer benefits, which differ fundamentally. A headline salary converted at the exchange rate tells you very little on its own.

Net income after housing, tax and health costs is the only comparable figure. For a cross-border move, professional tax advice in both countries is warranted rather than optional.

The takeaway

Compare what is left after housing and getting to work. That is the only comparable number.

Pick the one that costs you least, and let the rest wait.
