Working abroad real return.

Working abroad financial decision: nominal salary uplift vs cost-of-living adjustment vs relocation costs. Pure salary increase often offset by higher cost of living and one-off relocation costs. This tool calculates net financial gain over the assignment period.

50k home (CoL 100), 80k abroad (CoL 130). Real abroad value: 80k × (100/130) = 61,538. Annual real difference: 11,538. 3-year assignment = 34,615 difference. Minus 15k relocation + 10k return = 25k. Net gain: 9,615 over 3 years. Marginal financial benefit; main value is career and life experience.

Most international assignments are net-neutral financially after all costs. The real value comes from: career progression (return promoted), tax-free savings (some assignments offer tax equalisation), pension banking (continue home pension while paying lower local tax), professional network expansion. Pure salary increase rarely justifies international move financially.

Run it with sensible defaults

Using home salary of 50,000, abroad salary of 80,000, abroad cost of living index of 130, home cost of living index of 100, the calculation works out to 9,615.38. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Home Salary, Abroad Salary, Abroad Cost of Living Index, Home Cost of Living Index, and Relocation Cost — do not pull with equal force. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

How the math works

Real abroad value = abroad salary × home CoL ÷ abroad CoL. Annual diff = real abroad - home. Total = annual × years - one-off costs. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

Using this in pay negotiations

Knowing the exact figure behind a headline rate gives you specific numbers to anchor to in conversations about pay. "The difference is £X per month after tax" lands harder than "a couple of grand a year". Concrete numbers move decisions.

What this doesn't capture

Tax bands, pension contributions, student-loan deductions, and benefits-in-kind sit outside this calculation. The figure is the headline; your actual position depends on local tax rules and personal circumstances. Pair with a dedicated take-home calculator for the full picture.
