Frequently asked questions

Why show the median instead of the average?

The median (33 636 £) is the middle of the market: half of the offers pay more and half pay less. Unlike the average (43 838 £), it is not skewed by a handful of very high salaries.

What does the typical range mean?

From 27 326 £ to 69 691 £ is the middle half of all offers — the 25th to 75th percentile. A quarter of vacancies pay below 27 326 £ and a quarter above 69 691 £.

Where does the data come from?

From 56 open vacancies with a stated salary that Finder collects from public sources. Numbers are recalculated as the selection changes.

How do I tell whether I am paid fairly?

Compare your pay with the median and the quartiles: near 33 636 £ is the market level, above 69 691 £ is the strong quarter, below 27 326 £ is a reason to negotiate. Use the “Compare my salary” button on this page.

How we calculate salaries

Short methodology and the data behind these numbers.

  1. 1We collect offersOnly vacancies from open sources where the employer states pay are used.
  2. 2We normalise themA salary range is reduced to one comparable value per vacancy.
  3. 3We compute percentilesMedian, quartiles and the average are calculated from at least 5 offers; otherwise the wider country market is shown.
  4. 4We refresh the numbersStatistics are recomputed as new vacancies appear and closed ones drop out.

Figures are pay as published by employers: taxes, bonuses and seniority inside a grade are not accounted for.
