A winding-stick sighting is useless if one stick is thicker than the other. The pair has to match. A rate for leftover-hour work has the same requirement: the number a platform or a client names is one edge; the hours actually spent, plus fees, tools, travel, and recovery, are the other. If those edges do not agree, the rate is in wind. This is an accounting picture, not a claim that any rate will raise a household's income.
Self-employment and platform work often publish a gross figure. The ILO and national statistical offices treat net earnings after costs as a different object from that headline. Katz and Krueger's 2016 working paper on alternative work arrangements was later revised downward in a 2019 paper in the Journal of Labor Economics; the revision is part of the grain, not a footnote. Counts of extra work move when definitions move. A rate that ignores that movement sights along one stick only.
Costs that tilt the far edge are ordinary. Payment processing fees, software subscriptions, replacement of a tool, unpaid messages before a job is accepted, and commuting to a second workplace all sit outside the advertised number. So does the next morning at the main job if the extra work ran late. Occupational research on long combined hours, including reviews collected by the ILO, treats that morning as part of the week's load, not as free capacity.
Taxes and social contributions vary by country and by status. This desk does not give tax advice. The only editorial point is that a rate which is not reduced by the contributions a worker actually owes is a thicker stick than the one on the board. Alignment is a check after those items, done by the person who pays them, with a professional where the law requires one.
None of this recommends a number. Some leftover-hour work is unpaid by design: study, care, a family task. Some paid offers are below any aligned rate once costs are visible, and declining them is a reading, not a failure. The library does not forecast earnings. It only asks that both sticks be the same length before anyone treats a headline figure as level.
