- Markup vs Margin for Plumbers: 25% Markup Is a 20% Margin
Same profit, two denominators, and they can never be equal. The conversion both ways, why the gap widens with ambition, and what a 25% mix-up costs across a year of ordinary work.
- Plumber Hourly Rate: Utilisation Moves It More Than Wage Does
A $32 an hour plumber bills $117.44 — 3.67x the wage. Not greed: it is burden, overhead, and the 680 paid hours a year that nobody buys. And utilisation moves the rate further than a pay rise does.
- How to Estimate Plumbing Jobs: Markup Is Not Margin
A 25% markup delivers a 20% margin, and on a $2,760 job that is $230 left on the table. The build-up in order, why overhead is a separate line, and the division that turns break-even into a price.
