How to calculate it
Overheads (office, admin salaries, vehicles not on site, insurance, professional fees, finance) divided by certified revenue.
Why it matters
The fixed cost the business has to clear every month before a job contributes. When revenue dips, this is why profit disappears faster than it should.
The Taxtful view
Above 15% for more than a quarter is a structural review, not a bad month.
Every Taxtful client sees this number on their Taxtful View each month, with the benchmark alongside. Benchmarks are drawn from our own client base and published sector data; ranges vary by trade and contract type.
