How to calculate it
Annual overheads not charged to jobs, divided by annual turnover. Every tender must carry this before profit.
Why it matters
If it isn't in the tender, the job is priced at cost plus optimism.
The Taxtful view
Recalculate it every year. It rises as the office grows and almost nobody updates the tender template.
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.
