This is the floor, not the price. What you charge above it is a commercial decision; what you charge below it is a subsidy.
1,610 hours is a working year after leave and public holidays. Utilisation is applied to that, which is why a small change to it moves the rate more than a large change to salary.
It builds charge rates from cost rates and a target margin, per role, and shows what recovery each rate implies.
Most rate cards are set by looking at competitors and rounding. That works until costs move and nobody notices the margin has gone.
Enter salary and employer costs per role, then genuinely available hours — after holidays, leave and non-project time. That gives cost per available hour, which is the real cost rate.
Apply your target margin. The resulting rate is what you would need to charge; whether the market pays it is the next question.
It will not tell you what the market will pay. That is a commercial question this cannot answer.
It also excludes overhead deliberately — add your own recovery figure if you want a fully absorbed rate.
Compare the calculated rate against what you actually charge. A role where the two diverge sharply is either underpriced or being subsidised by another role.
Check the junior roles particularly. They are often priced by proportion to senior rates rather than by cost, and they are where blended-rate work quietly loses money.
Available. Contracted hours understate cost by roughly a fifth.
No — add your own recovery if you need it.
No, by cost. That is where blended work loses money.
Half an hour on your own figures, and an honest answer about the parts Treepie does not improve.
