I thought I would post a short piece of the book if anyone might be curious. I still want to give this to people on here as I really think it is a very useful resource to have.
None of the work below belongs to me, but it may be shared.
MINIMUM HOURLY RATE FOR A SOLE TRADER
The following sample calculation shows the process required to determine a minimum hourly rate for a sole trader operating in the local area, performing a combination of service work and small installation jobs. The rate is developed to allow for low sales of materials.
For this example, it is assumed that the contractor operates the business from home, and has no unnecessary overhead commitments. It is assumed that the contractor is able to achieve a productivity that allows 30 hours per week as chargeable work, with the remaining 8 hours lost on non chargeable tasks such as traveling, preparing quotes, bookwork, etc. This 8 hour non productive time becomes an overhead.
On costs are assumed to be 38%, which reflects a common value for many contracting operations.
The contractor has chosen to aim for a wage of $35.00 per hour.
Labour cost per hour = $35.00 + 38% = $48.30 per hour
Overheads are as follows
Van = $15,000.00 per annum (includes all running, insurances and depreciation)
Telephones (mobile and land line) = $3,000.00 per annum
Insurances (public liability, fire, theft) = $2,000.00 per annum
Accountancy fees = $1,500.00 per annum
Advertising, petty cash, entertaining, etc = $100.00 per week or $5000.00 per annum
Tool replacement = $1,500.00 per annum
Non productive hours = 8 hours x 44.2 weeks = 353.6 @ $48.30 = $17,078.00
Total overheads = $28,000.00 + $17,078.00 = $45,078.00
Hourly overheads = total overheads = $45078 = $34.00 per hour
productive hours 44.2 x 30hrs
Therefore the minimum hourly rate, to achieve a wage (without profit) is
$48.30 + $34.00 = $82.30 per hour
If this is not available in the market, the contractor should not continue to trade, or should change the area of trading.
