Profit – 12%

For every $100 in sales, the business should have $12 the bank left over. Is this your profit margin? If not let’s see why it’s different.

Purchases – 37%

“Sole Proprietors drawing an income from profit can inflate industry profit margins and wage costs”

Other – 20%

Other is made up of all other expenses that make up the costs of running the business. I.e. Subcontractors (10%), Motor Vehicle Expenses (5%), Insurance, Repairs and Maintenance, professional fees etc.
For every $100 in sales, $20 should be going to Operating Costs.

Depreciation – 2%

Decline in value of equipment.
For every $100 in sales, $2 should be from the depreciation of equipment (non-cash item).

Rent – 1%

Most small contractors don’t rent out an office or warehouse space, so if you don’t you should see this amount left over in the bank.

What to do next

These benchmarked ratio’s give a good indication for improvement areas for your business. If Wages are too high, are your staff spending more time travelling to pick up supplies too frequently? If Materials are too high, have you got your Materials to mark up right? Or you might have issues with wastage of Materials.
