Step-by-Step Examples
Rent $6k, software $3.6k, insurance $1.2k, marketing $4.8k, admin $2.4k, $80k labour.
- Total overhead: $18,000
- Rate: $18,000/$80,000 = 22.5%
- For every $100 billed, $22.50 goes to overhead
$60k rent, $20k software, $15k insurance, $30k marketing, $20k admin, $500k labour.
- Total overhead: $145,000
- Rate: $145,000/$500,000 = 29%
$0 rent, $2.4k software, $0.6k insurance, $1.2k marketing, $1.2k admin, $60k labour.

- Rate: 9% — low overhead is the home business advantage
Real-World Applications
Common Mistakes to Avoid
Overhead includes everything that isn't direct labour or materials: rent, utilities, software, insurance, marketing, legal, accounting, and owner's non-billable time.
Overhead rates change as you hire or as costs increase. Recalculate quarterly.
If the owner does sales, marketing, and admin, that time should be in overhead. Many small businesses understate overhead by ignoring owner's non-billable hours.
