Keeping track of costs is so important for any business. If you don't know how much blast cleaning is costing you, then you may not be charging your client enough.
Using the formula shown below will help you keep track of your costs and help you cover your expenses:
Blaster Bob buys a cheap abrasive at a cost of $150/tonne and a 6 cu ft pot lasts 30 minutes (i.e. 600kg per hour). He blasts 15m² of steel in 1 hour.
Blaster Pete buys a superior abrasive at a cost of $550/tonne and a 6 cu ft pot lasts 1 hour (i.e. 300kg per hour). He blasts 20m² of steel in 1 hour.
The difference between Blaster Bob and Blaster Pete’s True Cost is $0.75/m². And remember, in this example, Blaster Pete paid $550/tonne for a superior abrasive with minimal salt levels, less contaminants and less dust!
So, the more expensive abrasive resulted in lower costs. Calculate the True Cost using your figures and overheads.
