Bonding Capacity Calculator
In the world of construction and contracting, bonding capacity is a crucial indicator of how much work a contractor can be bonded for at any given time. It is often used by surety companies, project owners, and contractors themselves to determine the maximum amount of bonded work a company can handle based on its financial health—especially working capital.
The Bonding Capacity Calculator helps simplify this financial assessment by using the industry-standard approach of multiplying a company’s working capital by a bonding multiplier. This tool is vital for understanding your financial readiness for larger projects and qualifying for public or private tenders.
Formula
Bonding Capacity = Working Capital × Bonding Multiplier
Where:
- Working Capital = Current Assets − Current Liabilities.
- Bonding Multiplier = Typically ranges from 5 to 20, depending on financial stability and surety underwriting criteria.
The result gives you the maximum bonded contract value a surety may approve.
How to Use the Bonding Capacity Calculator
- Enter Your Working Capital: Use your balance sheet to get current assets minus current liabilities.
- Enter the Bonding Multiplier: Typically provided by a surety agent or based on your creditworthiness (e.g., 10).
- Click “Calculate”: The calculator will instantly display your bonding capacity in dollars.
This helps you assess whether you can qualify for a specific contract amount or need to improve your financials first.
Example
Suppose:
- Working Capital = $150,000
- Bonding Multiplier = 10
Then:
Bonding Capacity = 150,000 × 10 = $1,500,000
You may qualify for bonded work up to $1.5 million in total value.
