IT Staff Augmentation vs. Outsourcing Cost Comparison Calculator

Compare the true total cost of bringing in augmented IT staff versus outsourcing your IT project or function to a managed service provider.

### Staff Augmentation Inputs

Number of Augmented Resources

Hourly Bill Rate per Resource (USD)

Hours per Week per Resource

Engagement Duration (Weeks)

One-Time Onboarding & Training Cost (USD)

Internal Management Overhead (% of labor cost)

Tooling / License Cost for Period (USD)

### Outsourcing Inputs

Fixed Contract Fee for Period (USD)

Estimated Variable / Overage Costs (USD)

Transition & Knowledge Transfer Cost (USD)

Vendor Management Overhead (% of contract fee)

Risk / Contingency Buffer (% of total outsourcing cost)

#### Formulas Used

Staff Augmentation Total Cost:

Outsourcing Total Cost:

Savings = Total Outsourcing Cost − Total Augmentation Cost (positive = augmentation is cheaper)

Savings % = (Savings ÷ Total Outsourcing Cost) × 100
