Outsourced vs In-House Services Cost Comparison Calculator
Compare the total annual cost of outsourcing a service versus building an in-house team to determine the most cost-effective option for your business.
Outsourced Service Costs
In-House Service Costs
Formulas Used
Outsourced Total Cost:
Annual Vendor Cost = Monthly Fee × 12
Annual Management Cost = Management Hours/Month × 12 × Manager Hourly Rate
Total Outsourced Cost = Setup Fee + (Annual Vendor Cost + Annual Management Cost + Annual Add-On Costs) × Contract Years
In-House Total Cost:
Annual Compensation per Employee = Annual Salary × (1 + Benefits Rate / 100)
Total Annual Compensation = Annual Compensation per Employee × Number of Employees
Total Annual Recurring = (Training + Software + Overhead) per Employee × Number of Employees
Total One-Time Costs = (Recruiting + Equipment) per Employee × Number of Employees
Total In-House Cost = Total One-Time Costs + (Total Annual Compensation + Total Annual Recurring) × Contract Years
Savings = |Total In-House Cost − Total Outsourced Cost|
Savings % = Savings / max(Total Outsourced, Total In-House) × 100
