Marketing Agency vs In-House Cost Calculator

The Marketing Agency vs In-House Cost Calculator is a free online tool that helps businesses compare the total cost of ownership between hiring a marketing agency and building an in-house marketing team.

• Calculates salaries, employer NI, pensions, benefits, recruitment, training, tools, management overhead, and office space for in-house teams.
• Compares against agency monthly retainer fees and included services.
• Provides annual savings potential, break-even analysis, team size comparison, and personalised recommendations.
• Designed for marketing directors, CFOs, CEOs, and growing SMEs evaluating marketing structure decisions.

By revealing hidden costs such as employer National Insurance (13.8%) and recruitment fees, the calculator enables data‑driven decisions that can save tens of thousands of pounds annually.
