Assess Advertising Profitability with Precision

The challenge for any growing business is knowing if money spent on advertising actually generates profit. Many companies struggle to connect their media spend (ad cost) directly to the long-term revenue generated, leading to inefficient spending and guesswork in scaling campaigns.

Our MCP provides a structured mechanism to bridge this financial intelligence gap by running three sequential, interconnected calculations:

  1. Calculate Total ROAS: We start by using calculate_roas. You input your total media spend and the attributed revenue. This tool calculates the overall Return on Ad Spend (ROAS) and can provide a detailed breakdown by specific channels or individual campaigns.
  2. Benchmark Performance: Next, we use get_target_benchmark to establish an industry-standard floor. By specifying your business type (e.g., E-commerce, SaaS), the tool returns the minimum required ROAS benchmark, ensuring you measure performance against best practices.
  3. Determine Break-Even Point: Finally, using calculate_break_even_roas, you input your contribution margin percentage. This calculates the absolute minimum ROAS needed just to cover all marginal costs associated with ad spend, giving you a safety net threshold.

The result is not just a number; it's an actionable blueprint for financial health. By systematically linking what was spent (calculate_roas), what should have been achieved (get_target_benchmark), and the minimum sustainable performance level (calculate_break_even_roas), you can immediately determine if your marketing spend supports profitable growth.

We spent $15,000 last month and generated $60,000 in revenue. Can you calculate the total ROAS and break down the performance by 'Google Ads' vs 'Facebook/Instagram'?

Calling `calculate_roas` with mediaSpend=15000, sourceRevenue=60000, and groupByField='Channel'. The total ROAS is 4.0x. Google Ads contributed a ROAS of X, while Facebook/Instagram contributed Y.

We are an E-commerce company reporting in USD. What is the minimum target ROAS we should aim for?

Calling `get_target_benchmark` with businessType='E-commerce' and targetCurrencyCode='USD'. The system returns a benchmark of 4x, which serves as your minimum performance goal.

Our current contribution margin is 0.55 (55%). What ROAS do we need to break even in EUR?

Calling `calculate_break_even_roas` with contributionMarginPercentage=0.55 and targetCurrencyCode='EUR'. The required break-even ROAS is 1.82x, meaning your ad spend must generate at least this much revenue to cover all marginal costs.

You can use `calculate_roas` to get both. By providing a 'groupByField' (like Channel), the tool calculates the total ROAS across all inputs, but also provides granular performance metrics for each distinct channel or campaign group.
