Use this tool to quantify the potential profit you missed by choosing one PPC strategy (the Chosen Investment) over its best available alternative (the Forgone Option). Understanding this cost is crucial for optimizing future campaign spending.

Calculated Opportunity Cost:
PPC Opportunity Cost Formula
Net Profit (NP) = (Conversions × Revenue Per Conversion) – Spend
Opportunity Cost (OC) = NP of Forgone Option - NP of Chosen Strategy
Variables Used in the Calculator
- Monthly PPC Spend: The total budget allocated to the PPC campaign per month.
- Revenue Per Conversion (RPC): The average dollar value generated from a single conversion (e.g., a sale or qualified lead).
- Monthly Conversions: The total number of successful conversions achieved during the month.
- Chosen Strategy (CI): The PPC campaign or investment path that was ultimately selected.
- Forgone Option (FO): The best alternative PPC campaign or investment that was not selected.
What is PPC Opportunity Cost?
Opportunity Cost in the context of Pay-Per-Click (PPC) advertising is the potential benefit or profit that a business loses out on when choosing one specific campaign or spending strategy over another. Unlike sunk costs, which are expenses already incurred, opportunity cost is entirely forward-looking and focuses on *what could have been*.
For a marketing manager, calculating this cost is a critical part of campaign review. If Campaign A was chosen, but Campaign B was the best alternative, the opportunity cost is the difference in net profit between B and A. A positive opportunity cost means the forgone option was financially superior, signaling a need to revise future budget allocation. A negative cost suggests the chosen strategy was indeed the most profitable.
How to Calculate PPC Opportunity Cost (Example)
Let’s use a step-by-step example based on the formulas above:
- Define Strategies:
- Chosen Strategy (CI): Spend = $10,000, RPC = $50, Conversions = 450.
- Forgone Option (FO): Spend = $9,000, RPC = $60, Conversions = 400.
- Calculate Net Profit for CI:
NP_CI = (450 × $50) – $10,000 = $22,500 – $10,000 = $12,500
- Calculate Net Profit for FO:
NP_FO = (400 × $60) – $9,000 = $24,000 – $9,000 = $15,000
- Determine Opportunity Cost:
OC = NP_FO – NP_CI = $15,000 – $12,500 = $2,500
- Result Interpretation: The opportunity cost is $2,500. By choosing the CI strategy, the company forfeited $2,500 in potential net profit that could have been gained by running the FO strategy instead.
Frequently Asked Questions (FAQ)
- When is the Opportunity Cost considered negative?
The opportunity cost is negative when the Net Profit of the Chosen Strategy (CI) is higher than the Net Profit of the Forgone Option (FO). This indicates that the chosen investment was the superior financial decision.
- Does Opportunity Cost include ad creative or labor costs?
Yes. Ideally, the “Monthly PPC Spend” input should include *all* relevant costs, including platform spend, creative development fees, and management time, to calculate the true net profit for each option.
- Why is this calculation important for SEO?
Understanding opportunity cost helps identify the most efficient channels for traffic and revenue. If a PPC strategy consistently underperforms compared to a high-ranking SEO strategy, the opportunity cost of not investing more in SEO becomes quantifiable.
- What are examples of forgone options in PPC?
A forgone option could be using a different bidding strategy (e.g., Maximize Conversions instead of Target ROAS), targeting a different demographic, allocating the budget to a different platform (e.g., Microsoft Ads instead of Google Ads), or investing the money outside of PPC entirely (e.g., content marketing).
