Incremental Sales from Advertising measures the additional sales generated directly as a result of advertising efforts, beyond what would have occurred without the ads.
How to Calculate Incremental Sales from Advertising
Identify the sales lift caused by advertising by comparing actual sales to a baseline or control group.
- Establish baseline sales: Determine expected sales without advertising (e.g., historical or control group data).
- Measure actual sales: Track sales during the advertising period.
- Calculate incremental sales: Subtract baseline sales from actual sales.
- Analyze ROI: Compare incremental sales revenue to advertising spend.
Formula example: Incremental Sales = Actual Sales – Baseline Sales
