Find the exact minimum ROAS required to cover your costs based on your contribution margin.
Margin Inputs
Live CalculationPercentage of revenue remaining after subtracting direct variable costs (construction, delivery, sales commissions).
Minimum Break-Even ROAS Floor
You must achieve at least 2.50× in advertising ROAS to avoid financial loss at a 40% contribution margin.
The Profitability Rule:
When your actual ROAS exceeds this Break-Even threshold, campaigns generate net contribution profit. When below, you lose money on every deal.
Break-Even ROAS = 1 / (Contribution Margin % / 100)
Contribution Margin %: The percentage of revenue remaining after subtracting direct variable costs (e.g. land, construction, delivery, direct sales broker fees).
Break-Even ROAS Formula: 1 / (Contribution Margin % / 100). For example, a 25% margin requires 1 / 0.25 = 4.00× ROAS to avoid losing money.
Break-Even ROAS represents your profitability baseline. If your campaigns perform above this threshold, you generate net contribution profit. If your ROAS falls below this number, you are actively losing capital on every sale.
Many media buyers celebrate a 3.0× ROAS without realizing that with a 20% contribution margin (which requires a 5.0× Break-Even ROAS), their campaigns are losing 40% on every closed customer.
Use this metric to set hard target floors for your performance marketing and agency media buying contracts.
A real estate developer in Cairo operates with a 33.3% gross contribution margin after construction, land allocation, and brokerage payouts.
Any advertising campaign achieving greater than 3.0× ROAS generates positive net contribution profit for the development.
