Ad Budget Calculator
Budget Breakdown
Tip: Adjust your ROAS based on channel benchmarks. For e-commerce, a ROAS of 3-5 is common.
How to Use This Tool
Enter your sales goal, gross margin, target ROAS, and select your primary ad channel. Click "Calculate Budget" to see a detailed breakdown of your recommended ad spend, expected costs, revenue, and profit. Use "Reset" to clear all fields and start over.
Formula and Logic
The tool calculates your ad budget as: Ad Budget = (Sales Goal × Gross Margin) / Target ROAS. This ensures your ad spend is proportional to your profit margin and return goals. Expected ad spend equals the budget, target revenue is budget multiplied by ROAS, and profit after ads is target revenue times margin minus ad spend.
Practical Notes
For e-commerce, aim for a ROAS of 3-5 based on industry benchmarks. Adjust your margin if you have high fixed costs or trade terms. Consider seasonal trends and market competition when setting your sales goal. Always validate inputs to avoid unrealistic budgets.
