Break-Even Ad Spend Calculator FAQ
- What is the difference between Break-Even ROAS and Target ROAS?
- Break-Even ROAS (2.13 in the example) is the minimum return needed to cover all costs and reach your profit margin goal. Target ROAS (3.70 in the example) is the higher return you aim for to achieve your desired net profit after all expenses.
- How does Returns/Refunds Rate affect the calculation?
- The returns percentage reduces your effective revenue per order. A 10% return rate means only 90% of purchased units generate full revenue, which raises the break-even ROAS and maximum CPA required to remain profitable.
- Can I use this calculator if I don't know my exact COGS?
- Yes, you can use industry averages or estimates for shipping and fulfillment, but accuracy improves with your actual per-order costs. The tool notes that most DTC brands see 20-60% of AOV as COGS.
- What does Current ROAS input actually do?
- Entering your actual ROAS from existing campaigns shows your current profit per order and profit margin. This lets you compare your performance against the break-even point and see how much profit you're gaining or losing at your current spend level.
