Frequently Asked Questions

How do you calculate required Facebook ad spend?

Required Ad Spend = (Target Revenue / AOV / Conversion Rate / CTR) / 1000 * CPM. In plain terms, you calculate how many orders you need, how much website traffic is required to produce those orders, and the advertising cost to generate that traffic based on current CPM and CTR rates.

What is break-even ROAS and why is it crucial?

Break-even ROAS is the minimum Return on Ad Spend required to cover both product costs (COGS) and ad spend without losing money. The formula is 1 / Gross Margin Percentage. For example, if your product has a 50% gross margin, your break-even ROAS is 1 / 0.50 = 2.0x.

What is a good CTR for Facebook ads?

Across e-commerce and retail, an average link click-through rate (CTR) on Facebook is around 1.0% to 1.5%. High-performing creatives with compelling hooks can achieve 2.0% to 4.0%+ CTRs, which dramatically reduces your Cost Per Click (CPC).

How does Average Order Value (AOV) impact ad profitability?

Higher AOV gives you significantly more margin to bid aggressively in the ad auctions. Increasing your AOV by 25% through product bundles or post-purchase upsells directly lowers your required break-even ROAS, allowing you to acquire customers profitably even as CPM costs rise.
