What ROAS do you actually need?

Load a niche preset or enter your own numbers. The breakeven ROAS is set entirely by your margin — then use the planner to see whether your expected ROAS and ad budget actually turn a profit.

*Contribution after ad spend, before fixed overhead (apps, salaries). At the budget & ROAS you entered.

Rule of thumb: take your breakeven ROAS and add a 0.5×–1.0× buffer to set a realistic target. If your campaigns can't clear breakeven, the fix is margin (price, COGS, returns) — not more budget.
Breakeven ROAS by niche

The bar you have to clear, by category

Same calculation applied to typical unit economics for each niche. The lower the breakeven ROAS, the easier paid acquisition scales — because margin, not demand, sets the bar.

The math nobody runs first

Your breakeven ROAS is decided before you run a single ad

It isn't a media-buying number — it's a margin number. The formula is simple:
Breakeven ROAS = 1 ÷ Contribution Margin %
A product with a 50% contribution margin needs a 2× ROAS to break even. At 25% margin, you need 4×. The average ecommerce store runs a 2.87× ROAS (median just 2.04×) — so a thin-margin product needing 4×+ is fighting the averages every single day. A high-margin product needing 1.7× has enormous room before it loses money.This is why niche and margin choices are really ad-efficiency choices. Generic dropshipping at 15–25% margins needs a 4–7× ROAS while paying a $68–84 customer acquisition cost. Private-label jewelry at 60–80% margins clears breakeven at under 2×. Same ad platforms, completely different odds.

FAQ

What is breakeven ROAS and how do you calculate it?
Breakeven ROAS is the return on ad spend at which your ad-driven sales exactly cover their costs — no profit, no loss. The formula is 1 ÷ your contribution margin percentage, where contribution margin is revenue minus all variable costs except ads (product, shipping, fees, returns). A 40% contribution margin gives a breakeven ROAS of 2.5×; a 60% margin gives about 1.67×. Anything above your breakeven ROAS is profit; anything below is a loss.
What is a good ROAS for ecommerce in 2026?
There's no universal “good” number — it depends entirely on your margin. The average ecommerce ROAS is about 2.87× with a median near 2.04×, and channel targets often cited are 3.5–4.5× on Meta and 4–5× on Google Shopping. But the only target that matters is yours: calculate your breakeven ROAS, then add a 0.5×–1.0× buffer for a realistic, profitable goal. A 60%-margin product profits at a ROAS that would bankrupt a 20%-margin one.
How much should I spend on ads to acquire a customer?
Your maximum cost per acquisition (CPA) at breakeven equals your contribution margin per order — the dollars left after product, shipping, fees, and returns. Spend more than that and you lose money on each sale. To hit a target profit margin, subtract that profit from your contribution margin first; the remainder is your max CPA. This calculator shows both the breakeven and target CPA for your numbers.
Why is my breakeven ROAS so high?
A high breakeven ROAS means a thin contribution margin. The usual culprits are a low price relative to cost, expensive shipping, high platform/payment fees, or a high return rate. Because breakeven ROAS is 1 ÷ contribution margin, even small margin improvements lower the bar fast — raising margin from 20% to 30% drops your breakeven ROAS from 5× to 3.3×. Fix margin before adding ad budget.
Does a higher AOV lower my breakeven ROAS?
Only if it improves your contribution margin percentage. Raising AOV through bundling or upsells usually does, because fixed per-order costs (like shipping and transaction fees) spread across more revenue. Breakeven ROAS tracks margin percentage, not order size — but in practice a higher AOV and a leaner cost structure tend to move together, which is why AOV is one of the highest-leverage levers on ad efficiency.
