Break-Even ROAS Calculator for Profitable Ad Campaigns

What This Break Even ROAS Calculator Does

This calculator helps you find the minimum ROAS you must hit to avoid losing money on paid ads. It takes your revenue per purchase and subtracts all per-order costs (COGS, shipping, transaction fees, and other costs). The remaining amount is your maximum break-even ad spend per purchase. From there, it converts that into a Break Even ROAS threshold.

If your total costs are equal to or higher than your revenue, your unit profit is zero or negative. In that situation, Break Even ROAS becomes infinite because no positive ad spend can be profitable until you fix your unit economics.

How to Calculate Break-Even ROAS Step by Step

1. Enter Revenue per product: Use your selling price after discounts. If you usually sell bundles or get multiple items per order, use your Average Order Value instead of a single item price.
2. Enter costs per product: Add every cost that happens per purchase (COGS, shipping/fulfillment, payment processing fees, packaging, app fees, pick & pack, etc.).
3. Select VAT for each line: Enter your amounts including VAT and choose the VAT rate. The calculator removes VAT to work with net values.
4. Read the result: Any campaign/ad set/ad with ROAS above your Break Even ROAS is profitable (before overhead). Anything below it is losing money.

Why is Break Even ROAS So Important?

Facebook, TikTok, and Snapchat all report the ROAS (Return on Ad Spend) for every campaign, ad set/ad group, and individual ad. This allows you to track how effective each part of your online advertising campaign is at all levels.

A ROAS of 1 means you are spending exactly the same amount of money as you are earning from conversions. If you spend $10 to sell a $10 product, the platform will show a ROAS of 1. Simply put, this means you break even.

However, you must also take other costs into account. Cost of goods, shipping costs, transaction costs, VAT, and other expenses all eat into your margins. This is where the Break Even ROAS becomes essential.

What is the Break Even ROAS?

With a Break Even ROAS, you know exactly what ROAS you need for your ads to break even after accounting for all costs.

For example, if your Break Even ROAS is 1.8, you can check your Facebook, TikTok, or Snapchat campaigns and instantly see which ones are profitable:

• ROAS higher than 1.8 = Profitable
• ROAS lower than 1.8 = Losing money
• ROAS exactly 1.8 = Breaking even

The Break Even ROAS Formula

First, add up all your costs together. Then use this formula to calculate the ROAS at which a campaign, ad set, or ad becomes profitable:

Example Calculation

Suppose you sell a product for $30, cost of goods are $8, and shipping costs are $2:

This means that for every campaign, ad set, or ad that has a ROAS higher than 1.5, you make a profit!

How to Apply Break Even ROAS in Real Ad Accounts

Break Even ROAS is best used as a hard guardrail for decision-making. Once you know your number, you can set clear rules:

• Pause: If ROAS stays below break-even after enough data, stop spending.
• Hold: If ROAS is near break-even, optimize creatives, landing page, and offer before scaling.
• Scale: If ROAS is safely above break-even, increase budget gradually and watch for efficiency drop.

In practice, you usually want a buffer. A common target is 20–30% above break-even to cover overhead, returns, and normal performance fluctuation.

What to Include (So the Number Is Actually Useful)

• Use net values: If your platform reports revenue excluding tax, use net inputs. If you enter gross amounts, set VAT so the calculator can remove it.
• Include payment fees: Stripe/PayPal fees and any per-transaction costs.
• Include fulfillment reality: Pick/pack, packaging, shipping surcharges, and carrier fees.
• Handle returns: If returns are common, reduce effective revenue (e.g., multiply by 1 - return rate) or add an expected return cost per order.
• Don’t mix overhead: Rent and salaries are real, but keep this calculator focused on per-order costs. Add overhead later as an extra buffer.

Tips for Using Your Break Even ROAS

• Set Target ROAS: Aim for 20-30% above your break-even point for healthy profits
• Pause Underperformers: Turn off ads with ROAS below your break-even threshold
• Scale Winners: Increase budget on ads significantly above break-even
• Include All Costs: Do not forget transaction fees, returns, and packaging
• Account for VAT: Use our calculator to properly exclude VAT from your calculations
