Ads & ROAS Profit Calculator Guide

Use the live tool: Ads & ROAS Profit Calculator

Running ads can feel straightforward when the dashboard shows a respectable ROAS number. But ROAS on its own does not tell you whether the campaign is actually making money after product cost, fees, and shipping.

This guide explains how to use the Ads & ROAS Profit Calculator to answer three practical questions:

  • Is my current ROAS actually profitable?
  • What is my break-even ROAS based on margin before ads?
  • What target ROAS and max CPC can I afford for future campaigns?

What this calculator actually does

This tool works as a break-even ROAS calculator for ecommerce, an ads and ROAS profit calculator for Etsy and Shopify sellers, and a simple planner for future campaigns.

It shows you:

  • gross profit per order before ads,
  • gross margin before ads,
  • break-even ROAS,
  • actual ROAS for an existing campaign,
  • profit after ads,
  • and, in planning mode, the target ROAS, max ad spend per order, and max CPC your margins can support.

That makes it more useful than looking at ad platform numbers in isolation.

Key ideas to understand first

Before you use the calculator, it helps to keep four ideas clear.

1. ROAS

ROAS means return on ad spend:

ROAS=revenue from adsad spend\text{ROAS} = \frac{\text{revenue from ads}}{\text{ad spend}}

If you spend $100 and generate $300 in tracked ad revenue, ROAS is 3.0.

2. Gross profit before ads

This is the profit you make on an order before any ad spend is applied.

Gross Profit Before Ads=AOV−non-ad order costs\text{Gross Profit Before Ads} = \text{AOV} - \text{non-ad order costs}

Those non-ad costs usually include:

  • product cost,
  • marketplace or platform fees,
  • payment fees,
  • fixed transaction fees,
  • and shipping contribution.

3. Gross margin before ads

Gross Margin Before Ads=gross profit before adsaverage order value\text{Gross Margin Before Ads} = \frac{\text{gross profit before ads}}{\text{average order value}}

This is the number that drives break-even ROAS.

4. Break-even ROAS

Break-even ROAS=1gross margin before ads\text{Break-even ROAS} = \frac{1}{\text{gross margin before ads}}

If margin before ads is thin, break-even ROAS gets much higher. That is why a ROAS that looks "good" on the surface can still lose money.

How to use the Ads & ROAS Profit Calculator

Shared order economics inputs

Both modes use the same basic product economics.

  • Average order value (AOV): the average revenue per order from these ads, or the typical order value you expect.
  • Product cost per order: total item cost for one order.
  • Platform fee %: for Etsy, Amazon, Shopify apps, or marketplace commission.
  • Payment fee % and fixed fee: card or payment processor costs.
  • Shipping charged and shipping cost: so the calculator can include shipping contribution properly.

These numbers tell you how much margin exists before ads enter the picture.

Mode A: Analyse existing campaign

Use this mode when you already have campaign data.

Add:

  • Ad spend for the period
  • Revenue from these ads in this period

If you do not have direct ad revenue handy, you can enter:

  • Orders from ads

In that case, the calculator estimates revenue as:

Revenue From Ads=Orders From Ads×AOV\text{Revenue From Ads} = \text{Orders From Ads} \times \text{AOV}

This mode is best for questions like:

  • Is my ROAS profitable or losing money?
  • Should I keep this Meta or Google Ads campaign running?
  • Are Etsy Ads worth it for this product?

Mode B: Plan a new campaign

Use this mode when you want targets before you spend money.

Add:

  • Expected conversion rate from click to order
  • Target ROAS if you already have one

If you leave target ROAS blank, the calculator suggests one based on break-even ROAS:

Suggested Target ROAS=Break-even ROAS×1.3\text{Suggested Target ROAS} = \text{Break-even ROAS} \times 1.3

That gives you a practical buffer above break-even instead of aiming too low.

How the core maths works

Step 1: Calculate order economics before ads

Variable fees per order:

Variable Fees Per Order=(platform fee rate+payment fee rate)×AOV\text{Variable Fees Per Order} = (\text{platform fee rate} + \text{payment fee rate}) \times \text{AOV}

Shipping net:

Shipping Net=Shipping Charged−Shipping Cost\text{Shipping Net} = \text{Shipping Charged} - \text{Shipping Cost}

Total non-ad costs:

Total Costs Before Ads=COGS+Variable Fees+Fixed Fee−Shipping Net\text{Total Costs Before Ads} = \text{COGS} + \text{Variable Fees} + \text{Fixed Fee} - \text{Shipping Net}

Gross profit before ads:

Gross Profit Before Ads=AOV−Total Costs Before Ads\text{Gross Profit Before Ads} = \text{AOV} - \text{Total Costs Before Ads}

Step 2: Turn margin into break-even ROAS

Once gross margin before ads is known:

Break-even ROAS=1Gross Margin Before Ads\text{Break-even ROAS} = \frac{1}{\text{Gross Margin Before Ads}}

If gross margin before ads is 40%, then:

Break-even ROAS=10.40=2.5\text{Break-even ROAS} = \frac{1}{0.40} = 2.5

That means the campaign needs at least $2.50 in revenue for every $1.00 spent just to break even.

Step 3: Compare actual ROAS with break-even ROAS

In analysis mode:

Actual ROAS=Revenue From AdsAd Spend\text{Actual ROAS} = \frac{\text{Revenue From Ads}}{\text{Ad Spend}}

Then compare:

  • if actual ROAS is below break-even ROAS, the campaign is losing money,
  • if it is roughly equal, the campaign is near breakeven,
  • if it is above break-even ROAS, the campaign is profitable.

Step 4: Calculate max ad spend per order and max CPC

In planning mode:

Max Ad Spend Per Order=AOVTarget ROAS\text{Max Ad Spend Per Order} = \frac{\text{AOV}}{\text{Target ROAS}}

Then:

Max CPC=Max Ad Spend Per Order×Conversion Rate\text{Max CPC} = \text{Max Ad Spend Per Order} \times \text{Conversion Rate}

This is the simplest answer to how to calculate target ROAS from profit margin and max CPC calculator from ROAS and conversion rate.

What the results mean

Analyse existing campaign

This mode shows:

  • gross margin before ads,
  • break-even ROAS,
  • actual ROAS,
  • gross profit from orders before ads,
  • profit after ads,
  • and ad ROI.

The most important line is the status message:

  • below break-even means the campaign is losing money,
  • roughly breakeven means it is close to zero profit,
  • above break-even means it is profitable.

Plan a new campaign

This mode shows:

  • gross margin before ads,
  • break-even ROAS,
  • target ROAS,
  • max ad spend per order,
  • profit per order after ads at that target,
  • and max CPC at your expected conversion rate.

This is especially useful when you are asking:

  • What ROAS should I aim for on Google Ads?
  • What max CPC can I afford for this product?
  • Can I afford ads on Etsy or Shopify with this margin?

Practical use cases

This calculator is especially useful when:

  • you are checking a live Meta or Google Ads campaign,
  • you are deciding whether Etsy Ads are worth it for a handmade product,
  • you want a clearer answer to "is my ROAS profitable or losing money",
  • you need a max CPC before launching paid traffic for a new product,
  • or you want to compare products with very different margins before choosing which one to advertise.

Common mistakes this calculator helps avoid

Looking only at ROAS and ignoring margin

A campaign can show a decent ROAS and still lose money if the order margin is weak before ads.

Ignoring fees and shipping

Marketplace fees, payment fees, and shipping often shrink margin more than sellers expect. If those are left out, break-even ROAS looks easier than reality.

Setting a target ROAS with no link to order economics

Many sellers pick a target like 2.0 or 3.0 just because it sounds familiar. This calculator links target ROAS back to your actual order margin so the number is grounded in reality.
