Quick Answers
TL;DR: Enter product economics - Enter the product price and total cost, including shipping. These values set the gross margin and the starting point for break-even calculations.
Q: What is the difference between ROAS and ROI?A: ROAS (Return on Ad Spend) specifically measures revenue from advertising investment. ROI (Return on Investment) measures overall investment profit including all costs. Simply put, ROAS tells you how much revenue your ad spend generated, while ROI tells you if you're making an overall profit.
ROAS Calculator
Model revenue, profit, break-even ROAS, and max affordable CPA from your product economics and target ROAS
ROAS = Revenue / Ad Spend. Different categories have different ROAS standards, please adjust the target according to actual circumstances.
Your target ROAS is above break-even, so scaling can be reviewed with guardrails.
Tip: use the max affordable CPA as a stop-loss line before scaling. If actual CPA stays above it, pause scaling first.
Break-even ROAS is the critical point where advertising campaigns neither lose nor make money. When actual ROAS is higher than this value, campaigns start to be profitable.
When ROAS is above 0.0x, advertising campaigns start to be profitable
This is a planning scenario built from your inputs. It does not read ad-platform attribution, refunds, or actual order data. Compare it with your ad-platform and store reports before changing budget.
Use this calculator before changing budget when you want to see what a target ROAS implies for revenue, orders, profit, and CPA under your current product economics. It does not read campaign attribution data, so compare the scenario with actual ad-platform and store figures before acting.
Inputs
What to enter
Enter product price, total cost including shipping, ad spend, and target ROAS. You can also include a fee rate or discount in the scenario.
Outputs
What you get back
The calculator returns modeled revenue, order volume, gross and net margin, net profit, break-even ROAS, max affordable CPA, and a profit chart.
Formula
Core rule
Modeled revenue equals ad spend multiplied by target ROAS. Required orders equal modeled revenue divided by effective price. Break-even ROAS is derived from effective price, product cost, and any included fee.
Example
Example result
With an $80 product price, $32 total cost, $400 ad spend, and a 3.0 target ROAS, the model shows $1,200 revenue, $320 net profit, and about 1.7 break-even ROAS before optional fees or discounts.
Use it when
Best use cases
Use it for pre-budget scenario planning, product-margin checks, launch assumptions, and preparing guardrails for a weekly ad review.
Do not use it when
Limits
Do not treat the modeled revenue or profit as an observed campaign result. The tool does not ingest attribution, refunds, taxes, overhead, or actual order data, so reconcile those separately.

Enter product economics
Enter the product price and total cost, including shipping. These values set the gross margin and the starting point for break-even calculations.
Enter ad spend
Enter the amount of ad spend you want to model. The tool does not read campaign revenue or attribution data from an ad platform.
Set the scenario
Choose a target ROAS. If needed, include a fee rate or discount so the model reflects the selling conditions you want to test.
Review the modeled results
Read the modeled revenue, orders, margin, net profit, break-even ROAS, max affordable CPA, and profit chart. Compare the scenario with actual ad-platform and store reports before changing budget.
What is the difference between ROAS and ROI?
ROAS (Return on Ad Spend) specifically measures revenue from advertising investment. ROI (Return on Investment) measures overall investment profit including all costs. Simply put, ROAS tells you how much revenue your ad spend generated, while ROI tells you if you're making an overall profit.
What is a good ROAS value?
There is no universal good ROAS or fixed 2:1 break-even point. The threshold depends on product margin, fees, discount, refunds, and other costs. Use this calculator to estimate a break-even line from your own product economics.
How to calculate break-even ROAS?
Break-even ROAS = Sale Price / (Sale Price - all variable costs before advertising). For example, if product cost is 50% of the selling price, break-even ROAS is about 2:1. Below this means advertising loss, requiring strategy optimization or improving product margin.
How to set attribution window?
Set and document the attribution window in the ad platform or analytics system where campaign results are measured. This calculator does not import or configure attribution data; reconcile the modeled scenario with one consistent reporting window outside the tool.
Why does my ROAS fluctuate so much?
Observed ROAS can move with spend, conversion volume, offer changes, auction pressure, seasonality, refunds, and attribution. Compare the same scope and time window, then separate reporting changes from real business changes.
How to improve ROAS?
Start with the binding constraint: margin, conversion rate, average order value, CPA, creative quality, landing-page fit, or measurement. Change one controlled variable at a time and compare actual campaign and store data with the scenario guardrails.

Model profit and guardrails at a target ROAS
This calculator combines product price, total cost, ad spend, and a target ROAS to model revenue, orders, profit, break-even ROAS, and max affordable CPA. It does not import actual campaign results.
What it helps with
- - Connect product margin to a break-even ROAS
- - See the revenue and order volume implied by a target ROAS
- - Set a max CPA guardrail before reviewing a budget change
Practical outcomes
- - A clear planning scenario for the next budget review
- - A consistent set of profit and CPA guardrails
