## Quick Answer
Break-even ROAS is the point where order contribution before ads is exactly consumed by ad spend. If contribution before ads is 40% of revenue, the break-even ROAS is 2.50x before overhead and profit.

## Use When
Use Break-Even ROAS Calculator when a store decision needs a clear next step instead of a vague note.

## Output
A plain-language result, practical caveats, and follow-up actions the team can save or share.

## Inputs
- Average order value
- Product cost
- Shipping and fulfillment cost
- Payment/platform fees

## Method
Enter one product group or one representative blended order at a time. The calculator subtracts product cost, shipping, fulfillment, and fees from revenue, then converts the remaining contribution into a ROAS floor.

## Limits
The result excludes returns, fixed overhead, creative production, agency fees, inventory financing, and payback timing. Add those before using the result as a scaling target.

## Why this matters in a real store
Break-Even ROAS Calculator matters because ecommerce growth work usually breaks down in the handoff between a number, a platform warning, a campaign idea, and the person who has to make the next decision. A store team may know something is wrong, but still lose time because the issue is not written in a way that connects the symptom to a next action.

Use this page as a practical translation layer. The goal is to slow down the first reaction, name the business risk, and give the team enough context to decide whether the next move is a calculation, a feed change, a campaign QA step, or a page update. The tables and checklists are there to make the work repeatable, but the judgment comes from understanding why the issue appears in the first place.

## The formula behind the calculator
Break-even ROAS is revenue divided by contribution before ad spend. Contribution before ad spend is the money left after product cost, fulfillment, shipping, payment fees, and other order-level variable costs.
Worked example: If an order is $100, product cost is $40, shipping is $10, and fees are $5, contribution before ads is $45. Break-even ROAS is $100 / $45 = 2.22x. Spend more than $45 to acquire that order and the order is negative before overhead.

## Why platform ROAS can mislead you
Ad platforms report revenue divided by ad spend. They usually do not know your landed product cost, returns, payment fees, warehouse cost, creative cost, or overhead. A 3x ROAS can be excellent for a high-margin digital product and poor for a low-margin physical product.
Input | Why it changes ROAS floor
Product cost | Higher cost lowers contribution and raises the ROAS needed to break even.
Shipping and fulfillment | Free shipping offers can turn a profitable order into a break-even order.
Payment and platform fees | Small fees matter when margin is already tight.
Returns | Not in the simple calculator, but should be added to the decision before scaling.

## How to use the result
Calculate break-even ROAS for your actual blended order economics.
Set your platform target above break-even if you need room for overhead and profit.
Compare by product category, not just store average.
Recalculate after price changes, shipping promos, new fees, or supplier cost changes.

## Common ROAS floor mistakes
Mistake | Why it hurts
Using revenue margin instead of contribution | It ignores shipping, fulfillment, and payment fees.
Using the same target for all products | It hides weak-margin products inside a blended average.
Ignoring discounts | A sale can raise conversion while pushing the ROAS floor higher.
Forgetting return allowance | Returned orders can make an apparently profitable target too low.

## Common Questions
### Is break-even ROAS the target I should set in ads?
No. It is the floor. A real target usually needs room for overhead, returns, cash timing, and profit.

### Why can two products need different ROAS?
Products with different cost, shipping weight, return rate, or discount behavior have different contribution margins, so their ROAS floors differ.

### Should I use store average AOV?
Only for a blended planning pass. For budget decisions, calculate separate floors for major product groups and offer types.
