# ROAS Calculator

- **URL:** https://codeasystem.com/calculators/marketing/roas-calculator/
- **Category:** marketing
- **Description:** Measure return on ad spend as a revenue multiple, with profit over spend and a breakeven verdict included.
- **Primary output:** Return on ad spend: 3×

## Inputs
- Attributed revenue (name: `revenue`, type: number, prefix: $, example: 12000)
- Ad spend (name: `spend`, type: number, prefix: $, example: 4000)

## Outputs
- Return on ad spend: 3×
- Profit over ad spend: $8,000.00
- Verdict: Above the 1× breakeven; ads paid for themselves before other costs

## Formula / methodology
```
ROAS = attributed revenue ÷ ad spend
Profit over spend = revenue − spend     Breakeven at ROAS = 1×
```

ROAS divides the revenue your platform attributes to advertising by what that advertising cost, expressing the result as a multiple. Anything above 1× covers the ad bill itself; true profit requires margins to absorb product costs and overhead too.

## Assumptions & limitations
- Attribution follows your platform’s model; last-click numbers undercount upper-funnel work.
- Revenue excludes refunds and chargebacks unless netted first.
- Compares one campaign, channel or period consistently.

## How to use
1. **Pull attributed revenue**; Use the same attribution window your team plans against, applied consistently week to week.
2. **Enter the true ad spend**; Include management fees and creative production if you want the honest number.
3. **Read against breakeven**; 1× means the ads paid for themselves only; most businesses need roughly 3×+ to be genuinely profitable.

## Example
Generating $12,000 of attributed revenue from $4,000 of ads is a 3× ROAS; $8,000 of profit over ad spend before other costs.

Result for these inputs:

```
Return on ad spend: 3×
```

## About this calculator
### ROAS versus ROI

ROI divides profit by cost; ROAS divides revenue by ad cost. They diverge sharply once margins thin out; a 2× ROAS on a 30% margin business actually loses money. Know which question you are asking.

### Breakeven ROAS is a margin calculation

Your true breakeven equals 1 ÷ gross margin. At a 60% margin you need about 1.67× just to break even; at 25% margins you need 4×. Every ROAS target should start from that arithmetic.

### Attribution shapes everything

Platforms credit themselves generously. Triangulate with blended metrics; overall revenue growth against total spend; before scaling budgets on platform-reported ROAS alone.

## FAQs
### What ROAS is considered good?

It depends on margins. Common guidance calls 4× strong for ecommerce, but a high-margin software firm may thrive at 2× while a low-margin reseller needs 6×.

### Should I include agency fees in spend?

For internal truthfulness yes; fully loaded spend reveals whether campaigns survive real costs. Many teams track both figures.

### Can ROAS be negative?

No; the ratio bottoms at 0× when revenue is zero. The profit row can be negative though, showing exactly how much money the ads burned.
