## Overview

This calculator measures how efficiently your ad spend converts into revenue. Enter what you spent on ads, the revenue those ads generated, and your gross margin to instantly see your ROAS ratio, whether you are above or below the break-even threshold, and your actual gross profit. Use the target revenue field to find out exactly how much you need to spend to hit a revenue goal at your current efficiency.

## How to read your result

The headline ROAS ratio tells you how many units of revenue you earn per unit of ad spend — a ROAS of 4 means every 1 spent on ads returned 4 in revenue. Below that, the break-even ROAS shows the minimum ratio your campaign must reach to cover product costs; anything above it is profitable, anything below is a loss. Gross profit applies your margin to the revenue and subtracts the ad spend, giving you the real dollar gain or loss from the campaign. The break-even line chart shows how the revenue needed to break even scales as your spend increases.

## Method

ROAS is calculated as ad revenue divided by ad spend. Break-even ROAS is derived from gross margin: break-even ROAS = 1 divided by (gross margin as a decimal), following the standard formula used by digital marketing practitioners (see Improvado and Shopify references). Gross profit equals ad revenue multiplied by the gross margin percentage minus ad spend. The spend required to hit a target is computed by dividing the target revenue by the current ROAS. The break-even series plots nine evenly-spaced spend points from zero to twice the entered ad spend (minimum upper bound 1,000), with the corresponding revenue that would be needed to break even at each spend level.

## Example

- **Setup:** Ad spend: 500. Ad revenue: 2,000. Gross margin: 40%. Target revenue: 5,000.
- **Result:** ROAS is 4 (2,000 ÷ 500). Break-even ROAS is 2.5 (1 ÷ 0.40). Because 4 exceeds 2.5 the campaign is profitable. Gross profit is 300 (2,000 × 0.40 − 500). To reach 5,000 in revenue at the current ROAS of 4 you need to spend 1,250.

## Frequently asked questions

### What is ROAS and how is it different from ROI?

ROAS (return on ad spend) is a ratio of ad revenue to ad spend: ROAS = revenue ÷ ad spend. It measures the raw revenue efficiency of a campaign. ROI (return on investment) goes further by subtracting all costs — including the cost of goods — from revenue before dividing by total investment. A high ROAS can still produce a negative ROI if product margins are thin, which is why break-even ROAS matters.

### How is the break-even ROAS calculated?

Break-even ROAS = 1 ÷ gross margin (as a decimal). At a 40% gross margin the break-even ROAS is 1 ÷ 0.40 = 2.5. That means every 1 spent on ads must return at least 2.5 in revenue before ad costs for the campaign to cover the cost of goods. A lower margin raises the break-even ROAS, leaving less room for error.

### Why does gross margin matter so much for paid advertising?

Gross margin determines how much of each revenue unit is left to cover ad spend. At 25% margin you keep only 0.25 per 1 of revenue, so your break-even ROAS is 4 — a demanding target. At 60% margin you keep 0.60, so break-even ROAS drops to about 1.67. Knowing your margin before setting bid targets prevents campaigns that look profitable on a revenue basis but lose money in practice.

### What counts as good ROAS?

There is no universal benchmark because the right ROAS depends on your gross margin, customer lifetime value, and channel costs. A common rule of thumb for e-commerce is a ROAS of 4 or higher, but a subscription business with high lifetime value might run profitably at ROAS 1.5. Always compare your ROAS to your break-even ROAS — not to industry averages — to know whether a campaign is truly generating profit.

### How do I use the target revenue field?

Enter the revenue amount you want to reach in a period. The calculator divides that target by your current ROAS to tell you the ad spend required. This is useful for media planning: if your current ROAS is 4 and you want 20,000 in revenue, you need to budget 5,000 in ad spend, assuming your efficiency stays constant. Adjust the ad spend or margin fields to explore different scenarios.
