# The ROAS calculator that knows your margin.

Return on ad spend means nothing without break-even context. Enter spend, revenue, and gross margin — see your ROAS, the ROAS you actually need, and whether the campaign made money.

Ad spend

Total cost of the campaign

Revenue from ads

Revenue those ads drove

Gross margin %

Used for break-even ROAS

Your ROAS — Enter spend and revenue Break-even ROAS 2.00x Required at 50% margin Profit after ad spend — Gross profit minus spend

Formulas: ROAS = revenue ÷ spend. Break-even ROAS = 1 ÷ gross margin. Profit = revenue × margin − spend. All math runs in your browser — nothing is stored or sent anywhere.

The numbers

## What your ROAS is actually telling you.

### What is ROAS?

ROAS (return on ad spend) measures the revenue your advertising generates for every dollar it costs: revenue from ads ÷ ad spend. Spend $5,000 to drive $20,000 and your ROAS is 4.0x — every ad dollar returned four dollars of revenue.

### Why break-even ROAS matters more

Revenue is not profit. Break-even ROAS — 1 ÷ gross margin — is the return where a campaign stops losing money. At a 50% margin you need 2.0x just to break even; at a 25% margin you need 4.0x, and that “strong” 4x campaign was treading water. This is why the calculator asks for your margin.

### What is a good ROAS?

Most e-commerce teams target 3x–5x, but “good” is relative to your break-even point and growth goals. A subscription business with strong lifetime value can run profitably below 2x; a thin-margin retailer may need 5x+. Compare against your own break-even number first, category averages second.

### ROAS vs ROI

ROAS compares revenue to ad spend alone; ROI compares profit to total cost including product and overhead. ROAS is the faster in-platform signal for comparing campaigns — the profit figure above bridges the two by applying your gross margin.

## Your real ROAS depends on conversion data.

If Google Ads counts unqualified leads as conversions, every ROAS number lies. Adscriptly sends qualified outcomes — scored leads, real calls, closed deals — back to Google Ads so bidding optimizes toward profit.
