Frequently Asked Questions
Sobre Esta Calculadora
Paid advertising generates a stream of metrics — impressions, clicks, conversions, spend, revenue — but the numbers that actually tell you whether a campaign is working are CPC, CPA, and ROAS. This calculator derives all three from your campaign data in a single place.
Cost Per Click tells you the price of each visitor from your ad. Cost Per Acquisition tells you the price of each customer or lead, which you can compare directly against your Customer Lifetime Value to determine profitability. Return on Ad Spend expresses total revenue divided by ad spend as a percentage, making it easy to compare efficiency across different campaigns and channels.
A ROAS of 100% means you broke even; 300%+ is typically the target for direct-response campaigns, though the right threshold depends on your margin. Enter your campaign data to see immediately whether your spend is generating a positive return.

Exemplo Resolvido
Evaluating a Google Ads campaign: $1,800 spent, 4,200 clicks, 63 conversions
Entradas:
- Total ad spend: $1,800
- Total clicks: 4,200
- Conversions: 63
- Revenue from conversions: $7,560
Passo a Passo:
- CPC = Total Spend ÷ Clicks = $1,800 ÷ 4,200 = $0.43 per click
- CTR (if 210,000 impressions): 4,200 ÷ 210,000 × 100 = 2.0%
- Conversion rate: 63 ÷ 4,200 × 100 = 1.5%
- CPA = Total Spend ÷ Conversions = $1,800 ÷ 63 = $28.57 per acquisition
- ROAS = Revenue ÷ Spend × 100 = $7,560 ÷ $1,800 × 100 = 420%
