Marketing Calculator FAQs
Everything you need to know about marketing metrics and calculations
What is ROAS and how do you calculate it?
ROAS (Return on Ad Spend) measures how much revenue you earn for every dollar spent on advertising. Calculate it by dividing total ad revenue by total ad spend. For example, if you spend $1,000 on ads and earn $5,000 in revenue, your ROAS is 5:1 or 500%. Use our ROAS Calculator to find yours instantly.
What is a good ROAS benchmark?
A good ROAS varies by industry. E-commerce typically targets 4:1 (400%), while SaaS or B2B may aim for 3:1 (300%) due to longer sales cycles. A ROAS below 2:1 (200%) means you're spending more than you earn. Use our Break Even ROAS Calculator to find your minimum profitable ROAS.
What is Customer Acquisition Cost (CAC)?
CAC is the total cost of acquiring a new customer, including marketing spend, sales team costs, and advertising. Calculate it by dividing total acquisition costs by the number of new customers. Our CAC Calculator helps you track and optimize this essential metric.
What is a good LTV:CAC ratio?
A healthy LTV:CAC ratio is 3:1 or higher — meaning a customer generates 3x more value than it costs to acquire them. Below 1:1 means you're losing money on each customer. Above 5:1 suggests you may be under-investing in growth. Use our LTV:CAC Calculator to benchmark your business.
What is the difference between CPM and CPC?
CPM (Cost Per Mille) is the cost per 1,000 ad impressions — used for brand awareness campaigns. CPC (Cost Per Click) is the cost each time someone clicks your ad — used for performance marketing. Our CPM and CPC calculators help you plan and optimize ad budgets for both models.
How do you calculate conversion rate?
Conversion rate is the percentage of visitors who complete a desired action (purchase, sign-up, etc.). Divide the number of conversions by total visitors, then multiply by 100. Our Conversion Rate Calculator makes it easy to track this key performance indicator.
