Your E-commerce Questions, Answered
A few common questions we get from founders.
What is a good ROAS for an e-commerce business?
While it varies by industry and profit margins, a common benchmark for a good ROAS is 4:1 — meaning you generate $4 for every $1 spent on ads. A ratio of 2:1 is often considered the break-even point after accounting for product costs. Our tools help you find the exact number you need to be profitable.
Are these tools really free to use?
Yes, all the calculators on our site are 100% free to use, with no sign-up required. Our mission is to provide accessible, high-quality tools for the community. In the future, we may introduce advanced AI-powered tools that operate on a freemium model.
What makes mktgrowkit different from other tool suites?
Simplicity and focus. We are not a bloated, all-in-one platform. Each tool is designed to do one job exceptionally well, with zero fluff or confusing dashboards. We're built by a solo builder for founders and marketers who value speed and clarity.
