Free marketing tools that do the maths.
The free tools from Dynamic Growth are small utilities for the questions that come up in every marketing review: is our setup healthy, are our ads paying for themselves, are our links tagged correctly, and what can we afford to pay for a customer. Each one runs in your browser and needs no signup. They're upfront about their limits. A calculator can only work with the numbers you give it, so every tool explains its formula, how to read the result, and the mistakes that usually skew it. When a result points to real work, the page links to the guide and service that cover the next step.
Who these tools are for
Small business owners
You run the business and oversee the marketing too. These tools give you a quick, plain read on whether spend and setup are sound, before you pay anyone to dig deeper.
In-house marketers
You manage channels without a large team. Use the calculators to sanity-check budgets, standardize link tagging across campaigns, and build a simple case for next month's plan.
Founders watching cash
You need to know how much you can spend to win a customer without losing money. The ROAS and CPA tools turn margin and order value into limits you can act on.
Freelancers and consultants
You support several clients and need consistent checks. Use the tools to start audits, explain break-even math simply, and keep campaign naming tidy across accounts.
Free tools questions
Are the free tools really free?
Yes. You can use each calculator and builder without paying or creating an account. Nothing in them is locked behind a purchase. If a result suggests deeper work, you can choose a Dynamic Growth service.
Do the tools store the numbers I enter?
The calculators do their math from the values you type on the page. Avoid entering anything sensitive, such as customer names or private account details. Totals like spend, clicks, conversions, and margin are all you need for useful results.
How accurate are the results?
The math is exact for the inputs you provide, but the inputs are the weak point. Spend, conversions, and margin all depend on how you measure them. Treat outputs as a starting point, and compare them against what your ad platforms and analytics report.
Which tool should I start with?
Start with the Marketing Health Score if you're unsure where problems sit. Use the ROAS or CPA calculator when you're judging ad profitability, and the UTM Builder before launching any campaign so your traffic reports are clean from day one.
Can these tools replace an audit or an agency?
No. They give quick answers from limited inputs, while an audit looks at your actual site, tags, and pages. Use the tools to find out where to look, then use a guide or a service to fix what they surface.
Turn the numbers into a plan
Run an audit on your own website and see which fixes matter most.
