Tools & calculators

Marketing tools that start with the business, not the channel.

Free marketing tools and calculators that turn your economics, operating limits and growth targets into decisions you can actually use — before you spend more on anything.

Where they start

One level below the usual question.

Most marketing calculators begin with a channel and work outward. These begin with what the business needs and what it can support, then work backward to what marketing has to do.

Most calculators ask

  • How much should I spend on Google Ads?
  • How many leads do I need?
  • What ROAS should I aim for?

These start with

  • What outcome does the business need?
  • What can the economics support?
  • What can operations absorb?
  • What has to happen between demand and revenue?

The tools

Organized by the business they were built for.

An HVAC company and a product brand hit different limits, so their tools use different math. Each industry below shows the path demand has to survive, and where it usually stalls.

Why these tools exist

Why these tools exist

A calculator can’t make the decision for you. It can make the assumptions visible.
  • Organize the inputsPut the numbers that matter in one place, in the order the business actually runs.
  • Expose the mathShow how each result was calculated instead of handing back a single score.
  • Surface the assumptionsMake it obvious which inputs are driving the answer, so you know what to verify.
  • Ask better questionsPoint to what deserves investigation before more money goes out.

They don’t replace the people who run the business — operators, finance leaders or specialists. They give those conversations better starting numbers.

Questions

About the tools.

What kinds of marketing tools does Coast333 offer?

Interactive calculators and diagnostics built for specific industries. For HVAC, a growth forecast calculator and a marketing budget planner. For e-commerce, a diagnostic that helps product companies decide whether to spend more on marketing, hold, or fix another constraint first.

Are the tools free?

Yes. Every tool on this page is free to use, with no purchase required.

Who are the tools built for?

Owners and operators who understand their business better than their ad platforms — people who want to see whether a marketing decision makes sense for the company before committing to it.

Why do the HVAC and e-commerce tools use different calculations?

Because the businesses are limited by different things. An HVAC company’s growth depends on booking, closing and how many installs its crews can handle. A product brand’s depends on what each order leaves after product, fulfillment and acquisition costs, and on inventory and production capacity. The math has to follow the business.

Why not one marketing calculator for every industry?

A generic calculator can only ask generic questions, like cost per lead or return on ad spend. Those are useful, but they don’t tell you whether the business can convert, afford and absorb the result. Building each tool around one industry’s operating reality is what makes its answer usable.

Not sure which tool applies?

When the real problem isn’t obvious, a tool can only answer the question you bring to it. A Competitive Marketing Analysis looks at how three competitors you name are competing for customers online, then sorts what we find by what deserves attention first.
