Welcome to the EconKit blog

EconKit has shipped 39 business calculators, a 57-term glossary, and a growing library of comparison pages. All of them answer a specific question in a specific format: fill in some numbers, get an answer with benchmarks and insights.

That format is powerful, but it’s also narrow. A calculator can tell you that your freelance hourly rate should be $127 if you want to take home $85,000, have 25% overhead, 10% profit margin, and pay 30% in taxes. It can’t tell you why freelancers consistently underprice themselves, how to actually move to a higher rate without losing clients, or whether the entire “hourly rate” framing is even the right way to think about your business.

That’s what this blog is for.

What you’ll find here

Each post will focus on a specific business metric or decision, written in plain English, without the “here are the 37 things to consider” list format that plagues business writing. The goal is to leave you with:

• A clear mental model of the concept
• The handful of numbers that actually matter
• A link to the calculator where you can plug in your own data
• Honest caveats about where the framework breaks down

Expect posts on:

• Pricing: how to set rates, when to raise them, why anchoring matters more than cost-plus math
• Unit economics: CAC, LTV, payback periods, and the gotchas that make these metrics lie
• Cash flow and runway: the difference between burn rate theater and actual financial health
• Freelance economics: the hidden math of independent work that W-2 employees never have to think about
• SaaS metrics: MRR, churn, expansion, NRR, and which ones your board actually cares about
• E-commerce profitability: the difference between revenue and profit on Shopify, Amazon, and marketplaces

How this connects to the calculators

Every post will be paired with the calculators it references. The sidebar on the right shows the related calculators for this post — they’re the tools you’d reach for after reading. That’s the pattern we’ll follow: explain the concept in the post, then hand you the tool to apply it to your own numbers.

Where the concept is subtle enough that a calculator alone can mislead you, the post will spell out the edge cases. Where the calculator already covers the subtleties with its benchmarks and insights, the post will keep things short and point you there.

What we won’t do

• No SEO filler. Every post will be written because it’s useful, not because a keyword tool says a search term has high volume.
• No fake authority. The author line says “EconKit Team” because we’ll update posts as we learn more. If the framework in a post turns out to be wrong or incomplete, the post gets updated with a changelog at the bottom.
• No engagement bait. No “the #1 mistake founders make” headlines. No numbered lists for the sake of numbered lists. No AI-generated fluff.

Why start a blog now

EconKit’s calculators already cover the mechanics. What’s missing is the context — the reasoning behind which numbers matter and why. A calculator gives you an answer; a good article gives you the understanding to know when the calculator’s answer is right for your situation and when you should push back on it.

That understanding is also the durable moat against AI substitution. Anyone can ask ChatGPT for a rough calculation. Fewer people know which calculation to ask for in the first place, or how to read the result. That’s where long-form content earns its place.

More soon.
