Guides

Guides are the "why" behind the calculators. Where a tool gives you a number in seconds, a guide walks you through the decision around it — in plain language, with the details that actually change the outcome. They're not a blog and not filler: each one is an evergreen, practical checklist tied to a specific tool, written to be useful the day you need it.

Right now the library starts where the questions are most expensive to get wrong — home financing. You'll find a documents checklist for a mortgage application (so nothing stalls your file), the questions worth asking a lender before you sign, and a clear explanation of how PMI quietly adds to your cost and how to get rid of it. Each guide links straight to the relevant calculator, so you can read the reasoning and run your own numbers without hunting around.

We're expanding the library alongside the tools — student and GPA guides, freelance pricing, and more — always following the same rule: answer a real question a real person is asking, cite the sources, and show the date it was last reviewed so you know it's current.

Everything here is information to help you make a confident decision, not personalised financial, legal or medical advice. Read the guide, run the matching calculator, and you'll walk into the conversation knowing your own numbers.
