About Utilia Guides
Most personal-finance content online falls into one of two failure modes: vague advice that says nothing specific ("invest early and often") or dense technical writing aimed at professionals. Utilia guides take a different approach — they use real numbers, work through specific scenarios, and pair every concept with the calculator you would actually use to apply it to your own situation.
Finance guides cover topics that affect most households: mortgages, retirement savings, credit card debt, investment growth, and taxes. Each guide answers the question with a worked example — not just "how does compound interest work?" but "here's what $10,000 at 7% becomes over 10, 20, and 30 years, and here's how to calculate your own number." Home guides walk through a project step by step and link to the material estimator for it.
All guides are free and need no account. Each shows the date it was last updated; guides are revised when the rules they describe change, such as annual IRS limits or Social Security figures.
