About Utilia

What Utilia Covers

Utilia is a set of free calculators for US personal-finance decisions, plus a small set of material estimators for home projects. The finance calculators cover mortgages and home buying, loans and debt, retirement and Social Security, investing, saving and budgeting, and federal tax and pay. The home calculators estimate materials for projects like concrete slabs, fencing, decks, flooring and paint.

The finance guides explain the decisions behind the numbers, such as when refinancing pays off or how the order of investment returns affects a retirement portfolio. Each one links to the calculator that lets you run your own figures.

Why the Focus Is Narrow

Utilia used to include health and general math calculators as well. In September 2026 those were retired. They were the same tools available on hundreds of other sites, and the health tools in particular needed clinical expertise the site doesn't have. The remaining calculators are the ones where Utilia can add something: US-specific rules (IRS contribution limits, RMD tables, Social Security claiming ages, CFPB closing-cost categories) implemented carefully and cited so you can check them.

Near-duplicate calculators were merged at the same time, so each question now has one tool that answers it well. For example, hourly-to-salary and salary-to-hourly became a single two-way calculator.

Who Builds It

Utilia is built and maintained by Akshaya Panda, an engineer, working alone. There is no editorial team. The author is not a financial adviser, accountant or tax professional, and nothing on the site is personal financial, tax or legal advice.

That is why every calculator names the formula it uses and, where an official rule applies, links to the source: IRS publications, Social Security Administration rules, CFPB guidance, BLS inflation data. The authority belongs to the source; Utilia's job is to implement it correctly and show where it came from.

How Calculators Are Checked

Each calculator is tested against worked examples computed independently before it goes live, and rechecked when the underlying rule changes, such as the annual IRS inflation adjustments to tax brackets and contribution limits. Every page shows the date it last changed. The calculator methodology and how calculations are derived pages go into detail, and the editorial policy explains what gets published and how corrections are handled.

Privacy and Funding

Calculations run in your browser. The numbers you enter aren't sent to a server or stored, and no tool requires an account. The site is free and supported by display advertising (Google AdSense), placed below the calculator rather than above it. See the privacy policy for how analytics and advertising cookies are used.
