About SmartCost Lab

SmartCost Lab is an independent website of practical calculators for everyday costs — energy, driving, heating and household money — built for people in the United States, United Kingdom, Canada and Australia.

What we believe

• Show the working. Every calculator explains its formula in plain English, so you can check it or redo it on paper.
• Never invent numbers. Default prices come only from official sources with the period they cover printed beside them. If we don't have a trustworthy figure, we ask for yours.
• Respect your data. Calculations run in your browser. We don't ask you to sign up, and share links leave out personal figures unless you choose otherwise.
• Visitors before revenue. The site may carry advertising in future to pay for itself. Ads will never sit inside a calculator or change its results, and no sponsor can buy a result.

Who runs it

SmartCost Lab is owned by Sait Naç and built and maintained with the help of automated tools that research official data, test every formula, and flag outdated rates for review. All content and changes are reviewed against our methodology and editorial policy.
