About SolvCalc

SolvCalc is a free set of calculators and short guides for everyday numbers: what a loan costs, what saving adds up to, how to split a bill, how many days until a date. We make them because we got tired of tools that bury a simple answer under pop-ups, sign-ups and jargon.

What you can expect

• Clear answers first. The headline number is at the top, with the working underneath.
• No account. Open a page and use it.
• Privacy-minded. Calculations run in your browser, and what you enter does not leave your device.
• Honest limits. We say what a calculator leaves out, such as fees, taxes or medical context.

How we check our work

Before a calculator goes live, we test it against worked examples whose answers we have calculated independently. When a reader points out a mistake or a clearer wording, we fix it and update the page.

How the site pays for itself

SolvCalc shows advertising on some pages. This covers hosting and the time it takes to build and maintain the tools. We keep ads clear of the calculators themselves, and we do not sell personal information.

A note on advice

Our tools and guides give general information. They are not financial, tax, legal or medical advice. For big decisions, please speak to a qualified professional.
