About

StreamerOS Money Calculators is a small set of free calculators for everyday money questions: pay raises, salary and hourly conversion, overtime and time and a half, and currency conversion between any two currencies, with short guides that explain the rules behind them.

It is built and maintained by Yaseen Khatib, a full-stack AI engineer, as part of the StreamerOS project. The calculators exist because many are cluttered and never show how the answer is reached, so every page here states its formula and a worked example.

How the calculators work

Every calculator runs in your browser using standard JavaScript. The figures you enter are processed on your device and are not sent to a server or stored. The currency tools download a public list of exchange rates; your amounts are never part of that request. The site is a static website hosted on GitHub Pages.

What the results are, and are not

Pay results are estimates of gross pay before tax and other deductions. Currency results use mid-market reference rates from a free public feed, which can be up to a day old and are not the rate a bank or transfer service will give you. None of it is financial, tax or legal advice. Overtime rules in particular vary by state and by job, so check your payslip or your state labor department for the exact rule that applies to you.

How the site is funded

The calculators are free. The site may show Google AdSense ads to cover hosting and development time. Ads never change the result of a calculator.
