What is JustResearching?
JustResearching is a set of free calculators and small tools for the questions that come up around work and money. What did that meeting cost? What interest can you charge on a late invoice? How many working days are left before the deadline? Each tool does one job, shows how it reached the answer, and does not ask you to sign up.
Most of them run in your browser, so what you type stays on your device. Where a result depends on a rule or a rate, such as UK statutory interest on late payments, the page says where it comes from so you can check it yourself. The results are estimates and general information, not advice.
There are also a few games for when you need a break. They are the reason for the name. The site is made and looked after by one person, and you can read more on the About page.
