Calculators that do the arithmetic the software does
Each one is a port of the product's own code rather than a simplified version of it, so it stops where the software stops and says why. Free, no sign-up, and nothing you type leaves your browser.
Calculators
The rules are the product's, not a summary of them. Where the software refuses to give an answer, so does the calculator, and it says what it would need.

Two parts of the software running on this page, on demonstration data.
Why they are here
An answer you can check
Murgese Ltd is a small company and nobody has heard of it. We are not going to put a wall of logos on this website, because we would have to invent them, and we are not going to tell you how many hours a week you will save, because we do not know. What we can do is show you the arithmetic and let you check it against a case you already know the answer to.
Each of these is a port of the module the software runs, named on its own page, and each one stops where the software stops. None of them is advice. They are the sums, and your own circumstances and your own contract come first.
If one of them is wrong, tell us and we will fix it in the product as well as on the page.

These pieces do a small part of what the software does. Request it and run a period you already know the answer to.
