How to get a reliable answer
Every calculator on this page runs entirely in your browser, so nothing you type is sent to a server or stored. Enter your own figures rather than the defaults, check the units next to each field, and read the breakdown under the main result — it shows how the number was reached so you can sanity-check it against your own paperwork.
