Reporting a wrong number

This is the message we most want to receive. If a fee rate or a formula looks wrong, send the page address and what you think the correct figure is — a link to the marketplace's own rate card is ideal. Corrections to published rates are usually live within a day or two.

Requesting a calculator

Tell us the calculation and, if you can, the exact wording you would have searched for. We keep a list and build the ones people actually ask for.

Advertising and partnerships

We run display advertising and a small number of affiliate links to seller software. We do not sell guest posts, link placements or sponsored calculators, and no commercial arrangement changes what a calculator outputs or where a tool appears in a list.

Response time

This is a small operation. Expect a reply within a few working days. Corrections get looked at first.
