Have a question about a tool, found a calculation that looks wrong, or want to suggest a preset? Use the form below. Messages go to Ready Utilities; the tools themselves store nothing you type.
When reporting a calculation problem, include the inputs you used and the result you expected. Please do not send invoices, client details, account numbers, or other sensitive information.

Replies are not guaranteed within a set time, but corrections to a tool are made as soon as they are confirmed. For a privacy request (to see, correct, or delete anything we hold about you), choose "General question" and put "privacy request" in the subject; we answer those within 30 days. What happens to a message you send is described in the privacy policy.
