CalcPilot is a small, independent project. Email is the fastest way to reach us — we read every message and usually reply within two business days.

Request a calculator

Tell us the calculation you need and the inputs you'd expect. Requested tools are prioritised by how often they're asked for.

Include the calculator name, the exact inputs you used and the number you expected. Formula issues are fixed first.

Questions about Premium, API Pro, invoices or cancellations — send the email address on the subscription so we can find it.
