Contact us

We read everything. Write to us if a number looks wrong, if a calculator is confusing on your phone, or if there is a tool you keep wishing existed.

Email: hello@karodesk.com

When reporting a calculation issue, include the tool name and the exact values you entered, that makes it much faster to reproduce and fix.

Who you're reaching

KaroDesk is independently operated from India, a small, hands-on project rather than a large company, so expect a reply within two to three working days. Bug reports affecting a calculation are treated as urgent. See the about page for who builds and maintains KaroDesk.

Before you write

Many common questions already have a step-by-step answer in our business guides, for example how to calculate GST or the difference between markup and margin. For how results should be interpreted, see our disclaimer.
