Timesheet Calculator is published by Gabriel Dietsch. It lets you add up hours from a list of shifts. You can use it in a browser on this site and, when it is installed, inside ChatGPT. There is no fee and no account.

Estimates, not a paycheck

Results are arithmetic estimates. They are not payroll, tax, or legal advice. A default of 40 hours in the list matches a common US weekly threshold, and you can change it. Daily overtime, if you set it, is applied first and is not counted again toward that weekly threshold. Real workplaces follow their own contracts and local law, which this calculator does not know.

One calculation treats every shift you send as a single pay period. Split weeks yourself when each week has its own cutoff.

What you may do

Use the calculator for your own hours. Don't send unlawful content in a day label, and don't try to break the service. The email form stores an address for product updates and reminders. Don't submit someone else's address.

Availability

The site and the ChatGPT connection can change or stop. Hours you already calculated are not kept on our side, so keep your own copy if you need a record.

Liability

The calculator is provided as-is, without a warranty of fitness for payroll or any other purpose. To the extent the law allows, the operator is not liable for lost wages, missed overtime, or decisions you make from a result.
