About Us

Time Card Calculator is a free, independent tool built for one job: turning clock-in and clock-out times into accurate work hours, overtime, and pay — quickly, without ads getting in the way, and without asking you to create an account.

We built it because most free timesheet calculators online stop at basic hours worked and treat overtime as an afterthought. Overtime rules are often the part people actually need help with, so this calculator supports daily overtime, weekly overtime, and double-time together, with rounding rules and multiple saved timesheets, all updating live as you type.

What we believe

• Free should mean free. Every feature on this site is available with no account, no trial period, and no premium tier.
• Your data is yours. Timesheets are saved only in your browser. We don't collect or store them on any server.
• Calculators should get the details right. Overnight shifts, break deductions, rounding, and layered overtime rules are handled properly, not approximated.

Who's behind it

Time Card Calculator is built and maintained by an independent developer, kept small and focused on purpose rather than run as a larger company product.

This tool provides estimates for informational purposes and isn't a substitute for professional payroll, legal, or accounting advice. See our Terms & Conditions for details.
