Free Tools for Managing Hourly Teams

Calculators and templates for the math every service business does weekly: converting time card hours, splitting overtime, pricing labor, and keeping clean timesheets. Free, no signup, built by the team behind Chronotek Pro.

Time Card Calculator

Convert hours and minutes to decimal hours, total a weekly time card, and split regular from overtime.

  • Hours:minutes → decimal (4:30 = 4.50)
  • Overnight shifts and unpaid breaks
  • Configurable overtime threshold

Overtime Pay Calculator

Calculate time-and-a-half pay under the federal 40-hour rule — with a California daily-overtime mode.

  • Federal FLSA: 1.5x over 40 hours/week
  • California daily overtime and double time
  • Weekly gross pay breakdown

Labor Cost Calculator

Find an employee's true hourly cost: base wage plus payroll taxes, workers' comp, and overhead.

  • Loaded labor rate per hour
  • Weekly and annual cost projections
  • Built for job bidding

Free Timesheet Templates

Weekly and biweekly Excel timesheets with automatic totals, overtime splits, and gross pay — no signup.

  • Excel format, imports into Google Sheets
  • Automatic per-week overtime at 1.5x

Frequently Asked Questions

Are these tools really free?

Yes. Every calculator and template on this page is free to use and download, with no signup, email, or credit card. They are built and maintained by Chronotek, makers of the Chronotek Pro GPS time clock.

Do the calculators store my data?

No. All calculations run in your browser — nothing you type is sent to a server or stored. Refreshing the page clears your entries.

When should I switch from templates to time tracking software?

Templates work while your team is small and on-site. Once crews spread across job sites, spreadsheets can’t verify anyone was actually there — that’s when a GPS time clock with automatic timecards, schedules, and no-show alerts pays for itself. Chronotek Pro has a 30-day free trial.

Tired of doing this math by hand?

Chronotek Pro captures exact clock-ins with GPS verification, totals every timecard automatically, and flags overtime before it happens. Try it free for 30 days.
