About WorkClockCalc
Simple tools for everyday time calculations.
WorkClockCalc helps you calculate a shift, total a time card, convert hours to decimals, and convert salary and hourly pay. The tools are free and require no account.
Calculations run in your browser. We do not collect calculator inputs or store them on a server. The site contains no advertising. When enabled, Google Analytics helps us understand page visits; calculator values are not sent as analytics events.
Our approach
We show formulas and examples so you can understand the result. These tools calculate elapsed time using your inputs; they are not an official timekeeping record or a payroll service. Verify important totals against your workplace’s policies.
