시프티 계산기 (Shiftee Calculator) is a Chrome extension that analyzes registered work schedules from the Shiftee attendance management system to calculate overtime pay. This handy tool utilizes standard hourly wage calculation methods and overtime pay calculation methods.

To calculate the hourly wage, it divides the annual salary by 12 months and 209 hours. Overtime pay is calculated at 1.5 times the base wage. If the overtime work falls within the night shift, from 10 PM to 6 AM, it is calculated at 2 times the base wage. However, the extension caps the maximum overtime hours at 52 hours.

With 시프티 계산기, users can easily determine their overtime pay based on their registered work schedules in the Shiftee attendance management system. This Chrome extension provides a convenient and efficient solution for calculating overtime wages.
