DimeTime — Part-Time Payroll

A payroll calculator that fits in a small business owner's hand.

Each part-time worker has a different hourly wage and a different schedule. Months land on 21, 22, or 23 working days. On top of that you need to factor in the weekly holiday allowance (주휴수당) and 3.3% withholding tax. Calculating just one person's pay can eat up an hour.

DimeTime does that math for you. Register a worker once, check them in and out from a calendar, and the monthly net payout is ready when payday hits.

■ How it calculates

· Effective hourly = (weekly base + holiday allowance) ÷ weekly hours
· Holiday allowance = average daily hours (max 8h) × hourly wage, when weekly hours ≥ 15
· Net = gross × 0.967 (3% income tax + 0.3% local tax)
