About PTO Calculator
The PTO Calculator determines how many paid time off (annual leave) days an employee has earned based on their hire date and the Korean Labor Standards Act (근로기준법) accrual rules. For employees with less than one year of service, one day is earned for each full month worked (up to 11 days in the first year). Starting from one year of service, employees are entitled to 15 days. For every two additional full years of service, one extra day is added, with the maximum capped at 25 days per year. The tool handles all accrual tiers automatically from a single hire date input.
HR managers, payroll administrators, and employees themselves use this tool to verify their current PTO balance without consulting HR software. The calculator takes three inputs: hire date (date picker), the number of PTO days already used (defaulting to 0), and an optional daily pay rate for computing the monetary value of unused PTO at year-end. Remaining PTO = earned days − days used. The result is shown alongside years of service, total earned days, remaining days, and optional payout amount.
All calculations are performed entirely in the browser using JavaScript Date arithmetic. No hire date or salary data is ever transmitted to a server. The tool calculates the difference between the hire date and today's date in days, converts to years and months for accrual tier logic, and instantly updates results. It supports both Korean (won/원) and English (dollar/$) display formatting based on locale.

Frequently Asked Questions
How does the PTO accrual calculation work?
Under the Korean Labor Standards Act: employees with less than 1 year earn 1 day per full month worked. At exactly 1 year, 15 days are granted. For 2+ years: 15 + floor((years − 1) / 2) days, capped at 25. For example: 1 year = 15 days, 2 years = 15 days, 3 years = 16 days, 5 years = 17 days, continuing until reaching 25 days at approximately 21 years of service.
When does the 1-day-per-month accrual apply?
The 1-day-per-month accrual applies to employees who have not yet completed their first full year of service. For each full calendar month worked (calculated as 30-day intervals from the hire date), one day is earned. The maximum in this period is 11 days (months 1 through 11); upon completing 12 months the annual accrual of 15 days applies instead.
What is the maximum annual PTO under Korean law?
The Korean Labor Standards Act caps annual leave at 25 days. This maximum is reached when an employee has 21 or more full years of service (15 + floor(20/2) = 15 + 10 = 25). Employers may grant additional leave beyond 25 days voluntarily, but 25 is the legally mandated ceiling.
How is the unused PTO payout calculated?
Unused PTO payout = remaining days × daily pay rate. Enter your daily pay (일급) in the optional field — typically your monthly salary divided by a standard 22 working days, or your annual salary divided by 260. The result is the monetary compensation you are entitled to receive if unused leave is paid out at year-end or upon separation.
Does the calculator account for carry-over from previous years?
No. The calculator computes the current accrual year's earned days based on your service length. If your employer carries over unused days from previous years, you should add those to the "used days" field as a negative number, or manually adjust the remaining balance accordingly. Carry-over policies vary by employer beyond the statutory minimum.
What hire date format should I enter?
Use the date picker input (YYYY-MM-DD format in most browsers). For example, if you were hired on March 15, 2021, enter 2021-03-15. The calculator uses today's date as the reference endpoint for computing elapsed service time.
Can I use this for non-Korean employment?
The accrual tiers (15–25 days based on years of service) reflect the Korean Labor Standards Act. If your country or employer uses a different accrual schedule — for example, a flat 10 days per year or a monthly accrual rate — the earned days result may not apply. However, the remaining PTO and payout calculations are mathematically correct for any earned days input you manually verify.
Is my employment data safe when using this tool?
Yes. All calculations happen entirely within your web browser. Your hire date, salary, and leave usage data are never uploaded to any server, stored in a database, or transmitted to third parties. The data exists only in your browser's memory for the duration of the session.
