Method
Retirement pay estimate = applied daily wage × 30 × service days ÷ 365. Daily average wage = wages paid in the three calendar months before retirement, plus 3/12 of eligible annual bonus and eligible annual-leave pay, divided by the exact calendar days in that period. If daily ordinary wage is higher, this estimate applies that amount. The one-year eligibility warning uses the first calendar anniversary, including the civil-calendar boundary for a 29 February start; the payment amount still uses actual service days ÷ 365. Excluded periods, whether a payment is legally wages, interim settlements, retirement-pension plan terms and tax are outside this calculator.
Primary method: Ministry of Employment and Labor retirement-pay calculator and example. Calendar-year eligibility: Ministry 1350 retirement-pay guidance and Civil Act Article 160. The official calculator instructs users to enter the retirement date as the day after the last day worked, allocates annual bonus and eligible leave pay at 3/12, and applies ordinary wage when higher.
