Thirteenth Salary Calculator Formulas

Full Year Method

13th Salary = Monthly Salary × 1

Condition: Worked full calendar year

Example: $3,000 monthly = $3,000 13th salary

Prorated by Months

13th Salary = (Monthly Salary ÷ 12) × Months Worked

Months Worked = Complete months of employment

Example: ($3,000 ÷ 12) × 9 months = $2,250

Prorated by Days

13th Salary = (Monthly Salary ÷ 365) × Days Worked

Daily Rate = Monthly Salary ÷ 30.44 (avg days/month)

Example: ($3,000 ÷ 365) × 270 days = $2,219
