How does the Christmas bonus calculator work?

The aguinaldo, also called the 13th salary or annual complementary salary, is a benefit equal to one twelfth of everything you earned during the year. Our calculator uses the proportional method: enter your gross monthly salary and the number of months you worked, and you get the exact amount you should receive.

Christmas bonus formula

Bonus = Monthly salary × Months worked / 12

Where:

  • Monthly salary = your gross pay each month
  • Months worked = the months actually worked in the year (1 to 12)

Worked example

Suppose your monthly salary is 6,000,000 and you worked 8 months in the year. The calculation is:

  • 6,000,000 × 8 = 48,000,000
  • 48,000,000 / 12 = 4,000,000 bonus

If instead you worked the full year (12 months), you receive one whole monthly salary: 6,000,000.

Tips to make the most of your bonus

  • Do not spend it all: put at least part toward paying off expensive debt (credit cards) or an emergency fund.
  • Make it grow: a fixed-term deposit or an investment fund can turn your bonus into more money before next year.
  • Plan for early-year expenses: tuition, taxes and insurance often cluster in January; setting aside part of the bonus avoids financial stress.
  • Check your employer's math: use this tool to confirm the amount paid matches what you are owed.

Frequently asked questions about the Christmas bonus

The aguinaldo (13th salary) equals one twelfth of all the pay earned during the year. If you worked the full year you receive one monthly salary; if you worked less, it is prorated: monthly salary times months worked, divided by 12.

You are entitled to a proportional bonus. For example, if you worked 6 months with a salary of 6,000,000, you get 6,000,000 × 6 / 12 = 3,000,000, that is, half a bonus.

In most countries in the region the bonus is calculated on gross pay. Deductions (contributions and, in some countries, income tax) may apply afterward depending on local law.

Usually yes. The bonus is based on total earnings, which often include regular pay items such as overtime, commissions and habitual bonuses. This calculator uses your monthly salary as the base; add those extras to the average for a closer estimate.

It varies by country. It is usually paid at year-end (December) and, in several countries, in two installments: one mid-year and one in December. Check your country regulations for exact dates.
