When hiring internationally, you may encounter the concept of additional salaries, often called the 13th and 14th month salaries. These extra payments are legally mandatory in some countries or customary in others. Offering a 13th and 14th month salary is either required for compliance or highly advisable to ensure your compensation package is competitive.
But what is it?
The 13th month salary is an additional month of pay that is usually paid at the end of the year or in instalments throughout the year. This payment is typically considered a statutory salary component, not a discretionary bonus.
Howeverm, a 14th month salary is a second additional salary payment, found in certain countries, again equivalent to a month of salary and usually paid in 1 fixed instalment mid-year or at the end of the year. Unlike the 13th month salary, the 14th month salary is less common globally and more concentrated in specific regions and is more likely to be discretionally rather than statutory.
If you are used to operating in jurisdictions without this concept, it can seem odd but it’s an important element in the countries that do utilise it.
What is the Difference Between 13th Month Salary and 14th Month Salary?
The 13th month salary is one monthly wage which is often but not always paid out to employees at the end of the year like a Christmas bonus. Depending on the country, this payment can be classed as mandatory or customary. However, 14th month salary is usually paid out to employees, either mid-year (June/July) or at the end of the year (December). The 14th month salary is less common than the 13th month salary.

Countries with 13th and 14th Month Salary
The 13th and 14th monthly salary is mandatory in certain countries, whereas others it is customary. However, for those countries where it is not legally enforced, businesses can choose to offer a 13th month salary. When it isn’t offered it can be difficult attracting and retaining top talent.
In some countries, the concept of additional salary goes by a different name but is broadly the same concept. Employees in Mexico are entitled to a Christmas bonus called the ‘Aguinaldo’. Mexican law mandates that employees are entitled to a minimum of 15 days of additional pay by 20th December each year.
In Brazil, the 13th month salary is legally required under Federal Law NO. 4,090/1962. In Portugal, the Portuguese Labour Code (7/2009) outlines that the 13th month salary (Christmas allowance) and the 14th month salary (holiday allowance) is also legally required.

How to Calculate 13th Month Salary
To calculate a 13th monthly salary, take the sum of your employee’s basic earnings within the calendar year and divide it by 12. (As this is the standard calculation, this may differ depending on the country.)
13th Month Salary = Total Basic Salary Earned During the Year ÷ 12
But what counts as “basic salary”? There are certain exclusions which need to be taken into consideration including commissions, allowances, overtime and unpaid time off. The 13th month calculation will vary depending on these factors.
For example:
If an employee earns £2,500 (gross basis) and has worked a full year:
- £2,500 x 12 = £30,000
- £30,000 ÷ 12 = £2,500 = 13th month payment
For an employee who started working mid-way through the year (also known as a mid-year hire) their 13th month payment equation will look like this:
13th Month Salary = Monthly Base Salary x Months Worked in Year ÷ 12
For example:
If an employee earns £2,500 (gross basis) and is a mid-year hire (assuming they started work on the 1st of July):
- £2,500 x 6 = £15,000
- £15,000 ÷ 12 = £1,250 = 13th month payment
