Overtime Pay Calculator by Country

Overtime premiums under each country's own labour code — Mexico's double-then-triple rule, Colombia's night premium, and the fact that Spain has no legal multiplier at all.

What the 1.5× Rule Gets Wrong

Mexico does not use a multiplier at all: the first nine weekly overtime hours are paid double, and everything beyond that is paid triple.
Colombia pays a 35% night premium on ordinary hours worked after 9pm, whether or not they are overtime. It is a separate concept.
Spain sets no legal overtime rate. The collective agreement decides, and the default is ordinary pay or compensating rest.
The hourly rate is not the salary divided by 160. Each country has its own legal monthly divisor, from 173 hours in Spain to 220 in Brazil.

Why One Formula Cannot Cover Eight Countries

Almost every overtime calculator online applies the rule from the United States Fair Labor Standards Act: time and a half beyond forty hours. That rule does not exist anywhere in Latin America or in Spain. Mexico pays double time for the first nine overtime hours in a week and triple time after that, so a worker doing twelve hours is paid at two different rates in the same week. Colombia distinguishes overtime from a night premium that applies to ordinary hours after 9pm. Brazil sets a constitutional floor of 50% that collective agreements routinely raise. Spain, uniquely on this list, sets no statutory rate at all. Applying a single multiplier to all of them produces a number that is wrong in every case except by accident.

The Working Week Is Not 40 Hours Either

Before any premium applies you have to know where the ordinary week ends, and that varies as much as the premium itself. Spain works 40 hours, Brazil and Chile 44, Colombia is stepping down to 42 under Law 2101 of 2021, and Mexico, Peru and Argentina remain at 48. The same variation applies to the monthly divisor used to derive an hourly rate from a monthly salary — 173 hours in Spain, 190 in the Dominican Republic, 208 in Mexico, 220 in Brazil. That divisor is why the same salary produces a different hourly rate in each country before a single premium is added, and why a generic calculator is wrong twice over: once on the base rate and once on the premium.

Legal Limits on Overtime

Mexico: three hours a day, three times a week. Beyond that, the excess is paid triple regardless of the weekly count.
Colombia: two hours a day and twelve a week, and it requires authorisation from the labour ministry.
Brazil: two hours a day, unless a compensation agreement (banco de horas) is in place.
Peru: overtime is voluntary on both sides. Requiring it without consent is grounds for a complaint.
Spain: 80 hours a year, not counting hours compensated with rest within four months.
Dominican Republic: 68 hours a week in total, above which every hour is paid at 100%.

Common Payroll Errors

Paying overtime on the base salary alone when the country's rules include regular bonuses in the hourly rate.
Treating the night premium as overtime in Colombia. They stack: a night overtime hour carries both.
Compensating overtime with time off where the law does not allow it, or without the written agreement it requires.
Counting the working week from Monday when the contract or agreement defines a different cycle.
Rounding hours down. Fractions of an hour are payable in every country on this list.
Assuming managers are exempt. The exemption is narrower than employers usually claim, and misclassification is common.

Worked Examples

The two-tier rule and a flat premium

Mexico, $10,000 a month, 9 hours

Ordinary hour = 10,000 ÷ 208 = 48.08
First 9 hours at double: 48.08 × 2 = 96.15
96.15 × 9

$865.38 for the week

Dominican Republic, RD$30,000, 12 hours

Ordinary hour = 30,000 ÷ 190 = 157.89
Premium 35%: 157.89 × 1.35 = 213.16
213.16 × 12

RD$2,557.89 for the week

Frequently Asked Questions

How is overtime calculated in Mexico?

The first nine overtime hours in a week are paid at double the ordinary hourly rate, and every hour beyond the ninth is paid at triple, under Articles 67 and 68 of the Federal Labour Law. There is no time-and-a-half in Mexican law.

What is the night premium in Colombia?

35% on top of the ordinary hourly rate for work between 9pm and 6am, under Article 168 of the Labour Code. It applies whether or not the hour is overtime, and a night overtime hour carries both the premium and the 75% overtime rate.

Does Spain have a legal overtime rate?

No. Article 35 of the Workers' Statute leaves the rate to the collective agreement or the individual contract, and sets only a floor: overtime may not be paid below the value of an ordinary hour. Many agreements compensate with rest instead of pay.

How do I work out my hourly rate from a monthly salary?

Divide the monthly salary by the legal monthly hours of your country, which is not the same everywhere: 173 in Spain, 190 in the Dominican Republic, 199 in Colombia, 208 in Mexico, Peru and Argentina, 220 in Brazil.

Is overtime taxed differently?

In most of these countries overtime is ordinary taxable income. Mexico is the exception worth knowing: overtime within the legal limit is exempt from income tax up to a ceiling tied to the minimum wage, for workers earning the minimum.

Can my employer make me work overtime?

Generally no. In Peru and Spain it is voluntary on both sides; in Mexico and Colombia it is capped by law and, in Colombia, requires ministry authorisation. Overtime imposed beyond the legal cap is claimable and still payable.
