When learning Spanish, mastering numbers is a crucial skill. From counting to a hundred to expressing quantities in the billions and trillions, understanding numbers in Spanish 100 and beyond opens up a world of possibilities for communication. 

In this blog post, we’ll explore how to write big numbers in Spanish, providing you with the tools to handle large numerical values with confidence. When you finish reading this blog post, you’ll be ready to write big cheques in Spanish! Ja!

Additionally, I’ll share with you my go-to resource that teaches all numbers in Spanish from 0 to a trillion. It’s a PDF you can get your hands on whether you’re a student looking to enhance your skills or a teacher seeking for a new teaching tool. Read until the end to see this incredibly useful material!

1. Numbers 100 to 999:

Let’s start with the hundreds. In Spanish, the number 100 is “cien”. However, once we start adding units like 101, 102, 140, “cien” becomes “ciento” as in ciento uno, ciento dos, ciento cuarenta. Numbers from 200 to 900 are formed differently. First we mention the number from 1 to 9, then we add the word ciento, and after that whatever numbers comes next. See the examples below:

200: doscientos

303: trescientos tres

467: cuatrocientos sesenta y siete

Unfortunately, there are some exceptions to the rule, which apply to the numbers 500, 700 and 900. Quinientos is the word for 500; setecientos for 700; and novecientos for 900. 

2. Thousands and Beyond:

Moving on to even bigger numbers, writing thousands and beyond in Spanish is simple and logical. For instance, “mil” means “one thousand,” “dos mil” means “two thousand,” and so on. To express numbers like one million, one billion, or one trillion, the word “millón,” “mil millones,” and “un billón,” respectively, are used.

Note that there’s a false friend with the word “billion” in English, which in Spanish is “mil millones.” Therefore “un billón” in Spanish is actually a trillion in English. Take this into account especially when you’re giving stats or information in Spanish. 

3. Comas and Points:

In Spanish, large numbers are written differently from English. While English uses commas to separate thousands, Spanish uses points. For example, “10,000” in English is written as “10.000” in Spanish. On the other hand, decimals are indicated with commas in Spanish, as in “3,14” for the English “3.14.”

A clear example of how we use commas for decimals is when you look at prices at a market or shop. You’ll notice prices with decimals are always written with commas as in the image below:

4. Watch Out for Gender Agreement:

When writing big numbers in Spanish, gender agreement remains important. The numbers “uno” plus all the “cientos” (200, 300, etc) must match the gender of the noun they refer to. For example, “doscientas casas” (two hundred houses) uses the feminine “doscientas” to agree with “casas” (houses). See more examples below:

5. Practice Makes Perfect:

To feel confident in writing big numbers in Spanish, practice is key. Work with various numerical values, write them out, and read them aloud. Engage in exercises that involve converting numbers from digits to words and vice versa. The more you practice, the more natural and accurate your writing will become.
