How to Say “I’ll think about it” in Spanish Naturally

Introduction

Learning to express hesitation politely is essential for natural Spanish conversation. When you need time to consider something, knowing how to say I’ll think about it in Spanish helps you navigate decisions gracefully, whether you’re negotiating a purchase in Madrid, responding to a job offer in Mexico City, or simply declining plans with friends.

The Most Common Translation: Lo Pensaré

The most straightforward way to say I’ll think about it in Spanish is lo pensaré. This phrase uses the future tense of the verb pensar (to think) and literally translates to I will think about it.

Lo pensaré works perfectly in formal and informal situations alike. You might use it when:
• A salesperson asks if you want to buy something
• Someone invites you to an event you’re unsure about
• A colleague proposes a new project idea
• You’re considering a significant decision

Example conversation:
Vendedor: ¿Le interesa este modelo?
Tú: Lo pensaré y le aviso mañana.
(Salesperson: Are you interested in this model?
You: I’ll think about it and let you know tomorrow.)

Alternative Phrase: Voy a Pensarlo

Another natural option is voy a pensarlo, which uses the immediate future construction with ir + a + infinitive. This translates to I’m going to think about it and sounds slightly more conversational than lo pensaré.

Native speakers often prefer voy a pensarlo in everyday situations because it feels less formal. The choice between lo pensaré and voy a pensarlo is similar to choosing between I will and I’m going to in English—both are correct, but one may sound more natural depending on context.

Notice the word order difference: lo pensaré (pronoun before conjugated verb) versus voy a pensarlo (pronoun attached to infinitive). Both placements are grammatically correct in Spanish.

Adding Politeness: Déjame Pensarlo

When you want to sound more polite or buy yourself time gracefully, try déjame pensarlo, which means let me think about it. This phrase softens your response and shows you’re taking the matter seriously.

Déjame pensarlo is particularly useful when:
• Someone is waiting for your immediate response
• You want to acknowledge the importance of the decision
• You’re speaking with friends or family
• The situation calls for a gentle, non-committal answer

You can also use the more formal version, déjeme pensarlo, when addressing someone with usted. This shows respect while still requesting time to consider.

Example:
Amigo: ¿Quieres ir a la fiesta el sábado?
Tú: Déjame pensarlo. Te confirmo esta noche.
(Friend: Do you want to go to the party on Saturday?
You: Let me think about it. I’ll confirm tonight.)

Expressing Need for Time: Tengo Que Pensarlo

The phrase tengo que pensarlo means I have to think about it and emphasizes that consideration is necessary before making a decision. This construction uses tener que (to have to) plus the infinitive.

Tengo que pensarlo communicates that the decision requires careful thought, making it ideal for significant matters like job offers, major purchases, or relationship decisions. It carries slightly more weight than simply saying lo pensaré.

You might say:
Es una decisión importante. Tengo que pensarlo bien.
(It’s an important decision. I have to think about it carefully.)

Being More Specific: Lo Voy a Pensar Bien

Adding bien (well, carefully) to any of these phrases shows you’ll give the matter serious consideration. Lo voy a pensar bien or lo pensaré bien translates to I’ll think about it carefully or I’ll give it good thought.

This addition reassures the other person that you’re not dismissing their proposal casually. It’s especially appropriate for:
• Business negotiations
• Important personal decisions
• Situations where someone has invested effort in their proposal
• When you want to show respect for the offer

Regional Variations Across Spanish-Speaking Countries

While the phrases above work throughout the Spanish-speaking world, some regions have their own favorites. In Mexico, you might hear lo voy a pensar more frequently than other variations. Mexicans also commonly use déjame checar (let me check) in informal situations, though this technically means something slightly different.

In Spain, me lo pensaré (with the reflexive pronoun) is very common. This literally means I’ll think it over for myself and adds a contemplative nuance to the phrase.

Argentine speakers might say lo voy a pensar or add che at the end for emphasis: Lo voy a pensar, che. This regional particle makes the phrase sound more casual and friendly.

Caribbean Spanish speakers, particularly in Puerto Rico and Cuba, tend to drop the pronoun more often, simply saying voy a pensar in casual conversation.

When You Need More Time: Extended Phrases

Sometimes you want to be more explicit about needing time. Here are useful extensions:

Lo voy a pensar con calma means I’m going to think about it calmly, suggesting you won’t rush the decision.

Necesito tiempo para pensarlo directly states I need time to think about it, making your need for deliberation crystal clear.

Quiero consultarlo con la almohada is a charming idiomatic expression meaning I want to sleep on it. Literally, it translates to I want to consult it with the pillow, and native speakers love this phrase for major decisions.

Softening Your Response in Delicate Situations

When you suspect your answer might ultimately be no, but you want to avoid immediate rejection, try these tactful approaches:

Lo voy a considerar means I’ll consider it and sounds slightly more neutral than lo pensaré.

Voy a ver qué hago translates to I’ll see what I do and suggests uncertainty without commitment.

Lo tendré en cuenta means I’ll keep it in mind or I’ll take it into account, which is diplomatic but doesn’t promise active consideration.

These phrases help maintain relationships while honestly communicating that you’re not fully committed to the idea.

Cultural Context: The Art of Indirect Communication

Understanding cultural nuances enhances your Spanish communication. In many Spanish-speaking cultures, direct refusal can seem rude, so phrases like lo pensaré serve as polite buffers. Sometimes, I’ll think about it functions as a gentle way of saying no without causing offense.

This indirect communication style is particularly strong in countries like Mexico, Colombia, and Peru, where maintaining harmonious relationships often takes priority over direct honesty. In contrast, Spanish speakers from Argentina or Spain tend to be more direct, so lo voy a pensar there usually means genuine consideration.

Pay attention to body language and context. If someone seems enthusiastic when saying lo pensaré, they’re likely genuinely interested. If they avoid eye contact or seem hesitant, they may be politely declining.

Practical Tips for Using These Phrases Naturally

To sound more natural, combine your chosen phrase with other conversational elements. Instead of just saying lo pensaré, try:

Gracias por la oferta. Lo voy a pensar y te aviso pronto.
(Thanks for the offer. I’ll think about it and let you know soon.)

Me parece interesante. Déjame pensarlo esta noche.
(It seems interesting to me. Let me think about it tonight.)

Es una gran oportunidad. Tengo que pensarlo con mi familia.
(It’s a great opportunity. I have to think about it with my family.)

These fuller responses sound more engaged and respectful than a bare lo pensaré alone.

Common Mistakes to Avoid

English speakers often make these errors when translating I’ll think about it:

Avoid saying pienso sobre ello as a direct translation. While pensar sobre exists, pensar en or simply pensarlo sounds more natural for this context.

Don’t forget the pronoun entirely. Saying just pensaré sounds incomplete. You need lo pensaré or attach the pronoun to the infinitive as in voy a pensarlo.

Remember that pensar is a stem-changing verb (e→ie) in the present tense, but this doesn’t affect the future tense or infinitive forms used in these phrases.

Conclusion

Mastering how to say I’ll think about it in Spanish opens doors to more natural, nuanced conversations. Whether you choose lo pensaré, voy a pensarlo, or déjame pensarlo, you now have the tools to navigate decisions gracefully across Spanish-speaking contexts. Practice these phrases in real conversations, and you’ll soon sound like a native speaker.
