계산하다

The word 계산하다 is a fundamental verb in Korean that acts as a bridge between logic and daily commerce. At its core, it refers to the act of computing or calculating values.

Think of it as the mental or mechanical process of arriving at a specific number. Whether you are doing homework or checking your bank balance, you are 계산하다. In a social setting, it shifts to the act of paying. When you finish a meal, you 'calculate' the cost to settle the bill. It is an essential word for anyone traveling or living in Korea.

The word is rooted in Sino-Korean characters (Hanja). 계 (計) means to count or plan, and 산 (算) also refers to counting or calculating. Combined, they create a powerful term for assessment.

Historically, this reflects the ancient need for trade and inventory management. In traditional markets, merchants used sanjibop (counting rods) to perform these operations. Over centuries, the term evolved from purely mathematical usage to the common social act of settling debts, which is why it remains the standard way to say 'pay the bill' today.

You will use this word in two primary contexts. In mathematics, it is used with objects like 'math problems' (수학 문제) or 'numbers' (숫자). In commerce, it is used with 'bills' (계산서) or 'prices' (가격).

When you are at a restaurant, you might say '계산할게요' (I will pay). It is neutral and polite. For very formal business settings, you might hear '결제하다' (to make a payment/authorize), but 계산하다 is perfectly acceptable in almost every daily situation.

1. 계산이 빠르다: To be quick at calculating (often used for someone who is clever with money or benefits). 2. 계산에 밝다: To be good with numbers/business-savvy. 3. 계산기를 두드리다: To tap a calculator (to think carefully about pros and cons). 4. 계산이 서다: To have a clear plan or expectation of an outcome. 5. 계산을 마치다: To finish the calculation/payment process.

As a -하다 verb, it is highly regular. You can conjugate it as 계산해요 (polite) or 계산했다 (past tense). It functions as a transitive verb, meaning it usually takes an object marked by -을/를.

Pronunciation is straightforward: gye-san-ha-da. Ensure the 's' is crisp. It rhymes loosely with words ending in -ada, though the focus is on the clear articulation of the three distinct syllables in 계산.
