How it's used

Primarily used in financial contexts to denote the number of installments for a loan or purchase. When referring to prison time, it carries a very specific, somewhat gritty connotation regarding the duration of a sentence. Note that in casual speech, people often drop the 數 and just use 期 when counting payments.

Examples

This contract is split into twelve installments for payment.
How many installments do you still have left to pay?

Common phrases

to pay in installments
how many installments to pay

Common mistake

Do not confuse this with 期限, which refers to a deadline or a fixed time limit. Using 期數 for a deadline will sound confusing to native speakers.
