KakaoBank's "one-month savings" product surpassed 14 million cumulative accounts 2 years and 5 months after its launch.

Launched in October 2023, the one-month savings product is a short-term installment savings plan designed to help users build saving habits by putting aside small daily amounts from 100 won to 30,000 won.

It reached 5 million accounts about 7 months after launch and 10 million accounts after 1 year and 5 months. It topped 14 million early this month.

The customer base has also expanded. At the start, users in their 30s and younger made up a large share, but customers in their 40s now account for 31 percent and those 50 and older 32 percent, or 63 percent combined. Women accounted for 72 percent of users.

KakaoBank also runs the product as a "partner savings" offering linked to various companies including Samsung Electronics, LG Electronics, Hana Securities, Baskin-Robbins and Gmarket, providing additional benefits.

A KakaoBank official said the perception of it as an easy, low-burden product, combined with an added fun element, helped it reach 14 million accounts quickly. The official said the bank will continue to offer customers greater benefits and convenience through differentiated products and services.
