· Base Rate: 2.0% (100 days)
· Preferential Interest Rate: Daily Accumulation Preferential Interest Rate of 0.1%p per annum (Maximum: 10.0%p per annum)
: Deposits can only be made through the deposit button in the Daily Savings (100-day) account. A 0.1%p accumulated interest rate is applied once a day for 100 days, accumulating to receive the preferential interest rate (up to 10%p per annum for daily deposits of 100 days).
* Deposits cannot be made via bank transfers, bank/interbank account transfers, or automatic transfers.
: The preferential interest rate applies only to accounts that have completed 100 deposits and are terminated upon maturity.
(If the account is terminated before the maturity date or after the maturity date without completing the 100th deposit, the preferential interest rate does not apply.)
[Example of Interest Calculation]
Deposit of KRW 30,000 daily for 100 days: KRW 49,808 before tax (maximum interest rate applies, details subject to change)

* Maturity Accelerated Interest Rate: Agreeable Interest Rate (including preferential interest rate) + 2.0% per annum
* Delayed Deposit Interest Rate: Agreeable Interest Rate (including preferential interest rate) + 2.0% per annum
* If the deposit amount is deposited later than the agreed date each day, ① the interest for the delay in deposit will be deducted from the maturity payment, or ② the maturity date may be delayed by the average number of days of delay per day.

① Late Deposit Interest = Daily Deposit Amount X (Total Number of Delayed Days - Total Number of Prepayment Days) / 365 X Deposit Late Interest Rate [= Agreeable Interest Rate (including Preferential Interest) + 2% per annum]
② Average Daily Delay = (Total Number of Delayed Days - Total Number of Prepayment Days) / Contracted Days (However, any amount less than 1 day is rounded up to 1 day)

Disadvantages of Deposit Cancellation
· If a savings account is canceled before the maturity date, the early termination interest rate applies (preferential interest rate does not apply).
· If a savings account is canceled after the maturity date without depositing the agreed-upon 100th installment, the early termination interest rate applies (preferential interest rate does not apply).

· Early Termination Interest Rate: Less than 1 month (0.1%), 1 month or more (Base Rate at the time of subscription (2.0%))

- Differential interest rates are applied for each deposit amount, depending on the deposit period, from the deposit date to the day before the early termination date.
- All interest rates granted upon early termination The preferential interest rate is excluded from interest rate calculation.
- Calculation method: Deposit amount per deposit X Premature termination interest rate per deposit period X Number of days elapsed until premature termination / 365
