Best Savings Accounts in Korea 2026: Highest Interest Rates Compared
In 2026, the highest savings interest rates in Korea come from savings banks (jochuk eunhaeng) and internet banks. Traditional commercial banks offer 2-3% annual rates, while internet banks like Kakao Bank and Toss Bank offer 3-4%, and savings bank promotional products can reach up to 5%. All deposits up to 50 million KRW per person per institution are protected by the Korea Deposit Insurance Corporation, regardless of bank type.
This guide compares interest rates across bank types and helps you find the best savings account for your situation.
Why Do Interest Rates Vary So Much Between Banks?
Korean banks set their rates based on their operating costs and business strategy.
Key factors driving rate differences:
- Traditional banks have expensive branch networks, so they offer lower rates
- Internet banks operate with minimal overhead, enabling higher rates
- Savings banks (jochuk eunhaeng) offer the highest rates to compete for deposits
- Promotional (teukpan) products provide temporarily elevated rates
As of April 2026, the Bank of Korea base rate is 2.75%. Commercial bank savings rates hover around 3-4%, while savings banks offer 4-5%.

How Do Bonus Rate Conditions Work?
Bonus rates (udae geumni) can add 0.5 to 1.5 percentage points on top of the base rate. Here is how to maximize them.
Easy-to-meet conditions:
- First-time app registration (usually automatic)
- Setting up auto-transfer (once per month)
- Marketing consent (just check a box)
- Issuing a free check card
Harder-to-meet conditions:
- Salary transfer (requires employer cooperation)
- Minimum card spending thresholds
- Signing up for additional financial products simultaneously
Always check the bonus conditions before opening an account. Choose products where you can realistically meet most conditions.
How Do You Calculate After-Tax Interest?
When comparing rates, always think in after-tax terms. Korea withholds 15.4% on interest income.
Example: 300,000 KRW monthly deposits for 12 months at 4.0%
- Pre-tax interest: approximately 78,000 KRW
- Tax (15.4%): approximately 12,012 KRW
- After-tax interest: approximately 65,988 KRW
Ways to reduce the tax:
- Use an ISA account (tax-free up to 2 million KRW in gains)
- Tax-exempt comprehensive savings (for those 65+ or with disabilities)
- Youth housing subscription savings (tax-exempt benefit)

How Do Savings Accounts Compare to Other Options?
Installment savings are not the only way to grow your money in Korea.
When savings accounts are best:
- You cannot tolerate any risk of losing principal
- You want to build a regular saving habit
- You need the money within 1-2 years
Alternatives worth considering:
- CMA accounts: Daily interest with instant access (good for emergency funds)
- Parking accounts: Toss Bank and Kakao Bank offer high rates on demand deposits
- Bond ETFs: Stable returns potentially higher than savings
- ISA accounts with ETFs: Tax benefits plus diversified investing
The most effective approach is combining multiple tools. Keep your emergency fund in a parking account, put regular savings in a high-rate installment product, and invest surplus through an ISA.
What Should You Check Before Opening an Account?
Before opening a savings account in Korea, verify these items.
- Distinguish between base rate and bonus rate
- Confirm you can actually meet the bonus conditions
- Calculate the after-tax interest you will actually receive
- Check the early termination rate (usually only 10-30% of the promised rate)
- Ensure your deposit stays within the 50 million KRW insurance limit
- Set up auto-transfer to avoid missing monthly payments
Pay special attention to early termination penalties. Breaking your savings early dramatically reduces the interest you receive. Only commit amounts you can maintain until maturity.

What is the difference between jeokgeum (installment savings) and yegeum (time deposit) in Korea?
Jeokgeum (installment savings) requires monthly deposits of a fixed amount, while yegeum (time deposit) requires a lump sum upfront. At the same interest rate, a time deposit earns more interest because the full amount is deposited from day one. Choose time deposits if you have a lump sum, and installment savings if you want to build a saving habit.
How much tax is taken from savings interest in Korea?
Interest income tax of 15.4% (14% income tax + 1.4% local tax) is automatically withheld. For example, if you earn 100,000 KRW in interest, you receive about 84,600 KRW. You can reduce this through ISA accounts or tax-exempt savings products if eligible.
Are internet banks in Korea safe?
Yes. Kakao Bank, Toss Bank, and K Bank are all covered by the Korea Deposit Insurance Corporation (KDIC) for up to 50 million KRW per person. This is the same protection level as traditional banks like KB Kookmin or Shinhan.
Can foreigners open a savings account in Korea?
Yes. Foreigners with an ARC (Alien Registration Card) can open savings accounts at most Korean banks. Internet banks like Kakao Bank and Toss Bank also support foreign residents. You will need your ARC, passport, and a Korean phone number.
