When putting your savings to work, first set aside living expenses and planned expenditures. Divide the remaining money based on when you will use it and how much loss you can bear. Interest rate ETFs and TDFs can also lose principal, so decide the purpose of the money before choosing a product.
The allocation ratios and annual return of 6% are assumptions used for calculations, and the tax information also refers to the National Tax Service's guidance dated March 9, 2026.
The Order for Putting Your Savings to Work
Before choosing products, decide how much you can invest. Asset allocation means dividing money among different assets such as stocks and bonds. Your investment period and ability to bear losses should determine the allocation.
- Separate the money needed for daily life. First secure money for living expenses and emergencies.
- Write down when you will use the money. Separate planned expenditures such as tuition, deposits, and home purchase costs.
- Compare products and accounts. Check the possibility of losing principal and the conditions for withdrawing money.
- Set target weights and invest. Start with an amount that will not disrupt your daily life.
- Review the planned and actual weights. Adjust the investment plan if the purpose of the money changes.
If you have loans, first check the interest rate applied to them. Compare the interest saved by repayment with the expected after-tax return from investing. If there is an early repayment fee, include it in the repayment cost.
They use charts and models to discuss an asset allocation strategy.
Conditions Based on the Purpose of the Money
Even for the same lump sum, the appropriate management method varies depending on when the money will be used. If the investment period is short, it is difficult to allow enough time to recover from losses. Make decisions based on your actual spending schedule rather than your age.
| Current situation | What to decide first | Management approach |
|---|---|---|
| A university student with tight living expenses | Money left over each month and tuition payment dates | First consider managing expenses and securing emergency funds |
| Someone with a lump sum who is about to begin military service | Expenses during service and money needed after discharge | Check maturity dates and ease of withdrawal based on when the money will be needed |
| An employee who saves every month | Amount that can consistently be set aside from salary | Consider regular investing only for long-term funds |
| Someone saving for a deposit or home purchase | Schedule for paying the down payment and balance | Prioritize preserving principal and withdrawal timing over price movements |
| Someone preparing retirement funds | Expected retirement date and possibility of interim withdrawals | Consider pension accounts and long-term asset allocation |
Set the size of your emergency fund based on essential expenses and income stability. It should cover necessary expenses even if your income stops temporarily. You can learn about the relationship between the investment period and risk tolerance in Investor.gov's asset allocation guide.
Comparing Deposits, Interest Rate ETFs, and TDFs
Consider deposits for holding money under contractual terms, and funds according to your investment purpose. An ETF is a fund traded on an exchange like a stock. A TDF is a fund that adjusts its asset allocation based on a target date.
| Option | Main purpose to consider | Nature of principal and returns | Conditions to check |
|---|---|---|---|
| Time deposit | Managing the maturity of an existing lump sum | Contracted interest rate applies, and eligible products are protected within the statutory limit | Maturity, early termination rate, protection status |
| Installment savings account | Regularly saving future income | Interest calculated according to how long each payment remains deposited | Payment method, preferential interest rate conditions |
| Demand deposit | Holding living expenses and emergency funds | Interest rate may change, and protection status must be checked for each product | Interest rate tiers, transfer conditions |
| Interest rate ETF | Investment reserve funds seeking short-term interest returns | Performance-based product with possible loss of principal | Tracked benchmark, costs, trading price, settlement date |
| Equity ETF | Growth funds to be managed over the long term | Gains or losses from stock price movements | Investment country, industry, holdings |
| TDF | Long-term funds with a target date, such as retirement | Automatic asset allocation adjustments with possible loss of principal | Target year, stock allocation, total costs |
Deposits and installment savings accounts should not be compared based only on their stated interest rates. Each installment savings payment remains deposited for a different period. Even at the same interest rate, the interest differs from a time deposit in which the entire lump sum is deposited from the beginning.
The protection limit for eligible deposits was raised on September 1, 2025. At the same financial institution, the principal and stipulated interest are combined for each depositor. The limit for ordinary deposits is KRW 100 million.
All principal and stipulated interest on deposits and installment savings accounts held at one financial institution are protected up to a total of KRW 100 million.
This wording comes from the Financial Services Commission's “Everything You Want to Know: Deposits Protected up to KRW 100 Million Starting September 1.” Performance-based products such as funds are not covered by this protection. Check the scope of protection in the Financial Services Commission's guidance dated July 23, 2025.
Conditions to Check When Choosing an Interest Rate ETF
Interest rate ETFs do not guarantee principal like deposits. They are managed in connection with short-term interest rate benchmarks such as CD rates or KOFR. When interest rates change, the pace at which future returns accumulate may also change.
CD stands for certificate of deposit. KOFR is a benchmark interest rate calculated from short-term funding transactions in Korea. Even if a product name includes the term risk-free reference rate, that does not mean the ETF itself is risk-free.
- Tracked benchmark: Check which interest rate the product uses as its benchmark.
- Actual costs: Check trading fees as well as management fees.
- Trading price: Check the bid-ask spread and the difference from net asset value.
- Synthetic structure: Check the risk that a derivatives counterparty may fail to meet its obligations.
- Cash availability: Also check the date when proceeds from a sale can be withdrawn.
Synthetic products use derivatives contracts to replicate benchmark returns. The resulting risks are stated in each product's prospectus. For example, the HANARO KOFR금리액티브 prospectus explicitly states the risks of over-the-counter derivatives.
Criteria for Using TDFs in Pension Savings Accounts and IRPs
Long-term investors who want to reduce the work involved in managing asset allocation may consider TDFs. They generally reduce their stock allocation as the target date approaches. Even with the same target year, risk levels vary by product.
Pension savings accounts and IRPs are accounts that hold money. A TDF is an investment product that can be selected within those accounts. Depositing money into an account does not automatically complete the purchase of a TDF.
| Item to check | What to check |
|---|---|
| Target year | Whether it matches the actual retirement date or time when the money will be used |
| Current asset allocation | Whether the current stock allocation is bearable |
| Allocation adjustment path | How risk changes before and after the target date |
| Costs | How the costs of the TDF and its underlying funds are reflected |
| Existing investments | Whether stock and country allocations overlap with other accounts |
| Account conditions | Which products can be purchased and what the interim withdrawal conditions are |
A TDF does not guarantee principal or living expenses at the target date. Automatic adjustments cannot reflect an individual's spending circumstances. Differences among products are also explained in Investor.gov's 2025 TDF guide.
Before putting money into a pension account, consider whether you may need to withdraw it early. Some interim withdrawals from an IRP are restricted to legally prescribed reasons. Check with the financial institution offering the account about taxes resulting from withdrawals and account termination.
