# ₩500,000 Monthly Retirement Plan: Pension Savings and IRP

> Contributing ₩500,000 a month to pension savings meets the annual tax credit limit of ₩6 million. Additional IRP contributions and the 30-year accumulation calculation should be considered separately, while taxes on early withdrawals and post-retirement living expenses should be planned together.

## Key Points

- Check your estimated National Pension benefit and retirement pension balance.
- Set your monthly contribution after excluding emergency funds and money you will need soon.
- It is best to divide your contributions according to the tax credit limits for pension savings and IRP.
- Set up automatic transfers and check whether investment products are being purchased within the account.
- Review your asset allocation and fees, and adjust your post-retirement withdrawal plan.

Start preparing for retirement by automatically transferring an amount you can afford into a pension account. A monthly contribution of 500,000 won matches the annual pension savings tax credit limit of 6 million won. Decide on additional IRP contributions based on your available funds.

The tax figures are based on the Income Tax Act effective July 1, 2026.

## Steps to start preparing for retirement

Before opening a pension account, review your current pensions and capacity to save. A monthly contribution of 500,000 won is an example, not a required amount. If you would have to borrow money for living expenses to make contributions, it is reasonable to contribute less.

1. **Review your current pensions.** Check your estimated pension benefit with the National Pension Service. Also record your company’s retirement pension type and accumulated balance.
2. **Set a monthly contribution you can maintain.** Keep emergency funds and money you will need soon separate. Decide how much to contribute to pension accounts from the remaining amount.
3. **Decide how to allocate contributions between accounts.** If you can contribute 500,000 won per month, consider filling the pension savings limit first. If you have additional capacity, check the remaining tax credit allowance for an IRP.
4. **Set up automatic transfers and product purchases.** Depositing money into an account does not automatically purchase investment products. Check whether automatic purchases are supported and review the actual purchase history.
5. **Review your investment and withdrawal plans.** Check your stock and bond allocations and costs. As retirement approaches, also decide when to withdraw money for living expenses.

Compounding means that investment returns are reinvested, expanding the base on which returns are earned. Starting early gives the same amount of money more time to be invested. However, investment results also depend on the contribution amount and actual rate of return. Starting late does not make retirement preparation meaningless.

## Roles of the National Pension, retirement pensions, and private pensions

Retirement living expenses should be assessed by adding together the amounts you will receive from each pension. Whether the National Pension alone is sufficient depends on your expected living expenses. It is better to determine your private pension contributions after identifying any shortfall.

| Category | Nature of funding | What to check |
| --- | --- | --- |
| National Pension | Public pension received based on contribution history | Coverage period, estimated pension benefit, when benefits begin |
| Retirement pension | Retirement benefits funded by the company | Whether it is DB or DC, accumulated balance, who manages the investments |
| Pension additionally funded by the individual | Personal contributions to pension savings and an IRP | Contributions, investment products, costs, withdrawal plan |

IRP stands for individual retirement pension account. It is used both to receive retirement benefits and to make additional personal contributions. Therefore, classifying the entire IRP balance as personal savings can result in double counting. You can review the retirement pension structure in the [Ministry of Employment and Labor’s explanation of the system](https://www.moel.go.kr/retirementpay.do).

## What the National Pension income replacement rate of 43% means

The National Pension income replacement rate of 43% in 2026 does not guarantee that an individual will receive 43%. It is an indicator based on 40 years of coverage at the average income level. The actual pension benefit depends on your coverage period and income history.

The National Pension Service’s pension reform Q&A explains when the rate applies as follows.

> The adjusted income replacement rate applies to coverage periods on or after 2026.1.1.

The previous rules apply to coverage periods through 2025. Therefore, calculating your estimated pension by multiplying your final monthly salary by 43% is inaccurate. The scope of application is provided in the [National Pension Service’s pension reform Q&A](https://www.nps.or.kr/pnsinfo/ntpsklg/getOHAF0104M0.do).

| Item | Application standard | Interpretation |
| --- | --- | --- |
| National Pension nominal income replacement rate | 43% applies to coverage periods from 2026 onward | Distinguish from individual benefit amounts |
| Overall National Pension contribution rate | 9.5% of standard monthly income in 2026 | Workplace subscribers and employers each pay half |
| OECD average mandatory pension contribution rate | 18.8% for an average-wage worker in 2024 | Total mandatory public and private pension contributions |

The OECD figure of 18.8% and Korea’s 2026 contribution rate are based on different years. In the same OECD statistics, Korea’s 2024 contribution rate is 9.5%. You should also check which pension systems are included in each country’s comparison. The figures appear in the OECD’s [Pensions at a Glance 2025](https://www.oecd.org/content/dam/oecd/en/publications/reports/2025/11/pensions-at-a-glance-2025_76510fe4/e40274c1-en.pdf).

You should also avoid claiming that all actual income replacement rates are in the low 20% range. Without the population covered by the statistics and the income standard, it is difficult to apply the figure to an individual. Use your own estimated pension benefit when planning living expenses.

## Comparing pension savings and IRP

If you want to invest directly in ETFs, compare pension savings funds among the available pension savings products. Pension savings insurance has a different investment method and cost structure. Choosing a product based only on the shared name of pension savings may cause you to overlook these differences.

| Comparison item | Pension savings fund | IRP |
| --- | --- | --- |
| Basic tax credit eligible limit | 6 million won per year | 9 million won per year, including pension savings |
| Allocation to equity products | Up to 100% can be allocated to eligible equity funds and ETFs | As a rule, risk assets may account for at most 70% of the balance |
| Partial early withdrawal | Allowed, but taxation depends on the source of the withdrawal | Limited to reasons specified by law |
| Costs to check | Fund and ETF management fees and transaction-related costs | Account management fees and product costs |
| Eligibility | Available even without income | Check whether you are legally eligible, such as an employee or self-employed person |

An IRP has exceptions to the investment limit for products that meet certain requirements. Check the permitted allocation for each product with the financial institution. The comparison of the systems refers to the table in the [National Pension Research Institute’s Pension Forum, Spring 2026 issue](https://institute.nps.or.kr/fileDown.do?atchFileId=FL26001982&atchFileSn=1).

Filling the pension savings limit first is one option. This is because partial withdrawals and investment allocation are relatively flexible. However, the ability to invest the full amount in equity products does not mean that this is the recommended allocation.

## Contribution amounts by situation

If you contribute 500,000 won per month, your annual contribution is 6 million won. Contributing the full amount to pension savings alone still matches the basic tax credit eligible limit. You do not have to split contributions between two accounts from the beginning to receive the credit.

| Savings capacity | Example contribution structure | Annual personal contribution |
| --- | --- | --- |
| Less than 500,000 won per month | Consider starting pension savings with an amount you can maintain | Actual monthly contribution × number of months contributed |
| 500,000 won per month | 500,000 won per month to pension savings | 6 million won |
| 750,000 won per month | 500,000 won per month to pension savings + 250,000 won per month to IRP | 9 million won |
| Irregular income | Add available funds to a small regular contribution | Actual contribution for the year |

A contribution of 6 million won to pension savings and 3 million won to an IRP totals 9 million won per year. To contribute this in equal monthly amounts, you need 750,000 won per month. A plan of 500,000 won per month does not automatically include 3 million won for an IRP.

The basic tax credit eligible limit is 9 million won. The general personal contribution limit is 18 million won per year across all pension accounts. Separate rules should be checked for matters such as transferring ISA maturity proceeds.

## How much can you receive as a tax credit?

The tax credit amount depends on eligible contributions and your income bracket. A tax credit deducts a certain amount from the tax you owe. The amounts below include the effect of local income tax.

| Income condition for the relevant tax year | Credit effect including local income tax | Contribution of 6 million won | Contribution of 9 million won |
| --- | --- | --- | --- |
| Employment income only and total salary of at most 55 million won | 16.5% | 990,000 won | 1,485,000 won |
| Employment income only and total salary of more than 55 million won | 13.2% | 792,000 won | 1,188,000 won |
| In other cases, aggregate income of at most 45 million won | 16.5% | 990,000 won | 1,485,000 won |
| In other cases, aggregate income of more than 45 million won | 13.2% | 792,000 won | 1,188,000 won |

Under the Income Tax Act, the tax credit rates are 15% and 12%, respectively. Total salary is different from the take-home pay deposited into your bank account. A business owner’s aggregate income must also be distinguished from revenue. The income conditions and limits are set out in [Article 59-3 of the Income Tax Act](https://www.law.go.kr/lsLinkCommonInfo.do?chrClsCd=010202&lsJoLnkSeq=1032880515).

You should not assume that the amounts in the table will be refunded in full. If your tax liability is insufficient, you may not receive the full calculated credit. The actual refund is determined after accounting for taxes already paid and other deductions and credits.

## Calculation example: Contributing 500,000 won per month for 30 years

The accumulated amount varies depending on how an annual return of 7% is converted into a monthly return. Assume that 500,000 won is contributed at the end of each month for 30 years. Total principal contributions are 180 million won. Taxes and costs are excluded from the calculation.

| Calculation method | Monthly return used | Calculated balance after 30 years |
| --- | --- | --- |
| When the annual compounded return is exactly 7% | 1.07^(1/12) - 1 | 584,726,302 won |
| When 7% per year is divided by 12 and compounded monthly | 0.07 ÷ 12 | 609,985,498 won |

The balances are rounded to the nearest won. The formula is `500,000 × ((1+r)^360 - 1) ÷ r`. Here, `r` is the monthly return.

The effective annual compounded return under the second method is approximately 7.229%. Therefore, the two calculations do not assume the same annual rate of return. If presenting a calculated result of at least 600 million won, this difference must be disclosed.

An annual return of 7% is a calculation assumption, not a guaranteed return. In actual investing, monthly returns vary. There may also be periods of losses. This accumulated balance cannot be reproduced using only a simple average return.

The calculation does not include reinvestment of tax credit refunds. Investment costs and taxes upon withdrawal must also be accounted for separately. As prices rise, the amount that can be purchased with the same balance decreases.

## Common mistakes: Confusing deposits, investments, and withdrawals

Putting money into a pension account and holding investment products are separate matters. A self-directed account may require you to place purchase orders. Check both your automatic transfer history and product holdings.

- **Making deposits but overlooking investment management:** Check whether the money remains in cash or cash-equivalent assets.
- **Simply increasing the number of ETFs:** Check whether the same stocks and sectors overlap.
- **Assuming bond products cannot lose money:** Bond funds and ETFs can also decline in price.
- **Assuming that partial withdrawals are tax-free because they are allowed:** Check the taxation of each source of withdrawn funds.
- **Increasing living expense loans to avoid closing the account:** Consider adjusting your contribution amount first.

Ordinary early withdrawals from pension savings may be taxed. Taxable amounts include principal for which a tax credit was received and investment returns. The general other income tax rate is 16.5%, including local income tax. Exceptions apply to unavoidable withdrawals under tax law, so check the [Financial Services Commission guidance](https://www.fsc.go.kr/po010105/87144).

To reduce early withdrawals, keep emergency funds outside your pension accounts. It is also better to separate money you will need soon, such as housing funds. A structure that allows you to continue making contributions is the foundation of long-term investing.

## How to turn accumulated savings into living expenses in your 70s

After retirement, calculate the monthly shortfall in living expenses before focusing on total assets. Even with accumulated savings, an appropriate amount of living expenses is not paid automatically. You must determine when to receive each pension and the conditions for withdrawals.

1. **Write down your expected monthly living expenses.** Separate ongoing necessary expenses such as housing and medical costs.
2. **Add up the pension benefits you will receive at the same time.** Check the estimated benefits from the National Pension and retirement pensions.
3. **Calculate the monthly shortfall.** Subtract after-tax pension benefits from expected living expenses.
4. **Plan private pension withdrawals to cover the shortfall.** Check withdrawal requirements and taxes with the financial institution.
5. **Adjust for market conditions and changes in spending.** Review the price volatility risk of money you will withdraw soon.

Living expenses and estimated pension benefits should be compared using the same inflation basis. Directly subtracting future nominal pension benefits from current living expenses distorts the difference. If losses immediately after retirement coincide with withdrawals, it may be difficult for the remaining assets to recover. For this reason, your plan should connect the accumulation stage with the timing of withdrawals.

## FAQ

### Can I still prepare for retirement if I contribute less than 500,000 won per month?
Yes. The monthly contribution of 500,000 won is an example, not a required amount. Start by setting an amount you can sustain, taking living expenses and emergency funds into account.

### Do I have to split the monthly contribution of 500,000 won between pension savings and an IRP?
You do not have to split it. Contributing 500,000 won per month to pension savings amounts to 6 million won per year. This is the basic pension savings contribution limit eligible for the tax credit.

### How much do I need each month to contribute 6 million won to pension savings and 3 million won to an IRP?
If you contribute the same amount each month, you need a total of 750,000 won per month. You can contribute 500,000 won per month to pension savings and 250,000 won per month to an IRP.

### Is the 9 million won tax credit limit the contribution limit for pension accounts?
The 9 million won amount is the basic combined contribution limit eligible for tax credits for pension savings, IRPs, and similar accounts. The standard limit on your own contributions is a total of 18 million won per year across all pension accounts. Separate rules apply to cases such as transferring ISA maturity proceeds.

### If I put 6 million won into a pension account, will I get 990,000 won back?
For that income bracket, the calculated tax credit benefit, including local income tax, is 990,000 won. However, you must have enough tax liability to receive the full benefit. The actual refund depends on taxes already paid and other deductions.

### If I contribute 500,000 won per month for 30 years, is 600 million won guaranteed?
No. If an annual rate of 7% is divided by 12 and compounded monthly, the amount is approximately 609.99 million won. If the annual compounded rate of return is set to exactly 7%, the amount is approximately 584.73 million won. Both are hypothetical figures that exclude taxes and costs.

### Can I invest the entire amount in equity ETFs through pension savings?
In a pension savings fund, you can allocate 100% to eligible equity ETFs. However, the percentage you are allowed to allocate and the percentage suitable for you are not the same. As a rule, an IRP can hold at most 70% in risky assets.

### What taxes apply if I make an early withdrawal from pension savings?
For a typical early withdrawal, the contributed principal for which you received tax credits and the investment earnings are taxable. The tax rate on other income is 16.5%, including local income tax. Exceptions such as unavoidable withdrawals under tax law must be checked separately.

### Does the National Pension income replacement rate of 43% mean 43% of my final monthly salary?
It is not a rate applied directly to your final monthly salary. It is an indicator based on the assumption that you are enrolled for 40 years at the average income level. The actual pension amount depends on how long you were enrolled and your income history.

### If I set up an automatic transfer to the account, will ETFs also be bought automatically?
An automatic transfer alone does not necessarily complete an ETF purchase. Check the financial institution's automatic purchase feature and its settings. Review both the deposit history and the product holdings.

### Can I combine retirement benefits received through an IRP with my personal savings?
You can include them in your total retirement assets. However, if you have already included them in your projected retirement pension amount, be careful not to double-count them. Record the retirement benefits and your own additional contributions within the IRP separately.

### How do I determine how much to withdraw each month after retirement?
Subtract the after-tax amounts you will receive from the National Pension and retirement pension from your estimated living expenses. Then plan your private pension withdrawals based on the shortfall. Make sure the living expenses and pension amounts you compare are based on the same price level.
