## What is a Real Estate Brokerage Fee?

A real estate brokerage fee (officially called 'junggae-bosu' or brokerage commission in Korean law) is the payment made to a licensed real estate agent (gong-in junggaesa) for their intermediary services in real estate transactions such as sales, jeonse (lump-sum deposit leases), and monthly rentals. Commonly referred to as 'bokbi' in everyday Korean, brokerage fees are legally regulated under Article 32 of the Licensed Real Estate Agent Act (공인중개사법) and Article 20 of its Enforcement Rules, which set maximum commission rates based on transaction type and amount.

The brokerage fee is structured as a bilateral payment system — both the seller (or landlord) and the buyer (or tenant) each pay the agent separately. The fee for each party is determined through negotiation within the legally prescribed maximum rate (sanghanyoyul). This means the legal rate is a ceiling, not a fixed charge, and parties can negotiate lower fees within that limit.

A significant reform took effect on October 19, 2021, when the Enforcement Rules were amended to substantially reduce brokerage commission rates, particularly for high-value housing transactions. The maximum rate for housing sales over 900 million KRW dropped from 0.9% to between 0.5% and 0.7%, and lease commission rates were similarly reduced from 0.8% to between 0.4% and 0.6%. This reform was implemented in response to rapidly rising real estate prices that had caused disproportionate increases in transaction costs for ordinary citizens. Currently, all metropolitan cities and provinces across South Korea have adopted these revised national maximum rates in their local ordinances, making the rates effectively uniform nationwide.

Brokerage fees are a mandatory cost consideration in any real estate transaction in Korea. For property purchases, they represent a significant portion of initial costs alongside acquisition tax and registration fees. For jeonse and monthly rental contracts, they add to the practical costs of moving. Understanding the expected brokerage fee before entering a transaction enables more accurate financial planning and budgeting. This calculator helps you quickly estimate the maximum brokerage fee for any type of real estate transaction, including VAT considerations and special rules for monthly rent conversion calculations.

## How to Use the Brokerage Fee Calculator

This calculator lets you estimate brokerage fees in three simple steps, providing instant results with detailed breakdowns.

[Step 1: Select Property Type]
Choose the type of property from the top tab bar. 'Housing' covers apartments, villas, detached houses, multi-family housing, and their associated land, including housing presale rights (bunyang-gwon). 'Officetel' refers to residential-use officetels with a dedicated area of 85 square meters or less that are equipped with essential facilities including a kitchen, flush toilet, and bathing facilities. 'Non-Housing (Commercial)' covers commercial properties such as shops, offices, land, factories, warehouses, and any property not classified as residential.

[Step 2: Select Transaction Type]
Choose the transaction type from the second tab bar. For Housing and Officetel, you can select from 'Sale/Exchange,' 'Jeonse (Lump-sum Deposit),' or 'Monthly Rent.' For Non-Housing properties, only 'Sale/Exchange' and 'Lease' options are available, as the rate structure for commercial properties doesn't distinguish between jeonse and monthly rent.

[Step 3: Enter the Amount]
For Sale/Exchange or Jeonse transactions, enter the transaction amount (sale price or jeonse deposit). For Monthly Rent transactions, enter both the security deposit and the monthly rent amount separately. The input fields automatically format numbers with thousand separators (commas) for easy reading of large amounts.

Once you've completed the inputs, results appear immediately below. The result card displays the brokerage fee, the applied rate percentage, VAT (10%), and the total amount including VAT. For monthly rent transactions, the converted amount (hwansan-aek) used to determine the rate tier is also shown. If a fee cap applies to your transaction, the cap amount is displayed as well.

The calculation source and effective date are shown below the results for full transparency, so you can verify the legal basis for the rates applied.

## Brokerage Fee Calculation Formula

Brokerage fees are calculated using the formula: Transaction Amount × Maximum Rate. Where a fee cap exists, the calculated fee cannot exceed the cap amount.

[Housing Sale/Exchange Rate Table]
• Under 50 million KRW: 0.6% (cap: 250,000 KRW)
• 50 million – under 200 million KRW: 0.5% (cap: 800,000 KRW)
• 200 million – under 900 million KRW: 0.4%
• 900 million – under 1.2 billion KRW: 0.5%
• 1.2 billion – under 1.5 billion KRW: 0.6%
• 1.5 billion KRW and above: 0.7%

[Housing Lease (Jeonse/Monthly Rent) Rate Table]
• Under 50 million KRW: 0.5% (cap: 200,000 KRW)
• 50 million – under 100 million KRW: 0.4% (cap: 300,000 KRW)
• 100 million – under 600 million KRW: 0.3%
• 600 million – under 1.2 billion KRW: 0.4%
• 1.2 billion – under 1.5 billion KRW: 0.5%
• 1.5 billion KRW and above: 0.6%

[Officetel (Residential, under 85㎡)]
• Sale/Exchange: 0.5%
• Lease: 0.4%

[Non-Housing (Commercial, Land, etc.)]
• Sale/Exchange/Lease: Up to 0.9% (negotiable)

[Monthly Rent Conversion Formula]
For monthly rent transactions, a 'converted amount' (hwansan-aek) is calculated by combining the deposit and monthly rent into a single figure to determine the applicable rate tier.
• Converted Amount = Deposit + (Monthly Rent × 100)
• However, if this amount is less than 50 million KRW: Converted Amount = Deposit + (Monthly Rent × 70)

Example: Deposit 30 million KRW / Monthly Rent 500,000 KRW:
• Converted Amount = 30,000,000 + (500,000 × 100) = 80,000,000 KRW
• Applied Rate: 0.4% (50M–100M tier)
• Fee = 80,000,000 × 0.004 = 320,000 KRW → cap of 300,000 KRW applies → Final: 300,000 KRW

[Value Added Tax (VAT)]
A 10% VAT may be charged separately on top of the brokerage fee. However, individual agents registered as simplified taxpayers (gan-i gwaseja) generally do not charge VAT separately. It is advisable to confirm VAT inclusion with the agent before signing the contract.

## Tips for Saving on Brokerage Fees

Here are practical tips and important considerations for managing brokerage fees effectively in Korean real estate transactions.

First, brokerage fees are negotiable. The legally prescribed rates are maximum limits, not fixed charges. You are not obligated to pay the full maximum amount. The Licensed Real Estate Agent Act explicitly states that fees are 'determined through mutual agreement between the client and the licensed agent within the prescribed limits.' For high-value properties or transactions that close quickly, you may have room to negotiate a lower rate.

Second, always request a receipt for brokerage fees paid. Ask for a cash receipt (hyeongeum-yeongsujeung) or tax invoice (segyeom-gyesanseo). This is important because brokerage fees paid during a property purchase can be included as acquisition costs when calculating capital gains tax (yangdo-sodeukse) for a future sale. This effectively reduces your taxable capital gains and results in tax savings.

Third, verify whether VAT will be charged. Corporate brokerage firms and individual agents classified as general taxpayers (with annual revenue above 80 million KRW) will charge an additional 10% VAT on top of the brokerage fee. Individual agents classified as simplified taxpayers typically do not charge VAT separately. Always confirm the VAT status before signing the contract to avoid unexpected costs.

Fourth, be cautious about additional fee requests beyond the brokerage commission. Under the Licensed Real Estate Agent Act, agents may only charge the brokerage fee and actual expenses (silbi) incurred at the client's specific request (such as document issuance fees or certified copy costs). Demanding any other payments or gifts is illegal.

Fifth, pay attention to how the transaction amount is calculated for presale rights (bunyang-gwon) transfers. The transaction amount for brokerage fee calculation includes only the 'payments made to date (down payment + interim payments) plus the premium (ushdon).' The remaining balance payable to the developer is excluded. Overlooking this distinction can lead to overcharging.

Sixth, brokerage fees may also apply when renewing a lease contract. If you renew through the same agent, a fee is payable. However, if the landlord and tenant negotiate a renewal directly without an agent, no brokerage fee is incurred.

Seventh, for officetel transactions, the rate depends on whether the unit is classified as 'residential' or 'commercial.' Only officetels with a dedicated area of 85 square meters or less that have a private kitchen, flush toilet, and bathing facilities qualify for the residential rate (0.5% for sale, 0.4% for lease). All other officetels are subject to the non-housing rate of up to 0.9%.

## Frequently Asked Questions

### Q. What is the difference between 'brokerage fee,' 'bokbi,' and 'junggae-bosu'?

These are all terms for the same thing — the commission paid to a real estate agent. 'Bokbi' (복비) is the colloquial term commonly used in everyday conversation. 'Junggae-bosu' (중개보수) is the official legal term used in the Licensed Real Estate Agent Act (Article 32), meaning 'brokerage compensation received from each party to a transaction.' 'Junggae-susuryo' (중개수수료, brokerage fee) is another commonly used term. While the current law uses 'junggae-bosu' as the standard term, all three expressions are widely understood and used interchangeably in practice.

### Q. Why is a 'converted amount' calculated for monthly rent transactions?

Monthly rent transactions involve two separate amounts — a security deposit and a recurring monthly payment. To determine which rate tier applies, these must be combined into a single reference figure called the 'converted amount' (hwansan-aek). The standard formula is 'Deposit + (Monthly Rent × 100).' However, when this calculation yields less than 50 million KRW, a reduced multiplier is used: 'Deposit + (Monthly Rent × 70).' The lower multiplier for smaller transactions is designed to reduce the fee burden on low-value rental contracts. This converted amount is then matched against the lease rate table to determine the applicable maximum rate and any fee cap.

### Q. Can I negotiate the brokerage fee to a lower amount?

Yes, absolutely. The legally prescribed rates are maximum limits (sanghanyoyul), not mandatory fixed charges. Article 20 of the Enforcement Rules explicitly states that fees are 'determined through mutual agreement between the client and the licensed real estate agent within the prescribed limits.' This means you have every right to negotiate a lower fee. However, requesting an excessively low fee may affect the quality of service you receive, so it's best to negotiate within a reasonable range that reflects the complexity and value of the transaction.

### Q. Is VAT always charged on top of the brokerage fee?

Whether VAT is charged depends on the agent's tax classification. General taxpayers — including corporate brokerage firms and individual agents with annual revenue exceeding 80 million KRW — charge a separate 10% VAT on top of the brokerage fee. Simplified taxpayers (individual agents with annual revenue below 80 million KRW) generally do not charge VAT separately. Tax-exempt agents do not charge VAT at all. Before signing any contract, always confirm with the agent whether their quoted fee includes or excludes VAT to avoid unexpected additional charges.

### Q. How is the brokerage fee calculated for presale rights (bunyang-gwon) transfers?

For presale rights transfers, the transaction amount for fee calculation is based on 'the actual amount involved in the transaction.' Specifically, this means 'payments made to date (down payment + interim payments already paid) plus the premium (ushdon or markup).' For example, if you're transferring presale rights for an apartment with a sale price of 500 million KRW, where you've paid 50 million in down payment and 100 million in interim payments, and you add a 30 million KRW premium, the transaction amount would be 180 million KRW (50M + 100M + 30M). Housing sale rates are then applied to this amount. The remaining balance that the buyer will pay directly to the developer is not included in the brokerage fee calculation.
