Korea Punitive Damages Multiplier Calculator

Compare Korean 3× and 5× statutory total caps, eligibility assumptions, maximum uplifts and claim-based costs using your documented loss.

Compare statutory caps and amounts after costs

1. Case and legal conditions

Product Liability Act Article 3(2) · Statutory total cap 3×

The manufacturer knew the defect, failed to take necessary measures and thereby caused serious harm to life or body. Damage only to the product or property damage alone does not satisfy this enhanced-damages condition.

Statute version effective: 2018-04-19 · Law checked: 2026-09-07 · Official Korean statute

The effective date below identifies the verified current statute version. Check supply or violation dates and transitional provisions for earlier events. Your selections are not court findings.

2. Eligible loss and claim assumptions

Enter your own loss after reviewing evidence and scope. Exclude fines, surcharges, litigation costs and losses of other victims.

You choose these assumptions. Even 1× is not guaranteed; the table also includes a zero award. Do not add multipliers from different laws.

3. Actual cost quotes

The default is a first-instance property claim filed on paper. Enter the confirmed amount for electronic filing or relief. Quotes should include VAT and success fees relevant to your scenario. Zero means not entered, not free.

4. Documents for lawyer review

Statutory considerations differ by law. These checks prepare your consultation; their count does not change the multiplier or estimate success.

Identify the law and check legal conditions and event timing before calculating personal amounts.

Review prior payments, comparative fault, delay interest, statutory damages, cost recovery and enforceability separately. This tool does not predict a court award.

Save the result with loss evidence, governing provisions, event dates and quotes to discuss the claim with a lawyer.

How much can Korean enhanced damages multiply a loss?

Korean enhanced or punitive damages are available under particular statutes with defined conditions.
They are not a general multiplier for every civil dispute.
A headline mentioning a maximum of five times damages does not establish that your transaction, conduct, loss or evidence qualifies.
This calculator helps a victim or small business that has already assessed its loss compare the next step: the statutory total cap and the financial effect of different claim and award assumptions.

The page uses Korean law verified on 2026-09-07 and amounts in KRW.
It covers six statutes and seven branches, separating technical data misuse from other listed subcontract violations.
It does not value the original injury, predict a court decision or apply another country’s punitive-damages rules.
Use the saved assumptions and supporting documents for a lawyer consultation before deciding the actual claim.

The multiple includes the underlying loss

With an eligible loss of KRW 10,000,000 and a 3× cap, the total ceiling is KRW 30,000,000.
The maximum uplift above the underlying loss is KRW 20,000,000.
Do not add another KRW 10,000,000 to produce a total of KRW 40,000,000.
At 5×, the total ceiling would be KRW 50,000,000 and the maximum uplift KRW 40,000,000.

2026 statutory branches and conditions

The following summaries identify the relevant provisions in the verified current statutes.
The underlying transaction must fall within the particular Act, and its exclusions and liability exceptions must be checked.
A larger loss or more serious public reaction does not let a claimant select a more favorable branch.

Defective product · serious personal injury · up to 3× total

Product Liability Act Article 3(2)

The manufacturer knew the defect, failed to take necessary measures and thereby caused serious harm to life or body.
Damage only to the product or property damage alone does not satisfy this enhanced-damages condition.

Personal data loss or breach · up to 5× total

Personal Information Protection Act Article 39(3)–(4)

Intent or gross negligence caused data loss, theft, disclosure, forgery, alteration or damage, and loss to the data subject.
The enhancement does not apply if the controller proves the absence of intent or gross negligence.

Subcontract · listed unfair practices · up to 3× total

Fair Transactions in Subcontracting Act Article 35(2)(1), (3)

A covered subcontract and loss from a violation of Articles 4, 8(1), 10, 11(1)–(2) or 19 are required.
Not every unpaid invoice qualifies.
Proof that the principal contractor lacked intent and negligence excludes liability.

Subcontract · technical data misuse · up to 5× total

Fair Transactions in Subcontracting Act Article 35(2)(2), (3)

A covered subcontract and loss from technical data misuse or disclosure to a third party contrary to Article 12-3(4) are required.
A mere request for data is distinct.
Proof of no intent and no negligence excludes liability.

Agency · Articles 6, 7 or 12 · up to 3× total

Fair Agency Transactions Act Article 34(2)–(3)

The transaction must fall within this Act and the supplier must have caused loss through a violation of Article 6, 7 or 12.
Proof that the supplier lacked intent and negligence excludes liability.

Franchise · listed violations · up to 3× total

Fair Transactions in Franchise Business Act Article 37-2(2)–(3)

A covered franchise and loss to the franchisee from a franchisor violation of Articles 9(1), 12(1)(1) or 12-5 are required.
Proof that the franchisor lacked intent and negligence excludes liability.

Serious accident · intentional or grossly negligent breach · up to 5× total

Serious Accidents Punishment Act Article 15(1)–(2)

A covered serious accident must result from an intentional or grossly negligent statutory duty breach by the owner or responsible management.
Check scope, workplace size, timing and the due-care and supervision exception for corporations or institutions.

The Subcontracting Act Article 35(2)(1) permits up to 3× for its listed violations, while Article 35(2)(2) permits up to 5× for technical data conduct contrary to Article 12-3(4).
An unpaid invoice alone does not establish the technical data branch.
Environmental, patent, wage and other claims outside the supported list should use the other or unidentified-law selection and obtain a separate statutory review.
The absence of a personal result for that selection does not mean no enhancement exists elsewhere in Korean law.

Prepare the inputs before comparing multiples

Eligible underlying loss

Enter your own documented loss that falls within the enhancement provision, in whole won.
Prepare medical receipts, accounting records, evidence of lost business or an expert calculation as relevant.
Whether non-pecuniary harm belongs in the basis, and how comparative fault or benefit offsets apply, requires separate review.
Exclude fines, administrative surcharges, litigation expenses and the losses of other victims from this basis.

Conditions and event timing

Review substantive conditions and temporal applicability separately.
Supply dates, violation dates, the duration of continuing conduct and amendment transition clauses may matter.
The effective date displayed for a current statute version is not necessarily the first effective date of its multiplier.
An earlier incident must not automatically receive today’s cap.
Both selections must assume applicability before personal amounts are shown; neither selection constitutes a court finding.

Claim and award assumptions

The claim multiple determines the assumed amount sought and the stamp-fee basis.
The selected award multiple compares a result within that claim.
You can assume a claim below the statutory cap, but the award selector cannot exceed the assumed claim.
These controls are a planning boundary, not a model of every procedural rule on claim amendments.
Even 1× is not guaranteed, and the comparison also includes a zero-award scenario.

Actual cost quotes

Enter total lawyer charges relevant to the scenario, including VAT, retainers and any success fee that would apply.
Enter service, expert, document preparation and enforcement costs separately as other costs.
If a contract charges different amounts depending on success, adjust the quote and run the comparison again.
Default zeros mean costs have not been entered; they are not evidence that proceedings are free.
Each money field accepts KRW 0–1 trillion.

Formulas and paper filing fees

Keep the claim fixed while changing the outcome

  • Total cap = eligible loss × statutory multiple
  • Maximum uplift = eligible loss × (statutory multiple − 1)
  • Assumed claim = eligible loss × claim multiple
  • Amount after costs = assumed award − stamp − lawyer − other costs

The default stamp reference follows Civil Litigation Stamp Act Article 2 for a first-instance property claim on paper.
Using V as the claim value, apply the following bracket and then the KRW 1,000 minimum and truncation below KRW 100.
For electronic filing, fee relief or a different case structure, select the actual-payment option and enter the amount confirmed by the court.
The tool does not infer a discount or exemption.

Article 2 first-instance paper property-claim stamp brackets
Claim value V in KRWFormula
Below 10,000,000V × 0.5%
10,000,000 to below 100,000,000V × 0.45% + 5,000
100,000,000 to below 1,000,000,000V × 0.4% + 55,000
1,000,000,000 or moreV × 0.35% + 555,000

A 3× claim retains its claim-based stamp reference even when the assumed award falls to 1×.
Reducing the fee automatically to the awarded amount would conceal the cost of seeking a larger claim.
Zero underlying loss pauses personal comparisons; it does not establish a statutory exemption from the minimum filing fee.
The comparison uses the same entered costs for every outcome, so conditional lawyer charges need their own revised calculation.

Worked example: KRW 10,000,000 loss and a 3× claim

Assume the product-liability enhancement conditions and current-law applicability are satisfied.
Enter an eligible loss of KRW 10,000,000 and a 3× claim, giving an assumed claim of KRW 30,000,000 and a paper stamp of KRW 140,000.
A lawyer quote of KRW 2,000,000 plus other costs of KRW 200,000 produces total entered costs of KRW 2,340,000.
These are fictional arithmetic inputs, not market fee averages or a prediction based on similar judgments.

A 2× award assumption

The assumed total is KRW 20,000,000 and the amount after costs is KRW 17,660,000.
Distinguish this from the statutory total cap of KRW 30,000,000.
The maximum uplift above the original loss is KRW 20,000,000, which is a separate measure from the selected award.

Defeat and other award multiples

A zero award produces an amount after costs of −KRW 2,340,000.
At 1× it is KRW 7,660,000, and at 3× it is KRW 27,660,000.
Additional liability for the other party’s litigation costs is outside these figures.
The negative result remains visible because incurred costs do not disappear when a claim fails.

With the same underlying loss, the privacy, subcontract technical data or serious-accident branch has a statutory total cap of KRW 50,000,000.
Assuming a full 5× claim changes the paper stamp to KRW 230,000.
Choosing a branch requires matching the facts to its statute; it is not a way to select the largest number.
Changing the branch resets the applicability selections so an earlier assumption does not silently carry into a different law.

Step-by-step use and practical situations

  1. Identify the case from the contract, incident records or medical evidence, and read the statutory scope and exceptions.
  2. Check supply, violation and loss dates against the relevant amendment and transitional provisions.
  3. Enter eligible loss without duplicate damage or litigation expenses, then choose claim and award assumptions.
  4. Add court-confirmed payments and professional quotes, and examine the zero-award row as well as the higher outcomes.
  5. Print or save the assumptions as a PDF and bring them with your evidence to a lawyer consultation.

Prepare a concrete discussion

A product victim can distinguish repair or property loss from serious harm to life or body before selecting the enhancement branch.
A subcontractor can separate listed unfair practices from technical data misuse and avoid duplicating the same loss.
A franchisee or agency can check the statutory transaction scope and the actual provision allegedly breached.
A privacy claimant should separately review statutory damages and loss-based enhanced damages instead of adding the two automatically.
These distinctions help identify what evidence remains missing before increasing a claim.

Why the evidence checklist does not score a multiplier

Courts consider the factors specified by the relevant law, which can include intent, harm, economic benefit, duration, repetition, financial position and redress.
The detailed lists differ: product liability refers to supply scale and sanctions, privacy includes efforts to recover data, and serious-accident liability includes the duty breached and prevention efforts.
The checklist is a document-preparation aid, not a scoring model.

Checking more boxes does not increase the result, and missing documents do not trigger an invented reduction rate.
Business revenue, victim count and litigation stage are not converted into a court-award probability.
Your selected multiples remain explicit assumptions that can be discussed and changed with counsel.

An amount after costs is not guaranteed cash

The arithmetic assumes full collection of each hypothetical award.
The defendant’s assets, competing creditors, appeals and delay can change actual collection.
Prior payments, insurance recoveries, comparative fault, benefit offsets, delay interest, statutory damages, adverse-party cost exposure and recovery of your own costs require separate review.
Do not deduct a payment from the basis and again from the final result without confirming the legally appropriate treatment.

Frequently asked questions

Does a 5× label mean I will receive five times my loss?

No.
It is a statutory total ceiling under the stated conditions.
Liability, evidence, loss, judicial considerations and collection remain separate issues.

Is a 3× award added on top of the original loss?

In this calculator the multiple includes the underlying loss.
A KRW 10,000,000 basis has a 3× total ceiling of KRW 30,000,000, with a maximum uplift of KRW 20,000,000.

Does property damage from a defective product qualify for 3×?

Product Liability Act Article 3(2) requires knowledge of a defect, failure to take necessary measures and resulting serious harm to life or body.
Property damage alone should not be marked as satisfying that enhancement condition.

When are subcontract damages 3× rather than 5×?

Article 35(2)(1) covers listed violations at up to 3×.
Article 35(2)(2) covers technical data conduct under Article 12-3(4) at up to 5×.
Check transaction scope, the actual conduct and the no-intent and no-negligence exception.

Can I combine different statutes or multiply by the number of victims?

This tool applies one branch to one underlying loss.
It does not add statutory multipliers or multiply your loss by the total victim count.
Duplicate compensation and individual loss scope require separate review.

Can I apply the current cap to an old incident?

Not automatically.
Compare the earlier and current statutes and transitional clauses against the relevant supply or violation dates.
Leave timing unconfirmed until that review is complete.

Why does the zero-award row still show costs?

The model retains the entered filing and preparation costs when an award fails.
If success fees or other charges depend on the outcome, revise those inputs for the relevant scenario.
Additional adverse-party costs are excluded.
