Permanent Disability Insurance Payout Calculator

What is the permanent disability insurance payout calculator?

This calculator estimates the permanent disability benefit payable under a private Korean accident or life insurance policy when an injury or illness leaves a lasting physical impairment. The core formula is simple: disability payout = sum insured × disability payment rate (%). For example, if the accident disability coverage is KRW 100 million and the recognized disability payment rate is 50%, the benefit is KRW 50 million.

The most important number is the disability payment rate. It comes from the disability classification table (janghae-bunryupyo) attached to the Financial Supervisory Service standard policy for life insurance and for illness and accident insurance. That table assigns a rate from 3% to 100% across 13 body regions and 87 impairment items. This tool sums the rates by region, applies the same-region highest-rate rule, deducts any pre-existing disability, and caps the total at 100%.

Korea-based calculator

This estimate is based on the Korean standard-policy disability classification table (2018 revision, current for 2026) and general private-insurance practice. It is not the actual claim decision. Real payment rates depend on a physician’s impairment assessment, the exact wording and edition of your policy, and the insurer’s loss adjustment. Rates, merging, and deduction rules differ by product, so always check your policy schedule and terms.

The disability payment rate and classification table

Representative disability payment rates

The disability payment rate expresses the severity of a permanent impairment as a percentage, and it works as the multiplier for the benefit. Higher rates mean more severe disability and a larger payout.

• Loss of sight in both eyes: 100% / one eye: 50%
• Total hearing loss in both ears: 80% / one ear: 25%
• Severe central nervous system impairment (quadriplegia, etc.): 100%
• Loss of one arm above the wrist: 60%
• Loss of one leg above the ankle: 60%
• Severe spinal (backbone) movement impairment: 40%
• Loss of one thumb: 15% / Prominent facial scarring: 15%

These are representative examples. Actual rates vary with the degree of impairment, the physician’s assessment, and the policy edition (2005 vs. 2018 table). The presets in the tool are editable.

Summing, deduction, and the 100% cap

When several impairments remain, how the rates are combined drives the payout. This calculator applies three rules automatically.

• Different body regions are added together: arm and leg impairments from one accident are summed.
• Same region takes only the highest rate: two impairments on the same arm are, in principle, counted once at the highest rate. When derived or separately assessed impairments qualify, a simple-sum option is available.
• 100% cap: even if the summed rate exceeds 100%, the sum insured (100%) is the payment ceiling.
• Pre-existing disability deduction: if a rate was already recognized on the same region, only the difference is paid this time.

Accident vs. illness disability

Disability coverage is split by cause into accident disability and illness disability. The two are separate contracts with different sums insured, but they use the same disability classification table.

• Accident disability: impairment from a sudden, external, accidental event (traffic accident, fall, industrial injury).
• Illness disability: impairment caused by disease (stroke, cancer, joint disease).

The same rate can therefore yield different benefits depending on whether the cause is accident or illness, because a different sum insured applies. The tool computes each cause separately.

Premium waiver and high-disability riders

Once the disability rate crosses certain thresholds, extra benefits are triggered.

• 50% or more: most products waive future premiums while keeping coverage in force.
• 80% or more: classified as high-grade disability, which can trigger living-cost riders, extra benefits, or annuity-style payouts.
• Below 3%: some products treat this as minor disability and may not pay, so check the minimum-payable threshold in your terms.

How to use

Step 1: Enter the sums insured

From your policy schedule, enter the accident and illness disability coverage amounts. Leave illness at 0 if not covered.

Step 2: Add disability items

Pick a body region and a preset, or type the disability payment rate directly. Add more items for multiple impairments.

Step 3: Set merging and pre-existing disability

Choose highest-rate-only or simple-sum for same-region handling, and enter any pre-existing rate to deduct.

Step 4: Review the result

Check the total estimated payout, the per-cause benefits, the item breakdown, and the premium-waiver and high-disability badges.

Frequently asked questions

Q. How is the disability payout calculated?

A. Multiply the sum insured by the disability payment rate. KRW 100 million at 50% pays KRW 50 million. Rates across different regions are summed but cannot exceed 100%.

Q. How is this different from traffic-accident disability damages?

A. Traffic-accident damages use the McBride loss-of-earning-capacity method and lost income (tort damages). This payout is a fixed insurance benefit from your own private policy, based on the classification-table rate. The two are separate and can both be received.

Q. Are multiple impairments on one region all added?

A. In principle only the highest rate on the same region is recognized. Derived or separately assessed impairments may be summed, so check your policy’s merging clause.

Q. Does the result equal the actual benefit?

A. It is an estimate based on the standard-policy classification table. The real rate depends on the medical assessment, your specific policy, and loss adjustment, so confirm with your insurer.
