Korea Signboard Production and Removal Cost Calculator

Enter width and height in metres: 400 cm by 100 cm becomes 4 m by 1 m.
One-face area is width × height.
Total billed production area multiplies this by billed faces and identical sign count.
Confirm whether both sides of a projecting sign are already included in the quote.
Legal screening uses one face of one sign, independently of the billed face and sign counts.

For channel letters quoted by character size or count, choose whole-job production pricing and enter the combined production amount.
Area pricing suits identical signs with the same dimensions and unit rate.
Calculate different specifications separately.

Quotation styles are commercial descriptions, not statutory categories.
An LED product may have covered or exposed light sources and fixed or changing content.
Select the actual legal form and lighting method separately when screening permits.

New upfront costs include production, installation labor, work at height, electrical work and confirmed official fees.
If an old sign exists, its current dismantling and restoration estimate is added once.
If a single lifting visit covers both removal and installation, allocate that package once rather than repeating the same equipment charge.

Takeover includes any acquisition payment, refitting and vinyl replacement, installation, lifting, electrical repairs and official charges.
It excludes complete current dismantling.
Confirm ownership, physical condition, design rights and change procedures before treating reuse as feasible.

Current removal has four whole-job inputs: labor, lifting equipment, waste disposal and wall restoration.
These amounts are not multiplied again by area, faces or count.
Disable the existing-sign option when no old sign exists; takeover and current-removal scenarios are then excluded while entered quotes remain available if the option is restored.

Choose final tax-inclusive amounts when VAT is already included.
For taxable net private-service quotes, the calculator adds the 10% rate under VAT Act Article 30.
Normalize exempt or mixed-tax packages to verified final amounts before choosing the inclusive mode.
Business classification, input VAT recovery and refunds are outside the model.

For private cost S, variation r, tax multiplier v and official charges A, the low amount is round(S × (1 − r) × v) + A and the high amount is round(S × (1 + r) × v) + A.
Divide the entered percentage by 100 to obtain r.
The multiplier v is 1 for inclusive amounts and 1.1 for taxable net amounts.
Each scenario is rounded to whole KRW; rounded future shares are then added.

Enter confirmed permit or report fees, applicable inspection payments and license-tax amounts as the final official total for this job.
No VAT or variation is added to that line.
Private agency services belong in private work costs using their actual tax treatment.

A 10% variation simply tests 90–110% of the private quote.
It is neither a market-price interval nor a statistical confidence interval.
Use 0% for fixed quotations and avoid repeating contingency already included by the contractor.

Enter separate whole-job future removal quotes for the new and inherited signs, including labor, equipment, disposal and wall repairs.
The selected tax basis applies to both.
Weight, structure and attachment can differ, so current removal costs are not automatically copied into future estimates.

When the restoration agreement is confirmed, future costs use the agreed tenant percentage.
Without confirmation, reserves assume 100% responsibility for funding purposes only and deposit figures remain pending.
This does not establish a legal obligation to pay all costs.
Civil Act Articles 615 and 654 provide context; the contract, initial condition and allocation of responsibility require separate review.

Reserve shortfall is the future tenant-share upper bound minus separately saved removal funds, floored at zero.
Savings fund the expense and are not subtracted from the cost comparison.
Upfront plus future is a nominal sum across different dates, not a lifetime model of inflation, discounting, maintenance, electricity or recurring license tax.

In the removal-only scenario, deposit deduction is the smaller of the deposit and tenant share when deposit settlement is selected.
Any excess becomes cash payable outside the deposit.
Direct payment produces zero deduction and a cash payment equal to the tenant share.
Unconfirmed agreements do not produce settlement numbers.
Other claims such as unpaid rent are excluded.

This example teaches the arithmetic and is not a price guide.
One 4 m² face at KRW 200,000 per m² costs KRW 800,000 to produce.
New installation labor of KRW 200,000, lifting of KRW 150,000, electrical work of KRW 100,000 and current removal of KRW 500,000 make KRW 1,750,000 in private upfront costs.
Official charges are assumed to be KRW 50,000.

Takeover refitting of KRW 300,000, installation of KRW 50,000, lifting of KRW 100,000 and electrical repairs of KRW 50,000 make KRW 500,000, plus KRW 20,000 in official charges.
Taxable net quotes and 10% variation yield new upfront costs of KRW 1,782,500–2,167,500 and takeover upfront costs of KRW 515,000–625,000.

Future net removal estimates of KRW 600,000 for the new sign and KRW 500,000 for the inherited sign, with a confirmed 100% tenant share, yield reserves of KRW 594,000–726,000 and KRW 495,000–605,000.
Upfront plus future totals are KRW 2,376,500–2,893,500 and KRW 1,010,000–1,230,000.
With KRW 200,000 saved, upper-bound shortfalls are KRW 526,000 and KRW 405,000.

Current removal of KRW 500,000 becomes KRW 495,000–605,000 after tax and variation.
Under an agreed settlement from a KRW 400,000 deposit, the deduction is KRW 400,000 and additional cash is KRW 95,000–205,000.
Loading the example does not automatically confirm real quotes or an agreement; comparisons and deductions remain conditional.

First confirm whether the location or object falls within Article 3 of the Korean Outdoor Advertising Act.
Unknown scope produces a request for information.
Selecting outside scope does not certify an exemption.
Other forms, roof or freestanding signs, special zones and supporting structures need separate local review.

Under Enforcement Decree Article 4, a wall sign falls in the permit branch if either side is at least 10 m or it carries third-party advertising on the fourth floor or higher.
When those permit branches do not apply, Article 5 screening checks a one-face area of at least 5 m² or a location on the fourth floor or higher.
Vertical displays beside an entrance have an area exception, not a blanket exception from the floor rule.

Projecting signs fall in the reporting branch if their top is below 5 m, one face is below 1 m², or they are statutory medical, pharmacy, barber or beauty markers.
A general projecting sign at exactly 5 m with exactly 1 m² is outside those size exceptions.
Banners enter the reporting branch.

Fixed advertising with directly exposed neon or electronic light sources, and digital advertising with changing content, first enter the electrical-advertising permit branch.
The sales name LED does not establish that exposure method.
This is partial national screening, not approval or a guarantee of lawful installation.
Confirm changes of business name or displayed content on inherited signs with the local authority.

For a new shop, compare the quoted cost of a new appearance with the initial cost of takeover.
A lower entered range does not promise better design, increased revenue or safe reuse.
Confirm physical condition and whether the sign can display the intended business identity first.

For closure, distinguish the contractor invoice, the agreed tenant share and the amount settled from the deposit.
Photographs before and after work, the lease, quotes and receipts help keep the agreed restoration scope clear.

A vacant frontage, a vinyl-only refit and a closure involving cladding repairs need different work.
Mark unnecessary items as zero only after confirmation.
Unknown items need quotes.
Discuss safe access, waste handling, landlord consent and shared-building areas with the contractor and building manager.

Q.
Does selecting another sign style change the price? A.
No.
Style records specifications; you enter actual prices.
Character-based channel-letter quotes can use whole-job pricing.

Q.
Is a small sign exempt from reporting? A.
Size alone does not establish exemption.
Floor, lighting, location, form and local ordinances matter.
Individual review needed is not an exemption result.

Q.
Does takeover eliminate the future removal reserve? A.
No.
Responsibility and removal costs can remain.
Enter a separate future quote and confirm the agreed tenant percentage.

Q.
Can savings and the deposit be deducted from total costs? A.
Savings provide funding and the deposit is a settlement mechanism.
Neither eliminates the underlying expense.

Q.
Does a lower entered tenant share establish a lawful deduction? A.
No.
The confirmation records your reported agreement; it does not determine legally recoverable costs or a dispute outcome.

Q.
Are annual license tax and electricity included? A.
No.
The comparison covers this job and the entered future removal estimate.
Budget separately for recurring tax, maintenance and electricity.
