Commercial lease revenue defense calculator

This English page translates the Korean commercial lease revenue defense model for rent, deposit, VAT, fixed cost, variable cost, break-even sales, target profit, and lease renewal strategy.

Break-even revenue and safety revenue

The Korean calculator first builds fixed cost from rent, VAT, management fee, owner salary, employee salary, employer social-insurance burden, utilities, communication, insurance, depreciation, other fixed cost, and deposit opportunity cost.

Variable cost is handled as a contribution-margin ratio from material cost, card fees, delivery fees, and other variable costs. Break-even revenue covers fixed cost, while safety revenue adds the selected target monthly profit.

Rent defense and converted deposit

The result shows current profit, safety margin rate, max affordable rent, and max revenue drop rate. These outputs answer whether the store can defend today rent with today sales, and how much revenue decline the business can absorb.

The Commercial Building Lease Protection Act converted-deposit limits reflected in the Korean calculator are Seoul KRW 900 million, capital overcrowding-control area KRW 690 million, metropolitan cities KRW 540 million, and other regions KRW 370 million.

Renewal versus relocation

The model also compares renewal cost against relocation cost. Relocation is not only moving service; it can include brokerage, interior, signage replacement, business downtime, and miscellaneous launch cost.

Use the result before accepting a rent increase. The 5 percent rent-increase cap and 10-year renewal-right concept matter, but the final bargaining position still depends on converted deposit, lease text, arrears, and statutory exceptions.
