Definition
- Wang Yongqing's Law holds that one dollar saved is equal to one dollar of net profit — cost reduction adds directly and fully to the bottom line.
Core Idea
- Money saved flows straight to net profit.
- Cutting cost can be as valuable as growing revenue.
- Disciplined saving is a powerful, controllable lever.
How It Works
- Extra revenue carries its own costs, so only part of it becomes profit.
- A dollar of genuine cost saving, by contrast, drops fully to net profit.
- Relentless attention to saving therefore compounds the bottom line.
Usage Example
- A manufacturer that systematically eliminates waste and trims unnecessary costs improves net profit as effectively as if it had won substantial new sales.
Famous Example
- Example: Wang Yongqing, founder of Formosa Plastics, who repeatedly stressed that "one dollar saved equals one dollar of net profit."
- Why it fits this rule: It is his own stated management principle.
- Verification status: Reflects Wang Yongqing's well-known cost-control philosophy.
Use Cases / Situations Where It Applies
- Cost control and efficiency.
- Profitability improvement.
- Operations and lean management.
When Not to Use or Common Misuse
- Do not cut costs in ways that damage quality, growth, or morale.
- Do not pursue saving so narrowly that you starve necessary investment.
- Do not treat all spending as waste; some cost creates value.
