How much is a person's life worth? When asked this question, some literary and pretentious people would say: a person's life is priceless.

The price can be determined by everyone's willingness. If people are willing to pay 100 USD for this thing, then it is worth 100 USD. How much a society is willing to spend to save a person's life is how much a person's life is worth.

If you ask a society's government how much it is willing to spend to save a person's life, you cannot get an answer. But if you ask how much a society's government is willing to spend to reduce the mortality rate of a problem, it becomes very simple.

Suppose a problem affects 1,000 people, and the government is willing to spend 100,000 USD to solve this problem, reducing the mortality rate by 1%. This represents the value of human life according to the government. That is to say, among 1,000 people, a 1% reduction in the mortality rate means 10 fewer deaths. The government is essentially spending 100,000 USD to save these 10 lives. Then the value of one person's life is

100000/10 = 10000 USD

Assume a problem affects x people, and the government is willing to spend y to solve this problem. Reducing the mortality rate by z means the government spends y to save x*z lives, so the value of one person's life is

y/x/z

In fact, the price of a human life has a term called: VSL (Value of Statistical Life)

The VSL data in the United States is roughly between 5,000,000-13,000,000 USD. Exceeding this, the government would consider the expenditure not cost-effective.
