Is it cost-effective to buy social security at the age of 30 and pay 280 in January?

Yes, of course it's a good deal. After all, you only paid a small amount of money.

Well, the minimum payment period of endowment insurance is 180 months, which is 15 years. You can give more, and then you can get more. At the same time, the pension insurance can accumulate payment years, that is, intermittent payment is allowed.

You can apply for a pension when you reach retirement age.

Retirement, there is such a formula to calculate pension: the sum of social wage *20%+ personal account *1120, which is obviously directly related to social wage and the amount paid by individuals.

How much to receive depends on the comprehensive factors such as payment time and grade, job type and whether to continue to pay.

In addition, let me help you analyze it: after all, China is a populous country, and the purpose of social security is to solve the future pension and medical care problems and embody the principle of socialist homogenization, rather than widening the gap and creating contradictions, so even if you pay more, you set an upper limit.

If you want to improve the quality of old-age care, I suggest you buy some commercial insurance as a supplement based on social security and your actual economic situation.
