In Zhejiang Jinhua, if the social security base is 18,000, the amount you can receive varies for different insurances:

1. Pension: The pension consists of basic pension and individual account pension.

• Basic pension: The formula is ​
  ((Averagemonthlywageofon−the−jobemployeesinthepreviousyearintheoverallplanningarea+Myindexedaveragemonthlycontributionwage)÷)×Contributionyears×1%
  . Assuming the average monthly wage of on - the - job employees in Jinhua is ​
  X
  (data needs to be obtained according to the local statistical department of the year), and your contribution years is ​
  n
  , and your contribution index is ​
  ÷X
  (when the contribution base is 18000). For example, if ​
  X=
  and ​
  n=
  years, your contribution index is ​
  ÷=
  . Then the basic pension is ​
  ((+×)÷)××1%=
  yuan.

• Individual account pension: The formula is ​
  Individualaccountbalance÷Payoutmonths
  . The individual account balance is accumulated by your monthly contribution. If you contribute for ​
  m
  months at a rate of ​
  8%
  of the contribution base of 18000, the individual account balance is ​
  ×8%×m
  . For example, if you contribute for 180 months until retirement, the individual account balance is ​
  ×8%×=
  yuan. If you retire at 60 years old, the payout months is 139, then the individual account pension is ​
  ÷≈1864.75
  yuan. The total pension is the sum of the basic pension and the individual account pension, approximately ​
  +1864.75=3664.75
  yuan (the above is only for example, and the actual situation is subject to local policies and real - time data).

2. Medical insurance: A certain proportion of the contribution base will be returned to the personal medical insurance account. In Jinhua, generally, about 2% - 3% of the contribution base will be returned. If calculated at 2%, ​
   ×2%=
   yuan will be returned to the personal medical insurance account every month, which can be used for outpatient medical treatment, purchase of drugs in designated pharmacies, etc.

3. Unemployment insurance: The amount of unemployment insurance benefits has nothing to do with the social security contribution base. It is mainly determined according to the length of unemployment insurance payment and local regulations.

4. Work - related injury insurance and maternity insurance: These two insurances are fully paid by the unit, and individuals do not need to pay. For work - related injury insurance, if a work - related injury occurs, the compensation amount is calculated according to the degree of work - related injury and local compensation standards; for maternity insurance, it provides maternity allowances and medical expenses for childbirth, etc., and the specific amount is also determined according to local policies.

In general, if the social security base in Jinhua is 18000, the pension and the amount returned to the medical insurance account will be relatively high, which can provide better social security in old age and medical treatment. But it should be noted that the specific amount needs to be calculated according to local policies, actual contribution years and other factors.
