In order to apply for a K1 visa or for that matter a K3 visa you need to meet the financial requirements to petition for a us visa. In order to meet this you need to ensure that you are at least 125% of the poverty line.
The poverty line is not the same for all. Your state has its own poverty line and if you are in the US Army then your poverty line is even lower. Note that if you are active military then you only need to make the poverty line unlike non-military applicants.

Federal Means-Tested Public Benefits. To date, Federal agencies administering benefit programs have determined that Federal means-tested public benefits include Food Stamps, Medicaid, Supplemental Security Income (SSI), Temporary Assistance for Needy Families (TANF), and the State Child Health Insurance Program (SCHIP).
State Means-Tested Public Benefits. Each State will determine which, if any, of its public benefits are means-tested. If a State determines that it has programs which meet this definition, it is encouraged to provide notice to the public on which programs are included. Check with the State public assistance office to determine which, if any, State assistance programs have been determined to be State means-tested public benefits.
