Which Calculator Number Should You Use?

The calculator may show two very different numbers. They answer two different questions.

  • The green number — “Amount needed in premiums to reach $0 Share of Cost”
    • Use this number when reviewing the insurance-premium choices below. It estimates the additional monthly premium that may reduce countable income to the applicable ABD-FPL limit.
  • The blue number — “Estimated monthly Share of Cost”
    • This estimates the traditional Medically Needy Share of Cost calculation. A person whose countable income is within the ABD-FPL limit may qualify for $0 Share of Cost even though this larger traditional calculation is also displayed.

Important: Do not purchase insurance based solely on the blue Share of Cost number. Compare the premium choices with the green amount, and request verification before applying.

 Step 2 — Select the Monthly Premium Shown by the Calculator

How much insurance premium do you need to reduce your Share of Cost to $0?

Step 3 — Request Verification From Steve

Before applying, send Steve enough information to compare the calculator result with your county paperwork and the available premium choices.

Please include:

  • The green “Amount needed in premiums to reach $0 Share of Cost.”
  • The monthly Share of Cost shown on your county Notice of Action.
  • Your county and ZIP code.
  • Whether you have Medicare Parts A and B.
  • Your Medicare Part B premium and any other insurance premiums you already pay.
  • Whether the issue concerns future months, previous months or both.
  • A copy of the relevant county Notice of Action, when available.

For your protection: Do not email your Social Security number, bank-account number or credit-card information.

Estimate First — County Verification Controls

This calculator provides an estimate for educational and planning purposes. Medi-Cal eligibility can be affected by household size, earned versus unearned income, spousal rules, allowable deductions, program category and information in the county case file. The county Medi-Cal eligibility worker makes the final determination and should issue a written Notice of Action.
