The Child SSI (Supplemental Security Income) Calculator is a valuable tool for families who want to estimate their child’s potential SSI benefits. The U.S. Social Security Administration (SSA) provides SSI to children with qualifying disabilities when the household income and resources are within certain limits.

How to Use the Child SSI Calculator
Using the calculator is simple:
- Enter Household Income – Include parents’ wages, self-employment income, and other sources.
- Enter Household Members – Number of parents in the home, number of children, and whether they also receive SSI.
- Enter Eligible Child’s Details – The age of the child and confirmation of disability eligibility.
- Calculate – The calculator applies SSA deeming rules and provides an estimated monthly SSI benefit.
Child SSI Benefit Formula
The formula for SSI involves several steps:
- Start with Parents’ Gross Income
Income includes wages, self-employment, and unearned income. - Apply Income Exclusions
- First $20 of unearned income excluded.
- First $65 of earned income excluded.
- Half of remaining earned income excluded.
Countable Earned Income = (Earned Income − $65 − $20) ÷ 2
- Apply Parent-to-Child Deeming Rules
- A certain portion of parental income is "deemed" to the child.
- Some income is disregarded based on number of children in the household.
- Determine SSI Payment
SSI Payment = Federal Benefit Rate (FBR) − Countable Deemed Income
(The FBR for 2025 is $943/month for an individual, though state supplements may increase this.)
Example 1: Single Parent, One Child
- Parent earns $2,000/month.
- One disabled child, no other children.
Step 1: Income Exclusions
Earned income = $2,000 − $65 − $20 = $1,915
Half excluded → $1,915 ÷ 2 = $957.50 countable earned income
Step 2: Apply Deeming
$957.50 deemed to child.
Step 3: SSI Calculation
$943 (FBR) − $957.50 = Negative → Child receives $0 SSI
Example 2: Two Parents, Two Children
- Parents’ combined income = $2,500/month.
- One disabled child, one non-disabled child.
Step 1: Income Exclusions
$2,500 − $85 = $2,415
Half excluded → $1,207.50 countable earned income
Step 2: Apply Deeming
Allowance for one ineligible child reduces deemed income. After adjustment, deemed income = $700.
Step 3: SSI Calculation
$943 − $700 = $243 SSI payment
Additional Insights
- Household size matters: More children mean more income disregards before deeming.
- Unearned income reduces SSI dollar-for-dollar (after the $20 exclusion).
- State supplements: Some states add extra SSI payments beyond the federal benefit.
- Direct deposits: SSI is usually paid on the 1st of the month.
- Disability requirement: The child must meet SSA’s strict definition of disability for eligibility.
