Precision and calculation record

Decimal places in numeric results and text downloads

Rounding changes displayed numbers, not the calculation. Text, fractions, matrices and CSV schedules keep their own formatting. Automatic keeps up to 12 significant digits, with money shown to cents where applicable.

Saved scenario

Save the current answer, then change an input to compare. This clears when you leave.

Formula and assumptions

This is the health-insurance Marketplace definition for one person, not the Roth IRA or Medicare definition. Add only amounts excluded from AGI, without double counting. Do not add Supplemental Security Income (SSI). Household eligibility also depends on whose income must be included; this tool does not calculate a subsidy or determine eligibility.

Automatic precision shows numbers to 12 significant digits. Thousands separators such as 1,000 are accepted; use a dot for decimals.
