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.

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

Formula and assumptions

For this restricted case, federal tax is 40% of taxable estate above the 2026 $15 million basic exclusion. Deductions must already be determined under Form 706 rules. No prior adjusted taxable gifts, portability/DSUE, restored exclusion, special credits, nonresident rules, state estate or inheritance taxes, or generation-skipping tax are modeled. Filing obligations can apply even when the estimate is zero. This is a scenario calculation, not a return or estate plan.

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