Free Child Tax Credit Estimate calculator with clear step-by-step results.
Multiplies the per-child credit by the number of qualifying children, then applies the income phase-out in whole thousand-dollar steps as the statute requires. The refundable cap limits how much of the credit can come back as a refund when it exceeds your tax liability.
Phase-out reduction
Reduction = ceil((MAGI - threshold) / 1,000) x loss per $1,000
Estimated credit
Credit = children x credit per child - reduction, floored at zero
Tax estimate only. Credit amounts, thresholds, refundable caps and eligibility tests change with legislation and differ by filing status and jurisdiction. Confirm with current tax guidance or a qualified preparer.

No. It is the ceiling on how much credit can exceed your tax liability, and it also depends on earned income. Your actual refund depends on withholding and every other item on the return.
