Washington Child Support Calculator

Consult with a local child support lawyer:

To use the child support calculator, select or enter the appropriate information next to each statement.

When you have completed the form, click on the calculate button to get an estimate of the amount of child support that the non-custodial parent will have to pay to the custodial parent in Washington.

Disclaimer: Please remember that these calculators are for informational and educational purposes only. The amount of child support a court will order for any particular case may be different from the amount estimated by the calculator.

For the most part, these calculators assume that all of the children at issue will primarily live with one parent. They are not intended to estimate child support for joint physical custody or split custody arrangements.

These calculators do not take into account any possible adjustments for children who are not subject to the custody order, but who are living with one of the parents. Finally, these calculators may be based on older or outdated state guidelines or calculations and may not take into consideration state or federal tax implications on income.

These and many other factors can affect a child support order entered by a court.

Common Methods for Enforcing Child Support in Washington

The Washington State Department of Social & Health Services Division of Child Support (DCS) helps families collect child support payments from non-custodial parents who are delinquent in their child support payments. There are a number of methods available to the Washington State Department of Social & Health Services Division of Child Support (DCS) to help enforce child support orders. These collection methods include things like:

Income Withholding
Income withholding is a way to ensure that child support payments are made regularly and in a timely fashion. If a non-custodial parent is not paying their monthly child support obligation, DCS can have their wages garnished.

Income Tax Refund Interception
If a non-custodial parent is behind in their court-ordered child support payments or not paying their monthly child support obligation, DCS may intercept any income tax refunds they may have otherwise been entitled to receive.

License Revocation or Denial
Another way DCS can enforce child support orders is through license revocation or denial. DCS can have professional licenses, driver’s licenses and hunting fishing licenses revoked or denied to any parent who is not fulfilling his or her child support obligation.

Property Liens or Seizures          
A parent who is negligent in his or her responsibility to pay child support may have a lien placed on their assets or even have property seized to pay their child support obligation.

Contempt of Court
In very serious circumstance, a parent may be found in contempt of court and face time in jail for ignoring a child support order.
