What Is a Washington Wage Garnishment Calculator?

A Washington wage garnishment calculator estimates how much of an employee's paycheck may be withheld for a selected debt or support obligation. It calculates disposable earnings, applies the withholding rules programmed for the selected order type, and displays estimated garnishment amounts, protected earnings, and remaining take-home pay based on the information entered.

Wage garnishment is a process in which an employer withholds part of an employee's earnings to satisfy a debt or legal obligation. The amount withheld can depend on the type of debt, disposable earnings, and applicable wage protections.

The calculator includes consumer debt, medical debt, child support, spousal support, federal student loan administrative wage garnishment (AWG), federal tax debt, a Washington Department of Revenue levy selection, and Chapter 13 plan payments.

It offers three modes: Single order, Stacking, and Payoff timeline. These allow you to estimate withholding for one obligation, model five categories of competing orders, or calculate possible repayment time using a debt balance and annual interest rate.

The calculations follow programmed assumptions that require verification. Results are estimates, not confirmation of what a court, creditor, government agency, or employer must legally withhold.

How the Washington Wage Garnishment Calculation Works

The calculator first determines disposable earnings. It then applies a withholding formula based on the selected order type. For ordinary consumer and medical debts, the model compares 25% of disposable earnings with earnings above its programmed protection floor.

Step 1: Calculate Disposable Earnings

Disposable earnings are gross earnings minus deductions that the calculator treats as legally required.

D=G−min⁡(G,R)D=G-\min(G,R)

Where D represents disposable earnings, G is gross earnings for the pay period, and R is the total required payroll deductions entered.

The calculator includes federal income tax, Social Security and Medicare, mandatory retirement contributions, and other required withholding in its deduction total. It does not include a Washington state income tax field.

If total required deductions exceed gross earnings, the calculator limits them to gross pay. This prevents disposable earnings from becoming negative.

Voluntary deductions, such as health insurance payments, voluntary 401(k) contributions, and dues, do not reduce the disposable earnings base. They are subtracted separately when estimating take-home pay.

Step 2: Calculate the Washington Earnings Protection Floor

For consumer and medical debt withholding, the calculator uses a programmed floor equal to 35 times the federal minimum wage per week. Its encoded federal minimum wage is $7.25 per hour, making the calculated weekly floor $253.75.

F35=35×7.25×52NF_{35}=35\times7.25\times\frac{52}{N}

F represents the earnings protection floor for the selected pay period, and N represents the number of pay periods per year.

The calculator also uses a separate 30-times federal minimum wage floor for federal student loan AWG calculations.

F30=30×7.25×52NF_{30}=30\times7.25\times\frac{52}{N}
Pay FrequencyPeriods Per Year35x Washington Floor30x Federal Floor
Weekly52$253.75$217.50
Biweekly26$507.50$435.00
Semimonthly24$549.79$471.25
Monthly12$1,099.58$942.50

These figures come from the calculator's programmed constants. The calculations use the underlying values before displaying dollar amounts to two decimal places.

For consumer and medical debt, earnings above the Washington protection floor are calculated as follows:

H=max⁡(0,D−F35)H=\max(0,D-F_{35})

H represents disposable earnings above the 35-times floor. When disposable earnings are at or below that amount, H becomes zero.

Calculation clarification: Some static explanatory text in the calculator associates the 35-times floor with $217.50 per week. However, $217.50 equals 30 times $7.25. The actual consumer debt calculation uses the 35-times value of $253.75 per week.

Step 3: Calculate Consumer and Medical Debt Garnishment

For consumer and medical debts, the calculator compares three amounts: 25% of disposable earnings, earnings above the Washington protection floor, and remaining 25% room after entered other garnishments.

C=min⁡(0.25D,H,max⁡(0,0.25D−O))C=\min\left(0.25D,H,\max(0,0.25D-O)\right)

In this formula, C is the calculated withholding ceiling, D is disposable earnings, H is earnings above the 35-times protection floor, and O is the amount entered as other garnishments.

The calculator uses the smallest of these values. If the amount demanded is positive and smaller than the calculated ceiling, the demanded amount becomes the withholding estimate. Entering zero for the amount demanded applies the full calculated ceiling.

The calculator also displays a separate remaining-room figure after subtracting both existing support withholding and other garnishments from 25% of disposable earnings. However, the actual consumer and medical debt formula subtracts only the entered other-garnishment amount.

Step 4: Calculate Child Support and Spousal Support Withholding

The calculator uses separate support withholding percentages instead of the ordinary 25% consumer debt limit.

Csupport=r×DC_{\text{support}}=r\times D

Here, r is the applicable support withholding rate, and D is disposable earnings.

Support SituationCalculator Rate
Supports a second spouse or child50%
Second family supported, with arrears 12 weeks or older55%
No second family selected60%
No second family selected, with arrears 12 weeks or older65%

The calculator selects the rate using its second-family and arrears checkboxes. A smaller positive amount demanded reduces withholding below the applicable ceiling. The result is also limited to disposable earnings.

Step 5: Calculate Federal Student Loan Garnishment

For federal student loan administrative wage garnishment, the calculator uses the smaller of 15% of disposable earnings and earnings above the 30-times federal minimum wage floor.

Cstudent=min⁡(0.15D,max⁡(0,D−F30))C_{\text{student}}=\min\left(0.15D,\max(0,D-F_{30})\right)

D represents disposable earnings, and F represents the 30-times federal floor for the selected pay period. A smaller positive amount demanded further reduces the estimated withholding.

This calculation uses the 30-times floor rather than the 35-times Washington consumer debt floor.

Step 6: Calculate Federal Tax Levy Withholding

The calculator estimates a federal tax levy exemption using stored annual deduction figures for the selected pay year and filing status, plus programmed adjustments for dependents and age-65 or blindness selections.

E=S+(5300×d)+(1600×a)NE=\frac{S+(5300\times d)+(1600\times a)}{N}

E represents the estimated exempt amount per pay period, S is the stored annual deduction amount, d is the number of dependents, a is the number of selected age-65 or blindness boxes, and N is annual pay periods.

The calculator includes stored deduction values for 2024, 2025, and 2026. Its $5,300 dependent adjustment and $1,600 age-or-blindness adjustment are built-in assumptions, not independently verified IRS levy allowances.

The modeled amount available for the federal tax levy is:

CIRS=max⁡(0,D−E)C_{\text{IRS}}=\max(0,D-E)

A positive exempt-amount override replaces the calculated per-period exemption. A smaller positive amount demanded reduces the withholding estimate. The ordinary 25% consumer debt ceiling does not cap this federal tax calculation.

Step 7: Calculate Chapter 13 Plan Withholding

For a Chapter 13 plan, the calculator converts the entered monthly plan payment into an amount for the selected pay frequency.

Cplan=min⁡(D,12MN)C_{\text{plan}}=\min\left(D,\frac{12M}{N}\right)

M represents the monthly plan payment, N represents annual pay periods, and D is disposable earnings. The calculation cannot exceed disposable earnings. A smaller positive amount demanded can reduce it further.

Washington state tax levy limitation: The single-order menu includes a Washington Department of Revenue levy selection, but the code does not implement a separate calculation branch for that selection. Instead, it falls through to the Chapter 13 monthly plan calculation. With the default monthly plan payment of zero, the result is zero withholding. This should not be treated as a reliable standalone Washington state tax levy estimate. Stacking mode handles entered state tax requests separately.

Worked Example: Weekly Consumer Debt Garnishment

Suppose a Washington employee enters the following hypothetical paycheck information:

  • Gross weekly earnings: $350.00
  • Required payroll deductions: $50.00
  • Voluntary deductions: $0.00
  • Other garnishments: $0.00
  • Order type: Consumer debt
  • Amount demanded: $0.00, applying the calculator's full ceiling

First, calculate disposable earnings:

D=350−50=300D=350-50=300

Next, calculate 25% of disposable earnings:

0.25×300=750.25\times300=75

Then calculate earnings above the Washington weekly protection floor:

300−253.75=46.25300-253.75=46.25

Because $46.25 is smaller than $75.00, the earnings-floor restriction controls the estimate. With no other garnishments or voluntary deductions, the calculator produces the following results:

  • Withheld per week: $46.25
  • Estimated annual withholding: $2,405.00
  • Estimated weekly take-home pay: $253.75
  • Share of disposable earnings withheld: 15.42%

This example illustrates the calculator's actual arithmetic. It does not determine whether an employer may legally withhold that amount in a specific situation.

How the Debt Payoff Formula Works

Payoff mode estimates repayment time using the entered debt balance, annual interest rate, calculated periodic withholding, and pay frequency.

The calculator first converts the annual percentage rate into a periodic interest rate:

i=r100Ni=\frac{r}{100N}

Here, i is interest per pay period, r is the entered annual interest rate as a percentage, and N is annual pay periods.

When the interest rate is positive and the periodic payment exceeds accruing interest, the calculator estimates the required number of whole payment periods using:

n=⌈−ln⁡(1−BiP)ln⁡(1+i)⌉n=\left\lceil\frac{-\ln\left(1-\frac{Bi}{P}\right)}{\ln(1+i)}\right\rceil

B represents the balance owed, P is withholding per period, and n is the number of payment periods rounded upward. With zero interest, the calculator instead rounds the balance divided by the periodic payment upward.

For positive-interest calculations, the tool estimates total paid by multiplying the number of periods by the full periodic payment. Estimated interest equals that total minus the original balance. This simplified method does not adjust the final payment to the exact amount outstanding. With zero interest, total paid equals the original balance.

The calculator displays an explanatory message instead of a positive payoff timeline when the balance is zero, withholding is zero, or the payment cannot cover accruing interest.

How to Use the Washington Wage Garnishment Calculator

  1. Select the calculation mode. Choose Single order, Stacking, or Payoff timeline.
  2. Choose the pay year and county. Select 2024, 2025, or 2026, then choose an available Washington county option.
  3. Choose your pay frequency. Select weekly, biweekly, semimonthly, or monthly.
  4. Enter gross pay. Provide your earnings for one pay period, including applicable bonuses and commissions.
  5. Enter required payroll deductions. Include federal income tax, Social Security and Medicare, mandatory retirement, and other required withholding. Enter voluntary deductions separately.
  6. Select an order type. Choose the debt, support, tax, student loan, or Chapter 13 category you want to examine.
  7. Enter withholding information. Provide the amount demanded per period, support already withheld, and other garnishments where applicable.
  8. Complete additional fields. Support orders provide second-family and arrears checkboxes. Federal tax provides filing details and an exemption override. Chapter 13 provides a monthly plan payment field.
  9. Enter stacking or payoff information if needed. Stacking mode provides separate requested amounts for five order categories. Enter a positive debt balance for a meaningful payoff calculation and review the annual interest rate.
  10. Calculate the estimate. Check the required acknowledgment and select Calculate. Use Reset to restore the starting input values.

The primary result displays estimated withholding per pay period for the selected single-order category. The detailed results show disposable earnings, protected income, withholding ceilings, estimated take-home pay, and the percentage of disposable earnings withheld.

Stacking mode additionally displays a priority waterfall and payoff panel based on combined withholding. Payoff mode displays repayment estimates based on the selected single-order withholding amount.

The calculator requires a county selection, gross earnings greater than zero, and the acknowledgment checkbox. It checks numeric inputs against configured minimum and maximum values. The annual interest-rate input accepts values from 0% to 40%, with 12% entered by default. That default is a programmed assumption, not confirmation of the applicable interest rate for a particular debt.

Understanding Your Wage Garnishment Results

Estimated Withholding and Take-Home Pay

The main withholding result represents the amount calculated for one pay period. The tool also displays weekly and annual equivalents based on the selected pay frequency.

Estimated take-home pay is calculated by subtracting required deductions, voluntary deductions, and calculated withholding from gross earnings. If the result is negative, the calculator displays zero.

Dollar amounts are displayed with two decimal places. The share of disposable earnings withheld appears as a percentage with two decimal places.

A colored meter illustrates the withholding percentage against a 65% reference scale. Its color changes at 10% and 25%. These thresholds are visual settings, not separate legal determinations.

How Stacking Mode Handles Multiple Garnishments

Stacking mode models five withholding categories in this programmed order:

  1. Support withholding
  2. Federal tax withholding
  3. Washington Department of Revenue withholding
  4. Federal student loan AWG
  5. Consumer debt withholding

The calculator starts with disposable earnings and subtracts the calculated withholding after each category. Support uses its selected percentage ceiling. Federal tax uses earnings remaining above the estimated IRS exemption.

The Washington Department of Revenue step uses the smaller of the requested state-tax amount, 25% of original disposable earnings, and remaining disposable earnings. The student loan step uses the smaller of its requested amount and its 15% or federal earnings-floor ceiling, calculated from original disposable earnings. Consumer debt withholding then uses its calculated ceiling and any positive earnings remaining.

Important stacking limitation: The student loan step does not separately restrict withholding to the amount remaining after earlier orders. Certain combinations can therefore produce total modeled withholding above disposable earnings. The calculator limits displayed take-home pay to zero, but the waterfall should not be treated as an official legal priority allocation.

How Existing Garnishments Affect the Result

The calculator displays remaining 25% room after subtracting existing support withholding and other garnishments from 25% of disposable earnings, with a minimum of zero.

However, the actual single-order consumer and medical debt formula adjusts its available 25% room using the entered other-garnishment amount only. Existing support withholding affects the separately displayed room figure rather than directly reducing the calculated withholding for that order.

Support, federal tax, student loan, and Chapter 13 calculations use separate formulas. The displayed remaining-room amount therefore does not control every withholding category.

What the County and Pay Year Selections Change

County selection supplies Washington Superior Court venue information in the result notes. It does not change the calculator's numerical withholding limits. The menu includes named counties and an option for other Washington counties.

The pay year determines which stored annual deduction figures are used in the federal tax exemption estimate. The calculator's general withholding percentages and encoded minimum-wage-based floors remain the same across its available years.

Important Legal and Calculation Limitations

The calculator includes informational notes about Washington garnishment limits, court venue, exemption claims, employment protections, and post-judgment interest. These notes reflect programmed assumptions and do not establish an individual's legal rights, deadlines, or eligibility for an exemption.

Actual withholding may depend on the garnishment order, applicable exemptions, current laws, agency instructions, other collection actions, and payroll circumstances. The calculator's legal references, tax exemption values, state-tax handling, and interest assumptions require independent verification.

Because the results are estimates, they should not replace instructions from the relevant court or collecting agency or advice from a qualified Washington attorney.

Frequently Asked Questions

How much of my paycheck can be garnished in Washington?

For consumer and medical debts, the calculator uses the smallest of 25% of disposable earnings, earnings above its 35-times federal minimum wage floor, and remaining 25% room after other garnishments. Different calculations apply to support orders, federal student loans, federal tax levies, and Chapter 13 payments. The result is an estimate rather than a legally binding determination.

What is the difference between gross pay and disposable earnings?

Gross pay is the full amount earned before deductions. Disposable earnings are what remains after deductions the calculator classifies as legally required. These include entered federal income tax, Social Security and Medicare, mandatory retirement, and other required withholding. Voluntary deductions affect estimated take-home pay but not the disposable earnings calculation base.

Why does the calculator use 35 times the federal minimum wage?

The calculator uses a programmed Washington protection floor of 35 times the federal minimum wage for consumer and medical debt withholding. Its encoded $7.25 hourly rate produces $253.75 per week. Federal student loan AWG uses a separate 30-times floor of $217.50 per week. These are different calculations and should not be confused.

Can child support withholding exceed 25% of disposable earnings?

Yes. The calculator applies separate support withholding ceilings of 50%, 55%, 60%, or 65% of disposable earnings. The rate depends on whether a second family is supported and whether the arrears checkbox is selected. A smaller positive amount demanded reduces withholding below the modeled ceiling.

Does the calculator include Washington state income tax?

No. The calculator does not include a Washington state income tax input. Its required withholding fields cover federal income tax, Social Security and Medicare, mandatory retirement, and other required deductions. It calculates disposable earnings by subtracting these entered amounts from gross pay.

Can the calculator estimate multiple garnishments at once?

Yes. Stacking mode accepts separate requested amounts for support, federal tax, Washington Department of Revenue collections, federal student loans, and consumer debt. It displays withholding by category, total withholding, and estimated take-home pay. Results follow a fixed programmed sequence and should not be treated as an official determination of creditor priority.

How does the Washington wage garnishment payoff estimate work?

The payoff calculation uses the outstanding balance, entered annual interest rate, pay frequency, and calculated periodic withholding. It estimates payment periods, approximate calendar time, total paid, and interest. When the payment is zero or cannot cover accruing interest, the calculator displays an explanatory message instead of a positive repayment timeline.
