Unemployment Benefit Calculator

Archived historical, non-current snapshot — dated July 9, 2026 (2026-07-09). The state weekly-benefit, dependent-allowance, earnings-disregard, and federal supplement scenarios described below may not reflect current unemployment insurance rules. Check authoritative sources for the applicable period before relying on this estimate.

The unemployment benefit calculator estimates gross unemployment payments over a claim period. It starts with a state weekly benefit amount, adds any dependent allowance, subtracts partial earnings above a disregard, adds a selected federal supplement scenario, and multiplies by the number of claimed weeks. It also compares the estimated weekly benefit with prior weekly wages to show a wage replacement rate. The calculator is useful for budgeting and for reconstructing historical pandemic-era scenarios, but it is not an eligibility tool and it does not replace a state unemployment agency determination.

Unemployment insurance is different from the stimulus checks in this batch. The stimulus check calculator, second stimulus check calculator, and third stimulus check calculator model one-time federal payments from 2020 and 2021. Unemployment insurance is an ongoing federal-state system, with state-specific weekly benefit formulas and claim rules. During the COVID-19 emergency, temporary federal programs such as Federal Pandemic Unemployment Compensation and Lost Wages Assistance could add flat weekly supplements. This calculator includes those historical supplement amounts as scenarios, not as current law.

What the calculator asks for

Enter the weekly unemployment benefit from your state monetary determination, online agency estimate, or scenario assumption. Add a weekly dependent allowance if your state provides one and if you want it included. Enter weekly earnings while claiming and the earnings disregard that your state excludes before reducing benefits. Then select a federal supplement scenario: none, CARES Act FPUC at $600 per week, or Lost Wages Assistance at $300 per week. Finally, enter the number of weeks claimed and prior weekly wages for the replacement-rate comparison.

The calculator does not know your state’s base period, maximum weekly benefit, minimum earnings requirement, waiting week, work-search rules, suitable-work rules, or partial-benefit formula. It also does not know whether a federal supplement was available for the exact week being modeled. You supply the inputs, and the calculator applies its visible formula. That makes it transparent for planning, but it also means the source numbers must come from the correct state and date.

Formula used by the calculator

The calculator first calculates how much earnings reduce the state portion:

$\text{earnings reduction} = \max\left(0, \text{weekly earnings} - \text{earnings disregard}\right)$

It then calculates the adjusted state benefit:

$\text{adjusted state benefit} = \max\left(0, \text{state weekly benefit} + \text{dependent allowance} - \text{earnings reduction}\right)$

The selected federal supplement is added after that state adjustment:

$\text{weekly benefit} = \text{adjusted state benefit} + \text{federal supplement}$

The claim-period total is:

$\text{total benefit} = \text{weekly benefit} \times \text{weeks claimed}$

The wage replacement rate compares the weekly estimate with prior weekly wages:

$\text{replacement rate} = \frac{\text{weekly benefit}}{\text{prior weekly wage}} \times 100\%$

If prior weekly wage is zero, the calculator displays a zero replacement rate to avoid division by zero.

Checking the primary result

Suppose a claimant enters a state weekly benefit of $350, no dependent allowance, no weekly earnings, an earnings disregard of $0, the CARES Act FPUC $600 supplement, 13 weeks claimed, and prior weekly wages of $900. The earnings reduction is $0 because there are no earnings. The adjusted state benefit is therefore $350. The federal supplement is $600, so the estimated weekly benefit is $950. Over 13 weeks, the total benefit is $950 times 13, or $12,350. The wage replacement rate is $950 divided by $900, multiplied by 100 percent, which the calculator shows as about 105.6 percent.

Now change the earnings fields. If the same claimant earns $200 in a week and the state disregard entered is $50, the earnings reduction is $150. The adjusted state benefit becomes $350 minus $150, or $200. With no federal supplement, the weekly benefit would be $200. With the $300 Lost Wages Assistance scenario selected, the weekly benefit would be $500. Those results follow the calculator’s simplified subtraction method; many states use more detailed formulas, so verify the official agency calculation before relying on the number.

Historical federal supplement context

The CARES Act created Federal Pandemic Unemployment Compensation, commonly discussed as the $600 weekly supplement for eligible unemployment weeks in 2020. Later, Lost Wages Assistance provided a different temporary supplement structure, commonly modeled here as $300 per week. These programs were tied to emergency dates, federal guidance, state administration, and eligibility categories that are not fully represented by a simple dropdown. Selecting a supplement in this calculator is best understood as a historical scenario switch.

Current unemployment insurance generally returns to state weekly benefit amounts unless a specific federal or state program is active. That is why the no-supplement option is the safest default for ordinary budgeting. For a full household cash-flow plan, combine the estimate with the budget calculator. If you are comparing unemployment benefits with prior pay, the salary calculator and annual salary calculator can help translate wage assumptions. If benefits affect debt affordability, the debt-to-income calculator can put the weekly estimate into a monthly framework.

Taxes, offsets, and practical cautions

The calculator displays gross benefits before withholding or taxes. Unemployment compensation is generally included in federal gross income, although Congress has occasionally created temporary exclusions for specific tax years. State taxation varies. Benefits can also be affected by overpayment recovery, child support intercepts, severance or pension rules, fraud penalties, or agency corrections. If you are planning a household budget, leave room for those adjustments and keep notices from your state agency.

Rules changed quickly during the pandemic and continue to vary by state. Use this calculator to understand the arithmetic of a benefit scenario, not to prove entitlement. Official state determinations, Department of Labor guidance, and IRS tax rules control actual results.

Common mistakes

• Treating the historical $600 or $300 supplement as a current weekly benefit.
• Forgetting to subtract part-time earnings above the disregard.
• Entering prior monthly wages in the prior weekly wage field, which distorts the replacement rate.
• Assuming every state has the same weekly maximum, dependent allowance, or claim duration.
• Budgeting the gross estimate without considering taxes or withholding.
