How to use this unemployment benefit calculator
What this calculator does
This calculator creates a historical planning estimate of weekly and cumulative U.S. unemployment payments under the 2020 CARES Act and a hypothetical extension based on the proposed HEROES Act. It combines an estimated state weekly benefit with the former $600 Federal Pandemic Unemployment Compensation supplement, then lays out up to 39 weekly payments. It is useful for reconstructing a 2020 cash-flow scenario, comparing the enacted supplement cutoff with the proposed extension, or checking the scale of pandemic-era income replacement. It does not determine current eligibility, reproduce every state's detailed base-period formula, account for taxes or partial earnings, or provide a present-day claim amount. The U.S. Department of Labor explains the broader role and administration of state unemployment insurance programs.
When to use it
- Rebuild a personal or household cash-flow timeline for part of 2020.
- Compare the enacted CARES supplement period with the longer proposed HEROES schedule.
- Estimate how a state weekly maximum changes total benefits for different earnings levels.
- Create a documented Excel workbook for budgeting, research, or historical analysis.
How to calculate
- The calculator opens with a complete demonstration: California, a $52,000 annual salary, one dependent, and a benefit start date of April 5, 2020. Results and a validated Excel workbook are immediately available.
- Choose your State. The calculator loads an approximate 2020 weekly maximum for that state. Select “Other state / custom cap” when you want to supply your own limit.
- Replace Annual salary last year, Number of dependents, Benefit start date, and, when needed, Custom weekly maximum. Results update live.
- Read the headline totals, review the component cards, and scan the weekly table to see when the $600 supplement is included.
- Select Download Excel to export the current typed inputs and calculated rows. Reset clears the demonstration data, results, and workbook state; Excel remains unavailable until a complete valid scenario is entered again.
Input guide
State is required and selects the approximate weekly cap used by this model. A higher cap can raise the estimated state benefit, but only when the salary-based amount would otherwise exceed the lower cap. A common mistake is treating the selected cap as a guaranteed award; actual state formulas depend on base-period wages and eligibility rules.
Annual salary last year is a required U.S.-dollar amount from $0 to $1,000,000, entered without scientific notation. The demonstration uses $52,000. The model converts salary to average weekly wages, applies a 50% replacement estimate, and caps the result. Higher salary raises the estimate until the cap is reached. Do not enter monthly pay or a single quarter's wages.
Number of dependents is a required whole number from 0 to 20. The demonstration uses 1. Some states historically offered small dependent allowances; others offered none. A higher count affects the result only where the model has a positive allowance. Do not enter household size when only qualifying dependents would count.
Benefit start date is required and must fall between January 1, 2020 and March 31, 2021. The demonstration uses April 5, 2020. It controls which weekly rows overlap the federal supplement windows. Starting later generally reduces the number of supplement weeks. Enter the first eligible benefit week, not the date a payment arrived.
Custom weekly maximum is a USD amount from $1 to $2,000. It is required only when “Other state / custom cap” is selected; otherwise it displays the selected state's cap and does not override it. A higher custom cap can increase the state portion up to the salary-based estimate. Do not use the federal $600 amount as the state cap.
Output guide
CARES Act total is the estimated 39-week sum of the state benefit plus the enacted $600 supplement for eligible weeks through July 25, 2020. Estimated state benefit is the modeled weekly state payment before the federal supplement. CARES weekly peak is the largest weekly payment in the enacted timeline. Proposed HEROES total applies the same $600 supplement through January 30, 2021 for comparison, while Proposed extension difference is the arithmetic gap between the two totals. These are estimates, not agency determinations.
The Weekly payment timeline lists the week-ending date, state benefit, CARES supplement, CARES total, and proposed HEROES total. A zero supplement means the week is outside that policy window. The summary pills repeat the estimated weekly state benefit and the count of supplement weeks in each scenario.
Worked example
With California selected, annual salary of $52,000 implies average weekly wages of $1,000. The model takes 50%, or $500, then applies California's modeled $450 weekly cap, producing an Estimated state benefit of $450. Starting April 5, 2020 creates 16 CARES supplement weeks through July 25. The 39-week state portion is $17,550 and the federal supplement is $9,600, so the displayed CARES Act total is $27,150.00. Extending the $600 supplement across all 39 modeled weeks yields $40,950.00, a difference of $13,800.00.

Current claim rules and application steps remain state-specific, so consult your state workforce agency rather than using this historical estimate for a live claim.
How the estimate is calculated
Estimated weekly state benefit = min(50% × annual salary ÷ 52 + dependent allowance, selected weekly maximum). Weekly scenario payment = state benefit + applicable federal supplement.
The 50% replacement assumption is intentionally simple and conservative enough for planning, but it cannot reproduce the many state-specific base periods, minimum benefits, alternate high-quarter formulas, waiting-week rules, partial-unemployment reductions, or taxable withholding choices. The federal supplement dates are modeled by full benefit weeks ending on Saturday.
Interpretation and limitations
A high result mainly reflects a higher state weekly benefit, more weeks inside a supplement window, or both. A zero federal supplement does not imply a zero unemployment payment; it means only that the modeled week falls outside the relevant federal add-on period. A zero state benefit usually means the annual salary entered was zero. Negative values are rejected, and amounts that would overflow the supported range are not calculated.
This calculator is designed for historical comparison and education. The pandemic programs discussed here have expired. Current unemployment insurance is administered by states under federal oversight, with eligibility and benefit calculations determined by current law and agency practice.
