How this instrument works
Federal Pandemic Unemployment Compensation, or FPUC, was the $600-a-week supplement Section 2104 of the CARES Act laid on top of every state's own weekly unemployment payment, unchanged whether the underlying state check was $120 or $720. Congress fixed the number instead of setting a percentage so state agencies overwhelmed by March 2020's claim volume could add one flat figure to any check already in payment, without recalculating each claimant's prior wage.
Because the boost is additive rather than proportional, its weight on a paycheck depends entirely on how small the state benefit already was. A worker whose state drew $200 a week saw the $600 triple their income; a worker whose state benefit already sat near $700 barely noticed the same flat add-on by comparison. That shape is exactly why a Congressional Budget Office estimate found most recipients collected more from the combined check than their prior job paid — a side effect of choosing a flat number for speed, not a rate tuned to replace lost wages.
The figure this instrument returns covers only the original FPUC period Congress set in Section 2104, roughly the week ending around March 29, 2020 through the week ending July 25 or 26, 2020, depending on how a given state closed its benefit week — the law itself expired the $600 add-on on July 31, 2020. It does not model the smaller $300 supplement FEMA funded separately that August under disaster relief authority, does not withhold tax, and does not check a state's own weekly minimum or cap; enter the weekly state benefit exactly as your state agency approved it.
- Enter Weekly state unemployment benefit, $ — the amount your state agency approved before any federal add-on.
- Set Weeks of benefits received to the number of weeks you actually drew a payment, not a program's maximum.
- Read Total weekly benefit with federal boost, $ — your state amount plus the flat $600 FPUC supplement.
- Check Total benefit received, $ for the full amount across every week entered.
Worked example — $300 a week for 10 weeks
Set Weekly state unemployment benefit, $ to 300 and Weeks of benefits received to 10 — a mid-range state check drawn across ten weeks of the FPUC period. Total weekly benefit with federal boost, $ becomes $300 plus $600, or $900 a week, before the ten weeks are even multiplied in.
Total benefit received, $ then multiplies that $900 weekly figure by the 10 weeks entered, landing on $9,000 for the period. Notice the $600 federal piece alone supplied $6,000 of that total, two-thirds of the check — for a worker whose prior paycheck ran below $900 a week, the combined benefit briefly outpaced the job it replaced, the widely-debated design feature at the center of the original CARES Act supplement.
Questions
Why is the FPUC add-on always exactly $600, regardless of my state benefit?
Section 2104 of the CARES Act fixed the supplement at a flat $600 a week rather than a percentage of prior wages, so it added the identical dollar amount to every claim, whether the underlying state benefit was $150 or $700. Congress chose a flat figure so overwhelmed state systems could add one number to any check already approved, instead of recalculating each claimant's replacement rate.
Which weeks actually qualified for the $600 federal supplement?
Weeks of unemployment roughly between the week ending around March 29, 2020 and the week ending July 25 or 26, 2020, since the exact cutoff followed each state's own benefit-week calendar. Section 2104 itself expired the $600 add-on on July 31, 2020, so no week after that date qualifies, even if a state benefit continued.
Is this the same $600 as the later Lost Wages Assistance payment?
No. Lost Wages Assistance paid a smaller $300 weekly supplement roughly from August into September 2020, funded through FEMA disaster relief rather than the CARES Act, and this site models it separately. The $600 FPUC figure here belongs only to the original spring-to-summer 2020 supplement Section 2104 authorized.
Do I owe tax on the total this calculator shows?
Yes. Both the state weekly benefit and the $600 federal supplement counted as ordinary taxable income, reported to the recipient on Form 1099-G for the year paid, and neither piece had tax withheld automatically unless the claimant elected the optional 10% withholding. This sheet returns the gross figure before any tax.
Why did some people collect more from unemployment than their paycheck?
Because the $600 was a flat add-on rather than a percentage tied to lost wages, it could exceed the gap between a low state benefit and a worker's prior earnings. A Congressional Budget Office analysis found a majority of recipients received more combined benefit than their job had paid, a widely-debated tradeoff of choosing speed and simplicity over precise wage replacement.
Does this account for my state's own weekly benefit cap?
No — enter Weekly state unemployment benefit, $ exactly as your state agency already calculated and capped it. This instrument only adds the flat federal supplement and multiplies by weeks; it does not recompute a state's minimum or maximum weekly amount, which varies widely from roughly $190 to over $800 depending on the state.
