Formula Used
The calculator first finds the gross possible payment. It multiplies eligible adults by the adult amount. It also adds qualifying child or dependent amounts based on the selected round.
Gross payment: (Adults × Adult Amount) + (Children × Child Amount) + (Other Dependents × Other Dependent Amount)
For the first and second rounds, the calculator applies a five percent reduction on income above the filing status threshold.
Rate phaseout: Phaseout = max(0, AGI - Threshold) × 0.05
For the third round, the calculator uses a narrow phaseout range. The amount drops proportionally between the start and ending income limits.
Range phaseout: Phaseout = Gross Payment × ((AGI - Start Limit) ÷ (End Limit - Start Limit))
Final estimate: Estimated Check = max(0, Gross Payment - Phaseout)
Possible unpaid credit: Credit Due = max(0, Estimated Check - Prior Payment Received)
Example Data Table
| Round | Status | AGI | Adults | Children | Other Dependents | Prior Paid | Estimated Result |
|---|---|---|---|---|---|---|---|
| First | Single | $70,000 | 1 | 1 | 0 | $0 | $1,700 |
| Second | Married | $155,000 | 2 | 2 | 0 | $1,800 | $600 possible balance |
| Third | Head of Household | $115,000 | 1 | 1 | 1 | $2,000 | Partial payment |
These examples are for demonstration. Final eligibility can depend on official tax records and filing rules.

Stimulus Check Planning Guide
Why the Estimate Matters
A stimulus check amount can change because income, filing status, and dependents affect the final result. A simple payment table may not show those details. This calculator gives a clearer estimate. It separates the gross amount from the income phaseout. That helps users see why a payment may be lower than expected.
Income and Filing Status
Filing status is important because each status has a different phaseout starting point. A single filer usually has the lowest threshold. A head of household filer has a higher threshold. A married joint return usually has the largest threshold. The calculator uses those limits when a standard payment round is selected.
Dependents and Household Size
Dependents also matter. Earlier payment rounds treated qualifying children differently. The third round was broader and included more dependent types. This page lets you enter children under seventeen and other dependents separately. That makes the estimate more useful for mixed households.
Prior Payments and Credits
Some people received less than their estimated amount. Others received a full payment already. The prior payment field helps compare both values. When the estimate is higher than the amount already paid, the calculator shows a possible remaining credit. This is only an estimate. Tax filing rules and official records may still control the final result.
Custom Rule Option
The custom option is useful for planning, testing, or educational content. You can enter your own adult amount, dependent amount, income start point, and income ending point. The calculator then applies a proportional reduction across that range. This helps compare different policy designs or household scenarios.
Using the Output
The output is designed for quick review. The gross amount shows the starting value. The phaseout shows the income reduction. The estimated check shows the final calculated payment. The possible credit due shows the unpaid balance after prior payments. Download options help save the calculation for records, articles, or client notes.
FAQs
1. What does this stimulus calculator estimate?
It estimates a possible stimulus payment using filing status, income, adults, dependents, selected round, and prior payment received.
2. Does this calculator replace official tax guidance?
No. It is only an estimate. Official eligibility, payment records, and final credits depend on tax agency rules and filed returns.
3. Why does income reduce the payment?
Stimulus payments used income phaseouts. Once adjusted gross income passed a threshold, the payment decreased until it reached zero.
4. Which income should I enter?
Enter adjusted gross income from the tax return used for the payment round. This is usually shown on the federal return.
5. Why are children and other dependents separate?
Some rounds only counted qualifying children. The third round allowed a broader dependent amount. Separate fields improve estimate accuracy.
6. What is prior payment received?
It is the amount already paid to the household. The calculator subtracts it to show a possible remaining credit.
7. What does the custom rule do?
The custom rule lets you test your own adult amounts, dependent amounts, phaseout start, and phaseout end values.
8. Can I download the result?
Yes. After calculating, use the CSV or PDF buttons to save the result for review, records, or planning notes.
