The Self Employed Paycheck Calculator computes income, tax, deduction, and net cash flow values for self-employed individuals by converting revenue, expense, filing status, entity type, tax rates, deduction inputs, and frequency selections into annualized and normalized numeric outputs. The calculator processes inputs through a fixed execution sequence that applies predefined federal tax brackets, standard deduction constants, Social Security caps, percentage-based formulas, and conditional entity logic to produce taxable income, total tax, net pocket, and derived metrics. All outputs are generated solely from arithmetic operations and condition checks defined in the calculation code.
Inputs Used by the Self Employed Paycheck Calculator
The revenue input represents gross business revenue entered in the selected frequency unit. The frequency selector determines whether the entered revenue represents weekly, bi-weekly, monthly, or annual revenue and is used to annualize the revenue by multiplying it by a fixed frequency constant of 52, 26, 12, or 1.
The business expenses input represents total operating expenses in the same frequency unit as revenue. This value is annualized using the same frequency multiplier and subtracted from annual revenue to calculate business profit.
Annual hours worked represents the total number of hours worked per year and is used only to calculate the effective net hourly value by dividing net pocket by total hours.
Filing status selects one of three predefined federal tax bracket tables: single, married filing jointly, or head of household. Each filing status also maps to a fixed standard deduction constant.
State tax rate is a flat percentage applied directly to taxable income after deductions. No brackets or caps are applied to state tax calculations.
The personal burn input represents a monthly personal spending value. This input is converted to an annual value and used only in derived calculations related to burn rate, runway, and comparison outputs.
Health insurance, home office deduction, and retirement contribution inputs represent annual deduction values. These amounts are subtracted at defined stages of adjusted gross income calculations depending on entity type.
The QBI checkbox determines whether a qualified business income deduction is applied. When enabled, a QBI deduction is calculated as a percentage of the qualified income base, subject to a taxable income cap.
Entity type selection switches calculation logic between sole proprietor or LLC treatment and S-Corporation treatment. In S-Corporation mode, an additional salary percentage slider is enabled.
The S-Corporation salary slider defines the portion of profit allocated to W-2 salary as a percentage. The remaining profit after salary and employer payroll tax is treated as distribution.
Saved cash represents total available savings and is used only in vault progress, runway, and buffer calculations.
How the Self Employed Paycheck Calculator Works
The calculation begins by reading the selected frequency and annualizing revenue and expenses using the corresponding multiplier. Annual profit is calculated as revenue minus expenses, with a lower bound of zero enforced.
Home office deductions are subtracted from profit to compute adjusted profit. Entity-specific tax logic is then applied.
For sole proprietor calculations, self-employment tax is computed by multiplying adjusted profit by 0.9235 to determine the self-employment tax base. Social Security tax is calculated as 12.4 percent of this base, capped at the Social Security wage cap of 176,100. Medicare tax is calculated as 2.9 percent of the same base without a cap. The sum of these values forms total self-employment tax.
For S-Corporation calculations, salary is calculated as profit multiplied by the selected salary percentage. Total FICA tax on salary is calculated using the same Social Security and Medicare rates and caps. Half of this amount is assigned as employer payroll tax and half as employee payroll tax. Employer payroll tax is subtracted from profit to determine the distribution amount.
Adjusted gross income is calculated next. For sole proprietors, adjusted gross income equals adjusted profit minus half of self-employment tax, minus health insurance, minus retirement contributions. For S-Corporations, adjusted gross income equals adjusted profit minus employer payroll tax, minus health insurance, minus retirement contributions.
Qualified business income is calculated based on entity type. For sole proprietors, QBI base equals adjusted profit minus half self-employment tax, minus health insurance, minus retirement contributions. For S-Corporations, QBI base equals adjusted profit minus salary, minus employer payroll tax, minus health insurance, minus retirement contributions.
Taxable income before QBI is calculated by subtracting the filing-status-specific standard deduction from adjusted gross income. If QBI is enabled, a potential QBI deduction equal to 20 percent of the QBI base is calculated and limited to 20 percent of taxable income before QBI. The lesser of these values is subtracted from taxable income.
Federal income tax is calculated by iterating through the selected filing status bracket table and applying the marginal rate to the taxable income above each threshold. State tax is calculated as taxable income multiplied by the state tax rate percentage.
Net pocket is calculated differently by entity type. For sole proprietors, net pocket equals adjusted profit minus total taxes, minus health insurance, minus retirement contributions. For S-Corporations, net pocket equals salary minus employee payroll tax, plus distribution, minus federal tax, minus state tax, minus health insurance, minus retirement contributions.
A marginal calculation is executed by rerunning the full logic with revenue increased by 1,000 while holding expenses constant. The difference in net pocket between the two runs is stored as marginal value.
Results and Metrics Explained
Gross revenue represents total annualized business revenue. Expenses represent total annualized operating costs.
Adjusted profit represents revenue minus expenses and home office deductions.
Adjusted gross income represents profit after entity-specific deductions and payroll adjustments.
Taxable income represents adjusted gross income minus the standard deduction and QBI deduction where applicable.
Federal income tax represents the result of applying progressive brackets to taxable income. State tax represents a flat percentage of taxable income. Self-employment or payroll tax represents Social Security and Medicare taxes calculated under the applicable entity rules.
Total tax represents the sum of federal tax, state tax, and self-employment or payroll tax.
Net pocket represents remaining cash after subtracting all taxes and deductions defined in the calculation logic.
Effective hourly value represents net pocket divided by annual hours worked.
Quarterly estimated tax represents total tax divided evenly by four.
Marginal value represents the change in net pocket resulting from an additional 1,000 in revenue.
Interpreting the Calculation Output
Higher revenue values increase profit, taxable income, tax values, and net pocket through proportional and bracket-based calculations. Higher expenses reduce profit and downstream tax calculations. Higher tax rates increase total tax values through direct multiplication. Higher deductions reduce adjusted gross income and taxable income. Higher annual hours reduce the effective hourly value through division. Higher salary percentages in S-Corporation mode shift taxable income between payroll and distribution calculations without altering revenue.
Assumptions and Calculation Limits
Federal tax brackets are fixed to predefined values. Standard deductions are fixed constants by filing status. State tax is calculated as a flat percentage without brackets. Social Security tax is capped at 176,100, while Medicare tax is uncapped. QBI deduction is capped at 20 percent of taxable income before QBI. Expenses are treated as fixed during marginal calculations. No credits, carryforwards, phaseouts, or alternative minimum tax logic are applied.
Estimation Disclaimer
All values are estimates generated from fixed formulas, constants, and user-provided inputs defined in the calculation code. The calculator does not account for jurisdiction-specific rules, credits, or employer-specific payroll adjustments. Actual tax filings and cash flow results may differ from the calculated outputs.
