How this calculator works
Taxable profit = revenue - deductible expenses. Estimated tax = taxable profit x combined user-entered tax rates. After-tax profit = taxable profit - estimated tax.
Taxable profit = revenue - deductible expenses. Estimated tax = taxable profit * (federal + state/local + self-employment reserve rates).
Inputs explained
Revenue and volume
The sale, customer, invoice, or workload amount being modeled.
Rates and fees
Editable percentages, flat fees, or tax rates used in the estimate.
Costs
Direct expenses, platform fees, labor, support, or other assumptions that reduce profit or take-home pay.
Understanding your results
Estimated total tax is a reserve planning number, not a filing result. Owner draws do not necessarily change taxable profit in this simplified model.
Example scenarios
Planning example
$180,000 revenue and $45,000 expenses at a combined 34% reserve creates a $45,900 estimated tax reserve.
