How it works
Revenue$8,000
Expenses$1,500
Both taxes$2,247.39
Take-home$4,252.61
The calculator starts with profit, which is revenue minus expenses. It then applies self-employment tax at 15.3% to 92.35% of that profit. The calculator deducts half of that tax before income tax. Income tax uses the rate you enter.
From $8,000 of revenue and $1,500 of expenses, profit is $6,500. Self-employment tax is $918.42. After deducting half of it, $459.21, income tax at 22% is $1,328.97. Take-home is $4,252.61.
The same month, repeated for a year, is $51,031.32 take-home. Three months of the combined tax come to $6,742.17. The calculator does not apply the Social Security wage-base cap, and it does not add the extra 0.9% Medicare tax. 22% is the rate in the example, not a bracket the calculator looks up.
The effective rate is the gap between revenue and take-home, divided by revenue. On this example it is 46.8%. That is not the 22% rate by itself, and it is not a comparison with a job.
Formula
self-employment tax = 15.3% × 92.35% × (revenue − expenses)
Income tax uses the rate you enter, after deducting half of the self-employment tax. Take-home is revenue minus expenses, self-employment tax, and income tax. From $8,000 and $1,500 of expenses, at 22%, take-home is $4,252.61. When expenses are higher than revenue, profit is 0.
One invoice, two taxes
One month of $8,000 in revenue and $1,500 in expenses leaves a $6,500 profit. Self-employment tax on that profit is $918.42. Income tax at 22%, after deducting half of the self-employment tax, is $1,328.97. Take-home is $4,252.61.
The same month, repeated for a year, is $51,031.32 take-home. Three months of both taxes come to $6,742.17. That is the quarterly amount if every month looks like this one. The bar shows how the invoice splits into take-home, income tax, self-employment tax, and expenses.
