How it works
freelancer overhead calculator takes your inputs and produces monthly taxes, total monthly overhead, net monthly income, overhead percentage. Calculate true overhead costs of freelancing including taxes, insurance, and tools. You provide 6 inputs: Monthly Gross Revenue (currency, in dollars) (default: 8000 dollars); Self-Employment Tax % (percent, in percent) (default: 15.3 percent); Income Tax Rate % (percent, in percent) (default: 22 percent); Monthly Health Insurance (currency, in dollars) (default: 500 dollars); Monthly Tools/Subscriptions (currency, in dollars) (default: 200 dollars); Monthly Retirement Savings (currency, in dollars) (default: 500 dollars). The calculator returns 4 outputs: Monthly Taxes (the primary result); Total Monthly Overhead (a secondary output); Net Monthly Income (a secondary output); Overhead Percentage (a secondary output). Business tax and finance calculations combine multiple moving parts — revenue, expenses, depreciation, tax brackets, and timing — in ways that make back-of-envelope estimates unreliable. This calculator handles the interaction of those variables precisely, so your business decisions rest on real arithmetic. With the default values, monthly taxes is computed from the interaction of every input field — change any one of them and the result updates immediately, so you can stress-test different scenarios without re-entering the whole form. Adjust the inputs to match your real financial situation. The defaults are realistic starting points, but every person's circumstances differ — your actual income, expenses, rates, and timelines will produce a different answer. Use the tool iteratively: start with the defaults, then change one variable at a time to see which factor has the largest impact on your outcome.Tips
- Start with the default values to see a baseline result, then change one input at a time to understand which factor matters most for your outcome.
- Replace every default with your actual number — estimates and rules of thumb produce estimates, not answers. Pull your real figures from pay stubs, statements, or account dashboards.
- Run the numbers quarterly, not annually. Tax brackets, revenue, and expenses shift throughout the year, and adjusting early is far cheaper than correcting at year-end.
