Pick a calculator by the question you are asking
Tax questions come first for most freelancers. How much of this year's freelance profit goes to Social Security and Medicare? The Self-Employment Tax Calculator answers that on its own. What is the full bill once federal brackets, state tax, and filing status are added? The 1099 Tax Calculator covers all 50 states and all four filing statuses. How should that bill be split across the year? The Quarterly Tax Estimator lays out the four 2026 payments with due dates and the safe harbor minimum, and the Home Office Deduction Calculator shows whether the simplified method or actual expenses lowers it more.
Pricing and business questions use a different set. The Freelance Rate Calculator works backward from a target income to a minimum hourly rate that already carries the tax load. The Hourly vs Project Rate Calculator tests a fixed quote against the hours the scope will really take. The Freelancer Profit Margin Calculator checks what is left after costs and taxes each month, and the 1099 vs W-2 Comparison Calculator puts a contract offer next to a salaried one, benefits included. Once the work is done, the Free Invoice Generator produces a PDF invoice in the browser with no signup.
How these tools work
Every calculator runs in the browser, shows its steps rather than a single unexplained number, and works without an account or an email address. The tax constants behind them, including 2026 brackets, the standard deduction, and the $184,500 Social Security wage base, come from IRS revenue procedures and SSA announcements and are refreshed each October to November. Each tool links to a paired guide for the rule underneath it; the full set of guides sits at /guides, and the formulas and sources are documented on Methodology.
What the results are and are not
Results are planning estimates for US freelancers, 1099 contractors, and single-member LLC owners, not a prepared return. Every graduated-rate state except Vermont runs its own 2026 brackets; Vermont uses a simplified approximation. Most credits, the Alternative Minimum Tax, S-corp elections, and multi-state situations sit outside the current models.
