How this tax calculator works
The Self-Employment Tax Calculator in figflows is designed to give you a fast and practical estimate without requiring an account or sending your data to a server. You can explore different scenarios by changing inputs and immediately seeing how the outputs respond.
We keep the experience static-first and SEO-friendly: the page content is pre-rendered at build time, and only the calculator itself runs on the client. That approach keeps the site fast while still delivering interactive results.
Use this page as a planning tool: start with realistic inputs, then adjust one variable at a time to understand what matters most. If you’re using this calculator for budgeting, it’s often helpful to run a “best case,” “expected,” and “worst case” scenario and compare the deltas.
Quick steps
- Enter your inputs in the form above. You can adjust values to compare scenarios.
- We compute results instantly in your browser (no server calls), so your inputs stay on your device.
- Use the output cards to understand the “headline” result, then review the breakdown/table for details.
Limitations & important notes
Tax rules vary by filing status, jurisdiction, and deductions. This calculator provides an estimate and is not tax advice.
For the most accurate outcome, confirm assumptions (rates, fees, coverage details, and thresholds) against current official sources or provider documents. We’ll continue improving the underlying reference datasets over time.

How to use the estimate responsibly

- Run scenarios: expected year vs. best year vs. worst year.
- Keep a buffer—tax rules and thresholds can change.
- Use the number for budgeting; confirm with a tax professional for filing.
