This calculator is for educational purposes and uses flat rates you provide. Real tax systems vary by country and may include thresholds, credits, or progressive brackets.

Self-employment taxes cover income tax and social contributions such as pension and health. Because rules differ worldwide, this tool lets you input your own rates to model a realistic scenario. You’ll see how income, expenses, deductions, and taxes interact—and what percentage each consumes.

What this calculator does

  • Inputs: Gross income, business expenses, other deductions, and three adjustable tax rates (income, social/self-employment, local/regional).
  • Outputs: Net profit, taxable base, total taxes, and estimated take‑home pay.
  • Visualization: A 3D‑styled doughnut chart to quickly grasp your percentages.
  • Global-first design: Works for any country by using your own effective rates.

How to select effective rates

  • Income tax rate: Use your average/expected rate after allowances and credits.
  • Social/self-employment: Add up pension, social security, health fund, and similar contributions.
  • Local/regional: Include municipal or provincial taxes where applicable.

Tips for students and professionals

  • Students: Track small expenses; deductions can materially lower your taxable base.
  • Freelancers: Keep a separate business account to simplify expense tracking.
  • Consultants: Estimate quarterly payments by applying total tax percentage to net profit.
  • Creators: Consider equipment, software, and education as potential deductible expenses.

Limitations

  • Flat-rate model: Real systems often use progressive brackets and credits.
  • Deadlines & filings: Payment schedules vary; always check your local authority.
  • Advisory: For decisions, consult a qualified tax professional in your country.
