Methodology

Simplified SaaS operating math. Monthly gross profit = MRR × gross margin %. Monthly operating profit = gross profit − fixed − marketing − contractor/team. Annualised (×12), then the country's headline corporate income tax rate is applied to positive profit only (losses are not taxed). It does NOT model VAT/sales tax, payroll/social charges, transfer pricing, R&D credits, IP-box regimes, or deferred-tax timing. Orientation only, not tax or financial advice.

Country data last updated .

These calculations are informational estimates based on headline rates and transparent assumptions — not tax, accounting, or legal advice. Verify with a qualified local advisor before relying on the results.

Data limitations

  • Payment-provider availability (Stripe, PayPal, Wise) reflects the most recent review and may change over time.
  • VAT figures are standard rates only; reduced and zero rates, registration thresholds, and sector exemptions are not modelled.
  • Estimates use headline rates; your effective rate depends on deductions, incentives, timing, and local taxes specific to your business.
