Play Brasilia Turbo Arcade (PT)Parametric Calculators Inside Deep Studies
Adjust monthly revenue, creditable input share, and headline VAT rate to compare net tax burden against the legacy cumulative services regime (8.65%) and the 26.5% statutory cap.
Compare monthly household income when taking a formal job and verify that both designs cost the exact same 6 full benefits over 12 months.
Simulate mandatory primary spending share over a R$ 2.30 trillion federal budget base and compare discretionary space for infrastructure and R&D against the OECD benchmark (< 70%).
Compute the primary fiscal surplus required just to stabilize Debt-to-GDP given the real interest rate (r*), real GDP growth (g), and gross debt ratio.
Estimate annual financial drag from surety bonds, bank guarantees, and legal defense on disputed tax assessments vs. the OECD norm.
Measure whether your AI agent generates real operating margin after accounting for failed runs that escalate to human operators (paying twice).
See what happens to real-world SLA when synchronous microservices chain together on your critical path, and how much asynchronous decoupling saves.
