Step-by-step derivation 🧩

Annual hours: Hᵧ = H_w × Wᵧ, where H_w is hours/week and Wᵧ is weeks/year.
Gross annual from hourly: Gᵧ = r_h × H_w × Wᵧ.
Reverse hourly from annual: r_h = Gᵧ / (H_w × Wᵧ).
Net using flat rate t: N = G × (1 − t) for any period.
Reverse gross from net: G = N / (1 − t).
Weekly, monthly equivalents: week = year / Wᵧ, month ≈ year / 12.

Reference notes

Annual income = hourly wage × hours/week × weeks/year.
“Net” here uses a single flat rate for simplicity; actual payroll deductions vary by jurisdiction and individual situation.
Monthly conversion uses 12 months/year (approximation for budgeting).
