Methodology
How TakeHome Grid works
Core calculation flow
The payroll calculators start by annualizing the gross pay and recurring deductions from the selected frequency. Tax and payroll rules are then applied at the annual level before the result is translated back into the requested pay period.
What the tax references include
Each country reference includes updated dates, source notes, tax brackets, payroll taxes, social contribution rules, pension assumptions, and standard assumptions. State or province overrides are used where a separate local page is needed.
What is not modeled
These pages do not attempt to reproduce every local payroll rule, city tax, benefit plan, cumulative withholding method, or employer-specific deduction. The goal is a clear and useful estimate rather than a payroll-system replica.
