Methodology

How the calculations work

The calculators use plain arithmetic and the numbers you provide. They do not look up your payroll, location, or tax records.

Shift calculator

Gross pay equals hourly pay multiplied by paid shift hours, plus tips or bonuses.

Money kept equals gross pay minus the estimated tax amount and work-related costs.

Total committed time equals paid shift time plus unpaid breaks, commuting, and preparation or recovery time.

Real hourly rate equals money kept divided by total committed time.

Why taxes are entered manually

Actual withholding depends on income, filing status, location, benefits, deductions, and other details. A user-controlled percentage keeps the calculator useful without pretending to produce an exact paycheck.

How to choose inputs

Important limits

Results are estimates for personal decision-making. They are not payroll calculations, tax advice, legal advice, or a prediction that a job will be good or bad. Benefits, stability, flexibility, health coverage, paid leave, safety, and career value may matter even when they are not represented by one hourly number.
