Understand every part of your take-home pay
A paycheck is more than gross income minus one tax rate. This guide explains each part of the estimate so you can adapt it to your employment and location.
How the paycheck calculation works
The calculation starts with gross pay for one pay period. Pre-tax deductions and non-taxable allowances reduce taxable income. Primary and regional income taxes use that taxable amount, while social security, pension, health, or Medicare-style contributions use gross pay.
Gross pay - pre-tax deductions = taxable pay
Gross pay - taxes - contributions - all deductions = net paycheckMonthly and annual results are annualized from the selected pay frequency, making different payment schedules easier to compare.
Salary vs. hourly pay
Salary mode divides annual gross salary by the selected number of pay periods. Hourly mode multiplies regular hours by the hourly rate. Overtime uses separate hours and a multiplier, while bonus and commission are added to the current paycheck.
For an accurate hourly estimate, enter only the hours and extra income expected in this specific pay period.
Taxes, contributions, and deductions
The tax fields use effective rates rather than progressive brackets. An effective rate is total tax divided by the relevant income base. A recent payslip or current official payroll estimator is normally the best source.
Pre-tax deductions may include eligible pension, retirement, insurance, or benefit contributions. Post-tax deductions may include loan repayments, garnishments, and other amounts removed after tax. Expand Total taxes in the result card to inspect each tax component.
How pay frequency changes a paycheck
Weekly pay uses 52 periods per year, every two weeks uses 26, twice a month uses 24, every four weeks uses 13, and monthly uses 12. The paycheck amount changes with frequency, but the same annual salary and rates produce the same annualized net estimate.
Using the calculator in any country
Country presets are editable starting points, not official tax tables. Choose a preset or Custom, select a currency, and replace every rate with assumptions appropriate to your country, region, residency, benefits, and tax year.
Progressive brackets, contribution ceilings, personal allowances, and employer-specific rules should be represented through effective rates. Confirm important decisions against current official guidance or a payroll professional.
