Payroll is where the gross on your offer letter becomes the net in your bank account, and the gap can be 25-40% once taxes, benefits, and deductions are taken out. Payroll calculators bridge that gap by breaking out every line of a paycheck: gross, pre-tax deductions, taxable income, federal and state income tax, FICA, Medicare, post-tax deductions, and net pay. We cover hourly, salaried, commissioned, and tipped workers across the U.S., Mexico, Brazil, Argentina, Spain, and the UK. Every formula follows current tax law and runs entirely in your browser so your salary, hours, and personal data never leave the device.
How to choose the right payroll calculator
For W-2 employees in the U.S., the salary calculator converts between hourly, weekly, biweekly, semi-monthly, and monthly compensation, then subtracts federal, state, FICA, Medicare, and pre-tax benefits (401k, HSA, FSA) to show take-home pay. The hourly to salary and salary to hourly calculators handle the conversion in both directions, including overtime. The pay raise calculator shows the impact of a 3%, 5%, or 10% raise on your paycheck, both before and after taxes. The overtime calculator handles time-and-a-half, double-time, and California-style daily and weekly overtime rules. The bonus tax calculator distinguishes supplemental wage rates (22% federal flat for bonuses under $1M) from regular withholding. The commission calculator projects total compensation at different attainment levels.
Hourly, salaried, and overtime
The U.S. Fair Labor Standards Act requires time-and-a-half pay for hourly workers over 40 hours per week. The overtime calculator computes regular and overtime pay for any week. Salaried exempt employees are not eligible for overtime; the salary calculator helps determine if you should be classified as exempt (above $684/week salary threshold) or non-exempt. The time-and-a-half and double-time calculators handle the common 1.5x and 2x multipliers. The tip pool calculator helps restaurants and service businesses distribute tips fairly, including the new 2026 rules around credit card processing fees. The gratuity calculator handles service charges for events, weddings, and contract work. The severance calculator estimates the standard 2 weeks per year of service (or state-specific minimums).
Pay raises, COLA, and inflation
The pay raise calculator shows the impact of a 3%, 5%, or 10% raise, including the take-home difference after taxes. A common trap: a 5% raise is wiped out by 4% inflation, leaving a 1% real increase. The cost-of-living adjustment (COLA) calculator shows the inflation-adjusted change in purchasing power. For union workers, the COLA increase calculator handles bargained wage increases tied to CPI. The salary negotiation calculator gives you a target range based on market data, your experience, and your current compensation. The pay raise percent calculator also handles merit increases, promotions, and counter-offers.
International payroll: Mexico, Brazil, Spain, UK
The Mexico nomina quincenal calculator handles IMSS, ISR, and Subsidio al Empleo withholdings for biweekly payroll. The salario líquido BR (Brazil) calculator deducts INSS, IRRF, and FGTS. The salario líquido Argentina calculator handles Ganancias, jubilación, obra social, and PAMI. The Spain nómina calculator applies IRPF retenciones and Seguridad Social (contingencias comunes, desempleo, formación profesional). The UK PAYE calculator handles personal allowance, basic/higher/additional rate bands, National Insurance (Class 1 employee), and student loan repayments. Each international calculator uses the current year's parameters and handles common deductions: private health insurance, retirement contributions, and union dues.
Methodology, pay frequency, and accuracy
U.S. payroll calculations use the IRS Publication 15-T method: federal income tax is computed per pay period using the percentage method or wage bracket method, FICA is 6.2% on wages up to the Social Security wage base, Medicare is 1.45% with no cap plus 0.9% additional over $200K. State income tax is added for the 43 states that have it. Pre-tax deductions (401k, traditional IRA, HSA, FSA, commuter) reduce the taxable wage base. Post-tax deductions (Roth 401k, health insurance premium, garnishments) come out after tax. Pay frequency is normalized to annual: weekly = 52 periods, biweekly = 26, semi-monthly = 24, monthly = 12. The calculators use the standard conversion; some state-specific nuances (CA SDI, NY PFL, NJ SUI) may require adjustment.

Frequently Asked Questions
How is my take-home pay calculated? ▾
Gross pay minus pre-tax deductions (401k, HSA, FSA) equals taxable wages. Federal income tax (based on W-4 elections and brackets) is subtracted, then FICA (6.2%) and Medicare (1.45%), then state and local taxes. Post-tax deductions (Roth, health premium, garnishments) come out last. The salary calculator shows every line of the calculation.
How much of a raise do I need to keep up with inflation? ▾
Your raise must exceed the current inflation rate (CPI) to maintain purchasing power. If inflation is 4% and you get a 5% raise, your real increase is 1%. The pay raise percent calculator adjusts for inflation to show the real change in your standard of living.
What is the overtime rate? ▾
Under U.S. federal law, non-exempt hourly workers earn 1.5x their regular rate for hours over 40 in a workweek. Some states (California, Nevada, Alaska) have daily overtime rules. The overtime calculator handles both standard weekly and state-specific daily overtime.
How are bonuses taxed? ▾
Bonuses up to $1 million are subject to a flat 22% federal supplemental wage rate (37% above $1M). The bonus tax calculator shows the actual take-home after federal, state, FICA, and Medicare. Some employers use the aggregate method (combining bonus with regular pay) which can result in higher withholding.
How do I convert between hourly and salary? ▾
Multiply hourly rate by 2,080 (40 hours x 52 weeks) for annual salary, or divide annual salary by 2,080 for hourly rate. The salary to hourly calculator does this automatically and factors in unpaid time off. A $50,000 salary equals about $24/hour, or $26.32/hour with 5% PTO accrual.
