NetPayCal answers one question well: how much of your salary do you actually keep?
NetPayCal was started by M. Fahad Usmani, an educator and independent publisher who has spent years building practical tools and study resources for working professionals. Salary offers, raises and job moves all come down to take-home pay, yet most calculators bury the answer under ads or skip the details that change it.
So NetPayCal keeps it simple. Every calculator shows the full tax breakdown, the assumptions it uses and the date it was last updated. Calculations run in your browser, so your salary never leaves your device.
What we cover
- United States: federal income tax, all 50 states and DC, Social Security, Medicare and state payroll contributions.
- United Kingdom: income tax for England, Wales, Northern Ireland and Scotland, National Insurance, pension salary sacrifice and student loans.
Canada, Australia, Ireland and a Gulf end-of-service gratuity calculator are next.
