United States calculators
Free US calculators for 2026: paycheck and take-home pay, federal income tax, and sales tax for every state, plus BMI, loan and more.
American take-home pay is a layered calculation, and these tools keep the layers honest: federal brackets and the standard deduction first, then Social Security and Medicare on the full wage, then whatever your state adds, from nothing at all in nine states to a double-digit top rate in California. Federal figures follow the IRS inflation adjustments and SSA wage base for the current tax year and are reconciled against official worked examples before going live. The cost-of-living pages sit alongside, built on Bureau of Economic Analysis price data, so you can compare what a salary is actually worth between states before a move or an offer.
