About PayStubIQ

Last reviewed: July 13, 2026

PayStubIQ provides practical estimate calculators for U.S. paycheck planning. The site focuses on clear assumptions, consistent formulas, and quick results for workers comparing paycheck, hourly, salary, overtime, bonus, self-employed, quarterly, and 1099 scenarios.

What the calculators are built to do

The tools estimate common payroll outcomes from user-entered wages, pay frequency, filing status, state, pre-tax deductions, post-tax deductions, extra withholding, and optional local tax assumptions. The goal is to help visitors understand planning ranges before they compare the estimate with a real paystub or payroll portal.

State-aware pages use structured state tax configuration data and plain-language notes so visitors can see when a state has no wage income tax, flat-rate tax, or progressive brackets. Conversion pages keep gross hourly and salary math separate from after-tax estimates so the assumptions are clear.

How we keep results transparent

PayStubIQ separates federal income tax, FICA, state tax, local tax, pre-tax deductions, post-tax deductions, and net pay where the calculator supports those lines. Each calculator is intended for education and planning rather than payroll processing, filing, or professional tax advice.

Tax rules, payroll systems, and personal elections can change. We review formulas and site copy periodically, and we prioritize corrections when a visitor reports a calculation issue with enough detail to reproduce it.

Federal tax-year sources and the limits of the state planning model are documented on the methodology page.

Our sourcing, correction, testing, and disclosure practices are documented in editorial standards. PayStubIQ does not claim CPA, attorney, or payroll-provider review when that review has not occurred.
