About PayCalc

Our Mission

PayCalc was created to provide everyone with free, accurate financial calculators that help make informed decisions about taxes, mortgages, investments, and loans. We believe financial tools should be accessible to all — no sign-ups, no tracking, no hidden fees.

Why Trust PayCalc?

Official Data Sources

Every calculation on PayCalc is powered by data from authoritative government and industry sources:

  • Federal Tax Brackets: Sourced directly from the IRS Revenue Procedure annual publications. We use the officially published 2026 tax brackets with standard deductions and FICA rates.
  • State Tax Brackets: Compiled from each state's official revenue department publications for all 50 US states plus Washington DC and Puerto Rico.
  • Mortgage Rates: Based on the Freddie Mac Primary Mortgage Market Survey (PMMS) — the same data used by industry professionals.
  • Tax Withholding Tables: Cross-referenced with IRS Publication 15-T for accurate payroll tax calculations.

Regular Updates

Our tax data is updated annually when the IRS releases new revenue procedures, typically in late fall for the following tax year. State tax rates are reviewed quarterly and updated whenever official changes are enacted. Mortgage rates are reviewed monthly against the latest Freddie Mac PMMS data.

Transparent Methodology

All formulas are based on standard US financial conventions:

  • Federal income tax uses marginal bracket calculations with 2026 standard deductions
  • FICA includes Social Security (6.2% up to $176,100 wage base) and Medicare (1.45% all wages, plus 0.9% Additional Medicare for high earners)
  • Mortgage calculations use standard amortization formulas with monthly compounding
  • Compound interest supports daily, monthly, quarterly, semi-annual, and annual compounding
  • Loan amortization produces full payment schedules with principal, interest, and remaining balance per period

Our Approach

PayCalc is designed with a privacy-first philosophy:

  • No sign-ups or accounts required — just open and calculate
  • No tracking, cookies, or analytics — your data stays on your device
  • No personal information collected — all calculations happen locally in your browser
  • Free, always — no premium tiers, no paywalls, no hidden costs

Who We Are

PayCalc is built by a small team of financial professionals and software engineers dedicated to making financial literacy accessible. Our calculators are designed with input from tax professionals and tested against official IRS worksheets and amortization tables to ensure accuracy.
