About USA-Calc
USA-Calc is a free financial calculator platform built for people living and working in the United States. Every calculator uses real data — IRS tax brackets, BLS salary data, Freddie Mac mortgage rates — so the numbers you see reflect what you'd actually pay or earn, not estimates.
What We Cover
Our Data Sources
Tax calculations use official IRS publication data for federal income tax brackets, standard deductions, FICA rates, and capital gains thresholds. State income tax rates come from individual state revenue department publications. Salary data is sourced from the Bureau of Labor Statistics (BLS) Occupational Employment and Wage Statistics program. Mortgage rate assumptions reference Freddie Mac Primary Mortgage Market Survey data.
Accuracy & Disclaimer
USA-Calc calculations are for informational and educational purposes only. Results are estimates based on general tax rules and may not reflect your specific situation. Tax laws change, and individual circumstances vary. Always consult a qualified tax professional or financial advisor before making financial decisions.
