ℹ️ About Us
Who we are, how we work, and what our data is based on — all here.
What We Do
GelirLab.com offers 114 free calculators for salary, taxes, loans, investments, freelance income, and everyday financial decisions, alongside a financial glossary. Our goal is to turn scattered, technical financial information into a form anyone can understand and calculate directly.
How We Keep Our Data Current
The data behind our calculators — such as federal tax brackets, FICA rates, 401(k) contribution limits, and IRS mileage rates — is regularly reviewed and updated. Each relevant tool states the source it relies on and when that data was last verified — we never present a figure without a source.
What Our Calculations Are Based On
Our tools are based on official sources — IRS publications, U.S. Department of Labor guidance, and other public references. Where a calculation isn't based on official regulation (for example, general budgeting tools like the 50/30/20 rule), we say so clearly and don't claim precision we don't have.
We're Honest About Our Limits
None of the tools on our site replace professional legal, tax, investment, or financial advice. For complex or high-stakes decisions, we recommend consulting a qualified professional (a CPA, attorney, or financial advisor) in the relevant field. Each tool's own page notes any limitations specific to that calculation.
Found an Error?
If you think a calculation has an error, you can reach us through our Contact page. Your feedback is the most valuable resource we have for keeping our data accurate.
