Frequently Asked Questions
Are these tools actually free?
Yes. No paywalls, no premium tier, no signup. The site is supported by display ads, not subscriptions.
Do you store what I type into the calculators?
No. Every calculation runs client-side in your browser; nothing you enter is sent to or stored on a server. See our Privacy Policy for details.
How accurate are the tax and financial calculators?
Tools that reference tax brackets, SE tax rates, or statutory caps are built against current-year IRS and SSA figures and reviewed periodically. They're simplified estimates meant to help you make a decision quickly — not tax, legal, or financial advice. For anything with real stakes, confirm with a CPA or attorney.
How often are the tools updated?
Tax-year constants are reviewed annually when new IRS/SSA figures are published, and tools are patched promptly when a bug is reported.
Can I suggest a new tool or report a bug?
Yes — email [email protected]. We read every message.
