Terms of Use

ToolsNode's calculators are free to use, no account needed.

Estimates, not advice. Results are estimates based on the formulas and sources shown on each page. They aren't financial, legal, or professional advice. Double-check anything that matters — a quote to a client, a tax filing, a production order.

Accuracy. We verify formulas and review dated figures on a schedule (see our methodology page), but rates and platform rules change. If something's stale, tell us at [email protected] and we'll fix it.

Acceptable use. Don't abuse the site — no scraping at aggressive rates, no attempting to disrupt the service.

Liability. We work hard to keep the math right, but we can't be liable for decisions made from these estimates. Use your judgment.
