Terms of Use
Last updated 15 November 2026. Use the tools freely; treat the results as estimates; the chronograph and your local regulations have the final word.
The service
Arrow Speed Calculator provides free archery ballistics calculators and reference tables, offered as-is for personal use. No account or payment is required, and no warranty — express or implied — attaches to the results.
Estimates, not measurements
Every result is an estimate computed from published standards and rules of thumb, as documented on the Methodology page. Real equipment varies. Nothing here replaces a chronograph, a manufacturer's own specifications or charts, or professional bow-shop advice — and for anything safety-relevant (minimum arrow or bolt weights, spine suitability, equipment condition), the manufacturer's instructions govern, always.
Safety and law
Archery equipment must be used in line with its maker's instructions and your local laws and hunting regulations, which override anything on this site where they differ. Guidance bands shown for game are commonly cited rules of thumb, not legal or ethical determinations for your hunt.
Content and liability
The site's text, tables and tool designs may not be republished wholesale. To the extent permitted by law, liability for any loss arising from use of these estimates is excluded; where a number here is wrong, the remedy offered is a prompt correction via the report an error page. These terms are governed by the laws of the United States.
