However, for specialized tasks (belt drives, rolling bearings, bolt groups), Mitcalc remains the most cost-effective professional suite—typically $150–$400 USD for a perpetual license. That is cheaper than one hour of a structural engineer’s billing time. Q: Can I use one Mitcalc authorization code on two computers (laptop + desktop)? A: Standard single-user licenses are for one computer at a time . Some vendors offer a "Home/Office" license allowing installation on two machines provided they are not used simultaneously. Check your EULA.
