Always free. Always available.

About this page

• Always free. Always available. We are committed to keeping MFG Calcs free, so useful manufacturing tools remain available to everyone who needs them.
• Used by thousands of professionals around the world, every month. Built in Massachusetts. Open to the world.
• Our mission: give every manufacturing professional access to useful calculations, clear explanations, and the data behind their decisions. Access to those tools should not depend on a software budget or the size of an employer.
• No account, subscription, or payment is required to use the platform. Free access is a responsibility we carry as we maintain existing tools, improve explanations, and make new capabilities available on the same terms.
• The tools show their methods, units, and assumptions so you can understand the answer and check whether it fits your situation. We review calculations, test changes, and welcome corrections through our contact page. Your judgment and the requirements of your work remain essential.
