MTBF Calculator

Use this calculator to find out the MTBF (mean time between failures) for a system with N identical components.

Serial reliability

(the system fails when any of the parts fail)

(the systems fails only when all N parts fail)

Not yet available.

There is hardly anything in the world that some man cannot make a little worse and sell a little cheaper.
