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.

If we deliver on time, but the product has defects, we have not delivered on time.
