Neutrals

Even though you need to handle tie or provide multi pole breaker when using MWBC I would still think it would be cheaper than a job where you had to install dedicated neutrals. IMO it would be a lot more copper depending on the magnitude of the work. Agree?

Yes. More wire. More conduit. More labor. More money.

MWBC's will save money even if you have to buy and install handle ties. It's funny because when the simultaneous disconnect rule went into effect engineers just banned MWBC'S and went with separate neutrals. Now with the cost of copper some may be rethinking that strategy.

And there is also a small amount of energy savings when you use a mutiwire branch circuit.
