Does it sound natural?
How much do you reckon it's going to be cost? (Can I use be cost instead of cost?)

Question

Answer

In this instance you would only need to use 'cost'. 'Be cost' is not grammatically correct. So the correct sentence would be:

"How much do you reckon it will cost?"

Or you could also say:

"How much do you reckon it will be?"

This sentence is also correct and could be used in the same context but this one does not need the word cost because it is already implied that you are asking about the price of something.

If you would like more help on grammar items please feel free to schedule a lesson with me.

Answer

Absolutely not. However you can say How much do you reckon it's going to be worth. That's because cost is a verb and worth is a noun.

Answer

No. Having 'be' in that sentence is incorrect. You need to remove it.
