How much would that be vs How much will that be


This may be a silly question but…

Is there a difference in meanings when you say “How much would that be ?”
and “How much will that be ?”

and when you reply
“That would be xx dollars/pounds”
“That will be xx dollars/pounds”

Thanks in advance

No significant difference in this context. ‘Would’ is often considered to be a ‘politer’ version.

Dear Beeesneees

No significant difference but a little politer. I got it. Thank you always !
