Discount for paying Cash to contractor?

Hi,
I am in the home stretch of kitchen/bath renovation. Contractor is doing excellent work. Not worried about him walking off the job and job is on schedule. All has been legit.
I have been paying installments by check. There are 3 installments left for a total of about $15,000. last installment is due upon the jobs completion. I asked the contractor if we payed each of the last 3 installments in cash if they’d give us a better price for those 3 and he said he’d let us know in a day or so. If he agrees what should I expect the discount to be for the remaining $15,000? I’m not sure what to expect and what is fair. Any suggestions?
Thank you.
