questions about Interest rate central, interest, business, ask, discount

ShooterMcCFA

Hi, i have some questions on interest rates.

For central banks lending to depository institutes, central bank charge discount rate.

depository Institutes to depository institutes they charge federal rates

For people who deposit in the institutes, institute charge the market interest rate.

I like to ask, for business who are calculating the Cash flow of returns of incoming cash flows periodically, what is the rate they use? is it the market interest rates, discount rate or the federal fund rate?

And i just study about bonds, i understand that bond price falls when the market interest rate is higher than the coupon rate. Is the market interest rate the same as the rate institutes give to people whe they deposit in their institutes?


Thanks
