Typically, floating rate loans will cost less than fixed rate loans, depending in part on the yield curve. In return for paying a lower loan rate, the borrower takes the interest rate risk: the risk that rates will go up in future. In cases where the yield curve is inverted, the cost of borrowing at floating rates may actually be higher; in most cases, however, lenders require higher rates for longer-term fixed-rate loans, because they are bearing the interest rate risk (risking that the rate will go up, and they will get lower interest income than they would otherwise have had).
