The social discount rate is used to calculate the net present value (NPV) of a time stream of benefits and costs of a project where its NPV is calculated as NPV = Σ t (B t- C t /(1 + i) t ) B t is the expected gross benefit of the project at time t, C, is the expected gross cost of the project at time I, and i is the social discount rate at The discount rate is the interest rate the Federal Reserve charges on loans it makes to banks and other financial institutions. The discount rate becomes the base interest rate for most consumer borrowing as well.
