What is the cost of capital? When an organisation receives social investment, they will usually need to pay a return for using the money an investor lends them. Any social investor making loans expects to lend, and then be repaid. The aim is to cover the cost of lending and any default payments which means the money can be recycled and lent again. How much does social investment cost? Different investors will have different appetites for loss and return, and this will determine how much capital is available and what it will cost. The cost of capital is often simplified to the interest rate that you will be charged.
