Cost of funds is the amount a lender pays to obtain the capital it lends out. It is shaped by interest expense, fees, and the lender’s funding sources. A lower cost of funds usually gives a lender more room to offer competitive pricing, while a higher cost tends to flow through to borrowers.
What Cost of Funds Means in Lending
Cost of funds is the lender’s own funding expense, not the borrower’s interest rate. It reflects what it costs to source capital from deposits, wholesale markets, securitisation, debt issuance, or other funding channels, and it helps determine how much margin remains after interest expense and fees are paid.
Why Cost of Funds Matters for Pricing
A lender with a lower cost of funds can usually price loans more competitively while still preserving spread. When funding becomes more expensive, the increase often works through to loan pricing, deposit pricing, fees, or tighter credit appetite, so the metric is central to margin management and product design.
What Drives Cost of Funds
The main drivers are the mix of funding sources, prevailing market rates, term structure, liquidity needs, credit quality, and the fees attached to raising capital. Deposit-heavy institutions may benefit from stable retail funding, while more market-dependent lenders can see cost move quickly with rate changes, spread widening, or reduced investor demand.
How Lenders Use It Operationally
Cost of funds is tracked as part of treasury, asset-liability management, and profitability analysis. It is used to evaluate whether a product is sustainably priced, whether a funding strategy is becoming too concentrated, and whether changes in rates or funding mix are eroding net interest margin over time.
