Mortgage companies play a crucial role in the housing market by providing individuals and businesses with the funds needed to purchase properties. But how do mortgage companies make money? In this article, we will explore the various ways mortgage companies generate revenue and sustain their operations.

Interest Income

Primary source of revenue: Mortgage companies primarily make money through interest income. When they lend money to borrowers, they charge an interest rate on the loan amount. This interest is paid by the borrower over the term of the mortgage, which can range from 15 to 30 years or more. The interest income generated from these loans forms a significant portion of a mortgage company’s revenue.

Loan Origination Fees

Additional source of revenue: Mortgage companies often charge borrowers loan origination fees. These fees are typically a percentage of the loan amount and are paid upfront by the borrower. Loan origination fees compensate the mortgage company for the costs associated with processing the loan application, conducting credit checks, and verifying the borrower’s financial information. These fees can vary depending on the mortgage company and the specific loan terms.

Servicing Fees

Recurring revenue stream: Mortgage companies can also generate revenue through servicing fees. After originating a loan, mortgage companies may choose to retain the servicing rights or sell them to other financial institutions. When they retain the servicing rights, they continue to collect payments from borrowers on behalf of the loan investors. In return for this service, mortgage companies earn servicing fees, which are typically a percentage of the outstanding loan balance. These fees provide a recurring revenue stream for mortgage companies.

Mortgage-Backed Securities

Profit from loan sales: Mortgage companies can package individual mortgages into mortgage-backed securities (MBS) and sell them to investors in the secondary market. By doing so, mortgage companies receive immediate funds from the sale of the MBS, allowing them to originate new loans. The profit generated from the sale of MBS can be a significant source of income for mortgage companies, especially when interest rates are favorable.

Secondary Market Gains

Opportunistic revenue: Mortgage companies can also generate revenue by taking advantage of fluctuations in interest rates. When interest rates decrease, mortgage companies can refinance existing mortgages at lower rates, allowing borrowers to save on interest payments. The mortgage company earns revenue through loan origination fees and interest income from the refinanced loans. Similarly, mortgage companies may also buy existing loans at a discount in the secondary market and earn income by collecting the full loan amount from borrowers.


In conclusion, mortgage companies make money through various avenues. Their primary source of revenue is the interest income generated from the loans they provide. Additionally, mortgage companies earn income from loan origination fees, servicing fees, the sale of mortgage-backed securities, and secondary market gains. These revenue streams allow mortgage companies to sustain their operations and continue providing individuals and businesses with the funds they need to purchase properties.
