Personnel & Sales Expense: Why Loan Officer Compensation Dominates Origination Cost
Sales expense, primarily loan officer compensation and commission structures, is the single largest cost driver in mortgage origination. It accounted for 60% of total production cost at independent mortgage companies in 2025, according to MBA's Peer Group Roundtable data. Understanding why this line item stays dominant, even when volume drops, is the starting point for knowing where cost control actually has room to work.
What Counts as "Sales Expense" in Mortgage Production?
Sales expense covers more than a loan officer's base pay. It includes commission and override structures, sales management compensation, and often marketing or lead-generation spend tied directly to origination staff. Add standard benefits load on top of base and commission, health insurance, payroll taxes, retirement contributions, and the full sales expense line grows well beyond what a compensation plan alone suggests.
Why Doesn't Sales Expense Shrink When Volume Slows?
Commission scales with production, so in theory this cost should fall cleanly when volume drops. In practice, it doesn't, for a few consistent reasons. Base pay and draw structures for producing loan officers typically continue regardless of a slow month. Lenders are also reluctant to cut experienced sales staff during a downturn, since rebuilding a producing loan officer's pipeline and referral network after a departure takes far longer than the slow period that prompted the cut in the first place. That reluctance is well-founded: replacing any skilled employee carries real recruiting and ramp-up costs that often exceed the short-term savings from a layoff.

How Does This Compare Across Lender Types?
The 60% figure applies specifically to independent mortgage companies. Depositories run differently: sales expense accounts for a smaller 42% of their total origination cost, while corporate and production support, the back-office, compliance, and technology bucket, runs higher in proportion at 38%. This split reflects structural differences between the two lender types: depositories typically carry more centralized back-office and compliance infrastructure relative to their origination volume, while independent mortgage companies tend to run leaner support functions relative to a sales-heavy cost structure.
What Actually Drives Variation in Sales Expense Between Lenders?
A few factors explain why sales expense as a share of total cost varies from one lender to another: commission tier structures, average loan officer productivity, or volume produced per originator, and how much marketing and lead-generation spend gets allocated directly to sales rather than treated as a separate overhead line. A lender with highly productive loan officers generally sees a more efficient sales expense ratio than one carrying a larger sales force producing lower average volume per person.
Can This Cost Be Reduced Without Cutting Compensation?
Not easily, and that's an important distinction. Sales expense is tied directly to the people generating revenue, which makes it a much harder lever to pull than other cost categories without risking production itself. This is exactly why the more realistic opportunity for cost control usually sits on the other side of the ledger, in corporate and production support, where staffing structure and process design can be restructured without touching the compensation that drives origination volume in the first place.

Why This Matters When Comparing In-House vs. Outsourced Staffing
The same personnel-cost dynamics that make sales expense hard to reduce also apply, in a different form, to back-office staffing decisions. A salary figure alone understates the real cost of an in-house hire once benefits, turnover risk, and ramp-up time are factored in, the same categories that make sales expense stickier than commission percentages alone would suggest.

Frequently Asked Questions
What percentage of mortgage origination cost is loan officer compensation? Sales expense, primarily loan officer compensation, accounted for 60% of total origination cost at independent mortgage companies in 2025, according to MBA's Peer Group Roundtable data. Depositories ran lower at 42%, with a larger share allocated to corporate and production support instead.
Why does sales expense stay high even when loan volume drops? Base pay and draw structures for producing loan officers typically continue regardless of a slow month, and lenders are generally reluctant to cut experienced sales staff during downturns given how costly and slow it is to rebuild a producing loan officer's pipeline after a departure.
Should lenders try to reduce sales expense to lower overall origination cost? Generally not as a first move. Sales expense is tied directly to revenue generation, making it a riskier lever to pull than restructuring the corporate and production support side of the cost structure, where staffing efficiency can often be improved without affecting origination volume.
