Do vs Model Pay Overview
Do vs model pay refers to the difference in compensation between employees in "do" roles, such as engineers and analysts, and those in "model" roles, such as quantitative and financial modelers. In 2025, base salaries for do roles at large financial firms and tech companies often range from $100,000 to $200,000, while model roles can range from $120,000 to $250,000, with total compensation frequently exceeding base pay by 50 to 100 percent or more. According to recent compensation surveys and SEC filings, firms like Tesla and SpaceX pay senior do and model staff through salary, stock, and bonus structures that reflect the direct impact of their work on revenue and risk models Forbes quantitative analyst pay data.
The core distinction in do vs model pay is that do roles typically execute strategies, build products, or manage operations, while model roles design, test, and validate the assumptions and algorithms behind those strategies. In investment banks and hedge funds, a junior modeler might earn a base salary comparable to a junior do analyst, but total pay can diverge sharply at senior levels because modelers often receive larger bonuses tied to the performance of the models they own. Public filings from companies like Tesla show that compensation for technical and financial staff is heavily weighted toward long-term incentives, linking pay directly to model accuracy and business outcomes Tesla SEC proxy statement.
Salary Ranges and Compensation Structure
For do roles, entry-level salaries at major tech and finance firms in 2025 often start around $100,000 to $130,000, with total compensation reaching $200,000 or more after bonuses and equity. Model roles, especially in quantitative finance and data science, can start at similar base levels but offer higher bonus potential, with total compensation for experienced modelers at top firms exceeding $300,000 to $500,000. At SpaceX, compensation for technical and modeling staff includes base salary, performance bonuses, and stock awards, with senior roles offering packages that reflect the company's private valuation and long-term milestones Forbes SpaceX compensation breakdown.
Compensation structures for do vs model roles differ in how risk and reward are allocated. Do roles often receive more predictable base pay with bonuses tied to team or company performance, while model roles may have compensation heavily dependent on the accuracy and profitability of the models they build. In financial institutions, a modeler whose risk models directly influence trading revenue can earn significantly more than a do analyst performing similar-level tasks, especially when the models contribute to alpha generation or cost savings. SEC filings and pay disclosures show that firms increasingly use equity and deferred compensation to align modelers' incentives with long-term model performance and business growth SEC EDGAR filings.
Factors That Influence Pay Differences
Several factors drive differences in do vs model pay, including skill specialization, market demand, and the measurable impact of the role. Modelers with expertise in machine learning, statistical modeling, or quantitative finance often command higher pay because their work directly affects
