Knowing your team is underpaid and getting budget approval to fix it are two very different problems. This guide walks through how to build a salary adjustment proposal that finance and executive leadership will actually approve, grounded in market data rather than anecdote.
A data-backed business case is a structured proposal that quantifies the gap between current employee pay and market rates, estimates the financial risk of inaction, and presents a costed remediation plan. It translates compensation data into business language that finance teams and executives use to make budget decisions.
A strong business case answers these questions:
Most salary adjustment requests fail not because the need is unclear, but because the proposal does not speak the language of the audience. A request framed as "our people are underpaid and morale is low" gives leadership nothing to act on. A request framed as "12 employees in engineering have comp ratios below 0.85, representing $840,000 in annualized replacement risk, and the correction costs $54,000" changes the conversation entirely.
According to the Work Institute’s 2023 Retention Report, 75% of voluntary turnover is preventable, and compensation is consistently among the top three cited reasons for leaving. The business case connects those statistics to your specific workforce data.
Start with comp ratios for every employee. Comp Ratio = Current Salary ÷ Market Median. Use BLS wage data at the state level for the most accurate geographic benchmark. Flag every employee with a comp ratio below 0.90 as a candidate for adjustment and below 0.85 as high priority.
Segment the results by department and role. The goal is to show leadership exactly where the gaps are concentrated, not just that gaps exist. A business case that says "engineering has 8 employees below 0.85" is actionable. One that says "we have pay gaps" is not.
For every flagged employee, calculate the replacement cost. The standard range is 50% to 200% of annual salary, depending on role complexity and seniority. For a conservative estimate, use 100% (one times annual salary) as the multiplier.
If you have 12 employees at an average salary of $70,000 with comp ratios below 0.85, the estimated replacement cost if they leave is $840,000. That number belongs on the first page of your proposal. It reframes the conversation from "what will raises cost" to "what will inaction cost."
For each flagged employee, calculate the dollar amount needed to bring their salary to the target comp ratio (typically 0.95 to 1.00). Sum those amounts. This is your total remediation ask.
In most cases, the remediation number is surprisingly modest relative to the turnover risk. If correcting those 12 engineering employees requires an average increase of $4,500 each, the total ask is $54,000. Compare that to the $840,000 replacement risk. The ROI writes itself: a 15:1 return on retention investment.
Leadership rarely approves a full correction in one cycle. Build a phased plan that prioritizes by risk. The highest-priority employees are those with the lowest comp ratios in roles with the highest market demand and the longest time since last adjustment.
Present three tiers. Tier 1: comp ratio below 0.85 and no adjustment in 18+ months (immediate action). Tier 2: comp ratio 0.85 to 0.90 (next quarter). Tier 3: comp ratio 0.90 to 0.95 (annual review cycle). This gives leadership options and shows that you have thought through sequencing, not just the ask.
Structure the proposal as a one-page executive summary with supporting data tables. Lead with the risk number (total replacement cost), follow with the ask (remediation budget), and close with the ROI (cost avoided per dollar spent). Attach the detailed comp ratio analysis as an appendix.
Avoid HR jargon in the summary. "Comp ratio" can stay because it is quantitative and precise, but replace terms like "total rewards philosophy" with "pay strategy" and "talent attrition" with "employee turnover." The goal is to make the proposal readable by anyone on the executive team, not just the CHRO.
What It Pays™ uses government-verified BLS data as its foundation to calculate comp ratios across your entire workforce. The platform flags employees below your set threshold, segments results by department and role, and provides exportable reports that feed directly into business case documents. As the platform grows, it will layer in anonymized, real-time company salary data on top of the BLS foundation to strengthen your benchmarking evidence further.

What is a comp ratio and why does it matter for a business case?
Comp ratio is an employee’s current salary divided by the market median (or the organization’s target percentile). It quantifies how an employee’s pay compares to market. In a business case, comp ratios translate subjective feelings of underpayment into objective, defensible numbers that finance teams can evaluate.
What replacement cost multiplier should I use?
The standard range is 50% to 200% of annual salary. For a conservative business case, use 100% (1x salary). For senior or specialized roles, 150% to 200% is more realistic. Cite external research (SHRM, Work Institute) to support whichever multiplier you choose.
How do I prioritize which employees to adjust first?
Prioritize by the combination of lowest comp ratio, highest market demand for the role, and longest time since last salary adjustment. Employees who score highest on all three dimensions represent the greatest flight risk and should be addressed in the first phase of remediation.
What if leadership approves only part of the budget?
A tiered proposal anticipates this. If only Tier 1 is approved, you address the highest-risk employees immediately and return with updated data at the next cycle. Partial corrections still reduce overall risk and demonstrate that the process is disciplined and data-driven.
How often should I present a business case for salary adjustments?
Annually at minimum, timed to the budget planning cycle. If your organization has a mid-year review process, present an updated snapshot at that point as well. Quarterly comp ratio monitoring ensures you always have current data ready when the window opens.
Does What It Pays™ generate reports I can use in a business case?
Yes. Employers on the Essential plan and above can export comp ratio data, department-level summaries, and retention risk flags. These exports are designed to support exactly the kind of analysis described in this guide.
