Factor comparison was developed in the 1920s and has sat quietly on the HR bookshelf ever since. Most companies default to market pricing or simple point factor systems, yet factor comparison still shows up when internal equity claims land or when a compensation committee wants a defensible paper trail tied to job content rather than market surveys. The method is slower than alternatives, but the output is unusually transparent. Every dollar of pay traces back to a specific compensable factor, which makes it hard to argue against and easy to explain to an employee who asks why their role sits where it does on the scale.
How the Method Actually Works Pick five to ten benchmark jobs that span the organization. For each benchmark, break the wage down into shares tied to the compensable factors: skill, mental effort, physical effort, responsibility, and working conditions. The result is a matrix that shows how much of each benchmark wage comes from each factor.
To price a new job, score it on the same factors, then sum the factor-level dollar values. A role that matches the benchmark on skill but requires more responsibility ends up priced slightly higher, traceable to that specific factor.
Where Factor Comparison Beats Other Methods It beats simple ranking when the organization has enough jobs to need real differentiation. It beats pure point factor when the pay structure needs to hold up in a legal challenge, because the method explicitly ties pay to job content rather than to points that require translation later.
When Should You Choose Factor Comparison Over Market Pricing? Use factor comparison when internal equity matters more than external market match, when market data is thin or unreliable for your job family, or when the company is rebuilding its job architecture from scratch. For pure market-following pay strategies, market pricing is faster.
The Trade-Offs Worth Knowing Factor comparison is resource-intensive. Developing the initial benchmark matrix takes weeks of work from comp specialists and job evaluators. Maintaining it takes ongoing effort as roles shift.
The factors themselves carry judgment. Reasonable comp analysts can weight skill versus responsibility differently and end up with different pay outcomes for the same job. Document the weighting decisions so the rationale survives staff turnover.
Running Factor Comparison as Part of a Modern Compensation Strategy Most mature HR teams don't run factor comparison in isolation. They use it to set internal structure, then calibrate against market data using the BLS Occupational Employment and Wage Statistics and commercial salary surveys. That combination produces a structure that defends internal equity while staying competitive externally.
Pair the evaluation output with clear compensation bands and a defined review cadence. Use the job evaluation work to inform performance review calibrations and promotion criteria, not just starting pay. When factor comparison is tied back to these operational decisions, the method earns its cost. When it sits in a binder, it doesn't. Audit classification against the compensable factor definitions annually to catch drift before it becomes inequity.
