Designing and Managing Base Pay Systems
Designing and Managing Base Pay Systems tests the mechanics of job evaluation, pay structures, and movement through ranges - including the formulas exam writers use to separate compa-ratio from range penetration.
Build order
Job analysis produces job documentation; job evaluation (point-factor, ranking, classification, or market-based) establishes internal hierarchy; market pricing anchors the structure; grades and ranges translate that hierarchy into pay opportunities. A range has a minimum, midpoint, and maximum. Midpoint = (min + max) ÷ 2. Range spread = (max − min) ÷ min. Overlap between grades supports progression. A pay policy line plots market values against job evaluation points.
Managing movement
Compa-ratio = pay ÷ midpoint, showing positioning against the range midpoint. Range penetration = (pay − min) ÷ (max − min), showing position within the range. A merit matrix combines performance rating and compa-ratio to allocate increases. Red-circle pay above maximum is usually frozen until the range moves; green-circle pay below minimum is corrected through a plan, not a one-off. Step and scale structures suit predictable progression; open ranges suit broad roles. Employees should understand how their pay is determined and what moves it.
Worked example
Grade 5: minimum $60,000, maximum $90,000. Midpoint = $75,000; spread = ($90,000 − $60,000) ÷ $60,000 = 50%. Employee A earns $66,000: compa-ratio = 88%; range penetration = ($66,000 − $60,000) ÷ $30,000 = 20%. Employee B earns $94,000: red-circled at 125.3% compa-ratio. If the market median for the benchmark is $78,000, the midpoint lags the market by ($78,000 − $75,000) ÷ $78,000 = 3.8%. The analyst should first age the market data and confirm the job match before recommending a structure adjustment.
Traps that cost marks
- Using midpoint as if it were the market median.
- Confusing compa-ratio with range penetration.
- Setting ranges so narrow that employees hit the maximum within two years.
- Treating red-circle pay as a permanent entitlement with no review.
- Giving merit increases that push employees further above maximum.
