Job Leveling & Grade Midpoint Calculator

Calculate salary grade midpoints, range spreads, and compa-ratios to support structured compensation planning and job leveling decisions.

Grade Range Minimum ($)

Grade Range Maximum ($)

Employee Current Salary ($) (optional)

Number of Grade Steps (for progression)

Grade-to-Grade Progression (%)

Percentage increase from one grade midpoint to the next

#### Formulas Used

Grade Midpoint: Midpoint = (Range Minimum + Range Maximum) / 2

Range Spread: Range Spread (%) = ((Maximum − Minimum) / Minimum) × 100

Grade Progression (successive midpoints): Grade N Midpoint = Base Midpoint × (1 + Progression%)^(N−1)

Compa-Ratio: Compa-Ratio (%) = (Employee Salary / Grade Midpoint) × 100 100% = fully at midpoint; <80% = below competitive; >120% = above range

Position in Range (Range Penetration): Position (%) = ((Employee Salary − Minimum) / (Maximum − Minimum)) × 100 0–33%: Lower third | 34–66%: Middle third | 67–100%: Upper third

Successive Grade Min/Max (maintaining same spread): Grade N Min = Grade N Midpoint / (1 + Range Spread / 200) Grade N Max = Grade N Midpoint × (1 + Range Spread / 200)
