# Adjustment Method Formula (Text Version)

Note: This page contains historical data from CalRecycle’s statewide goal measurement prior to 2007 that estimated a diversion percentage. For 2007 and subsequent years, CalRecycle compares reported disposal tons to population to calculate per capita disposal expressed in pounds/person/day. This new goal measurement system is described in CalRecycle’s Goal Measurement: 2007 and Later web page.

## Calculations to Correct Base-Year Generation for Changes in Population and Economics, Disposal Tonnage, Goal Achievement, and Diversion

### Calculation to Correct Base-Year Generation for Changes in Population and Economics

1. Inflation Multiplier = Base-Year inflation / Reporting Year inflation
2. Report-Year Taxable Sales (inflation adjusted) = Inflation Multiplier x Reporting-Year Taxable Sales
3. Taxable Sales Multiplier = Reporting-Year Taxable Sales (Corrected) / Base-Year Taxable Sales
4. Employment Multiplier = Report-Year Employment / Base-Year Employment
5. Nonresidential Adjustment = (Employment Multiplier +Taxable Sales Multiplier) / 2
6. Population Multiplier = Reporting-Year Population / Base-Year Population
7. Residential Adjustment Factor = (Population Multiplier + Non-Residential Adjustment Factor) /2
8. Estimated Reporting-Year Generation Tonnage = [(Base-Year Residential Generation x Residential Adjustment Factor) + (Base-Year Nonresidential Generation x Non-Residential Adjustment Factor)]

### Computed Maximum Allowable Disposal Tonnage

1. Reporting-Year Maximum Allowable Disposal Percentage = 100 – Diversion Goal
2. Reporting-Year Maximum Allowable Disposal Tonnage = Estimated Reporting-Year Generation Tonnage x Reporting-Year Maximum Allowable Disposal Percentage

### Determination of Goal Achievement

1. Corrected Reporting-Year Disposal Tonnage = Reporting-Year Disposal Amount – Total Reporting-Year Correction Amount
2. Tonnage Over or Under Goal = Reporting-Year Maximum Allowable Disposal Tonnage – Corrected Reporting-Year Disposal Tonnage

### Calculated Diversion Rate

1. Reporting-Year Disposal Rate = Corrected Reporting-Year Disposal Tonnage / Estimated Reporting-Year Generation Tonnage
2. Reporting-Year Diversion Rate = 100 – Reporting-Year Disposal Rate
