Description
share = bill/incomeBase.
Energy price comparisons require consistent delivered or input energy units, efficiency, calorific basis and reporting period. Dividing by efficiency increases the input needed for a delivered unit; nominal price differences alone need not represent a saving.
share = bill/incomeBase.
When to use this tool
Use Energy Poverty Bill Income Share Term when checking one supplied energy-price normalization or cost contribution.
How to use the tool and how it works
- Enter bill, income, housingCost, afterHousing. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read incomeBase, share. Use the output convention below.
Require nonnegative bill and housingCost and positive incomeBase = income-housingCost when afterHousing is true, otherwise income. share = bill/incomeBase.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| bill | Bill | Required. Finite number; minimum 0. |
| income | Income | Required. Finite number. |
| housingCost | Housing Cost | Required. Finite number; minimum 0. |
| afterHousing | Whether housingCost is deducted from income before calculating the bill share. | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| incomeBase | Income Base | Required. Finite number. |
| share | Dimensionless selected contribution divided by the stated total; not percent. | Required. Finite number. |

}Limitations and assumptions
- All monetary amounts cover the same period. A share above one is allowed; no energy-poverty classification, needs adjustment or eligibility threshold is selected.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use the full tariff, operating profile and cost boundary when assessing real bills, investments or load-shifting decisions.
