Annual Heating Cost Formula
The calculator uses straightforward mathematical formulas to estimate heating expenses.
Monthly Heating Cost
Monthly Heating Cost = Monthly Energy Usage × Cost Per Unit
Example:
Monthly Usage = 900 kWh
Cost = $0.15 per kWh
Monthly Cost =
900 × 0.15
= $135
Annual Heating Cost
Annual Heating Cost = Monthly Heating Cost × Heating Months
Example:
$135 × 6
= $810
Annual Energy Consumption
Annual Energy Consumption = Monthly Usage × Heating Months
Example:
900 × 6
= 5,400 kWh
Efficiency-Adjusted Heating Cost
The calculator also estimates the impact of system efficiency using:
Adjusted Cost = Annual Heating Cost ÷ (Efficiency ÷ 100)
Example:
Annual Cost = $810
Efficiency = 90%
Adjusted Cost =
810 ÷ 0.90
= $900
This illustrates how lower system efficiency can increase the effective cost of delivering the required heat.
Example Calculation
Suppose your household has the following heating information:
| Input | Value |
|---|---|
| Monthly Energy Usage | 950 kWh |
| Energy Price | $0.17/kWh |
| Heating Months | 6 |
| System Efficiency | 92% |
Step 1: Monthly Heating Cost
950 × 0.17
= $161.50
Step 2: Annual Heating Cost
161.50 × 6
= $969.00
Step 3: Annual Energy Consumption
950 × 6
= 5,700 kWh
Step 4: Adjusted Cost
969 ÷ 0.92
= $1,053.26
Final Results
| Result | Value |
|---|---|
| Monthly Heating Cost | $161.50 |
| Annual Heating Cost | $969.00 |
| Annual Energy Consumption | 5,700 kWh |
| Adjusted Cost | $1,053.26 |
