1. What is the Monthly Gas And Electric Calculator?

The Monthly Gas And Electric Calculator estimates energy costs by calculating the combined expense of gas and electricity usage over a specified period, prorated to a monthly basis.

2. How Does the Calculator Work?

The calculator uses the cost formula:

\[ Cost = (Gas\ kWh \times Gas\ Rate + Electric\ kWh \times Electric\ Rate) \times \frac{Days}{30} \]

Where:

$ Gas\ kWh $ — Gas consumption in kilowatt-hours
$ Gas\ Rate $ — Gas rate in dollars per kWh
$ Electric\ kWh $ — Electricity consumption in kilowatt-hours
$ Electric\ Rate $ — Electricity rate in dollars per kWh
$ Days $ — Number of days in the billing period

Explanation: The equation calculates the total energy cost by summing the gas and electricity costs, then prorates it to a monthly basis using a 30-day month as reference.

3. Importance of Energy Cost Calculation

Details: Accurate energy cost estimation helps in budgeting, comparing energy providers, identifying consumption patterns, and making informed decisions about energy efficiency improvements.

4. Using the Calculator

Tips: Enter gas and electricity consumption in kWh, their respective rates in $/kWh, and the number of days in the billing period. All values must be valid (non-negative numbers, days between 1-31).

5. Frequently Asked Questions (FAQ)

Q1: Why use a 30-day month for proration?
A: Using 30 days provides a standardized monthly reference that works well for most billing cycles and simplifies monthly budget planning.

Q2: What if my billing cycle isn't exactly 30 days?
A: Enter the actual number of days in your billing period. The calculator will accurately prorate the cost based on your specific cycle length.

Q3: Can I use this for different energy units?
A: This calculator is designed for kWh units. If your bills use different units (therms, CCF), convert them to kWh first using appropriate conversion factors.

Q4: Does this include fixed fees and taxes?
A: No, this calculator only estimates the variable consumption costs. Fixed monthly fees, taxes, and other charges should be added separately to get the total bill amount.

Q5: How accurate is this estimation?
A: The accuracy depends on the precision of your input values. For tiered or time-of-use rates, more complex calculations may be needed.
