The Energy Inflation Calculator helps you understand how much the price of energy has gone up over time. Whether you're tracking the rising cost of electricity, gas, or oil, this tool gives you a clear percentage showing how prices have changed. It is useful for comparing past and present prices and planning future budgets or business strategies.
This calculator belongs to the Energy Price Analysis and Financial Planning category. It is especially helpful for households, energy analysts, and utility planners who want to keep track of energy-related expenses.
Formula of Energy Inflation Calculator
Energy Inflation (%) = [(Current Energy Price − Past Energy Price) / Past Energy Price] × 100
Detailed Breakdown:
- Current Energy Price: The cost of the energy unit today (e.g., dollars per kilowatt-hour or dollars per gallon).
- Past Energy Price: The price of the same energy unit in the past.
- Energy Inflation (%): The percentage increase (or decrease) in the cost of energy over time.
This formula tells you how much energy prices have changed between two time points. A positive result means an increase, while a negative result shows a decrease.

Example of Energy Inflation Calculator
Let’s say the price of electricity was $0.15 per kWh last year, and today it’s $0.18 per kWh.
Apply the formula:
Energy Inflation (%) = [(0.18 − 0.15) / 0.15] × 100
Energy Inflation (%) = (0.03 / 0.15) × 100 = 20%
This means the cost of electricity increased by 20%.
