Overview

The Gas Bill Calculator estimates your monthly gas cost based on city gas (LNG) or LP gas usage. It accounts for usage type (cooking, heating, hot water), regional pricing, and seasonal rate variations.

Formula

Gas Bill = Base Charge + (Usage (㎥) × Heat Conversion Factor × Unit Price) + VAT (10%). City gas uses MJ (megajoule) as its heat unit, with rates varying by region and season.

How to Use

  1. 1Select the gas type (city gas / LPG).
  2. 2Select the usage purpose (cooking, heating, combined).
  3. 3Enter monthly usage in cubic meters (㎥).
  4. 4Select your region to apply local unit prices.
  5. 5The estimated gas bill is calculated automatically.

Tips

  • Lowering your boiler temperature by 1°C can save roughly 7% on heating costs.
  • City gas rates vary by regional gas company.
  • Winter heating gas usage can be 5–10 times that of summer.
  • Enter the exact usage from your meter reading for the most accurate estimate.
  • Improving floor insulation and sealing drafts can significantly reduce heating bills.

FAQ

Q. How do city gas and LP gas rates differ?

City gas (LNG) is delivered via pipeline and is relatively cheaper. LP gas (LPG) is delivered in tanks and has a higher unit price but is used in areas without pipeline infrastructure.

Q. How is the meter reading (㎥) converted to a bill?

Usage in ㎥ is multiplied by a heat conversion factor to obtain MJ, which is then multiplied by the per-MJ unit price to calculate the charge.

Q. What is the most effective way to reduce heating costs?

Maintain the boiler at a moderate temperature (18–20°C), improve insulation, and use scheduled heating when away from home.
