Formula

lpgMonthlyCost = (lpgCylinderPrice / lpgCylinderKg) * monthlyLpgKg; pipedMonthlyCost = pipedRatePerM3 * pipedMonthlyM3; monthlySaving = lpgMonthlyCost - pipedMonthlyCost

How the calculation works

A cylinder has a fixed price and a fixed weight, so the true per-kilogram cost only appears after dividing the price by the gas it contains.

Piped gas is metered by cubic metre, so its monthly cost is simply the rate multiplied by the volume the household burns.

Subtracting one monthly cost from the other shows the saving, which is the figure that justifies the connection charge and the pipe work.

Common mistakes

When to use it

Worked example

A 1450 taka cylinder of 12 kg used at 15 kg a month costs 1812.5 taka, while piped gas at 12.6 taka per cubic metre for 22 cubic metres costs 277.2, a saving of 1535.3 taka.

LPG monthly cost 1,812.50
Piped gas monthly cost 277.20
Monthly saving ৳1,535.30

Common questions

Why convert the cylinder to a per-kilogram rate?

A cylinder is sold at a fixed price for a fixed weight, so only the per-kilogram rate can be compared fairly with a piped bill charged by volume.
