Leak Cost Calculator

This tool estimates what a compressed air leak costs to run each year, from figures you enter about your leak, your compressor and your electricity price. Everything runs in your browser: nothing is sent anywhere.

How do you know the leak rate?

Measured leak flow Leak flow, litres per minute (from a leak survey or drop test)

Compressor and tariff Compressor's free air delivery, litres per minute

Electrical input at full load, kW (from the data plate)

Hours a year the air system is pressurised

Your electricity price, pence per kWh

UK non-domestic electricity prices are published quarterly by the Department for Energy Security and Net Zero: see the published figures.

This assumes the compressor runs at full load in proportion to the air it delivers, which is an approximation for a load and unload or variable speed machine.
