Industrial Gases & Cryogenic Systems calculator

Cylinder loss reserve Calculator

Use this calculator to estimate a cylinder loss reserve for an industrial gas fleet. It helps finance, branch managers, and asset teams compare missing, damaged, or written-off cylinders against the fleet at risk before setting reserve, deposit, rental, or recovery actions.

What this calculator does

  • Calculate cylinder loss reserve percentage from cylinders missing or written off, total cylinders at risk, and target loss reserve rate.
  • Use it when estimating reserve for lost cylinders, customer-held assets, unreturned cylinders, damaged cylinders, or write-offs.
  • The result shows cylinder losses as a percentage of the fleet at risk.

Formula used

  • Cylinder loss reserve rate = missing or written-off cylinders ÷ total cylinders at risk × 100
  • Cylinder loss reserve gap to target = cylinder loss reserve rate - target cylinder loss reserve rate

Inputs explained

  • Missing or written-off cylinders: Count cylinders lost, customer-held beyond policy, damaged beyond repair, scrapped, stolen, or written off.
  • Total cylinders at risk: Use the active fleet, customer-held fleet, rental fleet, or branch cylinder population exposed to loss.
  • Target cylinder loss reserve rate: Enter the finance, branch, customer, or asset management target for expected cylinder loss.

How to use the result

  • Use it to set reserve levels, prioritize recovery, adjust deposits, review rental policy, or plan cylinder purchases.
  • It depends on asset tracking accuracy, customer returns, write-off policy, cylinder transfers, scrap reporting, and the fleet population used.

Common questions

  • What is the cylinder loss reserve calculator for? It calculates the reserve rate for lost, missing, damaged, or written-off cylinders.
  • What information should I enter? Use missing or written-off cylinders, total cylinders at risk, and target reserve rate.
  • What does the result tell me? The result helps set reserve, deposit, rental, recovery, and cylinder purchase decisions.
  • When is the result only an estimate? It is only an estimate when tracking records, customer returns, scrap policy, or fleet population changes.
