Lighting Maintenance Budget Calculator

Annual replacement volume, consumable cost, labour hours, and the relamping interval implied by rated life.

Inputs

The lighting

Luminaires covered by the maintenance budget.

Sets rated life. Use the real product life, not the catalogue headline figure.

Hours the lighting actually runs, including after-hours cleaning and security use.

Costs

Lamp, tube, module, or driver cost per replacement, plus any disposal fee.

Minutes per replacement including access, setup, and disposal. High ceilings cost more.

Fully loaded hourly cost of the person doing the work.

Spot replacement pays full labour every visit; planned group relamping amortises it.

What to check

  • Rated life for the actual drive current and ambient temperature, not the catalogue headline
  • Access cost per position for the real ceiling height
  • Consumable price including freight and disposal of the old lamp or module

This calculator is a first-pass screen. Rated life is a laboratory figure at a reference temperature; heat, vibration, and voltage quality shorten it in service, so track actual failures for a year before contracting a multi-year budget.
