Calculating return on investment (ROI) for lighting upgrades

Calculate ROI by dividing the net profit (savings from reduced energy consumption and maintenance costs minus the initial investment) by the initial investment, then multiply by 100 to get a percentage.

Consider energy consumption reduction, maintenance cost savings, lifespan of the new lighting, initial investment cost (including installation), and any potential rebates or incentives available in Singapore.

Compare the wattage of your old lights with the new ones, factor in the hours of daily use, and use your electricity bill to determine the cost per kilowatt-hour (kWh) in Singapore. Online energy calculators can also assist.

Check with the relevant Singaporean government agencies (e.g., the National Environment Agency) and utility providers (e.g., SP Group) for available grants, rebates, or incentives that can reduce the initial investment cost.

Improved lighting quality can enhance productivity, create a more pleasant ambiance, increase property value, and reduce eye strain, contributing to a better overall environment in your Singapore home or office.
