Simple payback equals capital cost divided by annual savings; lifetime net savings equals annual savings times years minus capital cost.
FAQ
What does this calculator compute?
Simple payback is capital cost divided by annual savings. Lifetime net savings are annual savings times the number of years, minus capital cost.
What inputs does each project need?
Each item needs the capital cost and annual savings you supply, and the comparison uses the years you enter. The tool does not estimate savings from equipment data.
When should I not use the payback figure?
Do not use it as a financing, tax, or investment approval. It is the arithmetic of the costs and savings you typed.
