How to Use This Calculator

Enter Modernization Cost and the Current Annual Energy Cost.
Set Energy Savings % achievable with new drive and lighting technology.
Input Current Maintenance Cost and expected Maintenance Savings % post-modernization.
Enter Current Callback Cost and Callback Reduction % from improved reliability.
Review Payback Period (years), Annual Net Savings, and 10-Year ROI to justify the project.

How the result changes with Modernization cost ($)

Modernization cost ($): Total cost of the elevator modernization project.
Current energy cost ($/yr): Current annual electricity cost for the elevator(s).
Energy savings (%): Expected energy reduction from new VVVF drives (typically 25-45%).
Current maintenance ($/yr): Current annual maintenance contract cost.
Maintenance savings (%): Expected maintenance cost reduction (typically 15-35%).
Current callback cost ($/yr): Annual cost of emergency service calls and entrapments.
Callback reduction (%): Expected reduction in emergency callbacks.
Property value lift (%): Estimated increase in property value from modernization.
Analysis period (years): Number of years to evaluate ROI.

Simple payback (years): Years to recover modernization cost from annual savings.
Total annual savings ($): Combined yearly savings from energy, maintenance, and callbacks.
Net benefit ($): Total savings minus modernization cost over the analysis period.
ROI (%): Return on investment over the analysis period.
NPV at 5% ($): Net present value of savings at 5% discount rate.
IRR (%): Internal rate of return on the modernization investment.
Energy savings ($/yr): Annual savings from reduced energy consumption.
Maintenance savings ($/yr): Annual savings from reduced maintenance costs.

Identify Input Parameters
4 parameters
Modernization cost ($) = 150000, Current energy cost ($/yr) = 15000, Energy savings (%) = 35, Current maintenance ($/yr) = 12000 = 9 input(s) provided
Calculate Simple payback
14 = 14
Calculate Total annual savings
Total annual savings = annualEnergySavings + annualMaintenanceSavings + annualCallbackSavings
10750 = $10,750
Calculate Net benefit
Net benefit = totalSavings + propertyValueGain - modernizationCost
26250 = $26,250
