Formula
const enteredInitialInvestment = Math.max(0, Number(inputs.initialInvestment || 0)); const enteredAnnualRevenue = Math.max(0, Number(inputs.annualRevenue || 0)); const enteredOperatingCosts = Math.max(0, Number(inputs.operatingCosts || 0)); const enteredProjectLifetime = Math.max(0, Number(inputs.projectLifetime || 0)); const lifetimeNetOperatingCashFlow = (enteredAnnualRevenue - enteredOperatingCosts) * enteredProjectLifetime; const lifetimeNetGain = lifetimeNetOperatingCashFlow - enteredInitialInvestment; const simpleLifetimeRoi = enteredInitialInvestment > 0 ? lifetimeNetGain / enteredInitialInvestment * 100 : 0; return { roi: Math.round(simpleLifetimeRoi * 100) / 100 };Initial Investment ($)
100,000
Annual Revenue ($)
20,000
Annual Operating Costs ($)
5,000
Project Lifetime (years)
20
Use the result to compare providers, request quotes, or send the scenario to a specialist when the numbers matter.
With the default inputs, annual net operating cash flow is $15,000. Over 20 years that totals $300,000; after subtracting the $100,000 initial investment, the $200,000 net gain equals a simple lifetime ROI of 200%.
Use this energy calculator to compare scenarios before committing money, time, or a provider conversation.
The estimate combines Initial Investment ($), Annual Revenue ($), Annual Operating Costs ($) and returns Simple Lifetime ROI.
If the result changes your decision, verify the current quote, rate, eligibility rule, or provider term before acting.
