ROI basic official
ROI = (profit / totalinvestmentcost) × 100
profit = total revenue - total cost
totalinvestmentcost = initial investment + operations cost

TCO comparison template
| cost item | current(AS-IS) | proposal(TO-BE) | gap |
|---|---|---|---|
| initial investment | ₩0 | ₩500M | +₩500M |
| annualbetween operations | ₩300M | ₩100M | -₩200M |
| 3year TCO | ₩900M | ₩800M | -₩100M |
| 5year TCO | ₩1500M | ₩1000M | -₩500M |
Payback Period (investmentnumberduration)
investmentnumberduration = initial investment / annualbetween currentflow
examplewhen:
initial investment: ₩500M
annualbetween reduction: ₩200M
Payback = 5 / 2 = 2.5year
NPV (currentvalue)
NPV = Σ [CF_t / (1+r)^t] - initialinvestment
CF_t = tyear also currentflow
r = to doperson (report WACC or goalrevenuerate)
t = annualgap (1~N)
judgment standard:
NPV > 0 → investment value
NPV < 0 → investment basiseach

IRR (withindepartmentrevenuerate)
IRR = NPV = 0 to doperson
judgment standard:
IRR > WACC → investment value
IRR > goalrevenuerate → investment capabilityquality
