TAM/SAM/SOM framework
and calculation
TAM (Total Addressable Market): overall market scale
→ applicable problem overall re- client × annualbetween expense
SAM (Serviceable Addressable Market): possible market
→ TAM × degree//platform constraint
SOM (Serviceable Obtainable Market): actual possible market
→ SAM × realistic market point (1person companyproject: 0.1-1%)
Top-Down method
examplewhen: developmentspecialist interview preparation web
TAM: before taxtotal developmentspecialist 2,700people × annual $50 expense
= $13.500M
SAM: Korean user (Korean developmentspecialist approx. 50people) × $50
= $2,500
SOM: 1% market point possible (1person operations)
= $25 only (approx. 3.300M KRW/year)
Bottom-Up method
examplewhen: developmentspecialist interview preparation web
month beforeexchange expected:
blog/SNS → documentspecialist: month 10,000people
KRW beforeexchange: 10% = 1,000people
beforeexchange: 5% = 50people
month : 9,900KRW
MRR = 50 × 9,900 = 495,000KRW
ARR = 5940,000 KRW
nature scenario (12months after):
documentspecialist 3 → MRR 1500,000 KRW → ARR 1,8000,000 KRW
revenue model typeby total
model (SaaS)
core indicator:
MRR = user × month
ARR = MRR × 12
LTV = ARPU / rate
CAC = cost / specialist
casebeforenature standard:
LTV/CAC > 3
rate < 5%/month
number duration < 12months
examplewhen:
100people × 9,900KRW/month = MRR 990,000 KRW
month 5% → pyeongbalanced numberpeople 20months
LTV = 9,900 × 20 = 198,000KRW
CAC 30,000KRW → LTV/CAC = 6.6 ✅
premium model (Freemium)
free user → beforeexchange: 2-5% (general)
premium price: free versus feature differentiation
examplewhen:
free 10,000people → beforeexchange 3% = 300people
month 19,900KRW → MRR 5970,000 KRW
daynature
expected = × beforeexchange
examplewhen (degree ):
blog month document 10,000 × beforeexchange 1% = 100case
price 29,000KRW → month 2900,000 KRW
