## person·deployment cost comparison

### free utilization 

```
$0/month :
 : Vercel Free (100GB versus)
 DB: Supabase Free (500MB)
 authentication: Supabase Auth (50K MAU)
 storydegree: Supabase Storage (1GB)
 person: fromperson (*.vercel.app)
 email: Resend Free (100/day)

quality: MVP verify, initial user 100people or less
```

### cost ($10-30/month)

```
: Vercel Pro ($20/month) or Railway ($5~)
DB: Supabase Pro ($25/month) or PlanetScale Scaler ($29/month)
person: annual $12-15
email: Resend ($20/month)
monitoring: Sentry Free

total: $25-50/month (approx. 3-70,000 KRW)
quality: user 100-1,000people
```

### ROI total

```
minutebasispoint = month operations / (ARPU × beforeexchange × MAU)

examplewhen:
 month operations: 50,000 KRW
 : 9,900KRW/month
 beforeexchange: 3%
 needed MAU: 5 only / (9,900 × 0.03) = 168people

168people nature user needed
```
