| Ad Impressions | Total number of ads shown to users monthly. | 1B+ | Indicates platform reach and engagement. |
| Ad Revenue per User (ARPU) | Average revenue generated per user from ads. | $5–$20 annually | Higher ARPU reflects better ad targeting and inventory utilization. |

3. Unit Economics
Sample Inputs:
Monthly active users (MAU): 100M
Ad impressions per user: 100/month
Revenue per ad impression: $0.01
Infrastructure cost per user: $0.50/month
Customer acquisition cost (CAC): $5
Retention rate: 90%
Sample Outputs:
Monthly Revenue:
Formula:
MAU × Ad Impressions per User × Revenue per AdCalculation:
100,000,000 × 100 × $0.01 = $100,000,000
Annual Revenue:
Formula:
Monthly Revenue × 12Calculation:
$100,000,000 × 12 = $1,200,000,000
Gross Profit:
Formula:
Revenue - (Infrastructure Costs)Calculation:
$1,200,000,000 - ($0.50 × 100,000,000 × 12) = $600,000,000
CLTV:
Formula:
(ARPU × Retention Rate) ÷ (1 - Retention Rate)Calculation:
($12 × 0.90) ÷ (1 - 0.90) = $108
Payback Period:
Formula:
CAC ÷ ARPUCalculation:
$5 ÷ $12 = 0.42 months (~13 days)
