# Net Revenue Churn (including expansion)
def net_revenue_churn(churned_revenue, expansion_revenue, starting_mrr):
    return ((churned_revenue - expansion_revenue) / starting_mrr) * 100

Lifetime Value (LTV)

Total revenue expected from a customer over their entire relationship.

# LTV calculation
def calculate_ltv(average_revenue_per_user, churn_rate):
    # LTV = ARPU / Churn Rate
    if churn_rate == 0:
        return float('inf')
    return average_revenue_per_user / (churn_rate / 100)

# Example
ltv = calculate_ltv(79, 5)  # $1,580 LTV

# LTV:CAC Ratio - should be at least 3:1
def ltv_cac_ratio(ltv, cac):
    return ltv / cac

ratio = ltv_cac_ratio(1580, 100)  # 15.8:1 - excellent!

Burn Rate

# Monthly burn rate
burn_rate = {
    "infrastructure": 200,    # AWS, hosting
    "software": 150,          # tools, subscriptions
    "marketing": 500,         # ads, content
    "total": 850              # Total monthly spend
}

# Runway = Cash / Burn Rate
def runway_months(cash, burn):
    return cash / burn

runway = runway_months(10000, 850)  # ~12 months runway

Revenue-Based Metrics for 2026
