ARPU

ARPU (Average Revenue Per User) is a core metric that divides your total revenue by the number of active users in a given period, typically monthly. For a SaaS product with ₹10 lakh revenue and 500 active users, ARPU is ₹2,000/month. It reveals unit economics and pricing power.

ARPU alone is misleading. A ₹5,000/month ARPU means nothing if 60% of users churn quarterly. The true health metric is ARPU × retention. A ₹2,000 ARPU with 90% monthly retention is far healthier than ₹5,000 ARPU with 40% retention. Retention multiplies value; high ARPU with low retention is a leaky bucket.

Track ARPU by cohort, geography, and product tier. Indian B2B SaaS typically sees ₹500–₹5,000 ARPU depending on use case; B2C apps see ₹50–₹500. Compare ARPU trends month-on-month. A rising ARPU signals better monetization or premium customer mix. Declining ARPU often flags product-market fit issues or price compression.

ARPU is not revenue. It's a per-unit efficiency marker. Investors care about ARPU × retention × payback period together, not ARPU in isolation.

Indian startups often chase headline ARPU numbers without managing churn. PhonePe and Razorpay built sustainable models by pairing high ARPU with deep retention and frequency. Most Indian B2B SaaS targets ₹1,000–₹3,000 ARPU; B2C consumer apps aim for ₹100–₹300 and rely on scale. Tax compliance (GST, TDS) must be factored into net ARPU calculations—especially for fintech, where 18% GST reduces real ARPU by ≈15%.

RBI guidelines for payments businesses and insurance platforms require clear revenue segregation (transaction fees vs. services), which affects ARPU definition. Indian founders often conflate GMV (Gross Merchandise Value) with revenue; ARPU must use actual revenue only. Early-stage Indian startups (Series A–B) targeting global benchmarks often ignore India's lower willingness-to-pay; sustainable ARPU here is 30–40% of comparable US SaaS.

Regulatory ARPU floors exist in telecom (TRAI) and insurance (IRDAI), but most tech startups operate freely. Focus on ARPU profitability: if CAC (Customer Acquisition Cost) is ₹5,000 and payback is 8+ months, ARPU growth alone won't save unprofitable unit economics.
