## RISK FACTORS & CONTINGENCIES

### High-Risk Cost Items:
1. **Video Calling** - Can spike unexpectedly
   - Mitigation: Set usage alerts, implement time limits
   
2. **Storage Growth** - User-generated content adds up
   - Mitigation: Aggressive lifecycle policies, compression

3. **Database** - After free tier expires
   - Mitigation: Optimize queries, implement caching

### Contingency Budget:
Always maintain **20-30% buffer** for unexpected spikes

---

## CONCLUSION

**OviEdu can launch with as little as ₹1,500-2,000/month** by maximizing free tiers and smart resource usage. 

As the platform grows to 10,000+ active users with significant video mentorship usage, expect costs to scale to **₹15,000-25,000/month**.

At maturity (50,000+ users), budget for **₹40,000-60,000/month**, which is still very competitive compared to similar platforms.

**Total First Year Projection: ₹60,000-1,20,000**  
**Total Second Year Projection: ₹2,40,000-4,80,000**
