# Reduce AI Token Cost Calculator > Real numbers from real users. How much you can actually save by self-hosting and caching. ## Quick Calculator | Your Monthly Spend | Local Models Only | Local + Caching | Total | |-------------------|------------------|-----------------|-------| | $50/month | Save $25-35 | Save $35-42 | $35-42 | | $100/month | Save $50-70 | Save $70-85 | $70-85 | | $200/month | Save $100-140 | Save $130-170 | $130-170 | | $500/month | Save $250-350 | Save $350-425 | $350-425 | | $1000/month | Save $500-700 | Save $700-850 | $700-850 | ## The Formula Simple formula to estimate your savings: ``` Savings = (Monthly Spend x 0.35) + (Monthly Spend x 0.35 x Cache Efficiency) ``` - **0.35**: Average savings from routing simple tasks to Ollama local models - **0.35**: Average percentage of queries that are repeated or similar - **Cache Efficiency**: How many cached queries actually match (typically 0.6-0.8) ## Real Examples - **Developer (individual)**: $150/mo API → save $90-110/mo with Ollama + caching - **Small team (3 people)**: $450/mo API → save $315-380/mo - **Agency (10 people)**: $1200/mo API → save $800-950/mo ## Setup Investment - **Time**: 2-4 hours to set up Ollama + caching - **Hardware**: $0 (use existing laptop) or $8/mo (VPS) - **Software**: Free and open-source ## Break-Even Analysis | Scenario | Setup Cost | Monthly Savings | Break-Even | |----------|-----------|----------------|------------| | Individual | $0 (use laptop) | $90 | Immediate | | Individual+VPS | $8/mo | $90-8 = $82 | Immediate | | Small team+VPS | $8/mo | $340 | Immediate | > The math is clear: even a single user saves enough in the first month to justify the 2-hour setup.
