 Output price (€ / 1M tokens)
 
 
 

 
 
 
 Estimated cost
 

 
 Total estimated cost
 € 0,423
 Exact: € 0.423000
 

 
 
 Input cost (100.000 tokens)
 € 0,2350
 
 
 Cached input cost (0 tokens)
 € 0,0000
 
 
 Output cost (20.000 tokens)
 € 0,1880
 
 

 
 
 Calculation formula & explanation
 Costs are computed from the entered rates per million tokens:

 Kosten = (InputTokens / 1M × PrijsInput) + (CachedTokens / 1M × PrijsCached) + (OutputTokens / 1M × PrijsOutput)
 Note: actual costs on your invoice can differ slightly through exchange rate fluctuations (USD to EUR) and rounding per API call.

 
 
 

 
 
 
 
### Background & theory

 Want to understand exactly how tokenization works, what context windows mean and how prompt caching can lower your input costs by as much as 90% on modern models (around 50% on older ones)?
