Why this isn't trivial
The part people underestimate: Perplexity bundles search into a per-request fee, while GPT + RAG splits cost across retrieval, storage and generation. In practice the biggest savings come from using the bundled option for low volume and self-built RAG at scale, so it is worth modelling before you commit.
How it's calculated
We estimate this by comparing Perplexity's per-request search+token fee against the all-in per-query cost of GPT with your own RAG. Every figure uses the current provider prices baked into the site (reviewed daily), and you can override any input to match your own assumptions.
Frequently asked questions
When is a bundled search API cheaper?+
At low to moderate volume where building and maintaining RAG isn't worth it.
When does self-built RAG win?+
At high volume, where per-query cost beats bundled fees despite build effort.
Are these prices up to date?+
Yes. The model prices behind this calculator are refreshed and reviewed daily, so your estimate reflects current provider rates rather than a stale snapshot.
