Why this isn't trivial
The part people underestimate: the two price input and output very differently, so the savings depend entirely on your input:output ratio. In practice the biggest savings come from shifting quality-tolerant, high-volume traffic to the cheaper option, so it is worth modelling before you commit.
How it's calculated
We estimate this by applying both providers' rates to the same token sizes and volume and comparing totals. 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
How big is the gap?+
Often large on token price; the calculator quantifies it for your mix.
Should I move everything?+
Test quality first; move high-volume, low-risk traffic to capture most savings.
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.
