How much runway will my AI costs consume?
Planning ahead? To see how AI costs consume startup runway, you need to see how today's per-user cost behaves as volume climbs. This page helps early-stage founders project the bill at scale before the growth (and the invoice) actually arrives.

Why this isn't trivial
The part people underestimate: AI spend that grows with usage can accelerate burn just as you're trying to extend runway. In practice the biggest savings come from capping AI spend as a share of burn until revenue covers it, so it is worth modelling before you commit.
How it's calculated
We estimate this by projecting AI spend against your monthly burn and cash balance. 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
Can AI cost threaten runway?+
If it grows unchecked with usage, yes — model it against burn explicitly.
How do I protect runway?+
Cap AI spend, use cheaper models pre-revenue, and scale cost with income.
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.
