Cost pages / Internal tool
How much does it cost to build an internal tool with AI?
About $38 to $102 in plan spend — the subscription money, not what the usage is notionally worth — depending on which builder you point at it. Bolt.new comes out cheapest at about $38, on usage worth $32 of tokens; v0 by Vercel is the expensive end at about $102. That is an internal tool with 2 standard features, built by someone who iterates two or three times per feature — the ×2.5 iteration tax and the +40% debug surcharge are already in these numbers.
Screens to add, edit and view your team's records. No public visitors. Priced as a simple build — that is how many screens and rules it has, not how good it is. Simple has fewer, complex has more.
These tools bill in their own units. Credits are prepaid units of work you get each month; tokens are the chunks of text the AI reads and writes; the rest bill in plain dollars.

✂ CHEAPEST PLAN SPEND: BOLT.NEW
Plan spend = the subscription money you hand over. Usage value = what the units you burn are worth at this tool’s own rate; nobody invoices you for it. Iteration tax = the extra rounds it takes to get each feature right. Debug surcharge = fixing what breaks.
Tokens are priced by how much work a request takes, and bug-fixing loops are the killer — people have burned 2M+ tokens in a day chasing one bug. Unused tokens roll over one month only, so they last two months at most. Prices verified 2026-08-10.

Internal tool cost by platform
Midpoint of each estimate, ranked by plan spend — the cash you actually hand over, on whichever published plan settles the build for least. Usage value is what the units you burn are worth at the platform’s own rate; it is the smaller number, and nobody invoices you for it. “How you pay” names the plan: plans with no overage bill whole months, while the rest bill one month plus whatever spills past the allowance.
