Two real costs, not just "free": the AI agent's own usage, and hosting once it's running. Both are estimated from this app's own effort rating and component list — see the assumptions on the method page.
| AI agent — with a subscription (Claude Pro/Max, Cursor, etc.) | $0 marginal |
| AI agent — pay-per-use API, no subscription | $43–$86 one-time |
| Hosting, once it's running | $10–$20/mo |
| Domain name, if you want your own | ~$12/yr |
Monarch Money costs $14.99/mo, but hosting alone could run $10–$20/mo — that can eat the whole subscription saving before the agent cost even comes into it.
