What does AI really cost in practice?
The AI Cost Calculator estimates what an AI solution actually costs you — one-time for setup and rollout, plus recurring per month for operation, licenses and maintenance. For SME owners who need a realistic budget before requesting a quote. No hidden items: the tool surfaces the typical cost blocks.
How it works
- 1Choose the type and scope of the AI solution you have in mind.
- 2Enter rough parameters — such as number of users, data volume or complexity.
- 3The calculator breaks down one-time and monthly costs, itemized by line.
Frequently asked questions
- Are these fixed prices from OsAI?
- No, they are guide figures based on common market ranges. Your actual quote can land below or above, depending on the detail. The calculator is meant to give you a sense of the ballpark, not a binding offer.
- Which costs are included?
- One-time items like concept, setup and training, plus recurring ones like software licenses, API usage, hosting and maintenance. Running costs in particular are often underestimated — that's why they're listed explicitly here.
- Do I need an account?
- No. The tool is free and usable without signing up. It runs in your browser and does not store your inputs on our servers.
- What do I do with the result?
- Take the estimated costs and feed them into the AI ROI Calculator — then you'll see whether the investment pays off. Or look straight at our packages to check whether a fixed scope fits.
