Every AI feature sounds like a money-saver in the pitch meeting. A chatbot will answer customers overnight, a writing tool will draft reports in seconds, and a smart search tool will end wasted time. Some of these ideas do pay for themselves. Many do not. The difference is rarely the technology. It is whether anyone ran the return-on-investment math before building.
Start with the cost side, and count everything, not just the obvious bill. First, add your API or token spend for a typical month, based on real usage, not the cheapest demo. Then add tool subscriptions, seats, and any extra data or hosting costs. Finally, and most importantly, add build and maintenance time. If a developer spends ten hours building a feature and two hours a month keeping it working, value that time at a realistic hourly rate. Free internal time is not free. When you leave it out, almost every feature looks profitable.
Next, work out the benefit side in the same monthly terms. How many hours will the feature really save each week, and for how many people? Multiply those hours by the same hourly rate you used for costs. Add tasks automated that would otherwise need hiring or overtime, and errors avoided, such as fewer refunds, rework, or support tickets. Be honest here. A tool that saves five minutes a day for one person is not the same as a tool that saves five hours a week for a whole team.
Now compare monthly cost with monthly value. If the feature costs $800 a month, including time, and saves $2,000 a month in useful work, it is a promising investment. If it costs $800 and saves $300, it is a cost centre, not an investment, however impressive the demo looked. Do not rely on one best-case guess. Run a low case, a typical case, and a high case for both usage and savings. If the feature only pays in the high case, it is a gamble, not a plan. If it pays even in the low case, you have a much stronger reason to build it.
Running these numbers by hand is a good start, but a simple calculator makes the comparison clearer and harder to fudge.

Before you approve the next feature, ask one plain question: will the monthly value clearly beat the monthly cost? If not, pause, simplify the idea, or drop it. Good AI spending starts with that discipline, not with the launch.
