RunTheNumbersAI is a collection of practical calculators and decision tools designed to help people understand the real cost of using AI tools and software — before they commit to a plan, subscription, or workflow.
Many AI products look simple on the surface (for example, a flat monthly price vs pay-as-you-go). In reality, costs scale invisibly based on usage, message length, features, and behavior. Most people either overpay or underestimate what they’ll actually spend.
This site exists to prevent that.
What this site does
RunTheNumbersAI helps users:
- Compare flat-fee AI plans vs usage-based pricing
- Estimate real monthly costs based on actual behavior
- Identify break-even points and hidden cost thresholds
- Make clearer, lower-regret decisions before spending money
The tools focus on numbers first, explanations second — no hype, no “best tools” lists, no sales pressure.
How the calculators work
Our calculators use publicly available pricing, reasonable assumptions, and transparent logic to model real-world usage scenarios. They are designed to be:
- Simple to use
- Honest about trade-offs
- Clear about assumptions and limitations
Results are estimates, not guarantees. Actual costs may vary depending on provider changes, usage patterns, or additional fees.
Affiliate disclosure
Some pages may include references or links to third-party tools or services that users commonly consider after seeing their cost breakdowns. In some cases, we may earn a commission if a user chooses to sign up through those links — at no additional cost to the user.
Affiliate relationships never affect calculator logic, outcomes, or recommendations. Tools are suggested only when they logically follow from the numbers shown.
Our goal
The goal of RunTheNumbersAI is simple:
“Help people stop guessing what software and AI actually cost — and make decisions they won’t regret later.”
No fluff. No brand worship. Just clarity.
