Free tools, no email gate
FinOps calculators that do not waste your time.
We built these because the calculators that already exist either gate the results behind a sales call, or hardcode the discount rate from 2019, or both. Use whichever one applies. None of them ask for your email.

If a calculator does its job
It tells you the answer. Then it gets out of the way.
Once you know the number, the next question is whether your actual cloud bill matches the projection. Cloud Horizon runs a 14-day read-only audit and tells you what is actually happening in your account. Free, one-page CFO report.
