Toolkit FAQ

Do I have to sign up to use these?
No. Every calculator runs in your browser. We only ask for email and phone if you want the detailed PDF report mailed and texted to you. The on-screen numbers are free forever.
Where do the industry defaults come from?
We blend three sources: (1) public industry benchmark reports (OpenView, ChartMogul, Klaviyo, BrightLocal, Bessemer State of the Cloud), (2) Nirvani's own deployment data across 200+ live SMB clients, and (3) operator interviews. Defaults are medians, not means. You can override any field with the sliders or number inputs.
Is the SMS / phone capture A2P compliant?
Yes. Every form on this site collects explicit opt-in consent with required A2P 10DLC disclosures: msg frequency varies, msg/data rates may apply, reply STOP to opt out, HELP for help. Phone numbers are never shared with third parties for marketing. Full terms at SMS Privacy & Terms.
Can I share or embed these calculators?
Sharing is encouraged. Each calculator has a clean canonical URL you can drop into a blog post or newsletter. Embed support (iframe widget) is in progress. Ping the founder via the contact page if you want early access.
Why is the math so opinionated?
Because most SaaS calculators online are wrong on purpose. They use revenue instead of gross margin, ignore expansion, and assume zero churn. Real operator math doesn't work that way. Every formula in this toolkit is the same one we'd use to underwrite a deal.
Will more tools be added?
Yes. New calculators ship roughly every two weeks. Currently in the queue: lifetime margin by cohort, cash conversion cycle, SaaS rule of 40, embed widget builder, and a Maricopa-specific RE flip underwriting calculator. Subscribe to the founder email at the bottom of the page to get pinged.
