SaaS tools advertise one price and charge another. We manually research every hidden fee, overage rule, and forced upgrade — so you know the true cost before you sign up.

Not AI-generated guesses. Our team reads pricing pages, terms of service, Reddit threads, support docs, and GetApp reviews for each tool. We document every overage rule, forced upgrade trigger, and surprise charge.
Tasks per month, team size, storage needs, premium apps — the numbers that actually drive your bill. Not the default 'starter' usage the pricing page assumes.
Line-by-line breakdown: base price, per-seat costs, overage charges, hidden fees. Plus a confidence score showing how reliable our estimate is. And cheaper alternatives with savings %.
Our 5-layer accuracy system starts at 85% with manual research. User-submitted bills push it to 90%+. Machine learning and API integrations eventually reach 98%. Every bill makes the calculator better for everyone.
