Tech Calculator FAQ

Can tech calculators recommend exact products?+

They provide planning estimates, not vendor-specific buying advice. Always compare current provider pricing and requirements.

Why do technical estimates need a buffer?+

Real workloads vary. Traffic spikes, model overhead, caching, backups, and compression can all change final requirements.
