Questions

Is RealCostIQ really free?+
Yes — all 220+ calculators are free to use, with no sign-up and no email. We never gate results behind a lead form.
How accurate are the estimates?+
Cost data is reviewed quarterly using labor and materials price indexes. Results are estimates and will vary by location, so always confirm with a licensed professional.
Do you store my data?+
Every calculation runs entirely in your browser, and the figures you type are never sent to us. We do record anonymous statistics — which calculator ran and the broad range each input and result fell into, such as “$350k–$500k” — with no identifier that lasts beyond the day. Nothing personal is collected.
Which countries are supported?+
The United States, Canada and India are live today, with local rates, rules and currency. Singapore and Australia are in development.
Do I need to create an account?+
Never. There are no accounts, no lead forms and no “get a quote” bait-and-switch — just your numbers, instantly.
