Common questions
Is the calculator really free?
Yes. Every calculator on this site is free to use, with no account or sign-up required. Concrete Cost Pro ($79 launch price, regularly $99) adds saved rates, job costing, rate-health tracking and estimate history for contractors running an ongoing concrete business.
Does this replace an engineer?
No. This tool calculates quantity, cost and pricing from dimensions and rates you provide — it never determines slab thickness, footing size, reinforcement, concrete strength or code compliance.
Do I need to create an account?
No account is required for the free calculators or for Concrete Cost Pro. Pro data is stored locally in your browser with JSON export for backup.
