Quick Answers (Before You Email)

How accurate is the calculator?

Our calculations are based on industry-standard formulas. However, real-world conditions vary, so we recommend adding a 5–10% waste factor for best results.

Is my data stored?

No. We respect your privacy and do not store your project data unless a specific save feature is clearly provided.

Can I request a new feature?

Absolutely. We continuously improve our tools based on user feedback. Feature requests such as rebar estimators or advanced calculations are always welcome.
