Frequently asked questions
Everything you need to know before creating your plan or estimating your renovation budget.
Is the displayed amount guaranteed?
No. It is an indicative estimate based on 2026 rates. Only ANAH validates the amount when your file is approved.
Is my tax income stored?
No. The calculation is entirely local in your browser.
What if I am a Pink profile?
The per-measure route is not open to higher incomes. Reduced VAT may still apply to some work.
